This report on the Diseases and Enemies of Poultry is written in answer to an extensive demand for intctr- niation on tlie subject of which it treats. While a larg-e number of articles on diseases of poultry may be found in poultry jouinals, live stock papers and poul- try books, there has been no recent attempt in this country to produce a comjirehensive, popular but ac- curate description of the 'diseases of fowls, together with the means to be employed to cure and prevent Ihem. In preparing the Jii-st part of this Bulletin, the Vet- erinai'ian has made free use of all of the works on dis- eases of poultry that lie has been able to secure, and has drawn upon the English, French and German litera- ture. Special acknowledgment must be given to the agri- cultural and poultry jieriodicals, to the following au- thors: Ztirn. Friedberger and Frohner, Neumann, Kail- liet, Nocard and Leclainche, and the publications of the U. S. Department of Agriculture by Drs. Salmon, Smith, Moore and Stiles. There is a great deal to learn in reference to^ these subjects, and a promising field for investigation and re- search is offered. It is hoped that some of the numer- ous imperfectly understood diseases of poultry may be carefully studied, and a future more complete report upon this subject issued under the auspices of the State De])artraent of Agriculture. (7) (8) PARX I. INTRODUCTION. IMPOHTAKOE OF THE POULTRY INDUSTRY Tha pi'odnction of e*?gs and poultry is one of the most important branches of agriculture. To those who have not given this subject especial attention, the state- ment that the annual poultry products of the United States are equal in value to the wheat crop, may ap- pear something startling. According to a recent estimate of the American Agri- culturist, based on the last census and on an extensive inquiry, the nuuiber of fowls in the United States is about 383,000,000; these produce U141,OO0,0O0 dozen eggs each year, and the value of both amounts to $343.- 000.000,00. Pennsylvania is one of the leading states in the pro- duction of poultry. According to the same authority, there are in this State 15,317,000 fowls of all sorts — rurkeys, geese, ducks and chickens— valued at $8,236, 000, and these produce 68,818,000 dozen eggs each year worth, at 20 cents ]>er dozen. |13,763,600. making a total value for ]»oultry and eggs of nbout $22,000. 000.00. At a very conservative estimate, one-tenth of the poultry, young and old. is carried away by disease each year. Hence the iiii]>oi tanc(> of this subject is mani- fest. (9) 1»--I 10 TREATMENT OF SICK FOWLS. A uunibcr of difficulties are met with in treating fowls that do not confront the veterinarian or live stock owner in treating most of the other domestic animals. Fowls are not accustomed to being handled. They are of a semi-wild disposition, so that when it becomes nec- essary during illness to examine and administer medi- (nne to them they are apt to resist. However, fowls can be treated as successfully as any other animals, provided they receive the same amount of careful, in- telligent attention. On all faims where poultry is kept in large numbers it is advisable to have a small building or room fitted up as a hospital for the care of sick and disabled birds. If such a place is at hand it will be possible to achieve much better results than when attemp'ts are made to treat fowls in the buildings where their companions are, and where they are constantly annoyed by them, or than can be reached if the fowls are placed in a dirty box in soine damp, out of the way place, under the impression that anything is good enough for a sick chicken. CAUSES OF DISEASE. The causes of diseases of }M)ultry are various and at- tention is directed to the cause of each one treated upon in the following. It will be noticed that in mcvst cases diseases are avoidable, tliat thev result from misman 11 agement in the way of feeding, liousing or cleanliness. Some of them, bowever, are contagious and cannot be wholly prevented even when the feeding and sanitary conditions are of tlie best, but experience teaches that where co-nditions are good for birds tliey are bad for disease germs and vice versa, so that when contagious diseases prevail, tlieir ravages are much greater among fowls that are poorly kept than among those that are cared for properly. Contagious diseases and })a,rasites are usually intro- duced by new fowls brought into the Hock, and it is worth while, especially where pure bred fowls are grown, to place all neAv acquisitions in quarantine away fi'om the flock for a few days, and until it has been shown that they present no evidence of disease. Great care should be used, also, in purchasing only from sound stock kept under favoiable conditions. SYMPTO.MS OF DISEASE. Birds shc'W disease in a variety of ways, but in most cases if the affection is at all severe, they become list- less, sluggisb, torpid, inclined to keep away from tlieir fellows, they are apt to stand with the head drawn down, the wings and tail pendant and feathers ruffled. Tn many diseases, diarrhoea is the first symptom, and in all cases of diarihoea, attention should be paid to the droppings for the ])urposp o>f noting their color and whether they contain A\'orms or an admixture of mucus or blood. Sometimes loss of apju'tite is the first sym])- 12 torn of disease, sometimes paleness of the comb and visible membranes. In the skin diseases, the first symptoms appear on the surface and consist in a loss of gloss on some of the feathers and stiffness and brit- tleness of the feathers, and sometimes the appearance of naked spots. The examination of the throat is important in manv cases because it is the seat of two common and very serio'us afflictions of domestic fowls,, namely, roup and gapes. In examining the mouth and thoat the bill can bo opened by pressing the thumb and finger on the angle at either side; then if the windpipe is pressed up- ward from the neck, the larynx can be forced into the back of the mouth and examined easily. It is fre- quently of advantage to have an assistant hold the fowl while the examiner carries out these manipulations and also holds the tO'Pgue down by bearing upon it with a wooden toothpick or some similar small object. The temperature of the fowl is rarely measured, be- cause fevej- is shown by symptoms of cliilliness, etc.. but it is well to know tliat the noa-mal temperature of the domestic fowls varies between 106 and 107.5 de- grees F. This is considerably higher than the tempera- ture of the larger animals. If it becomes desirable to measure the temperatuie. if: can be done by inserting a clinical thermometer into the cloaca. It should pene- trate for about two inches and remain two or three minutes before it is withdrawn and read. The heart beat of the fowl is quite rapid, varying from 110 to 140 per minute, but the determination of its rapidity is of liltle importance in diagnosing the dis- ease of fovsls, because when they are grasped for the purpose of counting the bent, it becomes so rapid that it is sometimes almost impossible to count it. running 13 up in manj' cases to 300 pulsations per minute. The heart beat can be easily felt by applying the fingers to the sides of the chest wall. The rapidity of respiration is of more importance than the rapidity of the lieart beat, because it can be determined at a distance from the fo-wl. and without anrjoying it and thus quickening this function. The normal breathing rate of the fowl at rest is from 50 to 60 respirations per minute. In diseases of the breath- ing organs and obstructions of them by growths or parasites, the respirations become quickened. POST MORTEM EXAMINATIONS. Very often it is not j)0ssible to determine the char- acter of a disease affecting fowls nntil after they are dead, and as many of the poultry diseases are conta gious, it is always advisable to open and examine every fowl that dies in the flock. This may enable the owner to check a contagious disease in its incipiency and avoid great loss. But in any case, it is advisable to know what fowls die from, so that similar occurrences may be recognized and prevented in the future. The ana- tomy of the fowl cannot be described at this time for lack of space, but anyone who is in the habit of opening and cleaning chickens, knows the general appearance of the healthy organs, will usually recognize marked departures from the normal. If fowls die from unknown diseases, and particularly if they die in large numbers from disease that seems to 14 be contagious, information in regard to these affections may be obtained by correspondence witli tlie State V'eterinariau, and it is desired tliat fowls dying from vague diser.ses shall be expressed as soon as possible after they are dead to the Veterinary Uepartment of the University of Pennsylvania, Philadelphia. They should be v.'ra}>i)ed in cloth and heavy paper, packed in straw, nailed up in a box with a cake of ice and ex- pressed as promptly as possible. A letter should always be forwarded either in the box or by mail ex- l)la!ning the general symptoms and characteristics of the disease. Such shipments may be made C. O. D. THE MEDICATION OF FOWLS. The medication of individual fowls is not ditticult, but requires care and patience. There are several forms in which medicines may be administered. Pills can be given most readily. It is only necessary to secure the bird, open its bill and drop the pill into the back of the mouth, then close the bill and if the bird resists, hold it together until the pill has been swallowed. Fluids are sometimes administered from a spoon, but if the fowl is badly frightened this may be a matter of considerable difficulty. The best way is to introduce a small rubber tube, about a third of an inch in diameter, into the mouth, pass it into the oesophagus and dow'n to the crop. A little ex])erience will enable one tO' do this quickly and without discomfort to the bird. Fluid medicines in any desirable quantity can be introduced through this tube. 15 Pasty mixliii-es are sometinip.s ^iveii. Medicines are mixed \Nitli sticky materials, as molasses, honey, etc., made into pasty masses and placed in the back of the mo-uth witli a small wooden paddle. Flocks can be treated, when the birds avIH eat, by mixing medicines with the food or dissolving them in water. Sometimes powders are given by si)rinkling them on moist grain. Chalk is frequently given in this way to birds with diarrhoea by mixing it with rice that has been moist- ened. It thus adheres to the kernels and is eaten with- out reluctance. When a very iAck fowl is under treatment, it is bet- ter to give small doses at frequent intervals than large doses at long intervals, for in this way the action of the medicine can be measured more accurately and the proper dose can be ascertained by trials. Fowls of different breeds and different sizes and ages require different doses. It is not always possible to determine these accurately, but the judgment cf the poultry keeper must be called into play in all instances. DISINFECTION. Disinfection is alluded to very frequently in the fol- lowing pages and is often of the greatest importance. Many poultry keepers are under the impression that it •s sufficient to scatter strong smelling jmwders or li- q.iids about the cC'0j)S or poultry houses, and that so long as the odor of these materials is in the air. the premises are undergoing disinfection. Nothing could 16 be more inisJeadii'g or further from the truth. Disiu fection is practised for the purpose of destroying dis ease producing germs and disinfectants, or the mate- rials used for disirfeeting, will only destroy germs that they come in eortact with. It is perfectly evident that when disinfectants are scattered about carelessly tkey oome in coDtact with a very small fraction of the entire surfaces that may harbor germs, and unless all of these surfaces are covered and all of the germs reached the disinfection is apt to be fruitless. In order that dis- infection may be carried out properly it is essential, ilrsit of all, to remove the manure, litter and rubbish of all /dnds. This should be mixed with lime and placed in barrels, or it should be spread on fields at such a dis- tance from the poultry runs that it cannot possibly contaminate them. However, if the disease is a viru- lent one it is always best to bum manure rather than take any chances with it. Then the interior of the building should be thoroughly swabbed or scrubbed out, and afterv. ards the disinfectants can be employed. Disinfectants are best used in solution because they can then be applied more evenly and perfectly. They can be a])plied with a Itrush, with a sprinkling pot or, best of all, with a spray pump, such as is used for spr.aying fruit trees. The disinfectants to be employed in special cases are mentioned hereafter in connection with the prevention of the different diseases. White- wash is always a good disinfectant, but its value can be greatly increased for this purpose by adding chloride of lime to it, one pound to three or four gallons, or car- bolic acid, one pint to the bucketful. CHAPTER 1. DISEASES OF THE SKIN, A. I'hoae caused by parasites. 1. FLEA8. The bird Ilea, known as Pulexavium, is a very small, brownish insect. It has six legs but is without wings. Its body is somewhat elongated and flattened from side to side. This little parasite is exceedingly annoy- ing to poultry and especially to pigeons. It is very active and lives not only on the bird but also on the perches and in the nests and crevices of poultry houses. By its constant biting it keeps fowls awake and causes them to scratch and hop about so that their rest is disturbed and eventually they become thin and weak and if they are not actually killed by the fleas, which occurs very rarely, they are so harassed tliat they are predisposed to other diseases and in this way the flea may be an indirect cause of death. Pig- eons are annoyed by fleas far more than other poultry. The remedy is to al- 2-1 Labva or THE Chioken Flea. Twenty times natural slze.l (17) 18 low llie birds a (lusliug J)1ucl' and if the parasites are very nmueroiis insect powder or sulphur should be mixed with the dusi and when the fowls scratch and burroiw in this i^owder it enters the spaces between the feathers, reaches the skin and so obstructs the breath- ing openings on the surface of the flea that it finds the conditions very disagreeable and becoines stu])efied and falls off or goes away. Or insect powder can be blown by means of a powder gun or blower between the feathers of the alflioted fowl. It is also necessary to so treat the roosting places, nests and poultry houses that the fleas will be either destrojed or driven away, liecause if this is not done they return to the birds as soon as the dust is shaken from their feathers. Disinfection can be accomplished by spraying the interior of the building with a solu- tion of carbolic acid (one part to twenty parts of water). Or a kerosene emulsion, such as is used for spraying fruit trees, can be employed for the same pur- l)ose. Head op the Chicken Flea. Thirty times natural size. 2. LTOE. Bird lice differ considerably from the ordinary lice of haired animals. They do not suck blood as those do and cannot, for they are proyided with a mouth 19 that ouh" eiables llioin to bite. Tliey live on the crusts, scales and dead cells that gather on the surface of the skin and that are prevented from falling off by the featliiers. There are several vai'ieties of lice belonging to four principal genera: these are Goniodes, Goniocotes, Lip- eurus and Menopen. While these parasites differ eon; siderably as regards their shape and size they resem- ble each other very closely in their habits. All of them are very small insects, from 1-100 to Id incli l&ng and their bodies are plainly divided into three I)arts; the head is very large and fiat, the thorax, or second segment, is roundish and considerably smaller than the head ; the abdomen, oi most posterior segment, is long, oval and plump. Their color is usually grayish or yellowish, but some of them show differ- revent sleep and rest so thai fowls and especially young ones do not grow and thi-ivc' as they should, and Ix'comc thin and delicate. In this condition they do not produce eggs noir are they good for food, and so long as they con- tinue to remain badly infested with lice they are ab- solutely unproductive and worthless. The conditions that are most favorable to the pro- pagation of lice have already been mentioned briefly. 21 Attention should also be called to the fact that poultry houses that are dark and damp fninish very favorable places for the growth of these insects. Tlien, also, fowls that are poor in condi- tion are jnore apt to be in- fested with lice than those that are in goiod condition, healthy and sturdy. It has been noticed fre(iuently that where there are a number of fowls in an infested pen tlnose that are least rugged harbor tlie most lice. The probable reason fcir tliis is that fowls in poor condition have a somcAvhat drv and „ ■ . Chicken Louse. SCniTy Skm which provides CJonwcotes hrAouastei; male. Forty times natural size. more hiding places and more food for lice than the smooth, pliable skin of the perfectly healthy bird. When fowls are afflicted in this way it can be noticed that they are uneasy and restless, they are constantly pecking at different parts of the body and scratching and shaking themselves. They also have an inclina- tion to dust themselves and when caught and ex- amined the lice can frequently be seen, when tlie feath- ers are spread apait. and especially about the head and neck, where they cannot be reached by the bill of the animal, beneath the wings and sometime* on all parts of the body. They may also be found in many cases, if a careful search is made, in the nests, on th<' perches and in cracks and out-of-the-way places at any point in the building. In attemjiting to destroy lice it is necessjiry not only to treat the fowl but also the j)remises occu]iied by it. 22 because if we simply destroy those that ane on the bird they will retiini aj^ain from the surroundings just as lleas do. In treating an animal lor the purpose of destroying lice two metliods may be employed. We may use substances that will poison the lice outright or we niay use sub- stances that are not poisonous in themselves but which destroy lice by obstructing the jiores on the surface of the insect and thus shutting off its supply oif air and suffocating it. The latter plan is pieferable in the case of young and weak birds. Little chick- ens but a few days old frequ.Mitly ^"^ ^^^°g^f '^'"'^^ accpiire lice from their mothers or L'pcurmvm-iabiUs, their surroundings and are sometimes annoyed ser- iously by them. In these cases it is advisable to apply a siuiall quantity of bland oil, such as sweet oil or cot- ton-seed oil, to the chicken's head and perhaps to the sides of the neck if the i)arasites are very numerous, or lard maj be used for the same puri)ose. In the case of older fowls sulphur ointment is a very efflcient remedy. It should be applied in small quantity about the head, sides of the neck, beneath the wings and around the vent. Or insect powder {pyrethrum) may be blown be- tweent the feathers and this will destroy or drive away the lice. If the fowl is to be liberated immediately af- ter the powder is apjjlied it is well to first dampen the feathers so tiiat ii will not be at once sliaken oft\ A dust bath should always be provided, and this goes a very long way toward keeping fowls free from all sorts of skin parasites. It is frequently advisable to add in- sect x^O'Wder oi' sulphur to tlie dust. 23 Ncuiiiaiin records a c. a s o wlicie a fariiUM* took Ihe plaster fioiii a l)uildinot about the ueelc O'l- ou the head.

If they are pulled off it is found that the skin beneath is red and bleeds easily. As a rule these areas do not ilch, but sometimes they do, and then the bird scratclies them vijxorously.

When feath- ers are pulled out ou the border of the diseased area it is noticed that the lower end of the sheath is covered with scaly^ layers and the i)arasite can usually be dis- covered among them. SchaelTer has recently reported a case where this disease ajjpeared among a Hock of 70 hens and nearly all of them lost all of their feathers, with the exception of those in tlu^ wings and tail.

Tlic pens were re-arranged and cleaned and the fowls were sprinkled twice a week with a weak solution of creolin poured on to them from a watering pot, with the result that in about four months they had recovered and feathered out again. The treatment to be employed in these eases is first of all to isolate the afflicted fowls. Then disinfect the premises that they have occupied, and afterward give them individual treatment if they are worth it. The local treatment consists in the application to the diseased skin of remedies that will destroy the para- site pi'oducing the disease. One of the best applica- 32 tio-n.s for this j)iirit().s<^ i.s a solnlion of balsam of l*eru in aJc(>hoI (1 part to 5). This can be applied Avith a sponge oi' soft brush, and should reach not only the diseased area but the healthy skin for a distance of about an inch on all sides. Another eflicient applica- tion is sulphur ointment, or a solution of creolin (1 j)art to 50) may be used, but shctuld be ap])lied lij^htly and not rubbed in, because if apjilied too fieely or energetically it may poison the fowl. .'j. PROTOZOA. liarnyard f(>\vls, tr.ikeys. and especially pigeons, are sometimes attacked by a peculiar wart-like growth That apiicars about the head, the base of the beak, the eyelids and ilie orifices of the nose, and sometimes spreads to the base of the wings and the general sur- face of the body. These growths are yellow and smooth and resemble the warts that frequently appear on the hands. They are contagious, spreading from one bird to another, usually slowly, but sometimes with considerable rapidity, and aie caused by a minute animal parasite belonging to the Protozoa. That these growths are contagious has been fre- quently proven by experimentation. One of them can be removed and a small portion of it rubbed over the scarified skin of a healthy fowl. Within eight or ten days the surface will show a perceptible elevation at ihe point of inoculation, and a few days later the new warty growth ^^ill be plainly developed.

The English poulterers sometimes refer to this disease as a pox of the chicken but this designation is very misleading because fowls do not suffer from pox in the sense that maniirais do. The remedy for these warts is to remove all infected birds from the pigeon loft, renew the nests, clean the interior and treat the individual by burning the wart out with a hot iron or apply tincture of iodine or tur- pentine. Creolin is also efficient, but it is neces.sary that the top of the growth should be sliced off before the creolin is applied, then by placing a drop on the end of the wart and reneAving the application every three or four days as long as necessary, the condition may be permanently ciii-ed.

In some respects lliis disease i-eseiubles inaiiti:<\ It is, however, produced by an entirely different parasite, and on dose exsnMnation it can be seen that the condi- tion of the skin is different from that whicli exists in mange. The parasite of favns is a vegetable «j:rowth, known as Acho- rion schorleinii, Favus usually com- mences about the comb, head and neck. It causes the feathers to become brittle and break off and fall out, and when these are examined clO'sely it is seen that their interior is filled with scales and with branching threads cesembling minute roots. These are the filaments of the vegetable parasite or fungus. When the comb is involved, it becomes swollen, its surface be comes scaly, whitish and powderly. The eyelids are frequently afl'eeted, ajid in some rare cases the feath- ered surfaces are involved to such an extent that the bird becomes almost naked. tTpon the skin there de- velops a thick yellowish or grayish crust or scab in the form of rather small, roundish disks, depressed at the centre.

The redness may continue for several days and Mmw feathers mwy droj) from the affected parts. This condition is not very serious, and can easily be remedied by ap])lying mild ointments such as the oxide of /inr ointment or cosmoline. The removal of tlic canse is usually sniticieut to etfecl a cure. 37 1'. INFLAMAIATIOX OF TIJK .^KIX. The eai:ses of ilie previous aifeetioii when uimsuallv severe, w when they rontinue to net for a considera- ble time, piodnce not only the mild condition above described, but also an inflammation of the skin that is miore or less intense. A similar condition may re- sult from the accumulation around the posterior por- tion of the body. In cold weather these accumulations alternately thaw and freeze and pull upon the feath- ers they are attached to, thus leading to an inflanima tiou of the adjacent skin that can be recognized by red ness, swelling, tenderness to pressure and discharge from the surface. The remedy consists in cleansing the skin by the use of soap aiul water, cutting off the feathers if necessary, and then ap])lyiug the ointment al>ove mentioned. DISTrKP.ED MOULTING. During the spring while fowls are shedding their feathers they ai'e in a delicate condition and are moae apt to become diseased u])on exposure to deleterious influences than at any other time. Their tendeniess and loss of vitality is shown by the fact that they lose their spirits and activity to some extent. Their ap pptifps ai'p somewhat ca]>rioious, and the ]H'oduction of eggs falls off very greatly. If the loss of c(mdition iit this time is iiuusually great, or if the fowl is poorly nourished or weukeued fixjiu any cause, moulting is retarded and the old feathers remain in the plumage, giving the fowl an unkempt, faded, weathei'-beaten ap- pearance. This result is frequently dependent upon improper feeding at this critical time. To achieve the best results, fowls must ahvays be fed carefully and their rations should be as nearly bal- anced as possible. During the moulting season espec- ial care is neecessary, and the food should be more tiitrogerous than at other times. Unless fowls have the material in them and in their food for the produc- tion of new feathers the old ones will not be shed. In order that unusually nutritious food may be thoroughly digested it is necessary that the fowls should have free exercise in the open air, but they should also be protected from bad weather, from cold rains and ^^hen delicate should be housed early in the evening. A diet containing meat, either raw or cooked, and bones, is appropriate for moulting fowls, and it is also well to give some stimulating food, such as chopped onions or garlic, or a small quantity of pepper. Some of the English poulterers recommend stale bread soaked in ale for valuable fowls during the moulting season, and the Douglas mixture is also in high rejtute among them. This mixture is made by dissolving 1 oz. of sulphuric acid and half a pound of sulpliate of iron in two gallons of water. One or two table.^poorsful of this solution are placed in each pint of the drinking water, and the effect is that of a genth^ tonic. One should always pay pai"ticular attention to the cleanliness of I he poultry house dui-- ing the moulting season, bccanso if lice or mites ai-o [)rpsent then they will do moi-e hai'ni than at other times. 39 4. OBSTKUCTION OF THE KUMP GLAND. There is a glaud at the poiut of the rump that se- cretes an oily substance that tends to keep the feath- ers in this region oily and sleek. This gland is the largest of the sui)erficial glands of the body and some- times the orifice through which it discharges its secre- tion becomes obstructed. Then the region of the gland swells and becomes painful. It may swell to such an extent that it reaches the size of a walnut. This causes considerable ])ain, the afflicted fowl be- comes sluggish and generally indisposed and when it is caught and examined the local swelling can be readily disoO'vered. If the gland cannot be emptied by gentle pressure a small incision should be made into it with a sharp knife and its contents removed. If, however, the con- dition has existed for a long time, the gland may fill with a thick, cheesy-like material that cannot be stpieezed out. It then becomes necessary to make a somewhat larger opening and scoop the substance out with the handle of a small spoon or some similar ob ject. Then the cavity should be washed out by in- jecting into it a vei'y weak solution of carbolic acid d part of carbolic acid to 200 of water), or a solution of boracic acid (15 grs. to the ounce). To prevent the parts from becoming hard while healing an ap])lica tion of oil or cosmoline should be made. 3-1 CHAPTER 11. DISEASES OF THE BREATHING ORGANS. A. — Those caused by parasites. 1. GAPES. Gapes undoubtedly destroy more young chickens than any other disease. Tt is a disease caused by a small worm that occu])ies the upper air passages. This womi \\as first discovered near Baltimore by Wiesen- thal in 1791). Sicce then it has been described by nu- merous zoologists and is at present found in all parts of this couuti-y and Europe. All of the domestic fowls Gape Worm.— Syngamustrachealis. Natural size and five times natural size. are attacked by it and some of the semi wild birds. In Europe it causes great loss among the pheasants. 41 The worm is kiio\\u as Syngamous irachealis, is of a reddiish color and the feiiiak^ is about Gine-lialf to three- fourths of an inch long, while the male is about one- fifth of an incli long. The male is constantly attached to the female, the fuuuel-shapped lower end surround- ing a pore on the side of tlie female a little less than one-tliird of the distance from its head. On account of this ])eculiar iiiiion a gape-woi'm is sometimes de- scribed as a "branch-worm" and on account of its color it is in some places known as the "red-worm." The head is broad and flat and arianged for sucking. This disc-lilve liead is placed against the lining membrane of Ihe wind-pipe at any point between the mc'Uth and the bivnchial tubes. Souietimes there are as many as 30 or 40 worms in a single fowl, but usually not so many. Three or four of th(-m suffice to destroy a young chick but a greater number are nec- essiary to destroy an adult. When tlie worms are coughed out othcM' fowls eat them greediiy and in this way they become infected in turn, because the miature females are full of eggs. It has been shown by experiment that after birds are fed upon worms containing eggs they may develop gapes within two to three weeks. Another and per- haps the principal way in which the disease is spread is through the agency of earth- wonns. Many of the eggs of the gape-worm when a pair of gape worms throAvn out on the ground gain ac- ti'S'n ofTvi™ Vivy^ 42 cess to the icteiioi" of tlie earth-worm, then when the earth -woiin is eaten by a chicken yonng gape-worms develop from these eggs and the chicken becomes dis- eased. Some of the gape-worms are partially couglicd up and then s^^ allowed by the fowl; the eggs in them pass thrO'Ugli tlie digestive tract and are voided with the faeces so that in this ^^'ay. also, the soil of the barn-yard or the water may become contaminated. The symptoms of gapes are very easy to recognize. Tlie afflicted fowl has difficulty in breathing; it opens its mouth frequeitly and gaps, or gasps for breath. This manner of O'pening the month is the characteris- tic from which the disease derives its name. There is some coughing accompanied by the expulsion of frothy slime. Somietimes the miature wonns are coughed out. The afflicted bird loses its spirits, it stands about with the feathers ruffled and head down, at intervals opening its mouth as thcugh gasping for air. If there is am* doubt as to the nature of the dis- ease an examination of the throat should be made. Tliis is done by catching the bird and holding the moutli open by pressing with the thumb and finger on each side of the beak. This forces the mouth open and exposes the throat. Then by introducing a small ob- ject to depress the tongue the larynx may be exposed ajul the interior examined. Pressure upon the larynx from below will force it up into i)lainer view. Death results in some cases quickly, from suiTocation, and in other cases slowly, from exhaustion and secondary dis- eases. When this disease appears in a flock, the afflicted fowls should at once be removed in order to ])i'event the distribution of the parasite. The worms <'an frequently be removed from tlie wind i>ipe by in- troluoiiig a In^op mndo by doubling a hois(^-li;iir. ITiis r.', when iiilioduced and liirucd aiOLiiid disl(*dg(,*s tlie warms and draws them out. Or, a feather from which all of tlie barbs have been removed with the exception O'f those at the point, may be nsed for the same pui'pose. Some recommend a timothy head from which the sedds have been remoA'ed by rolling between the hands or by shaking-, but tliis is so large that it is difficult to use it except in mature fowls. For chickens, the pro- jections on the lower part of the timiothy head may be removed and onl}' those on the tip alloAved to re- main. This appliance has the advantage over the horse hair and feather that its siharp s])ines oi' hooks are miore likely to adhere to the worm and permit its removal. Some- times oil or turpentine are applied to these various in- struments before they are introduced into the wind- pipe. It is advised in some cases to cause the diseased fowls tO' inhale tlie smoke of tobacco. This is done by ])lacing them in a closed box and blowing smoke into it from a pipe. Tlie worms are in this way stapefied luit unless care is used tlic fowls will also '^'^'^ wind i>ii»k of a Pheasant, UbtU im lOVMN >M11 <^li^S>U (^p^Qpg^j^^j^^jj^,jjyjj^,^j J Y, SHOWING be stupiiied and pcrliaps^^Pf^^^oRMs attachei. to its in- 44 suffoiiatod. Ho^\evel•, tho fowl can stand mwe to- bacco smoke tlian the worm so that after its release from the box it usually coughs up the wealcened para- sit'^^s. Powdered lime is also used for removing the gape worm by dusting it in such a way that the fowl is caused to iiLhale some of the fine particles. Some times the fo\Als are placed in a box over which a .sheet of muslin is spread and lime is sifted throug-li this Hidslin top and the fowl is obliged to inhale the dust. This procedure is somewhat dangerous unless great care is exercised, and cannot be very highly recom- mended. In the A\ay of internal treatment, camphor, asafoet- ida and garlic are all of value. Camphor should be given in pills of about one grain each. Asafoetida should be given in one grain pills and garlic should be chopped in flue pieces and fed with the food. Tlie treatment of the soil over which the infected fowls roamed is of great importance and especially if they were kept in confined .spaces. By treating the soil with lime and spading or ploughing it up fre- quently the eggs of the gape-worm may be desti'oyed. Or the ground may be thoroughly soaked ^^'ith a solu- tion of sulpliuiic acid Cone part to one hundred). The water troughs and feeding places should all be thor- oughly cleansed and disinfected Avilh coperas solution (one pound to two gallons of water). The bodies of the dead fowls should be buried deeply at a distance from tlie barn-vard. or burned. 45 2. DISEASES OF THE AIR PASSAGES CAUSED KY MITES. There is a minute parasite similar to tlie parasite of mange that infests the air passages and specially the windpipe, the bronchial tubes and the large air spaces in the chest. It is known as Cytodties nudus. Sometimes these parasites penetrate beyond the air sacs and reach the air spaces in the bones. When present in large numbers, they cause an inflammation of the parts they infest, but when pre.«»ent in small Thb Air-sao Mite of Fowls. Cytodites nudus, one hundred times natural size. numbers the}- seem to produce no disturbance. The disease produced by (hem in the bronchial tubes is of, the nature of a bionchitis of a severe type and some- times there is inflainmatic-n of the lungs, or pneumonia, 46 as well. Tiiese conditions are indicated bv difficult and rapid brcafhing and, Zurn says, by a peculiar tone that is similar to that produced by fowls when a for- eign body ei.ters the windpipe. Otherwise the birds seem lively and have a fairly good appetite. It is only when tliese parasites are present in enormous num- bers that the disease they produce is sufficiently severe as to cause death. The treatnu'ut of these cases is not at all satisfac- tory, so that it is cheaper in the end to destroy the afflicted fowls than to attempt to cure them. Upon opening a bird that has died of this disease the para- sites can be seen in great abundaiice in the parts men- tioned. If treatment is attempted the inhalation of the vapor of tar or of burning sulphur is as promising as any- thing. 3. PNEUMONIA CAUSED BY MOULDS. Several varieties of the common moulds that grow so plentifully in dark, damj) places have been known to enter the air passiiges of fowls, penetrate to the lungs and grow there, causing a fatal pneumonia. The moulds that have been discovered in this k>cality are of ihree viuieties of Aspergillus and one of Mucor. It is probable that they enter the lungs in the form of dusl. because their spores are exceedingly small and could readily pass into the lungs in this way. Then, if they find the coiiditious there favorable to their growth they multiply and cause little spots of disease 47 wherever they grow. Sometimes thev spread out over the lining membrane of the air tubes and cause a diffuse inflammation and thickening that somewhat resembles the change that takes place in diphtheria. In the lungs, the growths are characterized by the ap- pearance of little round nodules, where the tissue dies and becomes yellowish and of the consistency of cheese. In old cases, these spots sometimes become loaded with lime salts and then they are ha id and even stony. Tlie principal symptom is difficult breathing. The respiratory movements are rapid and accompanied by a hoarse sound. The appetite is diminished, the spirits are depressed, the bird is disinclined to move, its feathers become ruffled, it loses flesh rather rapidly and towards the end develops a diarrhoea that hastens it to its fatal termination. The entire course of the disease is rallier long and usualh' covers several weeks. Tr'eatment in these cases is not to be recommended because the outlook for recovery is poor. However, if anything is done the best results can be obtained by causing the bird to inhale the vapor of iodine. This plan of treatment is carried out b}' mixing equal parts of tincture of iodine and hot water. The steam as it rises can ies the iodine vapor and by holding the vessel beneath the bird's head it is obliged to inhale this medicine. Iodide of potash may be administered in- ternally in doses of one to two grains twice daily. It is far better, however, to prevent the disease than to allow it to develop and then attempt to cure it. When it is remembered that moulds occur principally in damp, dark places, it will be seen that good drain- age, ventilation ai>d light will prevent their growth and thus ward off the disease. Disinfection and white- washing are also of the highest value in this direction. 48 B . Those not caused by parasites. 1. OATAKKH OF TJIE NASAL PASSACiKS. "I'll'.' All sorts of fowls, and especially the joiiug, take cold easily wheii exposed in damp i)laces. An earth lloor in the poultry house, particularly if it is poorly drained, is a fruitful source of colds. Poorly con- structed buildings with cracks in the walls or broken window panes, permitting a draught to blow through and strike the fowls while roosting at night, is a com- mon cause of cold. Odds are recognized by the well-known symptoms of discharge from the nose, sometimes also from the mouth, swelling of the eyelids, depression of spirits, shown by disinclination to move about actively, marked loss of appetite, inclination to stand in a warm, bright place, with the head drawn down and feathers ruffled, and, if the fowl is a laying hen, cessation of egg production. Since the nasal passage is stopped up the fowl breaths more or less through the mouth, and this may lead to di-yness and hardening of the tip of the tongue. This condition is often described by poulter- ers as ''pip," and especially when young chickens are affected. The treatment is simple and consists first of all in bettering the conditions to which the fowls are sub- jected, and thus removing the cause of the disease. Holes in the ro^of and jsides of the buildings should be patched, broken Avindow ])anes replaced, and if it is not |)0ssible to keep the flcoi- of tlie ])oultry house dry at all times it should be removed to another location. The fowl should be placed in a warm, dry cooj), where 49 the sun can shine in freely, supplied with small (]uaii- tities of tempting food and clean water in clean v«'s- sels, to which may be added a small amount of chlorate of potash (15 gTS. to the pint). A little onion or gar- lic in the food is also of advantage. If the discharge from the ncse collects about the orifices and obstructs them, or if the eyelids are swelled to sucli an extent that they cannot be opened, the collection of matter should be removed by means of a spoaige or soft cloth moistened with ^\arm water. 2. LARYNGITIS AND BRONCHITIS. SORE THROAT. If the cold is of an especially severe type, on account of the fact that the exposure to which the fowl was subjected was intense or of long standing, or if the fowl is young or of a naturally weak constitution, the membi'anes of the air passage may become afflicted with catarj-h that reaches beyond the head into the throat, and into llie branching bronchial tubes that penetrate the lurgs. In these cases, the discharge from the nos<:' is more profuse, the depression of the fowl's spirits is greater, there is considerable difficulty in breathing, and in severe cases the bird m.ay gasp for breath very much as though its windpipe were ob- structed by gape worms. The general ti-eatment in these cases is the same as for pip, but more attention should be devoted to the fowl because it is in a more serious condition. In 4-1 50 place oi cl'-loratt' of potash in tlu' di-inkinj;- water it is better in these severe eases to add small (jnantities of baking soda (bicjirbonate of »oda) and Ulauber's salt (i dracUni to each pint). It is also of advantage to give small doses of sal ammoniac (1 grain) mixed with honey. Since roup, a very contagious disease of fowls, com- mences in a similar way, it is very important to imme- diately remove from the Hock all birds showing the symptoms described above, because if it should j»rove that they were afflicted with roup the extension of the disease might in this way be prevented. a. LUNG FEVER OR PNEUMONIA. If the exposure to which a fowl is subjected is of an unusually severe character, it may result that the bird will develop inflammation of the lungs oa- pneumonia. Symptoms of this very severe affection are at first sim- ilar to those of the two preceding diseases, but they rapidly become worse, and within a short time the patient evirces great difficulty in breathing. It loses all ambition and sense of fear, remains stubbornly in one place and when caught and examined it will be noticed that the muscles in the lower part of the body, those of the abdomen, contract and expand with each respiration and in this way assist the muscles of the (^hest to expel and renew the air in the diseased lungs. Pressure on the sides of the bird will cause considera- ble ]>ain. If the fowl dies, and unfortunately most of 51 them do when afllicted with pneumonia, it will be found that the lungs are very red and full of blood, and portions of them when cut off and placed in a vessel C'f water will sink instead of floating as pieces of healthy or slightly diseased lungs do. The air tubes are filled with a yellowish or reddish frothy fluid which in some eases is expelled in small quantities during life. The treatment of these cases is not profitable, be- cause so few of them recover. If, however, one wishes to treat an especially valuable fi^wl, and will consent to devote the time and care to the ciisc rliat it requires, good results may follow. Half a teasyKtoT.ful of whiskey in a little warm water, together with from 2 to 3 grains of saltpetre and ammonium carbonate may be administered at in- tervals of frcm three to four hours. It is also well to cause the fowl to inhale fumes of burning sulphur, but ihis vapor should not bo administered in a concen- trated form. The fo'wl must be kept in a warm, dry place. ;i* 1 CHAPTER III. DISEASES OF THE DIGESTIVE OR CANS. A. Those caused by parasites. There are a great many parasites that iufest the di- j^estive organs of fowls. Some of these are of but lit- tle moment, because they occur in small numbers and do but little harm; while others are of the greatest consequence because they are sometimes exceedingly numerous and seriously affect the health of the af- flicted bird or cause death. The number of parasites that sometimes infest fowls without producing appre- ciable effects is almost incredible; while in other cases a much smaller number of parasites of the same species may not only cause great inconvenience but may destroy the life O'f the infested bird. So it is evi- dent that the effects of parasites depend not only upon the number and activity of the parasites themselves, but also upon the strength and resisting powers of the bird affect<*d TTsually. Ilic nun.bc-r of fowls in a flock that harbor parasites of the same kind is considerable. So that when one (vf a tlock is killed by parasites, and the cause (52) 53 of death is disclosed by a dissection of the bird, it is fair to assume that other fowls that present the sjnap- toms shown by the dead one, suffer from the presence of the same kind of parasite. Of all varieties of poultry, guinea fowls and pea fowls are least subject to the ravages of parasites. Of the other varieties, those that live on dry land seem to be more troubled with parasites than those that swim in The water, as ducks and geese. 1. TAPEWORMS— CESTODES. A tapeworm is a row of more or less distinct organ- isms joined together in the form of a band or tape. At one end there is a s»omewhat conical or globular segment supplied, at its free end, with four suckers, and in the center between these with a crown of thorns. This segment is usually termed the head of the tapeN\orm, but in reality it is not a head for the tapeworm has and requires no head. It has no mouth, no eyes, no nervous system, no intestinal canal. It derives its nourishment from the Huids surrounding it by absorbing them through its outer skin. The first segment; popularly termed the liead, is known in scien- tific language as the Scolex, and its function is to at- tach itself to the lining membrane of the intestines by its suckers and hcoks. and by a process o-f division de- velop tapeworm joints from its other extremity. 54 The s;('<;ineiils close to the scolex are siuull aud immature, further away they are larger and more developed, at the end of the chain they are ma- ture or ripe. The ripe segments are >• detached from time to time and pass ► into the contents of the intestinal ^ car.al and escape from the body g with the faeces. These mature seg- ^ raents are provided with contractile ^ fibres in their walls and are able to % move about. They contain eggs. "C Their- life outside of the animal in & which they are developed is short, and s when they die and break open the | eggs escape. If these fall in a damp 2 place, thev retain their vitalitv and c power to mature for a long time, in | some cases many months. | A remarkable and interesting fact^l in connection with the life historv of I the tapeworm is that the eggs will not develop into mature worms in the body O'f an animal belonging to the species of the one in which they were produced. It is necessary that they should first enter the body of an animal of a different species and there develop into embryos, whicli ])ass through the walls of the intestinal canal and j)enetrate to distant parts of the body. There the embryos remain in a some- what more advanced state of development until their host dies and is consumed by an animal belonging to th(^ species of the original host. This can be illustrated bv brief! v describing the life 55 history of one of the comimou tapeworms of man {Tcenia soleum) usually called the "pork tapeworm." The eggs from the mature tapeworm oi this species pass from the body of a person harboring it and some of them are consumed by swine. They hatch out in the stomach or intestines of the swine, penetrate tlie intestinal walls and reach the muscular portion of the animal. There, they constitue the so-called "bladder worm" or "measles" of pork. The hog is slaughtered and if its flesh is eaten raw or imper- fectly cooked, the consumer £• swallows the living parasites g which develop in the intestinal 5 canal into mature tapeworms, o In the same way it is neces- > sary for the tapeworms of fowls o to pass through the body of an ^ intermediate host before they g can re-appear as tapeworms in | fowls. It has been shown by 5* definite experiments and numer- 5 ous observations that the inter- o mediate hosts in some cases are *^ small animals such as snails, ^ molluscs, worms and insects § and it seems probable that these ^ animals are the intermediate % hosts for bird tapeworms in all ^ o cases. » s A single ta]>eworm in the in- " testinal canal of a fowl may do no harm. But when they are numerous symptoms of disease appear. One of tlu' 5fi first effects is the initatioii of tlie momhrane lining; the digestive tract. Tliis produces diarrhoea and may lead to loss of liesh. Znrn lias observed that towls af- tlicted with tapeworms have an unusual thirst and an especial lilcing- for co-Id water of which they drink large quantities and he claims that this symptom should always be regarded with suspicion. In time, as the re- sult of the continued irritation of the intestinal canal and the fact that much of the nourishment that it con- tains is diverted to the worm and lost to the fowl, the bird becomes weak and thin. Its droppings are fre- quently mixed with mucus and sometimes with blood. A close examination of them sometimes reveal seg- ments of the tapeworm and a careful microscopic exam- ination may reveal eggs in large or small quantities. Sometimes the tapeworms indirectly produce an irrita- tion of the nervous system that is characterized by fits. If the afflicted fowl dies, it will be fonnd that its organs are pale and contain but little blood. If the intestinal car-al is opened the tapeworms can be dis- covered hanging by their thin ends to the mucous mem- brane, with the rest of the body floating in the canal. It is easiest to discover the wonns when the intestine is opened with a pair of scissors while it is held below the surface of warm water. Illinger has described an outbreak of tapeworm dis- ease among geese that was so extensive that it be- came almotst impossible to raise these fowls in a cer- tain district. When the goslings reached the age of ten or twelve weeks they would commence to become thin, notwithstiinding the fact that their appetites con- tinued good, and finally they would develop epilepti- form fits and severe diarrhoea and shortly thereafter would die. Death usually occurred within two weeks after the appearance of the first symptoms. T'pon r)7 dissecting tliese birds, tapewoiuis (Taenia lancolata) were found in the intestines in great numbers. As to the treatment of fowls afflicted witli tape- worms, a large number of remedies are recommended and used with more or less profit. One of the standard remedies among European poul- terers is powdered bark of the i>omegranate root, of which one teaspoonful is apportioned for the feed of eacli fifty chickens. Powdered areca nut may also be used in doses of from thirty to forty grains, mixed with butter to form a pill. This quantity should be administered to each bird, but it is not a good remedy for turkeys. Dr. vStiles of the Bureau of Animal In- dustry has recently experimented with the oil of tur- pentine as a remedy for fowls and finds that the larg- est safe dose is about one tablespoomful. This remedy is very useful for the purpose of removing parasites of all kinds from the intestinal canal of most of the do- mestic animals and it is altogether probable that it will prove of considerable value in treating fowls with tapewoi-m. It should be followed by an equal quantity of castor oil. As with most other diseases of poultry it is very much better to prevent than to attempt to cure, and knowing what we do with reference to the development and life history of tapeworms, it is quite possible, in n ost cases, to avoid their effects. To prevent tapeworm disease among fowis it is im portant, first of all, to keep no birds in the fiock tliat are supposed to be infested by tapeworms. It is also important that fowls should not be allowed to roam where other fowls are known to have contra ctcd or carried these parasites. Especial attention sliould be devot-3d to the removal of droppings of fowls that may ])Ossibly be infesttd and these dro])]>ings should eitliei- be destroyed or treated in such a manner that the tape- 58 worm eggs in Iheui in;iy bo killed. This can be done by disinfecting tliem with a strong solution of carbolic ucid, quicklime, or as Dr. Stiles suggests, by keeping them in a dry place for several months or through the winter, for it is probable that they can not withstand this treatment. If fowls are raised on fresh uncontaminated land there is but little danger that they will become in- fected. Dr. V. A. Moore, of the Bureau of Animal Industry, lias recently called attention to a peculiar disease of chickens that is characterized by the development of small nodules in the walls of the intestine. These nodules ^\ere about a sixth of an inch in diameter and quite hard. AVhen opened it is found that the larger ones contain greenish pus. Tliese nodules were pro- duced by a small t?peworm recognized as Davaince tet- ragona. Tliis dis &se has been recognized in fowls from the District >f Columbia, North Carolina and Virginia but has nut as yet been discovered among the poultry of Pennsylvania. It is quite destructive. 2. SUCKING WORAIS— TREMATODES. These woims are of an oval shape, have rather phnnp bodies and are provided on their ventral sur faces with suckers by means of which they attach themselves to the part they are in contact with. Tliere arc several species that infest the domestic fowl but it is not known that any of them are very prev- alent c>r very destructive in this country. Their mode of development is similar to that of tapeworms; thai is, it is necessary for the embryo to pass through an 59 iuteriuediate host, as a worm, before it can develop into a mature parasite in the body of the fowl. The symptoms occasiored by these jjarasites are similar to those produced by tapeworms but are of a less violent and serious character. The remedies and means of prevention are prac- tically the same. 3. ROUND WORMS— NEMATODES. The round worms are elongated and usually quite slender parasites, mostly of a whitisli color and are provided with a mouth and digestive canal. When present at all they are apt to exist in considerable num- bers, and sometimes occur in vast quantities. There is one form of round worms known as Trichosoma con- tortum, a little white worm from one-half to three- fourths of an inch long, that has been found beneath the mucous membrane lining the oesophagus and crop. Sometimes as many as thirty of these worms have been found in the oesophagus in a single bird. They inter- fere seriously with the passage of food through this tube, affect the digestion and apjjetite and cause wast- ing and \\eakness. At length, the oesophagus be- comes engorged with food, it cannot contract or pass its contents along and the animal dies within a few days. Some species of round worms collect in the intestine in great nun'bers, in fact, as many as five hundred have been removed from the body of a single fowl. By their presence they occasion a good deal of irritation of the digestive tract, intref ere with nutrition, cause diarrhoea and weaki.ess and death. Sometimes the disease caused by these parasites follows a long course anjl 60 does not terminate fatallv for a number of weeks or l)erbaps not at all. In other cases, death results very quickly. The ternciDation depends upon the strength of the fowl and the number and variety of the worms. If the worms are present in sufficient numbers to eo- tire occlude the intestine, death is i)roduced very quickly. Another species of round worm, Heterakis maculose, has occasiored great loss amo-ng birds. This worm is white, cylindrical and pointed at each end; the male is about an inch long and the female one and a quarter inches. Sometimes several hun- dren of them are found in the intestine of a sin- gle pigeon. Birds with round worms may be treated by administering the common pi u; worm, a, male ; B, female. remedy reoommeided by Baronio, consisting of equal parts of the root of male shield fern, tansy and savory, of whicli mixture one drachm is made into a tea with six ounces of water and this fluid is mixed with suffi- cient flour to form pills and these are administered to the infested fowls. Or, the powdered areca nut may be given in doses of from thirty to forty grains for chickens and fifteen grains for pigeons. The prevention of disease resulting from the pres- ence of the round worms may be accomi)lished by en- forcing the general regulations recommended above, in connection with the discussion of tapeworms. The frequent removal and the care of the maiiuie is very ijnportanl. A Round Worm of the Pigeon. Heterakis »iacw?o»a— Natural size. The 61 A. Those not caused hy parasites. 1. CATAHKH OF THE CROP. When, for any reason, (lie contents o-f the crop stagnate for an unusual length of time it mav undergo fermentation, just as food accumu- lated in any other warm, moist place would undergo fermen- tation, and this results in the production of a rather irritative com- pound which, acting for a more or less pro- longed period upon the lining membrane of the crop, produces a superfi- cial inflammation known as catarrh. The same result may occur when parasites are em- bedded in the lining membrane of the crop or when fowls eat irri- tant materials. This condition may be recognized by the ap- pearance of a swelling in front of the breast DiGKSTivE Apparatus of biros.

TJie appetite is entirely lost or becomes abnormal, the fowl is mopish, its feath- ers are rnffied and it may attemi)t to vomit. If the crop is preitsed upon forcibly, sour and o-lfensive smel- ling material may be expelled through the mouth. The cure of this condition is not difficult unless it has continued for such a long time that the fowl is considerably T\eakened. The irritant, fermenting or putrefying contents should be expelled by pressure from witl)'Out while the fowl is held with the head down. Then a small quantity of salicylic acid (two grains) dissolved in water should be administered for the purpose of checking further fermentatio-n or hydrochloric acid may be given in one drop doses di- luted with two teaspoonfuls of water. The fowl should be kept from food for a day or tvNo and usually this is all that the case requires. 2. OBSTRUCTION OF THE CROP. If a fowl has gorged itself with food that is ditlicult of digestion, such as old and dry grain or hard and in- digestible substances, as straw, wood, stones, etc., and this material remains in the crop for several hours the walls of the crop will become exhausted by the un- usaal distention and then the fowl is unable to remove the obstn.-ction in any way. The recognition of the condition is not difficult because there exists a large, firm, hard swelling in the region of the crop. T'j)on 63 feeling of it, the natiii-e of its eonteuts can frequently be determined. If it is not possible to remove the contents by pres- sure, as in the case above, and if it does not pass away naturally within a day, it becomes necessary to per- form an operation for the i)urp<>se of emptying tiie organ. To do this, the feathers should be removed by clipping them off with a pair of shears from a vertical line about half an inch wide alo-ng the most prominent portion of the crop. Then with a sharp, clean knife an incision about one inch long should be made through the skin and down to the obstructing mate- rial. This can then be removed with the handle of a spoon, or_with the finger, o^r with the loop of a hairpin. When the crop is thoroughly enipliid. its walls should be united by sewing them with, white silk. Care should be taken to avoid including anything besides the walls of the crop in the first seam. After this is perfectly ui'ited the other tissues and the skin may be drawn together with a second set of stitches. The sewing should be done neatly and the tissues should lict be dra^^ u together so that they pucker. The ends of the first set of stitches should be left long and al- lovN'ed to h£ing outside of the wound. In five or six days union will have taken place and the stiches can then be removed by cutting through them with a pair of sharp scissors and drawing them out. After this operation, the bird should be allo-wed no food for twenty -four hours, and only a small amount of water, to which a few grains of salicvlic acid have been added. 64 :}. SIMPLE INDIGESTION AND LOSS OF APPE TITE. These conditions result from such a variety of causes that it is rather difficult to classify them as a disease. Usually they are merely symptoms of dis- ease in different organs or oie('ps of m<'tal, etc.. are ])resent. tlicy should be removed by an operation similar to the oper 65 ation performed in impaction of the crop, provided they are in the upper or neck portion of the gullet. When the cause of loss of appetite is known the se- lection of an appropriate foi-m of treatment is a mat- ter of but little dimculty. If it is decided that the fowl cannot be cured it will be best in all cases to kill it at once so that it may be saved for food. If the dis- ease is allowed to jj;o on until serious changes take place it will not be safe to use the tlesh. It is well to begin treatment by giving two or three teaspoonfuls of castor oil to empty the bowels and re- move irritant substances. One of the best general remedies is hydrochloric acid. This substance is very strong and must be ad- ministered in very small quantities freely diluted with water. The dose for an adult fowl is from one to two drops given with at least a dessert spoonful of water. Pills of either black or red pepper, are in high repute among p'oultry keepers and are undoubtedly quite effi- cient in stimulating the secretion of digestive juices and in that way leading to restoration of appetite. Chopped onion or garlic in the food are also good. 1. IRRITATION OF THE DKIESTIVE CANAL AND DIARRHOEA. This subject has been considered in part in connec- tion with the condition produced by intestinal worms and with the subject above. Similar irritations of the membrane lining the digestive canal may be produced 5--I 66 by otlier foreig^i bodies in the intestine or, wluil amounts to the same thing, by indigestible or imper- fectly digested food that remains there for an unusual length of time. The first evidence of irritation of the digestive tract is loss of appetite and general depres- sion. This is quickly followed by diarrhoea, and the voidings are sometimes mixed with mucus or, in bad oases, with blood. When this symptom appears the fowl loses flesh very ra[>idly, becomes weak and soo-n dies. The first measure in the way of treatment is to place the bird in a warm dry place where it will not be an- noyed by its companions and supply it with small quantities of food that is easy of digestion. This should be given in a fresh state in clean troughs or vessels and all of the surroundings should be kept clean. If the diarrhoea is severe, cooked food should be preferred, such as boiled meal, rice or barley; oat meal is also good. Small pieces of, chocolate consti- tute a useful remedy for this condition in cage birds. Linseed meal is also good and the gelatinous substance that separates from linseed when it is boiled is of great value in diarrhoea. It is g(»od of itself, and it also furnishes an excellent medium for the administra- tion of other more active remedies. Opium can usually be relied upon to check this disease unless it has gone so far that no treatment will avail. Opium is best used in the form of the tincture, known as laudanum. Tlie dose is from five to ten drops. Tincture of catechu is very efficient and may be given in doses of five to twenty drops wMth n little water for each fowl, or foi- fiftv fowls, half ounce in meal. 67 5. CONSTIPATION, Constipation is the opposite of diarrhoea, but it is frecjuently produced by tlie same conditions. If para- sites obstruct the intestinal canal, of course nothing can pass and the result is constipation of a most ob- stinate form. Sometimes the intestine becomes un- usuall}' dry, particularly after a bird has been afflicted with diarrhoea for some time; then its coaitents accum- ulate in hard masses and form obstructions. These obstructions of dry intestinal contents may appear at any point of the canal but frequently develop close to the lower opening, in the diverticulum known as the cloaca. Constipated birds give evidence of the condition by uneasiness, loss of appetite, frequent, unsuccessful at- tempts and general depression. If the obstruction is in the lower part of the bowel the treatment consists in injecting small quantities of warm water b}' means of a rubber syringe, or water in which linseed has been boiled may be used for this purpose and should be pre- ferred in cases where there is considerable irritation. Sweet oil or glycerine may also be injected, all of which tend to soften and facilitate the removal of the impacted masses. When this treatment is applied to hens, great care should be exercised to prevent the in- troduction of tlie nO'Zzle of the syringe into the open- ing of the oviduct. Sometimes it is necessary to em- ploy a small blunt instrument, such as the handle of a small spoon to facilitate the removal of the faecal masses in this location. 68 Intern:! lly, castor oil is a valuable remedy. It should be j;iven in doses of two teaspooufuls; or, the eommon compound cathartic pill may be administered, ('alomel is also a good laxative ov purgative for fowls and is giveji in doses of from one-half to two grains mixed with sufficient butter to foam a pill. Small cage birds should receive a fragment of a cathartic pill, the size depebding upon the size of the patient. Epsom salts are good and safe; the dose for an adult fowl is one tablespoonfnl of a satui'att'd solution. ♦>. POISOMXC. Fowls may be poisoned by the same chemicals aud agencies tliat poison larger animals. Poisoning with Arsenic— One of the most frequent poisons is iuseiiic in one of its numerous forms. Arsenic is u.sed so freely on farms for the ])urpose of po'isoning potato bugs, wonns that infest tre^s, rats, etc., that it frequently liappens that it comes within the reach of poultry and poisons them. The symp- toms of arsenic poisoning are loss of appetite, great thirst, discharge of saliva from the mouth, attempts to vomit, anxiety, restlessness and diarrhoea. Before death the bird may evidence considerable pain, breathe with difficulty, tremble and it may have convulsions. After death, the examination of the digestive tract will show that it is considerably inflamed. It is red. full of blood and its contents are mixed with blood. The treatment to be employed when it is known that 69 fowls liavc been poisoned with arsenic is to administer the white of an agg every hour ov the thicic liquid in which flaxseed has been boiled. If possible, the chemi- cal antidote, iron sesquioxide or dialized iron, should be given. If there is much diarrhoea and pain tincture of opium in doses of five to ten drops is useful. Pow- dered chalk given in ^^■ater is also good. Poisoning with Salt. — Small quantities of salt are very beneficial for fowls but large quantities may cause serious illness or even death. From half an ounce to an ounce of salt is fatal for a chicken. This quan- tity will cause loss of appetite, great thirst, redness of the membranes lining the mouth and throat, pain and diarrhoea, and if the poisoned fowl is opened after death it will be found that the intestines are in a con- dition resembling that found when death results from arsenical poisoning, but usually the inflammation is not of quite such a severe type. Such substances as mackerel brine, beef pickle, etc., are even more pois- onous than pure salt and smaller quantities will pro- duce the same symptoms. Tlie treatment consists in the administration of the remedies recon.mended for arsenic poisoning, with the exception of the iron compounds. Poisoning ivitli Mould. — T\'hen fowls are permitted to eat food that has undergone decomposition or has become very mouldy they are sometimes poisoned. This subject has been referred to under the head of irritation of the digestive canal and diarrhot^a. 70 7. DROPSY. Tli€^ membiaiie liniu*;- Ihe abdomiual cavity »ome- times becomes intiamed as the result of external inju- ries or severe irritation of the intestinal canal or the penetration of a foreign body thro-ugh the intestinal wall. Sometimes this condition is caused by parasites. Usually' the disease is of a severe tj^pe and cannot be treated successfully. It may produce death within a very short time. But sometimes it follows a chronic course, causing prolonged illness, and in these cases. fluid usually collects in the abdominal cavity consti- tuting the c(indition known as ascites or abdominal dropsy. The evidence of this condition consists in an enlargement of the abdom.en ; it is distended in all di- rections but particularly downward and sometimes to such an extent that the lower part of the belly reaches the ground. It is hardly necessary to say that in these cases the fowl is spiritless and disinclined to moveabout actively; Avhen it is caught and the swelling is ex- amined by the touch it will be noticed that it is soft and that by pressing upon one side weaves can be felt on the other side indicating that it contains fluid. 8. JAUNDICE OK THE YELLOWS. When the action of the liver is interfered with the bile may not be poured out into the intestine in a nor- mal manner and its retention leads to a yellow disco! 71 oration of all parts of the body, shown especially about the comb, orifices of the nose and membrane liniuj^ the mouth and throiit. This condition is frequently produced by parasites but sometimes it results from too hijc^h feeding and too little exercise. In these lat- ter cases, a dose of ealo-mel should be administered; the food, which must be cut down in quantity, should be of a simple character and contain green substances, and the fowl should be allowed plenty of exercise. CHAPTER IV. DISEASES OF THE EGG-PRODUCING ORGANS. 1. PARASITES AND FOREIGN BODIES IN EGGS. The egg is produced as follows: the yolk develops in the ovary, which is a large conglomerate mass, the ap- pearance of which may be compared roughly to that of a bunch of grapes of different sizes. When the yolk reaches its full development in this organ, the mem- brane containing it breaks and it is discharged into the o-viduct. In passing through the oviduct it be- comes surrounded by albumin, known as the white of the egg. The development of the albumin requires about six hours. In the lower part of the oviduct, it remains for about twenty-four hours and during this time it becomes covered with a membrane and a shell. If foreign bodies, or parasites of any kind, are pres- ent in the oviduct, they may readily become incorpo- rated with the albumin and in that way become en- closed in the egg. There are a number of parasites of poultry that have been found enca]>sulated in this way. The imprisonment of parasites in the egg is not a very serious matter, however, because it occurs quite in (72) 73 frequently; but it is serious when the germs of decay are present in the oviduct and become imprisoned in the egg, because this leads to the early decomposition of the egg. The organism that may enter the egg in tins manner and produce decomposition are of several kinds, but as their effects are about the same it is not important to discuss them separately. They cause the yolk to become light in color and cloudy and cause the liberation of gas that is usually taken up by the fluid parts of the egg, but escapes when the shell is broken, and is of a most unpleasant odor. These germs do not get into the oviduct by passing into the fowl with its food, water or the air that it breathes, but enter through the cloaca, and are often introduced by the organs of the male during the act of copulation. This condition may be avoided by the enforcement of cleanliness in the poultry houses and poultry yards. Hens and cocks should never be al- lowed to go about with masses of fllth adhering to the feathers about the vent nor should they be compelled to roost in filthy places or walk about and scratch in masses of decaying and putrefying material. Cleanliness and disinfection enable the poulterer to avoid this infection of the egg. 2. MALFORMED PJGGS. One of the most frequent malformations of eggs is the so-called "double egg," the egg containing two yolks. Tliese eggs are usually of very largo size and develop when two yolks rtnuh maturity in the ovary at 74 the same time and are dischar <;ed into the oviduct to gether. Cases have been known in ^^hi(•h three yolks have been found in the same egg. Sometimes eggs of unusual shape are noticed; they are pear-shiij.ed, spherical, tlattened, pointed at each end or bent. Sometimes they contain projections at some point on the surface. All of these conditions result from accidental influeuces, and as a rule they do not recur. An important malformation, or rather lack of devel- opment, corsists in the production of eggs without shells or with soft shells. This condition usually re- sults from the fact that the hen which ])roduced the egg laid it before the shell had time to develop or that she was not supplied with the proper kind of nourish- ment, and therefore could not produce the lime salts necessary for the secretion of the shell.* The treatment in the latter case consists in giving fowls ground oyster shells, broken egg shells or ])ieces of ground bone. 3. EGG BOUND. Sometimes an egg becomes caught in the oviduct and cannot be expelled. K may be that this comes from the fact lliat Ihe egg is too large oi' that irritation or inilammation has caused a swelling that obstructs the passage, or that the cloaca is obstructed with a mass of faeces. In these cases, it is necessary to sup- *See Inflammation of the Oviduct. 75 \>ly assistance. If it is fouiul that \Uv cloaca is ob- structed, the faecal masses should be removed in the manner described under constipation. If the egj^ is large, or the passage small, the injection of oil or glycerine may enable the hen to expel it. If, however, it cannot be removed in this manner an attempt should be made to expel it by placing the hen upon her back and pressing above the egg through the abdominal walls and in that way forcing it out. If it cannot be removed in this way, the only alternative is to break it and remove tbe shell piece by piece. The fragments of shell should be removed with the finger or a pair of forceps. When the pieces of shell cannot be removed at once, sweet oil should be injected in order to- lu bricate the passages as freely as possible and facilitate the removal of the sharj), broken pieces. 4. INFLAMMATION OF THE OVIDUCT. The oviduct sometimes becomes inflamed as the re- sult of the manipulations necessary to overcome the condition of egg-bo-und, and sometimes it becomes in- llamed from causes that are not understood. When this inflammation exists, the hen makes movements as though she were attempting to lay an egg, is very uneasy, rubs the posterior portion of the body along the ground, and in these ways indicates irritation of that part. Sometimes the first symptoms of beginning infhimmation of the oviduct is the production of eggs with soft shells. This condition has l>een found not 5-1 70 only aiDoiiLj chickens, but also among ducks, geese and turkeys. The treat IE ent of this disease is not very satisfac- tory. Tt consists in placing the bird in a quite place where it will not be annoyed and, in acute cases, in- jecting a weak solution of tannic acid (1 part to 100). to which a small quantity of chlorate of potash (2 or 3 parts to 100) has been added. This tluid should be made warm before it is injected, and should be admin- istered carefully and in small quantities. The best syringe for this purpose is a soft rubber bulb supplied with a hard rubber nozzle. Laxatives, such as castor oil or calomel should be administered in sufficient quantities to keep the bowel loose. The food should be non-stimulating, and given in small quantities. 5. PROLAPSUS OF THE OVIDUCT. As a result of great straining to expel an unusually large egg, the oviduct may be turned inside out and project from the body of the hen. It can then be seen as a red swelling protruding from the rear part of the body, the hen becomes very uneasy, and it is impossi- ble for her to lay eggs while in this condition. In ex- amining these cases, particular attention should be paid to the color of the inverted membrane. If it is very dark, and of a purplish or bluish tinge, treatment should not be attem]»ted. for this indicates that gan- grene is about to begin, and in these cases the fowls can not be saved, so that it is better to destroy theni 77 while still fit for food. If the membrane is red. it should be washed off with warm water, covered with a thin coating of vaseline and pushed back very care- fully. If it is expelled again it should be again re- turned and a small piece of ice placed in the opening. This will usually cause the parts to contract to such an extent that they will not fall out. From the be- ginning of the treatment, the hen. must be kept in a quiet place and allowed very little food. CHAPTER V. DISEASES OF THE BRAIN AND EYE. 1. CONGESTION OF THE BRAIN. Congestion of the brain may be caused by extreme excitement, by blows on the head or sunstroke. It is characterized by staggering, stupor, unusual move- ments, such as v.alking backwards or walking in a cir- cle, unusual and irregular movements with the wings and feet and tv^isting the head backwards or to the side. Sometimes the bird will fall on its side and make peculiar movements with its feet and wings, as though attempting to run or fly. Tlie treatment consists in keeping the animal per- fectly quiet in a dark place, the administration of laxa- tives, such as two teaspoonfuls of castor oil or one and one-half grain doses of calomel, and the application of cold cloths or ice to the head. EPILEPSY. Epil('|»sv is uot a veiv ((niiiiKm (lis<';is(' jiiiKnig pout try, but still it is met with fium time to tiiiic and (78) 70 aiuuiij; all vaiiclics of barnyard I'owls. It is charader- ized by the occasioual oceur-rpnte of tils which do not terminate faljilly, disappear after a time and leave the fowl in a normal condition. During the fit, the fowl will make beating movements with its wings, its legs will draw up and it will fall down, sometimes turn over on its back, or it may stand upright with its legs apart, head turned backwaid and the mouth and eyes open- ing and closing spasmodically. Epilepsy is sometimes caused by intestinal ])arasites, and is cured by the re- moval of these ^orms. It is claimed that bromide of potash given in quantities of a few grains each day in the drinking water is of value in these cases, but it is not probable that treatment will prove to be at all profitable. 3. FEATHER EATING. This habit is classed among the affections of the ner- vous system because if it is not nervous disease it is such an overpo\^enng habit that it can scarcely be dis- tinguished from the disease. Where this habit is prevalent in a poultry yard, the fowls present a most untidy appearance, the feathers about the neck and upper part of the breast are plucked out. and sometimes they are partially removed from other parts of the body. If the flo-ck is watched for a little while it will be noticed that the birds pluck the feathers fr(»m each othei'. Tliis habit usuall.v starts with one fowl and sjtrcads by foi-ce of examj)le to Ihe others. .so ill oidfi' U) pievfut it, a lovvi tliat is iioticod pluck iug- feathers should be at once removed from the liock before the others litive had time to learn the habit. If it is not dtsirable that the bird should hv killed, several methods for preventinn' the continuation of the habit are recommended. The best and most humane is to tile awav the bill in front and on the sides so that it will not close tightly, but when shut leaves a space of about one-tenth of an inch. This will prevent the bird from grasping the feather with sufficient force to re- move it, but will not interfere with eating. Another remedy that has been suggested is to place a piece of wire through the mouth as a bit and carry the upper end of wirt through a liole that has been punctured in the oomb. Tliis has the effect of preventing the fowl from closing the beak tightly, and therefore from palling out the feathers, but is rather a cruel proced- ure and cannot be recommended. In all cases, fo^wls inflicted in this way should be allowed a large yard, so that they may have plenty of exercise. 4. EGG EATING. This is another habit that spreads from fowl to fowl similar to the above. If eggs are allowed to remain too long" in the nests so that they become broken, or if soft shell eggs are produced by any of the hens in the tlO'Ck some of the fowls may get into the way of eating" them, and the habit once started spreads from bird to bird until in some cases it becomes almost impossible lo secni'c anv eggs at all. 81 The Ireatnieiil in tbt'se should be to lenuivc the bird that spreads the habit as sooii as il is delected, or if this is not done, and the habit becomes well established, a special form of nest should be used which permits the egg to roll out and escape from the reach of the hen as soon ns it is deposited. o. TUMORS OF THE EYELIDS. Sometimes wart growths appear upon the eyelids and they may become large enough to interfere with the vision or by pressure upon the eye balls destro-y the sight. Not only warty growths appear in this region, but also other tumors of a variety of kinds. When it is evident that they are becoming large enough to l)e- corae harmful, they should be snipped oMinting the surface with tincture t)f iodine and removing the cause by making the perches wide and smooth or lowering them, as may bo required. 86 •2. HUMBLEFOOT. The causes that produce cunis will, if of au espe- cially severe type, cause deep and serious bruises of the joints of the feet and legs. These bruises are followed by swellings of the joints, the parts become very ten- der and sore so that it becomes diBicult for the bird to walk. The piincipal joint of the foot may become very much enlarged so that the deformity can be seen from a considerable distance. A close examination will show that the swelling is very painful to pressure and is sometimes feverish and soft. If it does not termin- ate within a short time, germs from the injury may enter the bones or pass to joints further up the leg and lead to swelling, great soreness and sometimes to abscess formation or gangrene. The causes of bumblefoot should be avoided and the treatment of the -condition consists in applying flaxseed poultices, by tying a bag of cheesecloth containing the poultice around the foot, or applying an ointment made of cieolin and vaseline (one part to forty). If the swelling becomes soft, so that it is evident that it contains pus it should be opened by making au incision into it with a sliarp knife and its contents should then be syringed out with a solu- tion of creolin and water (one part to fifty). In the more severe cases, accompanied by the formation of large abscesses of grangrene, no treatment can be suc- cessful. Scmi cases of buniTilefo-ot develop to a cer- tain extent and then continue in the same condition for a long time, leaving the fowl wilh ;i rhronic de- formity of the f<-et. Tliese old cases nic best frcntcd by painliiig the enlarged joints willi iddiuc or by ()]m'ii irig file swellings and applying iodine to I heir inleiior 87 3. GOUT. Fowls of the heavy breeds, when kept in a liigli con- dition and allowed but little exercise, may develop a disease that is practically identical with gout in man. It usually develops rather slowly, beginning as a some- what indefiiiite lameness that might be mistaken for rheumatism. But shortly the joints of the feet and legs, and sometimes of the wings as well, swell, be- come painful to pressure, the bird becomes disinclined to move; later, little tunio-rs, that are rather hard, ap- pear about the affected joints and still later the skin covering these enlargements becomes dry, brittle and breaks, exposing a yellow or grayish crumbling, chalky mass which is composed principally of uric acid and its salts. Sometimes, the toes dry up, lose their life and fall of. The general spirits of the fowl are, of course, depressed, because it is difficult for it to get around. It becomes feverish, loses its appetite, wastes away and toward the end develops a diarrhoea that hastens death. Treatment of gout consists in removing the enlarge- ments by scraping them off with a blunt instrument or cutting them away with a knife, and, internally, bicar- bonate O'f sode should be administered. This can be supplied by adding it to the drinking water in quanti- ties of about a ter.spoonful to the pint. 8S 4. FREEZING The feet, coiubs and wtiltles of fowls exposed during very cold weather are frequently frozen. Usually but little can be done after the injury has taken place un less the condition is detected early, at which time it may be possible to save the frozen parts by remo'ving the fpost with applications of snow or cold water, annointing the frozen parts with cosmoline g>v camphor- ated oil and placing the fowl in a reasonably, though no-t \er\, warm place, and keeping the frozen parts moistened with the applications mentioned. CHAPTER VII. DISEASES OF THE BONES. 1. RICKETS. Rickets is a disease of the bones that prevents their becoming hard and stift as they should, thus allowing them to bend and become deformed under the weight of the fowl. The bones that are most frequently sub- ject to deformity in cases of rickets are those of the legs and the breast bone because these carry the most weight. Rickets usually results from improper feed- ing. A growing fowl should not only have food to make flesh but also to make bone, and unless this is supplied in sufficient quantity and in an available form, the imperfectly nourished bones develop the con dition above described. The treatment consists in giving sufficient food of a proper sort, such as grains of all kinds, ground bone, ground shells, wallplaster from old buildings, broken egg shells, etc. A composition in high repute among ihe poailterers of England is Parrish's chemical food. Phosphate of lime, which is the princi]>al and mosr valaable ir.gredient of Parrish's chemical food, can Itr administered in doses of two oi- three grains |)cr day to each young chick that is noticr('ced('(l by 94 .1 ihoiimgh ck'j;i.sinji of the droppings. The yards should be spriidvled wilh lime, tlic feeding place should be scrupulously cleansed and disinfected, and the water sujiply should be looked to carefully, in order to avoid possible impurities or coutaniinat ion. The fowls that die should be cremated or deeply buried at a dis- tance fr(nu the poultry grounds. Tlie individual l)atients need not be de- sitroyiMl. as is sometimes done, because it is fre- quently possible to save them by means of very sim- ple treatment. It is impor- tant to place them in warm, dry (luarters, and feed nu- tritious, attractive food. Douglass mixture, referred to on page 38, is useful. The diphtheritic patches should be removed by scraping lightly witli a blunt metal or wooden instrument, or by rubbing them otf with a swab made by Avrapping a snmll pledget of cot- ton about the end of a toothpick. After they are removed, the raw surface thus exposed should be treated with an antiseptic, for the purpose of destroying the disease germs that remain. One of the best ;i]'i>lications for thi.s j)nrp(>se is a 10 per cent. solution of nitriite of silver, to be applied cautiously and in small quantities, with a camel's hair brush. (ir. a 2 j)er cent, solution of creolin or carbolic acid I h i m 1 m 1 m The Hoof of the Mouth of a Fowl, showing Diphtheritic Patches. 95 may he used. A solution of corrosive siiblimnle (1 part to J, 000 of water) is also sufficient, but must be used with gieat care. Iwersen recommendg petroleum in this disease and advises that a drop of this substance shall be placed in the nasal passage of the diseased fowl, and that the diseased membranes be treated with light applications applied with a small brush. If the nose is stopped up, peroxide of h\'drogeu, diluted with an equal amount of water, may be injected with a glass and rubber medicine dropper. If the dropper has a bent point, the medicine may be squirted into the back of the nose through the openings in the roof of the mouth. Roup or diphtheria may be prevented by avoiding unsanitary conditions, by enforcing cleanliness, disin- fecting frequently and preventing the introduction of foreign fowls into the flock until they have been kept isolated long enough to make sure that they are healthy. Cases have been reported from time to time in which it lias been claimed that diphtheria of fowls has been conveyed to people and vice versa. Recent investiga- tions, however, indicate that this disease in man and birds is caused by different organisms, and that the probability of tracsmission is not very great. With reference to this matter. Dr. V. A. Moore writes as follows:* "Altho-ugh the number of reported cases of the transmission of diphtheria to the human species and vk-e versa is small in comparison with the extent of the disease in poultry, the evidence that such a transmission is possible is quite sufficient to discour- age the careless handling of diseased fowls. It is quite a common practice, usually in the rural districts. ♦Bulletin No. 8, V. S. Depiartmpnt of Agriculture, 1S9.T. 96 to bring sick (.liiciceiis into the house for treatment where the children of tlie household are allowed lo fondle them al will. It is not improbable that when this disease is tt-orouj^hly investigated the number of cases of direct infection from this source will be found to be much larger than is at present supposed. Until such invesligaticns are satisfactorily completed the in- discriminate handling of diphtheritic fowls, especially by children, and the exposure of fowls to tJie infection of diphtheria in the human species whereby they may become carriers of the virus, should be strenuously avoided." 2. FOWL CHOLERA. The desigr-ation fowl cholera includes several in- fectious diseases of poultry, none of which have been thoroughly studied in this country during recent years. The fowl cholera that occurs in France and Germany is very well understood, but its symptoms do not agree fully with those of the various diseases known as fowl cholei-a in this country. The Bureau of Animal In- dustry in Washington has made some investigations of outbreaks of fatal contagious diseases among chick- ens and pigeons but the work is not yet completed. So far as it has gone, it indicates that one of the af- fecrions known as fo.wl cliolera is caused by a rod- shaped bacillus that is exceedingly resistant to ex- tremes of tempei-atui'c, and can probably live in ])ro- tected places for a long period.* ♦Bulletin No. S, U. S. Departmont of Asrirultuie, 1S9.'). 97 The syiDptcmfci of .Uucrieuii fowl eholeia were first (lesciibt'd by Di. tSalmou iu 1S80. 'I'iicv iiicliule the voidiug of faeces ot w liich the part that is normally white is yellow. The white part of tlie faeces is ex- creted by the kidneys, and the yellow discoloi'atiou of this excreraeut is usually the first indication of dis- ease. 'Shoi-tly thereafter the droppings become thin and fluid, they are voided frequently and envelop by a layer of tlin mucous. The fowl becomes depressed, it stands still or assumes a sitting posture, goes into a sunny, warm place if possible. The plumage be- comes ruffled, the head is drawn down, the comb be- comes pale and bloodless, and the appetite is depressed O'r lost. The depression and torpidity of the fowl in- creases until it seems to become unconscious and can- not be aroused by objects that usually frighten it. The bird becomes thin and weak and sometimes passes into a stupor and dies. In other cases, it may have convul- sions prior to death. The symptoms of the European fowl cholera, which may also occur in this country, although it has never been proven definitely, are in many respects similar to the above. In many cases, the disease runs such a vecj short course that no evidence of illness is dis- covered until the bird tumbles over in convulsions and dies. Somxetimes, the co-urse. of the disease is so rapid that more than half of a large floclv of apparently healthy chickens will die during a single night. Usually, however, the disease lasts from one to three days, and is evidenced by loss of appetite, depression, ruffling of the feathers, hanging wings, inclination to get away from the flock, high temperatur(\ discharge of mucous from the mouth, diarrhoea, thin faeces, that are at first slightly yellowish, but later on greenish and 7-1 98 haviiijj;' an olTensive odor; ij;reat tliirst, hlnisli disco-lora tion of the comb, and doath either in a stupor or pre- ceded In- c(>i'Vulsion.s. Alter death, the disscrliou of the bird reveals niiiueidiis i"d spots on the internal organs and especially on the inteslinos. Tiie lungs are congested, .led, full of blood; (he liver is full of blood and somewhat enlarged, and the blood itself is dark and thick. The intestines sometimes contain a red mass of clotted bloo-d. Another disease that is usually included with fowl cholera is a form of infectious enteritis of chickens, which consists in an inthimmation of the bowels that is of a very severe type, and causes death witliin one or two days after tlie beginning o-f the attack. The lirst symptom is diarrhoea, tliere is loss of appetite and de- pression, but the torpor is not so profound as in the disease described above. MoFadyean has recently described an outbreak of disease among turkeys that was characterized by an inflammatioi of the lungs and pericardium. The symptoms were general stiffness of the neck and limbs, hanging of the wings and tail, roughness of the feathers, ditlficult breathing, discliarge of frothy mucous from the mouth, diarrhoea, with thin, whitish or yel- low faeces and death. In this outbreak, a germ was found that was in many respects similar to the germ of fowl cholera, but presented points of difference that were suffici( ntly well marked to enable him to classify it as another organism. Eqizootic dysentery has been discovered among chickens and ducks and reported upon by veterinarians in a number of places. The disease begins as a diarrhoea, usvially attacking young chickens first. There is depression, chilliness, ruffling of the plumage, 99 lo.ss of appetite, j2;i'aduiilly becuiniui; more iuteii.sc uiilil the animal dies, during the second week of the attack. All of the above conditions are popularly known as fowl cholera, and, moreover, the term as commonly used, undoubtedly includes a number of other diseases that are not contagious at all. When fowls die in large nun bers it is usually said that the disease affect- ing them was fowl cholera, although it may have been produced by mismanagement of almost any kind. The treatment of individual fowls afflicted with such a highly contagious disease as true fowl cholera is not to be recommended, because in the first place, so long as the infected fowl remains around, there is danger that its poisonciis products may be carried to healthy birds. Secondly, there is little chance of curing it and it is hardly worth while to try. The important point in this connectio-n is the pre- vention of disease, and fowl cholera can usually be pre- vented by preventing the introduction of fowls suffering from it or that come from infected localities. If the dis- ease is once introduced, the most stringent measures should be enforced as regards cleanliness, disinfection and the total destruction of the carcasses of the dead birds. The birds that are still healthy should be re- moved from the flock and placed in a wholesome local- ity. The droppings from the diseased fowls should be burned or thoroughly disinfected by mixing with a ten per cent, solution of sulphuric acid or with a quantity of lime equal in amount to the manure. Th(^ building should be disinfected by cleaning it very thoroughly, flushing the Hoor with a saturated solution of copperas and spraying the interior with a 5 per cent, solution of carbolic arid followed by white-washing. Tf the pens and inns can 1)0 abandoned for a year and grass lUU j;T()V\n ill tlu'iii, this is the best plan, but if it is not pos- sible to do this they should be cleaned vvitli as great thorO'Ughntss as possible and slacked lime scattered ovei* the surface of the earth, which should be plowed. It should be remembered that the germs of fowl- cholera may be carried in the feathers, so that a per- fectly healthy fowl, coming from a diseased flock, may carry the disease to another flock a long distance away. These germs may also be carried on the shoes and clothing of persons; by vermin, as rats or mice, or they may become attached to light objects, such as leaves, and be carried long distances by the wind. If the dis- ease exists among the fowls alc'ng the water course, those lo^^er doA\n the stream may receive the germs with their water supj)ly. So, whenever this disease prevails in a locality, one cannot guard his fowls too careful Iv. :i. HLA(MvHKAI)— INFECTIOUS INTERO HEPA TITIS OF TURKEYS. The disease of turkeys po|)ular known as blackhead, has prevailed for a long time in the New England states and particularly in Rhode Island. Attention was called to it some few years ago by Mr. Samuel Cushnian, an officer of the Agricultural Ex])erinient Station of Rliode Island, but all of our recent informa- tion in regard to bhu'khead results from the investi- gations of Drs. Theobald Smith and V. A. Moore.* The disease is called ''blackhead" because in same of the turkevs afflicted with it, the comb and head become *T^ulletin No. 1. Civf-nlar No. 5, Bureau nf .Animal Industry, U. S. Department of .Asrioulture. 101 dark. The desigiicitioii is not a good one, however, be- cause this discoloration of the liead may come from other causes than this particuhir disease, and some- times in this disease the head does not become darl^. As yet, a good popular, descriptive name lias not been suggestd. Infectious entero-hepatitis is caused by protozoa, minute animal parasites so small and simple that they can scarcely be distinguished from some members of the vegetable kingdom. These gain access to the di- gestive tract of turkeys and enter the caeca, which are two prolonged pouches springing from the union of the small and large intes- tines. Within the caeca, the protozoa of this disease irritate the mucous mem- brane and cause it to be- come thickened and ulcer- ated. The caeca also be- come distended and some- times extraordinarily large. The protozorinci|>al featurcfs revc^alcd l».v a post inoi'tem exaiiiiiiatiou. Thv syiupluins are lather iii- deliiiite because the disease does not follow a regular course, so that a slightly affected turkey may present certain symptoms, while one in a more advanced stage of the disease may present entirely different symp- toms, that may be so different from the first that no connection betvAeen the cases would be suspected by an ordinary observer. It has been noticed by those who have investigated this disease, that turkeys fre- quently appear to recover from it; this is, after having been afflicted, sometimes quite seriously, they pick up in condition thereafter and apparently recover, but a post mortem examination of these fowls will show dis- tinct evidence of the disease. The walls of the caecum are still thickened, the spots in the liver remain, and a mi croscopical examination of the contents of the caecum reveal the living parasite of the disease, so that these ap parently recovered birds continue as sources of infec tion and can convey the dis ease to other fowls. ^'onng turkeys are most C.4!:cA OF Turkey Showing Ef- fect OF Protozoan Disease.

W'heu it is severe, they lose condition, develop diarrhoea, become thin, weak, ragged-looking-, their heads sometimes become dark, and they gradually die in an emaciated, exhausted con- dition. The disease can be recognized positively after death by discovering the conditiQns described above. Blackhead has been discovered among turkeys in eastern New York, and altho-ugh its presence has not been demonstrated positively among the turkeys of Pennsylvania, it is quite pos- sible that it exists here and some outbreaks of disease that have been described closely resemble blackhead. Our knowledge of this dis- ease is so recent that as yet it is only possible to experi ment with remedies with a view to curing the affection. Dr. Smith suggests the use of quinine and it may be that salicylate of soda, creoliu or calomel will prove ad- vantageous, but as yet the use of any drug is purely ex- perimental. It has been shown by Dr. Moore's exeperiments that the parasite of the disease exists in the droppings from afflicted fov^ls, and that it may be transferred di- rectly to healthy birds by keeping them where these droppings have been allowed to accumulate. The mal- ady has also been pro'duced in healthy turkeys by feeding the diseased organs of its victims.

The roci-stin^ place should be thoroughly cleansed, droppings should be collected and disinfected and the entire locality should be disinfected as thoroughly as possible by spraying with carbolic acid solution, saturating the Moors and earth with saturated solutions of copperas and covering the soil with lime. Then, if turkey breed- ing is to be contiriued, fresh stock should be purchased from regions where the disease does not exist cr tur- keys should be hatched under hens and in this way the nucleus of a new and sound tloek may be acquired. 4. TUliERCULOSIS. Tuberculosis, or consumption, is a very commo-n dis ease among people and among several species o-f our domestic animals, particularly cattle and swine. It is also found, although comparatively rarely, among other species of the domestic animals. In some places fowls are frequently found that are afflicted with this disease. For a long time it was thought it might have been acquired thi-ough eating the expectorations of tuberculous animals or man, or feeding upon tuber- culous organs of slaughtered animals, but recent in- vestigations have made it pi-actically certain that tu- berculosis of fowls is not the same disease as tuber- 1 1)5 cuiosis of tlie hig'lit'i- aiiinial«, mid altluMi^li these are similai- it is caused by a soniewliat dili'eieut germ, and' it is not probable that it is ever acquired from the higher animals nor that the higher auimals can acquire tuberculosis from fowls. The principal symptoms o-f tuberculosis are those of a lingering illness that grad ually becomes more severe. Sometimes, tubercles ap pear as hard and horny or as soft and cheesy swellings on the skin or about the joints. There is wasting, the comb and the membranes of the head become pale, the strength of the fowl is gradualh' lost and finally it dies, after having shrunken to a mere mass of bones, skin and feathers. After death, little white or yellow tubercles which contain cheesy matter may be found in the liver and spleen. About half of the fatal cases of tuberculosis in birds show tubercles, which appear as rather dense round masses, in the walls of intestine. They may also be found in some cases in the peritoneum, the membrane lining the abdominal cavity, and in the lungs. Many of the birds in Zo-ological Gardens die of tuberculosis, and it is very common among cage birds. A number of cases in parrots have been seen at the Veterinary Hospital of the University of Penn- sylvania. Tuberculosis of ])arrC'ts differs somewhat from that of chickens, in that it may be caused by a germ identical with that causing tuberculosis of man, and may be derived from or transmitted to people. So that tuberculous parrots are a menace to human health. There is no cure for tuberculosis, and the most effi cient means of {)reventing it r-onsists in killing and burniiii:' fovls that nia\' Itc sntTci-ini; with it .hkI tlinr km; (tu.nlily (lisiiiftM-linj; llir iMciiiiscs prcviniislv r. Moore, who found tliat a rather chionic wasting disease was })roduced by a germ that in some respects resembled th(; germ that causes hog cholera. "Going light" might be defined in many cases as a chronic, wasting disease of pigeons, that is due to a cause that is rji-kcown, but which is probably of an infectious nature. In some O'f the outbrealvS, the dis- ease runs a much moie rapid course than in others, and causes death witliin a few days. In other cases, its course is quite prolonged and the bird sometimes recovers. If treatment is employed it should consist in i:he administratJon of general tonics, such as qui- nine, in one grain doses twice a day; cod liver oil, one- half teaspoonful, 3 or 4 times daily; reduced iron in the food. Warm, well ventilated, comfortable surround ings. and noui'ishing and attractive food must be jtro vid^^d. The pig<'(in loft slionld be thoroughly r-leaiiscd ]{)7 iiiid disinfected in reference to this affection, and if pigeon fanciers will notify the State Veterinarian when ontbreaivs appear they will be investigated with a view of discovering the exact cause and the measures to be taken to cure or pievent it. 108 DESCRIPTION OP OPPOSITE PLATE.

The name Fisher, which appears after names of different birds of prey, indicates that the illustration has been repro- duced from Dr. A.K. Fisher's report, Bulletin No. 3, United States Department of Agriculture, Washing-ton, D. C, entitled "The Hawks and Owls of the United States," published in 1893. This document, prepared by Dr. Fisher, one of the foremost Ornithologists in the United States, under the direction of Dr. C. Hart Merriam, Chief of the Biological Division of the Na- tional Agricultural Department, deals fully with the birds of prey in their relation to agriculture. It is, without doubt, the best work on this subject that has been published. The name of Ward, which follows names of different animals, signifies that the specimen from which the illustration was reproduced was furnished from the valuable collection of Messrs. H. A. and F. A. Ward, of Rochester, New Tork, pro- prietors of one of the largest and best equipped natural science establishments in the country. The name Audubon, placed after a few name.? of birds and mammals, shows that the illustration has been copied, with some minor changes, from Audubon's "Birds of North America, or the "Quadrupeds of North America" by Audubon and Bach- man. The remainder of the illustrations have been made especially for this work from specimens. CHAPTER III. American Hawk Owl (adult)— Ward. Bald Eagle (adult)— Fisher. Bald Eagle (young) — Ward.

THE VALUE OF PENNSYLV ANJ AS POULTRY. It is estimated tLat tlie value ot poultiy of all kiudf and the eggs produced in Pennsylvania last year was about $22,000,000. By these figures it will be seen that the industry is one of great importance; in faci it is one of the most important branches of agricul ture. as statistics show that "the annual poultry pro ducts of the United States are equal in value to the wheat crop." THE VALUE OF FOWLS AND EGOS IN THE UNITKD STATES. I'ennsylvania, one of the leading Stalts in tlu- Union in the production of poultry, has, it is stated, about 275,000 persons engaged, on a more or less extensive- scale, in the poultry raising business. My esteemed colleague. Dr. Pearson, says, basing his statement on a recent estimate published in the .American ,\grirul tuiist, that "According to a recent estimate of the American Agricul- turt.st. base<1 f'n the las! oPiisus and on an extensive inqniri . i-n H) the number of fowls In the United States is about 383.000,000; these produce 1,141,000,000 dozen eggs each year, and the value of both amounts to $313,000,000.00. There are in this State 15,374,000 fowls of all sorts; turkeys, geese, ducks and chickens, valued at $S, 236, 000 and these produce 68,818,000 dozen of eggs each year worth, at 20 cents per dozen, $13,763,600, making a total value for poultry of about $22,000,000"— Pearson. Tlie loss to poultry, both old and young, through dis ease is considerable. Dr. Pearson observes that, at a very conservative estimate, one-tenth of the poultry of this Commonwealth is, each year, carried away by disease. However, as the various diseases, with besr remedies for the same, of domestic fowls, are carefully discussed in Part I of this document, I deem it unnec pssary to make further reference to disp'ases which arc such a hindrance to success in poultry-raising, and which, sometimes, destroy, if not promptly and intelli- gently treated, the entire population of the poultry yard. . LOSS IN PENNSYLVANIA FROM PREDATORY ANIMALS. When I prepared the preliminary report (Part II., Bulletin No. 17, Dept. of Agriculture, issued in Nov., 189G). entitled ''Some Furred and Feathered Enemies of Domestic Fowls." I was unable, because of insuffi- cient data, (which, with a number of books and valu- able papers belonging to the Commissioner of Forestry and myself, had been carelessly thrown away by some workmen who were making alterations about a closet where our property was stored), to give even an ap- proximately correct estimate of the loss to poultry an- nually incurred through the depredations of predatory animals. To give an accurate estimate of the money lost through depredations of wild animals to the poul try interest would, of course, be impossible, as probably few individuals in our State, who are the possessors 3 of a flock of barn yard fowls, keep any record of the loss of poultry or eggs which are destroyed in the course of a year by any of the wild animals which it is well established subsist in part, at least, on young or old poultry and eggs. However, through the aid ot circulars and postal cards making inquiries as to prob- able money loss annually sustained from the visits of foxes, minks, weasels, wildcats, rats, certain species of hawks and owls, crows, etc., it is learned that the yearly loss in Pennsylvania is probably about 1750,000. This sum is a large one, and, perhaps, to a person who has given little thought and attention to the matter. it will appear to be excessive. Such, however, judging from the answers received at this office, does not ap- pear to be the case, as may be seen by consulting the replies of farmers and jjoulterers, which are given in full on succeeding pages of this work. Well informed gentlemen, who are thoroughly familiar with the poul- try business, and the losses effected by the depredations of the various animals commonly included under the caption "Enemies of Domestic Fowls," claim that the average loss yearly to each individual farmer and poultry-raiser throughout Pennsylvania, through the depredations of the many species of birds, mammals etc., which kill poultry or destroy their eggs, is fully five dollars. If there are, as it is claimed, 275,000 poultry raisers in this State and they each sustain an annual loss of five dollars, the aggregate loss would be $1,375,000. No doubt, there are hundreds, yes. thousands, of farmers and other persons who are engaged in rearing poultry who, individually, and perhaps yearly, suffer a much greater loss than five dollars, as can readily be seen by consulting reports made to this Department and printed in ditteient cliapters which appear on succeeding i)ages. Such cases, however, allhougli quite numerous could not, with any degree of fairness, be used exelusivelv iu makiiij* up estimates. It is also worthy of particular iioic to bear in mind thai when proper care is taken to protect fowls from their furred and feathered foes, the loss annually can be very materially lessened. F'armers and other poultry raisers \y]io make no efforts to have their poultry safely housed at night time, naturally sustain losses from the attacks of nocturnal marauders, such as foxes, minks, weasels, opossums, rats, 1he Great Horned Owl, ete. These losses, frequently, could easily be avoided if proper precautionary measures were adopted. Thos.- who reside in sections near large woods, mountaiuou.^ districts, streams and ponds often suffer very great losses from predatory animals, unless particular pains are taken to guard the fowls and exterminate the sly pilferers. I have known a single pair of Cooper's hawks, in the spring when they had a nest of younji in a woods about half a mile from a friend's barnyard and chicken coojjs. to destroy in one week over fifty young chickens. A pair of Sharp-shinned Hawks, when compelled to provide food for a nest of young, have been knoAsn to visit a single farm and kill, on an average, five or six young chickens daily, foi- a period of a week or ten days. Goshawks will also sometimes visit farm houses fo»' several days in succession and kill poultry, both old and young. Usually, however, the Goshawk, when breed insr, keeijis in the woods, w^liere he finds an abundance of food, an important item of which, unfortunately. \* that noble game bird the Ruffed Grouse. The Duck Hawk, a suninicr i-esidfut, in a few l<»caliti<'s of this stale, iilsu, at times, destroys some poiilti-y, particii larly ducks. TRAP OR SHOUT THK TROUBLESOME HAWKS. VVheu the poult ly raiser discovers that a liawk or hawks of auy species are paying regular visits to his poultry yard, he should, at once, begin an investigation and learn, if possible, where the nest or nests of sucli unwelcome visitors are located. When this informa- tion is obtained the bold feathered depreaators can usually be shot or ti-apped at their nests. When this is done the nests and young should be destroyed as no liumane person would want to leave the young hawks to die of starvation, as is. so commonly done by the heartless and money loving plume-hunters, who have praetieally depopulated the southern states of the beautiful herons. The hat-bird and plume-hunter, ii. the pursuit of his nefarious business — one, kind reaaer, which has been made possible because our mothers, sisters and sweet-hearts, seem determined to decorate tlieir headgear with showy feathers — visits the breed- ing places of the herons, egrets, etc., and shoots the old birds from the nests. The clamorous young, by thou- sands, in some large nesting places, have been left by the heartless wretches, to die by the tortures of starva- tion, as the carcasses of their parents, denuded of the showy feathers, lay rotting on the ground. KEEP YOUR EYE ON THE CROW. Fretiuently it happens that a pair of crows will set up house-keeping in a woods in the neighborhood of the farmer's chicken coops, and if left undisturbed they will pick up a good many young chickens, and steal all the eggs they can find. .\ visit to the woods will irenprallv enable vou to discovei- the home of these « black-coated poultry thieves, which, of course, can be destroyed, together with the old birds. Should you fail to find the nest of the crow, you can easily dispose of him by drilling an egg, insert a little strychnine in the hole, and phice the deadly bait in a nest he has been robbing or in a conspicuous place where he will be likely to^see it as he comes spying around after the chirping offspring of the fussy and ever solicitous old hen, who, often penned up in a coop or fastened by a long cord and one leg to a peg in the ground, is ever on guard to shield her family of youngsters. HERONS. BLACKBIRDS AND JAYS. Several species of the heron tribe occasionally de- vour the young of ducks and other birds which are found about streams, ponds and marshy ground fre- quented by these long-legged waders. Of late years, however, the herons and bitterns have so greatly de- creased in numbers, that the damage they do by de- stroying the young of ducks or other kinds of birds is trifling. Crow blackbirds are abundant in this State and if these birds were as much given to preying on young chickens and destroying the eggs of domestic fowls, us they are to devouring the young and eggs of different species of small insectivorous birds, they would no doubt cause considerable loss annually. Fortunately, however, the habit of feeding on the eggs of domestic fowls and their young seems to be confined, so far as my observation goes, to individual blackbirds, "black- sheep," so to speak, which appear here and there in different communities. Blackbirds which have acquired an appetite for the eggs and young of domestic fowls '•an oasilv be desi roved, but when this is done it would not, iu my opinion, be a wise procedure for the farmer to place all blackbirds under ban, because of the mis- deeds of a few individuals which may have developed a taste for forbidden food. Although blackbirds, un- doubtedly, destro3' the homes of a good many small wild birds, the fact seems pretty well established that these birds, during the summer season, are much more beneficial than harmful to the fanner. Nine times out of ten an investigation will show that when crows and blackbirds visit the corn fields, when the young corn blades are an inch or two above the ground, that they are there, not to destroy the corn, as many suppose, but to feed on the cut-worms which are often so abun- dant as to ruin entire fields and render a replanting necessary. THE JAYS. The "Scrub'' or Florida Jay (Apelocoma floridana) is greatly detested in some parts of Florida where they are plentiful. The enniit}' to these birds, known locally as "Scrub Jays" because they are found in a thick under-growth, arises from the fact that they destroy the eggs of chickens. They come about build- ings and destroy the eggs, and they will also, I am inloinied, sometimes attack and kill young fowls as well as different species of wild birds which they can master. In attacking the young of chickens or other fowls, the jays, it is asserted, always strike at the head, and with a few vigorous strokes of their bills, soon per- forate the tender coverings of the brain. Usually when not disturbed the jay will eat the brain matter, pick out the eyes, and leave the rest of the fowl undis tnrbed. The habit of destroying eggs and poultry must De iiitli*'!- ('oiiiiiKiii vvilli tlu' Species under rtmsuieratiou. as I found, in 1885, at several localities which were visited in Orauj^e and other counties along the St. Johns river, that special efforts were made by the residents to destroy these birds, on account of the reasons narrated in the preceding paragraphs. The Florida Rlne Jay, a local race technically styled ( Cyanocitta cristaia florincolaj, is a little smaller and has less white on tips of secondary and tail feathers than the Blue Jay (Cyanocitta cristata J. It is also in had repute with Florida farmers who assort that ii sncks the eggs of chickens. THE JAY KILLED BIRDS AND SQUIRREL. Referring to the Blue Jay, Audubon wrote: "It robsevery nest it can find, sucks the eggs like the crow, or tears to pieces and devours the young birds. A friend once wounded a grouse (Bonasa umbellus), and marked the direction which it followed, but had not proceeded two hundred yards in pursuit, when he heard something fluttering in the bushes, and found his bird belabored by two blue jays who were picking out its eyes. The same person once put a flying squirrel into the cage of one of these birds, merely to preserve it for one night; but on looking into the cage about 11 o'clock next day he found the mammal partly eaten. A blue jay at Charleston destroyed all the birds of an aviary. One after another had been killed, and the rats were supposed to have been the culprits, but no crevice could be seen large enough to admit one. Then the mice were accused, and war was waged against them, but still the birds continued to be killed, flrst the smaller, then the larger, until the Key west pigeons, when it was discovered that a jay which had been raised in the aviary was the depredator. He was taken out and placed in a cage, with a quantity of corn, flour and several small birds which he had .lust killed. The birds he soon devoured, but the flour he would not condescend to eat, and refusing every other kind of food, soon died. En the north It is fond of ripe chestnuts, and in visiting the trees Is sure to select the choicest. When these fall it attacks the beech nuts, acorns, peas, apples and green corn. In Lon- isana they are so abundant as to prove a nuisance to the tHiTTiers. picking the newly planted corn, the poas and sweet potatoes, attacking every fruit tree, and even dt-sliuyiriK ihc eggs of pigeons and domestic fowls. The planters are in tht- habit of occasionally soaking some corn in a solution of ar- senic, and scattering the seeds over the ground, in conse- quence of which many jays are found dead about the fields and gardens." JAYS ARE NOTORIOUS NEST ROBBERS. Although Blue Jays have decreased greatly in uiam sections of the country since that able naturalist. Audubon,, penned the paragraphs last quoted, they have not by any means deviated, as far as can be learned, from the thieving practices of their loquacious an , (restors. The Blue Jays of the present day have had trans mitted to them the same carnivorous tastes which yearw of observation in the woods and chosen haunts of thp jays, prompted the gifted Audubon to write so posi tively about their pernicious habits. Every farmer's boy who is familiar with the gar I'ulous and inquisitive jays, is well aware that they an- especially fond of eggs and young birds. Whenever an opportunity offers, whether it be in woodland, orchard, garden or bramble, these blue-coated robbers put forth all their energies to steal the eggs and young of their neighbors — birds which consume, during their summer sojourn with us, myriads of noxious insects. These numerous forms of insect-life, which are de- voured by the beneficial birds whose homes are so frequently despoiled by the robber-jays, would, if not kept in check by their natural enemies, bring about :i destruction of trees and other plant-life which oannoT be computed. SAVE THE BIRDS The absolute necessity of protecting in every wav pnssiMo the bonoficinl or the insect -eating birds oannni 10 be too strongly urged upon all classes of our people. Farmers and fruit-growers, particularly, should make especial efforts to encourage the presence of beneficial birds on their premises. The Pennsylvania I?oard of Game Commissioners, assisted by the members of the State Sportsmen's Association, have prepared, with great care, a game bill, which is, at present writing, in the hands of the Legislature. If this measure becomes a law, it will afford protection to insectivorous birds which has never before been given in this State. If the section, as originally framed, of thisl bill, which deals with "wild song and insectivorous birds,", passes both branches of the General Assembly and re- ceives executive approval, the days of the hat-bird killer and the commercial bird-egg hunter will be numbered, as they most assuredly should be. The millinery taxidermists, the bird-egg-collecting fad, so common with school boys, have in the last ten or fifteen years caused an enormous depletion of bird- life. The millinery trade requires bright-plumaged birds to satisfy its tender-hearted, charming and lovable cus- tomers. 20,000 BIRDS IN FOUR YEARS. To fill the orders received from the millinery es- tablishments, taxidermists have scoured the woods, or- chards, mountains and fields in search of victims. In this manner immense numbers of showy species such as orioles, tanagers, warblers, rose-breasted grosbeaks, cardinals, indigo buntings, jays, bobolinks, wood- peckers, snow birds, larks, etc., have been slaughtered. Some few years ago I met a taxidermist in one of our large cities, wiio, with the aid of one assistant (a taxidermist) and sovpral m^n and hovs. wliom he fm- 11 plojed to shoot birds during migrations and in the early summer, cleared over -fH,500 iu less thau one year by the sale of mounted birds for hats and bonnets. His expenditures, he said, were about $1,500 in the ten months he was actively engaged in the business. He fiold the birds at prices ranging from one dollar and fifty cents per dozen, for small-sized, dull-plumaged birds, (song sparrows, hair-birds, juncos, English spar rows, oven birds, etc.). to five, six, eight and ten dollars per dozen, for male scarlet tanagers, red-winged black- birds, bobolinks, rose-breasted grosbeaks, indigo birds and bright-plumaged warblers such as the Black- burnian, Kentucky, Yellow and Magnolia. This same individual also, some years before, or when the craze of decorating woman's headgear with birds first begait. in one season obtained from the coast of New Jersey 1.100 (erns, chiefly the Lesser Tern {Sterna antillarum) and gulls, for which he gave the gunners fifteen anO twenty-five cents apiece, and then stuffed and sold them for hats at twelve and fifteen dollars per dozen. During the four years which this man engaged in supplying birds to milliners he collected, mostly in IVunsylvania and New Jersey, at least 20,000 skins. AVhy produce here these statistics of the hnt-bird taxidermist? They are uivt'ii .simply to call attention of the farmers of Pennsylvania, for whose especial benefit the legislators directed this report should be prepared, to one of the chief causes which has been in active opera- tion for the past ten or fifteen years to destroy birds, many of which rank among the first of all natural agencies which the Wise Creator has placed in our midst to keei) in check ravenous insect hosts, that, if tincheckcfl. would sooti 1;iy onr crops to waste. A PROTEST FROM THE BAT STATE. This wanton and senseless destruction of bird-life is not by any means restricted to Tennsylvania. In Massachusetts, where about three-quarters of a million of dollars has been expended during the past four or five years to repress a single insect foe — the Gipsy Moth — hat-bird hunters, professional snarers, or "pot- hunters," and the ubiquitious small boy with an old musket, are playing havoc with the feathered popula- tion, many of which, if unmolested, and allowed to follow their natural inclinations would undoubtedly be a potent factor to aid in keeping in check the voracious Gypsy Moth. Regarding the agencies which are rapid- ly bringing about the extermination of the feathered tribes in the Bay State, I take the following paragraphs from the annual report of the Massachusetts Game Commission, for 1896: "Reports from our deputies and other reliable sources show a still further decrease in our game birds. Especially is this true in the eastern and middle sections of the State. This de- pletion is due to over shooting and that most destructive of all weapons, the snare. In some sections snares have been set by the thousands, completely clearing out the ruffed grouse, and, if thisi nefarious work is not stopped, this finest of game birds will be entirely destroyed. It seems useless for the State to expend money for the protection of game unless this work can be suppressed. All snaring should be prohibited, under severe penalty of fine or imprisonment, or both, at the discre- tion of the court. The time in which game can be killed should be shortened, and the open season for all game be the same. Unless some decided action is taken, there will be in the near future no game in our woods and fields. SAVE OUR SONG BIRDS. "As to song and insectivorous birds, the laws should be more vigorously enforced. Now, any boy who ran raise ^1.^0 to buy an old Springfield musket, considers himself privileged to take any wild thing he sees for a target. This, togethei- with thp fashinn nf demrating ladies' hats with skins and wings of 13 birds, has led to the depletion of insectivorous birds to such a degree that scarcely a crop of any kind can be raised without spraying with poison to kill the insects which were formerly kept in check by the birds. The penalty for this destruction of the balance of nature is everywhere apparent, and the hor- ticulturist and farmer are heavily taxed for want of foresight in protecting their own interests. "If the destruction of these birds cannot be otherwise re- strained, let the law for their protection extend to 'the posses- sion of their skins or any part thereof,' except for scientific purposes." TILE SNARER IN EVIDENCE IN PENNSYLVANIA. During recent years it appears, from reports which reach this office from various sections of the State, that the snaring of birds has been carried on to a great extent. This murderous nifC-thod is engaged in prin- cipally by a class of foreigners who are apparently thoroughly acquainted with all the devices of the poachers of the Old World. Rufifed grouse, in some regions of the State, have been almost entirely extir- pated through this villainous practice. Although Huffed Grouse, undoubtedly, suffer the most from snares, this method of capture is, unfortunately, by no means confined to these game birds. These death dealing and cunningly hidden snares have, on several occasions, been discovert d in swamps and meadow lands, places where Woodcock and Wilson's or English snipe are known to frequent. Men who make a busi- ness of hunting meat or bird's skins for the market, catch numbers of small song and bright-plumaged birds by the use of birdlime and snares, the latter art- fully placed about the nests. A member of our State Game Commission in the early part of November, 1896, visited the market stalls of one of onr large cities and examined forty Ruffed 14 Grouse; eight hnd been shot, the remainder had beeu snared. BIRD BUTCHERY IN PIKE COUNTY. The following- article from the pen of the Milford Pa., correspondent of the New York Sun, published Novem- ber 15, 189G, will give some idea of the snarer's wort in Pike county, and the same condition of affairs exists in other counties of Pennsylvania: •Hunters in Pike county complain of the scarcity of game in certain sections where in years gone by it was very abundant, and they attribute the scarcity to poachers. It is true that large bags of birds have been captured in the present season, and these lead to the stories that game is plentiful. "This, however, is not the case," said the veteran guide and hunter, Charley Mott, of this borough. "Nine out of every ten of the supposed large bags of birds are the results of from 400 to 600 snares, covering the choicest hunting grounds for a radius of five miles or more from the home, or temporary stop- ping place, of the poacher. The shipments to New York city usually represent the fruits of the set guns of two or more of the poachers, and are the result of from four days to one week with the deadly devices. "One week ago a shipper of birds was seen travelling in the woods, not with dog and gun but with a two-bushel sack fastened over his shoulder and directing his course toward the grounds that a few years ago were the most famous to be found anywhere for that noble bird, the Ruffed Grouse. What manner of cover or grounds productive of birds can long stand 3u:h wanton and i'bgal destruction and continue to g ve pleas- ure to the sportsman? "For many years," continued Mr. Mott, "I found great pleas- ure and fine sport shooting on the grounds referred to, but the wonderful scarcity of birds of late and the discovery as to the cause of this scarcity have led me and sporting friends to abandon the section as a shooting resort." Mr. Mott is of the opinion that if measures are not taken soon to protect young grouse from the summer wnndmck shooters and to break up the marketing of snared birds, grouse will be virtually extinct in Pike county in the near future. 15 BIRD-EXTERMINATORS IN NEBRASKA AND GEORGIA. According to the New York Sun: "J. H. Den and three com- panions are reported to have Icilled 700 wild geese and duclis in the northern part of Nebraslta on a recent hunting trip. Seven hundred such birds would weigh not much, if any less, than a ton. H. J. Lamar, Jr., and a party of hunters went to Leesburg, Ga., dove hunting. The amount of game that they killed makes one think of the wild pigeons away back in the fifties. The party killed 8,000 of the birds. The American Field says of this killing that 'such fiendish work by men who claim to be sportsmen makes our blood boil with indignation. • • • Their Inhuman greed was unsportsmanlike." If this kind of work is allowed to go on for a few years we will have no game of any kind to shoot. PASSING OF FAMILIAR BIRDS. The great value of insectivorous birds cannot be overestimated. The fact is evident to all who have given any attention to the subject that if the wasteful, cruel and useless slaughter of birds is not soon checked numerous species will be obliterated from regions where in former years they were abundant. About twenty years ago wild pigeons bred in immense num- bers in certain sections of Pennsylvania; but they are now gone. Why have they left? The reason is, pri- marily, because they were so relentlessly pursued by netters and market hunters, and, secondly, on account of the destruction of the primitive forests where they resorted to breed. Fifteen years ago the beneficial and euewily dressed Red-headed Woodpecker was one of the most common birds to be met with on a day's outing in the rural districts. Now, it is rather unusual to see one of these birds in sections where, in my boyhood days, they were abundant. What has been largely instrumental in bringing about this change? Why, the love of pecuniary gain Mi aud (he saiiilv of the lair sex liave iui3i)iiec] ihe aiili navy taxideiuiisls to shi lighter, Jear after year, these fiolitsoiiie teuuiits of hollow trees; beautiful defeuce- less cieatures, whose livelihood was earned maiuly b\ destrojiug insects aud larvae destructive of forest, shade and fruit trees. It is true this bird sometimes \ isited the corn field or cherry tree, but the damage done on such occasions was trivial when compared with (he good he did in the orchard or forest. Men, we are told, particularly a class of miserly fel lows who have been married for some years, are prone to comment in no favorable way about the cost of lovely woman's head dress. So far as the writer is (concerned he believes it is every man's duty, and if he has the right kind of a wife, I know it would be a l>leasure, to assist, so far as he is financially able, in obtaining the requisite head attornment for his better half. I do not believe, however, that any man should be asked or expected to encourage the decoration of his wife's head with feathers which have been torn from the bodie^s of mute and lifeless birds. The chief objection I have to offer to this hatandbonnet business is the persistence which so many ladies have for deco rating their pretty heads with beneficial birds' skins. i)o away with such ornamentations, double, if you de .sire, the amounts paid for feathers, add an extra quan rity of artificial flowers, vines and iridescent ribbons, but spare, I beg of you, the harmless and defenceless fiiembers of "the summer's tuneful host." THK PKNNSYI>VANIA AUDUBON SOCIKTV It is certainly fortunate in many ways that the Pennsylvania Audubon Society, with headquarters in Phiadelphia, has lately been largely instrumental in 17 arousiug iu differeut quarters of the State a stroufj desire to protect souj^ birds. The officers of this or- gauizatioD include a number of the best-know citi- zens of Philadelphia. They are: President. WITHER STONE. Vice Presidents. MISS FRANCES E. BENNETT. MRS. A. T. COPE, MRS. S.

This organization of ladies and gentlemen jjublish 3-rT 18 and distribute gratuitously, a very interesting and val- uable little pamphlet, which can be obtained by ad- dressing the secretary, Mrs. Edward Robins, 114 South 21st St., Philadelphia, Pa. The good work of the Audubon Society has struck a popular vein as is evidenced by the fact that within a i)eriod of five montlis, from about the firs^t of -lanuarv of the present year, over fourteen hundred ladies and gentlemen have placed their names on the membership rolls of the society. The earnest and commendable efforts of this society cannot fail to do a vast amount of good, and all classes of our citizens should aid in this new field of labor, which, if carried to a successful end, will be of in- calculable value to this and future generations. No class of our citizens would derive greater benefits from the protection of birds than the farmers and fruit-growers. To successfully protect birds in this State it is very essential to secure the hearty co-operation of the farmers and the farmers' boys. Unfortunately, however, in some sections of Penn- sylvania, different species of birds and mammals are regarded with disfavor because of a lack of knowledge of their beneficent services. When these mistaken opinions are corrected and the praiseworthy aim of the Audubon Society is thoroughly understood, I am satis- fied that the farmers of this Commonwealth will ex- tend such assistance that the professional hat-bird hunter, snarer, and meat-hunter, will be forced to aban- don their nefarious trade. With a view of giving a brief idea of the. magni- tude of insect depredations throughout the United States, a few paragraphs are added under the sub-head "Insect Ravages." Such records should certainlv have 19 influence to aid in staying the hand which is tm) often imjustl}- raised against birds ;iud other wild auiuiais which are friends rather than enemies of the human race. INSECT RAVAGES. The plum crop in many regions of Pennsylvania Is almost a total failure because of the ravages of the curculio and the fungus known as black knot. Yet, it orchardists would heed advice and follow the recom mendations of scientific men who give special atteu tion to the life histories of insects, fungi and birds, plum culture could, no doubt, be condnet
