 ESTABLISHMENT AND GROWTH OF THE FISH COMMISSION. 
 
 In 1871 Congress passed a joint resolution authorizing the President 
 to appoint a Commissioner of Fish and Fisheries, whose duties were thus 
 defined : " To prosecute investigations on the subject (of the diminution 
 of valuable fishes) with the view of ascertaining whether any and what 
 diminution in the number of food- fishes of the coast and the lakes of the 
 United States has taken place ; and, if so, to what causes the same is 
 due; and also whether any and what protection, prohibitory or precau- 
 tionary measures should be adopted in the premises, and to report upon 
 the same to Congress." 
 
 Subsequent legislation from time to time extended the duties of the 
 Commissioner, and finally led to the formation of the Fish Commission. 
 The propagation and distribution of food-fishes, which soon became the 
 most important woi'k of the Commission, was inaugurated under authority 
 of an act of Congress in 1872. A study of the methods and statistics of 
 the fisheries was specifically authorized in 1879 and has since been 
 regularly carried on. The biological and economic inquiries provided for 
 in the original act have been continued uninterruptedly and have greatly 
 increased in scope and magnitude. 
 
 By act of Congress approved February 14, 1903, the Fish Commission 
 was made a bureau of the new Department of Commerce and Labor, and 
 on June 30, 1903, it terminated its independent existence. 
 
 PRESENT FUNCTIONS AND ORGANIZATION. 
 
 The work of the Commission, for convenience of administration, is 
 conducted under three main heads : 
 
 (1) The multiplication of useful food animals and the stocking of 
 waters therewith. 
 
 (2) The investigation of the interior, coastal, and off-shore watei's of 
 the United States, with reference to biological and physical problems, 
 including a study of the life histories of food-fishes and other economic 
 animals, as well as the life histories of the animals and plants upon which 
 they feed or upon which their food is nourished. 
 
 (3) The investigation of the' present and past methods of the fisheries 
 in their relation to the catch and the preservation of the supply, and the 
 
4 UNITED STATES FISH COMMISSION. 
 
 collection of statistics of the commercial fisheries of the United States, 
 including persons engaged ; vessels, apparatus, and capital employed, 
 and quantity and value of the products taken. 
 
 Since 1871 the Commission has published an annual report in which 
 its various operations are referred to in detail, and, in addition, many 
 important articles pertaining to fish-culture, fisheries, and biological 
 investigations in the United States and foreign countries have appeared 
 as appendices. In 1880 the publication of the Bulletin of the United 
 States Fish Commission was begun, and volumes have since appeared 
 yearly. This volume contains matter of the same general character as 
 the appendix to the annual reports. 
 
 WHAT THE FISH COMMISSION IS DOING. 
 
 The Commission has acquired a world-wide reputation on account of 
 the character, magnitude, and results of its operations, and has achieved 
 marked success in many lines of economic and scientific work. 
 
 In 1903 the work of propagating food-fishes and stocking public waters 
 therewith was more successful than in any previous year. The number 
 of hatcheries operated was 46, and the number of eggs and fish distrib- 
 uted exceeded one and a quarter billions. The species of fishes distrib- 
 uted numbered about 50, and included the leading food and game fishes 
 of the lakes and rivers as well as many important salt-water forms. The 
 lobster, most valuable of our crustaceans, is hatched at two stations in 
 Massachusetts, and a special lobster hatchery has recently been estab- 
 lished on the coast of Maine. 
 
 Up to the present time the Commission's output of food-fishes has 
 exceeded 13 billions, and very important effects have followed the culti- 
 vation of fishes on such an immense scale. Depleted waters have been 
 restocked, the supply of certain species has been maintained or increased 
 in spite of very extensive fishing,' and fishes have been introduced into 
 new waters where they have proved of great economic value. 
 
 The recent biological investigations have covered a wide range and 
 have been addressed to some of the most vital matters affecting the fish- 
 ing industry and the artificial propagation of fishes. The oyster, the 
 leading water product, has deservedly received much attention ; and prog- 
 ress has been made in the important experiments having for their object 
 the fattening of oysters by artificially increasing their natural food. The 
 lobster, the blue crab, the diamond-back terrapin, the Atlantic and Pacific 
 salmons, the commercial sponges of Florida, and numerous other fishery 
 objects have been studied in their biologico-economic aspects. The 
 aquatic resources of the Hawaiian Islands and the salmon industry of 
 Alaska have recently been exhaustively considered. 
 
 Statistical canvasses of the entire fishing industry of the Middle Atlan- 
 tic, South Atlantic, and Gulf States, were carried on in 1903, and a num- 
 ber of statistical inquiries were addressed to special States and Territo- 
 ries, as Alaska and Porto Rico.

 STATUS OF THE UNITED STATES FISH COMMISSION. 
 
 The act of Congress approved March 1, 1901, providing for the parti- 
 cipation of the government departments and bureaus in the Louisiana 
 Purchase Exposition, mentioned specifically the United States Commis- 
 sion of Fish and Fisheries. The Commissioner appointed Mr. W. de C. 
 Ravenel, assistant in charge of fish-culture, as the representative of the 
 Commission on the government board of management ; and detailed 
 other employees from time to time to assist in the preparation, installa- 
 tion, and care of the exhibit. 
 
 Owing to the peculiar nature of the exhibit, involving an extensive 
 fresh and salt-water aquarium and also the use of water for other pur- 
 poses, it was adjudged desirable by the government board to provide an 
 independent building for the Fish Commission exhibit. 
 
 THE BUILDING AND THE AQUARIUM. 
 
 The government fisheries building, located 175 feet west of the main 
 government building, is 136 feet square, with a central open court 74 feet 
 square. The exterior of the structure is in classical Grecian style, while 
 the interior resembles a Pompeian atrium. The facades are ornamented 
 by Ionic columns, 36 feet high and 4 feet in diameter, engaged for three- 
 fourths of their height but free above and supporting an open loggia. 
 Alternating with the columns are fountains playing into large basins rest- 
 ing on the backs of turtles, and over each fountain is a group of four 
 generic names of American fishes, marine shore fishes being represented 
 on the east and north walls, pelagic and deep-sea fishes on the south wall, 
 and fresh-water fishes on the west wall. 
 
 In the open court is displayed the general exhibit of the Fish Commis- 
 sion, which occupies 5,476 square feet. In the center is a pool, 24 feet 
 square, open to the sky and surrounded by 12 Doric columns, 3 feet 10 
 inches in diameter, which support the roof. In addition to the conven- 
 tional ornaments appropriate to such a building, shells, dolphins, and 
 fish-forms have been freely introduced. 
 
 The aquarium comprises 40 tanks, which line the walls of the building, 
 and covers 13,000 square feet. The tanks are of various sizes : two are 
 12 feet long, 6 feet high and 7 feet wide ; four are 5 feet long, 3^ feet 
 high and 5 feet wide ; five are 3 feet long, 2 feet high and 2 feet wide, and 
 twenty-nine are 7 feet long, 3<jr feet high and 6 feet wide. The aquarium 
 is separated from the case exhibit and the square central court, which it 
 surrounds, by corridors 15 feet 9 inches wide ; these are in semi-darkness, 
 while the tanks are lighted only from the rear, so that the animals are 
 plainly visible and the general effect is very pleasing. Opposite the tanks 
 the walls of the corridors are covered with a continuous series of plate- 
 glass mirrors, which reflect the tanks and give the effect of increased size. 
 
 The aquarium is constructed in the I'omanesque style, in keeping with 
 the remainder of the interior. Across the ceiling of the corridors are 
 beams supported on pilasters on either side of the tanks and forming 
 
UNITED STATES FISH COMMISSION. 
 
 deep panels. Over each tank is a large circular window for ventilating 
 purposes, and lower down there is a square window in which is fitted a 
 comprehensive label of translucent paper lighted from behind. 
 
 The machinery room, occupying 1,728 square feet, is under the main 
 floor ; in it are the electric pumps, filters, motors, air-pump, refrigerating 
 machine, etc. Under the portico at the north entrance reservoir tanks 
 for salt water and fresh water, with a capacity of 40,000 and 32,000 gal- 
 lons respectively, are located.

 Fish-culture. • i 
 
 Under this head are arranged those articles which illustrate the work 
 of the Commission in the artificial propagation of food-fishes and the 
 stocking of fresh and salt water therewith. The exhibit includes full- 
 sized samples or models of apparatus and appliances used in collecting 
 eggs, in hatching fresh-water and marine fishes, and in distributing fishes; 
 also photographs, drawings and charts showing the methods of the work 
 and some of the practical results of fish-culture. 
 
LOUISIANA PURCHASE EXPOSITION. 7 
 
 Throughout the Exposition there will be demonstrations of practical 
 fish-hatching on a scale of considerable magnitude, many millions of eggs 
 being utilized. Troughs are provided for the hatching of the eggs of the 
 quinnat and other salmons of the Pacific coast, grayling, brook trout, 
 rainbow trout, black-spotted trout, steelhead trout and other species 
 having heavy eggs ; tables are equipped with automatic jars and other 
 jars for hatching eggs of the shad, pike perch and white-fish; and auto- 
 matic tidal boxes are installed for the incubation of the floating eggs of 
 the cod and other marine species. 
 
 A working model of the Cail fish-way, as improved by Mr. Hector von 
 Bayer, engineer and architect of the Commission, shows the construction 
 of the best ladder for enabling fish to surmount obstacles in streams. 
 
 A series of very effective mutascope pictures illustrates some of the 
 phases of practical work in fish-culture addressed to various kinds of fishes. 
 
 In collaboration with the Rhode Island fish commission there is 
 exhibited an exquisite model of a floating nursery for lobsters. 
 
 A model of a special railway car, such as is used by the Commission in 
 transporting live fishes in all parts of the country, is shown ; and on a 
 railway siding near the Fish Commission building, one of the cars, 
 employed in bringing fishes for the aquarium, may be inspected from 
 time to time during the Exposition. 
 
 Scientific Inquiry. 
 
 The Division of Scientific Inquiry of the Commission is charged with 
 the investigation of the various natural phenomena which bear upon 
 the fisheries. These inquiries embrace researches upon the geographical 
 distribution of fishes and other species of aquatic animals, their migra- 
 tions and relative abundance under varying conditions, their food, 
 enemies, parasites and diseases, as well as the study of those facts of 
 embryology, growth, and habits which are essential to the development 
 of rational methods of fish culture. 
 
 All branches of marine and fresh- water biology, as well as the physical 
 and chemical qualities of the water, have more or less direct bearing 
 upon the fisheries, and a. wide scope must therefore be given to the 
 investigation. Besides having the co-operation of other branches of the 
 public service, the small permanent scientific force of the Commission is 
 supplemented, during the summer months especially, by the employ- 
 ment of trained investigators from various institutions of learning. 
 
 This exhibit is designed to illustrate, as far'as practicable, the character 
 of the equipment maintained for the prosecution of these varied and 
 widely distributed investigations, the methods employed, and sOme of 
 the results attained. It is not possible to follow out this design with 
 any degree of completeness, as much of the work lends itself not at all 
 to the purposes of exhibition. Owing to lack of space, it is not even 
 possible to show all of the apparatus used, much of which would be of 
 little interest save in actual service. It has been deemed advisable, there- 
 fore, to exclude from the exhibit all such instruments and apparatus as 
 are common to other branches of research, and which, like microscopes, 
 
O UNITED STATES FISH COMMISSION. 
 
 microtomes, chemical apparatus, etc., are familiar objects to a large part 
 of the public. The space allotted to this branch has been utilized for 
 the display of apparatus used in making littoral and deep-sea investiga- 
 tions, much of which has been invented or modified by persons in the 
 employ of the Commission. 
 
 Besides a number of smaller vessels, the Commission has two sea-goiug 
 steamers, the Albatross and the Fish Hawk, na^d^s~ol-jyJiie.h.-_-are 
 shown-onihe central aisles. The Fish Hawk has varied duties, for in 
 addition to carrying on marine biological investigations, she is also used 
 during certain portions of the year as a hatchery for shad and other 
 valuable marine animals. The maintenance of the shad fishery of the 
 Delaware is largely due to her efficiency. The Albatross is designed 
 especially for the investigation of the off-shore fisheries, and has had 
 more service in deep-sea investigations than any other vessel in the 
 world. She is an able sea-boat, and her equipment is especially complete 
 and her laboratory facilities ample and convenient. 
 
 Adjoining the model of the Fish Hawk is a Tanner sounding machine 
 with its equipment of instruments for physical research. This type of 
 machine is used on both the Albatross and the Fish Hawk for depths 
 not exceeding 500 fathoms, and in addition the former is equipped with 
 a steam-power sounding engine for use in the greater depths of the sea. 
 
 Most of the types of collecting apparatus used by the Commission are 
 shown in the exhibit running diagonally across the section. The large 
 net on_the floor is a beam trawl, the most efficient net used for obtaining 
 specimens from the ocean floor. The round iron hoops are not part of 
 the net, but merely supports to exhibit it in the position which it assumes 
 when in use. A net of this general type has been used by the Albatross 
 in a depth of 4,200 fathoms (4| miles). Suspended from the ceiling 
 above the beam trawl are types of apparatus used for collecting specimens 
 from the surface, bottom or intermediate depths. The tangle is used 
 where the bottom is too rocky for trawls or dredges, and it catches speci- 
 mens by entangling them in its hemp swabs. The Chester dredge and 
 the Smith dredge are two variants of the same type, and are designed to 
 rake out and catch burrowing worms, mollusca, Crustacea, etc. The ordi- 
 nary dredges are used from small boats or from ships where the use of 
 the beam trawl is impracticable. When brought on deck the contents of 
 these various appliances are emptied into a series of sieves, where they 
 are washed to remove the mud and sand, sorted by the naturalists, and 
 preserved in suitable reagents for future study. 
 
 The large surface tow-net, which is lined with silk bolting cloth, is used 
 to collect the swarming pelagic life of the sea. Though often individ- 
 ually insignificant, minute, or microscopic, the aggregate cf this surface 
 life is enormous and important, and it supplies, directly or indirectly, food 
 for most aquatic animals. 
 
 The intermediate tow-nets, two types of which are exhibited, are used 
 when it is desired to determine definitely the depth from which speci- 
 mens are obtained. They are sent down vertically, towed horizontally at 
 
LOUISIANA PUKCHASE EXPOSITION. \) 
 
 the required depth, and then closed by a mechanism actuated by a mes- 
 senger or weight slid down the tow rope. No specimens are taken, there- 
 fore, either during descent or ascent, and the investigator is furnished 
 with important information concerning the vertical distribution of the 
 forms which he studies. The Commission has recently adopted for field 
 use a chest containing these various appliances in miniature adapted for 
 use from small boats and launches. A chest containing a beam trawl, 
 dredge, tangles, tow-net, sieves, etc., is exhibited. 
 
 Seines, gill-nets, scoop-nets, scrape-nets, and other appliances used in 
 shore collecting are variously shown in the section, and collecting tanks 
 and chests for the preservation and transportation of specimens are also 
 exhibited in juxtaposition with the other apparatus. 
 
 The sponge fishery, which is confined to the State of Florida, is one 
 of the most important of the local fisheries of the United States, and has 
 recently been the subject of scientific inquiry and experiment. The 
 natural beds have been depleted and some of the results of the Commis- 
 sion's experiments in artificial sponge culture are shown. 
 
 The oyster is by far the most important single product of our fisheries, 
 and three cases are devoted to an exhibit to illustrate the anatomy, growth, 
 local and accidental variations, enemies and other facts in its life history. 
 In a section of the adjoining wall case some of the methods of oyster cul- 
 ture are shown. 
 
 Most of the space in the wall cases is devoted to the display of an 
 exhibit prepared by the Rhode Island Commission of Inland Fisheries to 
 illustrate the results of researches into the life history of various shell- 
 fishes conducted by that commission in collaboration with the United 
 States Fish Commission. These preparations show the growth of the 
 soft clam, scallop, oyster, lobster and starfish, bringing out important 
 facts in their life histories. Lobster development is also especially illus- 
 trated by the microscopic preparations on an adjoining table. The star- 
 fish is one of the most destructive enemies of the oyster, and the other 
 species are all economically important as food. Certain important facts 
 not before known were brought out by these investigations, upon which 
 have been based practical methods of clam and lobster culture and other 
 suggestions of economic value. 
 
 Fishes, and especially those in captivity in ponds and artificial bodies 
 of water, are susceptible to various diseases which sometimes produce 
 serious epidemics. These are constantly under investigation by the Com- 
 mission, and a few of them, with the organisms by which they are caused, 
 are shown in a special case. 
 
 The exposition at St. Louis, though world-wide in its scope, is especi- 
 ally in relation to the Mississippi Valley, and the charts on the walls above 
 the cases in the scientific section illustrate the geographical distribution 
 of the more important food-fishes of that region. 
 
 Methods and /Statistics of the Fisheries. 
 The division of the Commission concerned with the methods and statis- 
 tics of the United States fisheries conducts inquiries through a regular 
 
10 UNITED STATES PISH COMMISSION. 
 
 corps of agents for the purpose of showing the extent and condition of 
 the fishing industry, the chief apparatus and methods employed, and the 
 changes taking place in our fisheries from year to year. The most com- 
 plete and accurate statistics are gathered and published from time to 
 time for gratuitous distribution. Preliminary condensed one-sheet bulle- 
 tins are issued, and later the detailed tables, with appropriate text, are 
 printed in the regular reports of the Commission. 
 
 The commercial fisheries of the United States, as determined by the 
 Commission, represent an investment of about $76,000,000, give employ- 
 ment to over 215,000 people, and are worth $50,000,000 or more to the 
 fishermen annually. Fish and other water animals contribute largely to 
 the food supply of the country. These are placed on the market in a 
 large variety of conditions ; although mostly sold fresh, many are salted, 
 smoked, canned, etc., so that the usefulness is increased by the possibility 
 of shipping them long distances and preserving them indefinitely. In 
 this exhibit the principal food objects are shown in natural groups. 
 Fishes are represented by stuffed and painted skins, and by colored and 
 plain drawings, in addition to the living specimens in aquaria ; oysters, 
 clams and other mollusks occupy a number of cases, the collection 
 embracing practically all those economically important for either food or 
 bait ; the exhibit of economic crustaceans is equally comprehensive, 
 including nearly all the crabs, shrimps, lobsters and related forms which 
 enter into the food supply or are employed as bait in the line fisheries ; 
 and terrapins, turtles and other edible reptiles are represented by a series 
 of polished shells. 
 
 The leading food products of the fisheries are shown in a small but 
 comprehensive display of canned, smoked, salted and pickled goods. 
 
 The secondary products of the fisheries, also of considerable and 
 increasing value, are illustrated as completely as possible. The principal 
 of these are fertilizers, glues, oils and isinglass. From the skins of cod, 
 cusk and other fishes, a superior glue is manufactured which is taking 
 the place of most other adhesives, and is susceptible of being prepared for 
 many special purposes ; being in liquid form it is more convenient for 
 use. These skins were formerly thrown away as waste, but now, after 
 having been cooked and the glue extracted, they are again used in the 
 manufacture of an excellent fertilizer. Fertilizer is also produced from 
 the waste in canning various other species and from the residuum of 
 fish oil. The best and most extensively manufactured fish fertilizer is 
 made from the menhaden, which is comparatively valueless as food and 
 is found in great quantities along the Atlantic coast. Isinglass, used for 
 clarifying beer and wine, for culinary purposes, and for its adhesive 
 properties, is made from the air-bladders or sounds of various fishes. Of 
 the domestic fishes, the sounds of the hake, weak-fish and cod are chiefly 
 used, but numbers are imported — the Eussian sounds obtained from the 
 sturgeon being considered superior. A comprehensive series of oils, 
 obtained from fishes, and valuable for medicinal or mechanical purposes, 
 is shown. The best known and most extensively used are cod-liver, whale,

 sperm and menhaden oils, but many others are particularly adapted for 
 special uses, for which they are superior to other animal and mineral oils, 
 though the latter, on account of the relatively small cost, are superseding 
 them. Porpoise-jaw and blackfish melon oil are especially valuable for 
 clocks and watches and lubricating other delicate machinery. 
 
 The skins of water animals, including fishes, are largely utilized in the 
 manufacture of leather goods of all kinds, and their use could probably 
 be extended. Alligator leather is familiar to all, and the seal, walrus and 
 sea- lion skins also furnish particularly fine leathers which are susceptible 
 of being woi'ked to a high degree of pliability, dyed in a great variety of 
 colors, and, like alligator leather and the skins of some water snakes, are 
 used for making bags, purses, cases, pocketbooks, belts, picture frames, 
 etc. A number of these leathers, and others suitable for similar purposes, 
 are shown, and include the skins as they appear when first tanned and the 
 leathers dressed and dyed for different purposes. Porpoise leather is par- 
 ticularly valuable for shoes and shoe laces, being durable and waterproof, 
 as is also leather made from the skin of the white whale or beluga, and 
 the latter on account of its tensile strength is adapted for belting. Eel 
 skins are used in great numbers in manufacturing whips. The skins of 
 several species of rays and of the dog-fish, gar pike, whale, manatee and 
 beaver are exhibited. The former are used by the Japanese for covering 
 sword hilts and for other ornamental purposes, and, as well as the others, 
 to some extent in this country in manufacturing picture frames, fancy 
 articles, and for other special purposes, though more coarse, brittle and 
 harder to work than the leathers first mentioned. 
 
 Ivory, bone and shell are among the products of the fisheries used to 
 a certain extent in the arts and industries, and there are shown examples 
 of walrus and narwhal tusks, sperm-whale teeth, baleen or whalebone, and 
 the well-known tortoise shell in the form of shells, rough and polished, 
 of the hawksbill or tortoise-shell turtle. 
 
 The shells of mollusks are employed for various purposes. A compar- 
 atively new use to which those of our fresh- water mussels have been put 
 is in the manufacture of pearl buttons. This business, while only estab- 
 lished a few years ago, has attained large proportions in the Mississippi 
 basin. A full series of the shells utilized in button-making is shown, to- 
 gether with buttons in various stages of manufacture. The mollusks 
 yielding shells suitable for buttons also produce beautiful and valuable 
 pearls and baroque pearls, examples of which are exhibited. The better- 
 grades of pearl buttons and ornaments are produced from marine shells, 
 which afford a finer and more lustrous grade of mother-of-pearl. These 
 are found principally in tropical waters, and brought to the United States 
 for manufacture. The so-called pearl-oyster, which is the principal shell 
 utilized, is found in the Gulf of California and in the Philippines, and the 
 abalone is common on the California coast. 
 
 The fisheries supply valuable articles of wearing apparel in the form of 
 furs, which are shown in their natural state and " plucked and dyed " 
 ready for manufacture. Large numbers of fur-seal skins are still obtained 
 
12 UNITED STATES FISH COMMISSION. 
 
 annually from the seal fisheries controlled by the United States on the 
 Pribilof Islands in Alaska. These are considered the best and are com- 
 mercially known as Alaska seal. Nearly all seal skins are dressed and 
 dyed in Europe and returned to this country in a finished state ready to 
 be made into garments. The sea otter found in Alaska furnishes the 
 most valuable fur, and is comparatively rare. It is mainly used as a 
 trimming for coats and garments, and, as it has naturally a peculiar deli- 
 cate silvery appearance, it is not dyed. Other fur-bearing aquatic ani- 
 mals taken in various parts of the United States are the fresh-water otter, 
 beaver, and muskrat, an enormous number of the skins of the latter being 
 taken annually. A coarse fur, from which are manufactured robes, cheap 
 o-loves, etc., is obtained from the common hair seal of the Atlantic coast.

 Among other objects related to the fisheries are shown seaweeds 
 mounted and prepared for market. These are utilized in this country to 
 some extent in preparing food, for fertilizers, etc., and many varieties com- 
 mon along our coasts are extensively used in foreign countries, and are 
 of commercial importance. From some species iodine is obtained. 
 
 In curing fish different kinds of salt are employed, the choice being gov- 
 erned by the strength and coarseness as applied to different fishes. In 
 New England, Trapani salt, imported from Sicily, is used for cod, had- 
 dock, halibut, and other coarse fishes, and Liverpool salt, though less 
 strong and clean, for mackerel, because of the smaller grains. On the 
 Southern rivers and coast, Turks Island salt is found desirable, while on 
 the Great Lakes domestic salt is used. On the Pacific coast marine salt, 
 made by evaporating sea water, is most economical and is of excellent 
 quality. For the manufacture of caviar a fine salt, imported from Ger- 
 many and known as Luneburg, is especially prepared. 
 
 The apparatus and methods of the commercial fisheries are fully illus- 
 trated by actual specimens, by models, by colored photographic enlarge- 
 ments and by mutascope scenes. 
 
 Models of the types of modern fishing vessels illustrate the vessel fish- 
 eries of the Atlantic and Pacific oceans and the Gulf of Mexico, particular 
 attention being paid to the Grand Bank cod-fishing, the mackerel fishery, 
 and the market fishery of Gloucester and Boston, Massachusetts. The 
 various types of pound nets, seines, trawls, hand lines, etc., used in 
 the commercial fisheries are illustrated by models and by full-sized speci- 
 mens where space permits, together with dredges, tongs and other articles 
 used for taking oysters, scallops, clams, turtles and sponges. 
 
 One of the most interesting exhibits is a collection of the various types 
 of swivel guns, shoulder guns, rocket guns, harpoons, lances and other 
 implements that have been used for the capture and handling of whales 
 by the fishermen of this country. 
 
 Among the specially instructive exhibits illustrating fishing methods 
 and apparatus are a large working model of a Columbia river salmon 
 wheel, a model of the Florida sponge fishery, and models of some of the 
 most important of the marine fisheries of the northeastern coast.

 having important fisheries and also being the site of extensive fish-cultural work. 
 The model represents the bed of the river, with rack, traps, and pens used for inter- 
 cepting, catching, and retaining salmon from which eggs are to be taken for hatching 
 purposes. 
 
 Improved Cail Fishwat. 
 
 [Scale of model, 1 inch to the foot. Inclination, 1 to 4.] 
 
 A series of comparatively still-water compartments arranged in steps and separated 
 by cross bulkheads with suitable openings allowing the fish to ascend the fishway by 
 either leaping the small waterfalls over the bulkheads or passing through the open- 
 ings. This fishway can be constructed of either timber, masonry, or concrete, and on 
 a straight line or angles and curves, as the conditions may require. It is applicable 
 to the various forms of existing dams and natural falls, and owing to the abundance 
 of light through the open spaces on top can be readily inspected and the de'bris

 easily removed. Protection against drift ice and logs during freshets is provided, and 
 there are no regulating gates or other devices requiring an attendant. The floor 
 compartments are slightly inclined, and the bulkheads run obliquely in order that 
 the current passing through can readily clear gravel, sand, mud. and other rubbish, 
 which is an improvement over many other types of flshways. The original fishway 
 was designed by Mr. Richard Cail and is used successfully in Scotland. 
 
 Improvements were made by H. von Bayer, architect and engineer of the U. S. 
 Fish Commission, as follows: (1) Beginning at the top the openings in bulkheads 
 are decreased successively so as to insure an overflow over each bulkhead down to 
 the lowermost in case of any leakage in the fishway. (2) The bulkheads are placed 
 obliquely across the fishway, so as to make each compartment self-cleaning.

 Apparatus foe Teanspoeting Eggs. 
 
 Clark white-fish egg box : 
 
 Wooden case, with hinged door, containing twenty trays. This case is used 
 chiefly for the transportation of the eggs of the white-fish and lake trout from field 
 stations on the Great Lakes, and was designed by Mr. Frank N. Clark, of Northville, 
 Mich. Eggs have frequently been held on these cases from fifteen to thirty days 
 before they reached the hatchery, without suffering material loss. 
 
 Annin's egg-transportation box: 
 
 This apparatus consists of an outer case which contains a smaller one, surrounded 
 by sawdust to prevent loss of eggs from sudden change of temperature. The inner 
 case is provided with trays, with canton-flannel bottoms, for holding the eggs. 
 There is a small ice chamber between the outer and inner boxes, and the bottom of 
 the outer box is provided with wooden strips to prevent its coming in contact with 
 the surface on which it rests, which would prevent drainage. 
 
 Devised by James Annin, Jr., Caledonia, N. Y. Boxes of this patent have been 
 used for sending eggs of trout to Europe. 
 
 Atkins's transportation box: 
 
 A wooden box containing three smaller boxes, in each of which 15,000 salmon eggs 
 are placed upon layers of muslin. The space between the larger and smaller boxes 
 is filled with moss to prevent an unhealthy change of temperature, and the layers of 
 eggs are separated from each other by wet moss. Eggs packed in this way can be 
 sent several thousand miles with very satisfactory results. 
 
 Devised by Charles G. Atkins, East Orland, Me. 
 
 SeagWs egg-transportation box : 
 
 This apparatus consists of a wooden box, with hinged cover, 21 inches long, 19 
 inches wide, and 18^ inches high, containing 6 canton-flannel trays, 11£ inches by 9k 
 inches, on which the eggs are placed, packed in moss. A wooden hopper above the 
 trays holds crushed ice, and the space around the trays is tightly packed with sphag- 
 num moss. Eggs of the Salmonidae are successfully transported long distances by 
 means of this apparatus. 
 
 Devised by George A. Seagle, Wytheville, Va. 
 
 McDonald's egg-transportation crate: 
 
 A crate containing eighteen shallow trays or wooden frames, with wire-cloth bot- 
 toms, incased in canvas and secured by frames connected by leather straps. Length, 
 16 inches; height, 15 inches; width, 14 inches. This crate is used for transporting 
 the eggs of the shad for a distance of 50 to 100 miles. The bottoms of the trays are 
 covered with wet cloths, upon which the eggs are spread. Each tray holds from 
 10,000 to 15,000 shad eggs. When filled they are incased in the cloth cover, securely 
 strapped together, and shipped by boat or rail to the hatchery. This apparatus 
 marks the beginning of the dry transportation of shad eggs, and has been success- 
 fully used in the work of the U. S. Fish Commission since invented. 
 
 Invented by Marshall McDonald, 1881. 
 
 Appaeatus and Accessoeies for Teanspoeting Fry. 
 
 Model of U. 8. Fish Commission Car 1 No. 3 (scale of 1 inch to the foot) : 
 
 This car was built in Wilmington, Del., by the Harlan & Hollingsworth Company 
 in the month of November, 1897. Total length of frame, 60 feet ; width of frame. 
 
LOUISIANA PURCHASE EXPOSITION. 15 
 
 9 feet 6 inches ; total length of car from ends of platforms, 67 feet 10 inches ; height 
 of car from top of rail to top of roof, 13 feet 10 inches. The frame of the car has a 
 special bracing in order to allow the two large doors in the center of the car to extend 
 from floor to roof. The trucks for the car were made by the Pullman Company, each 
 of them having six 33-inch Allen paper wheels. The interior finish of the car is of 
 light-color ash. In one end of the car is an office, and next to it an ice box — capacity 
 of about H tons — and a water tank holding about 500 gallons. In the center o" the 
 car are two compartments for carrying its load. The fish are carried in cans and 
 square tanks, according to the size of the fish. The size of these compartments is 
 30 feet long, 3 feet wide, and 25 inches deep. A hatching apparatus of a capacity of 
 45 McDonald jars is also used on this car. and is placed on the top of the two com- 
 partments for carrying fish after moving the lids. The jars are placed in lead-lined 
 boxes, which are of the same size as the lids and about 6 inches high. The supply of 
 water is taken from the pressure tank. It flows from the lead-lined boxes through a 
 system of piping to the storage tank underneath the car. The hatching can be done 
 while the car is in motion. In the other end of the car is a kitchen and boiler room. 
 The boiler room contains a 5-horsepower boiler, with water pumps and air pump for 
 circulating the water and air on the fish. Underneath the car, between the trucks, is 
 a storage tank which will hold about 600 gallons. The water is pumped from this 
 tank to a pressure tank near the office end of the car, after which it circulates through 
 the square tanks or batching apparatus in the center of the car, passing from these to 
 the tank under the car again, so the water is used continuously. In the center of the 
 car are four berths, together with a number of lockers and closets. The office con- 
 tains one berth and a folding bed ; also a writing desk and closet. The kitchen is 
 fully equipped with range, water tanks, etc. 
 
 Transportation can : 
 
 A cylindrical can, made of iron, tinned, the top of which is contracted and provided 
 with a cover to pi-event splashing of water while in transit. Height, 24 inches ; 
 diameter, 14 inches; capacity, 12 gallons. This can is more extensively used than 
 any other form of apparatus for the transportation of young shad, white-fish, pike 
 perch, trout, and other fishes distributed by the U. S. Fish Commission. 
 
 Qalvanized-iron transportation tank : 
 
 This tank (size, 24 by 24 by 24) is used on U. S. Fish Commission cars for trans- 
 porting adult fishes and yearlings over 6 inches in length. It is so arranged as to 
 receive a continuous supply of air, and can also be connected up with the water- 
 supply tanks so that a continuous circulation of water is maintained. 
 
 Tin pail for rock bass : 
 
 A light tin pail, with a capacity of 2 to 4 quarts, used in shipping rock bass and 
 bream by express. 
 
 Bucksport transportation can : 
 
 A cylindrical can, made of block tin, with top contracted, and provided with a 
 cover, 18 inches in height and 15^ inches in diameter at basf. This can is used 
 entirely at the Craig Brook (Maine) Station for transportation of salmon fry. 
 
 Messenger bucket : 
 
 This bucket forms a part of a messenger's equipment, and is used for carrying extra 
 ice, changing water, etc. 
 
 Quart dipper : 
 
 A part of the messenger outfit, used for aeration of water, sorting fish, etc. 
 
 Siphon cage : 
 
 Made of copper and tin. It is covered with cheesecloth and attached to the siphon 
 tube for drawing off water from aquarium or cans containing fry. 
 
 Tin siphon funnel : 
 
 A cylindrical funnel, with fine perforations at bottom, a part of the messenger's 
 outfit. Used in drawing off water from tanks containing shad and white-fish fry. 
 
 Siphon tube : 
 
 A piece of five-eighths rubber tubing, 4 feet long, used in connection with a siphon 
 strainer for removing stale water from cans containing young fish. 
 
 Pocket thermometer : 
 
 This forms a part of a messenger's equipment, and is regularly used for ascertaining 
 the temperature of water while transporting fish.

 Hatcheries, Hatching Apparatus and Accessories. 
 
 Model of Leadville trout hatchery (scale of model, three-fourths inch to 1 foot): 
 
 The station is located in Lake County, Colo., 6 miles west of Leadville, on a gov- 
 ernment reservation of 1,935 acres. It was established by act of Congress approved 
 March 2, 1899, for the purpose of propagating black-spotted and other native species 
 of trout, as well as various fishes of the salmon family from the Eastern stations. 
 The hatchery is built of red sandstone, is equipped with 72 troughs, each 14 feet 
 long, 14 inches wide, and 8 inches deep. It has a total capacity of 6,000,000 trout 
 eggs. The water supply is obtained from Rock Creek and springs on the reservation. 
 The temperature of the water throughout the year varies from 37° to 46°, the mean 
 being 43*. 
 
 Model of hatching barge : 
 
 The barges were generally equipped with hatching cones and Ferguson plunging 
 buckets, and were extensively used by the U. S. Fish Commission for many years in 
 the waters of Noith Carolina, Virginia, and Maryland in batching the eggs of the 
 shad. After the establishment of permanent shore stations the use of the barges was 
 abandoned. 
 
 Cod box : 
 
 This apparatus consists of a series of double rectangular wooden boxes, usually 
 arranged in nests of 8 or 9. The eggs are placed in the inner box, the bottom of 
 which is slightly oval instead of flat, and is covered with scrim cloth. The water is 
 introduced from the water chamber through the bottom and through a hole several 
 inches above the bottom, which gives the eggs a slightly rotary motion ; it escapes 
 through an intermittent siphon, which produces the tidal motion essential in hatching 
 floating eggs. 
 
 Originally designed by Marshall McDonald in 1880 and perfected in 1888. 
 
 Model of plunging buckets : 
 
 This model illustrates the methods employed in hatching shad during the early 
 days of the Commission. It was invented by Maj. T. B. Ferguson in 1880 and was 
 used in the Chesapeake Bay and on the Albemarle Sound. The plunging buckets 
 were on the outside of a barge which was fitted up with the machinery necessary 
 for operating the same. It has also been used with slight success in the hatching of 
 floating eggs. 
 
 McDonald's Y-shaped hatching box: 
 
 A wooden box, with glass ends and sloping sides, for eggs. Length, 12 inches ; 
 width, 24 inches; depth, 15 inches. The sides of the box slope toward the bottom 
 center until they come within an inch of each other. Below this opening is a space 
 3 or 4 inches deep, for the introduction of water. This opening is nearly closed by 
 means of an adjustable square wooden bar, one of the angles of which enters the cen- 
 ter of the opening, the sides of the bar thus being parallel with those of the box. 
 By this means the current is divided, so that the water is deflected along either side 
 of the box toward the surface, carrying the eggs with it and causing them to pass in 
 toward the center and fall again to the bottom, where they are again caught by the 
 current and carried through the same circuit. The outlet is protected by a triangu- 
 lar trough running across the top center from side to side. This is placed a little 
 below the top of the box, so that the water shall flow over its side and out through 
 the openings. The current introduced is sufficiently strong to carry dead eggs into 
 this trough, thus allowing them to escape, but not strong enough to carry away the 
 good eggs, which, being heavier than the dead ones, drop before reaching the trough. 
 Great care must be taken to see that the flow of water is properly adjusted, otherwise 
 many of the dead eggs may be retained or the good ones may be lost. 
 
 Invented by Marshall McDonald in 1881. 
 
 Williamson hatching trough with Stone salmon basket : 
 
 A section of the hatching trough, showing three compartments complete, with 
 three tiers of wire trays in each. In the trough a double partition separates each 
 compartment, the first extending from the bottom of trough to within an inch of the 
 top, while the second extends from the top to within an inch of the bottom, the two 
 sections of the partitioning being 1 inch apart. The water passing over the first par- 
 tition and under the second, into the compartment, forces its way up through the 
 eggs on the baskets and over and under the next partitions. 
 
LOUISIANA PURCHASE EXPOSITION, 17 
 
 Trout trough with wire trays : 
 
 This is an ordinary trout trough, 8 feet long, 12^ inches wide in the clear, and 6 
 inches deep, litted with ordinary galvanized-iron wire trays, 7 meshes to the inch. 
 Used at most of the hatcheries in the Commission for hatching brook, rainbow, and 
 black-spotted trout eggs. The troughs in the hatcheries vary in length from 12 to 16 
 feet. Both the trays and troughs are painted with asphaltum varnish. Wire trays 
 for the hatching of trout eggs were first used in 1867 by Mr. E. A. Brackett, of 
 Winchester, Mass. 
 
 Ferguson hatching-jar : 
 
 A cylindrical jar of glass, with a contraction near the base, which serves as a sup- 
 port to the 7 wire-cloth egg-trays which it contains. It has two circular openings on 
 opposite sides — one at the bottom for admitting the water, which passes upward 
 through the eggs and out through the second opening, which is situated at the top. 
 Height, 12 inches ; diameter, 8 inches. For economy of water, the outflow opening 
 of one jar is connpcted with the inflow pipe of the next by means of rubber tubing. 
 By this means the water passes through an entire series of jars before it finally 
 escapes. The jar is used chiefly for hatching eggs of the Salmonidae. It holds about 
 4,000 salmon eggs or 6,000 trout eggs. 
 
 Invented by T. B. Ferguson, 1876. 
 
 Atkins's hatching -crate : 
 
 A frame of metal and wood, with hinged cover, which incloses a nest of 9 egg- 
 trays. Length, 12 inches; width, 12 inches; depth, 7 inches. This crate is used 
 chiefly for hatching eggs of the Salmonidse. The trays are provided with corner 
 strips of wood, which separate them slightly from each other to allow free circula- 
 tion of water, though the spaces are not large enough to allow the escape of eggs. 
 These crates can be placed either in the open stream or in ordinary troughs. 
 
 Designed by Charles G. Atkins, Bucksport, Me.; presented by Mr. Atkins. 
 
 McDonald hatching -jar, old style : 
 
 Similar to improved jar now in use ; but. instead of a metal cap, cork was used for 
 the stopple. Invented in 1881 ; superseded in 1883 by improved McDonald jar. 
 
 Chase hatching-jar : 
 
 A cylindrical jar of glass, with a metal rim notched at one side and provided with 
 a wire screen for retaining the fish. The water is introduced through a glass tube at 
 the bottom and passes upward through the eggs. Height, J 6 inches; diameter, 6 
 inches. This jar is extensively used for hatching eggs of the white-fish. When the 
 embryos are developing the outflow gate remains open, and through it any dead 
 eggs are carried upward by the current and escape, thus preventing the injurious 
 effects which arise from fungus and dead eggs. 
 
 Invented by Oren M. Chase, Detroit, Mich. 
 
 Clark hatching-jar : 
 
 A cylindrical jar of glass, with a metal rim, having a spout at one side, from which 
 the surplus water escapes. The bottom of the jar is provided with a metal cone 
 corresponding with the funnel-shaped end of the supply tube, which is prevented 
 from coming in contact with it by means of slight projections on its inner surface. 
 Height, 18 inches ; diameter, 6 inches. This jar is coming into favor for hatching 
 eggs of the white-fish, and is used extensively at the Northville hatchery. 
 
 Designed by Frank N. Clark, Northville, Mich. 
 
 McDonald white-fish jar : 
 
 This is the same as the jar used for hatching shad, known as the McDonald uni- 
 versal hatching-jar, with the exception that the closed top is removed and an open 
 top with a tin funnel 3^ inches long substituted in its place, through which the water 
 escapes. The tube supplying the water is suspended from above to within one-eighth 
 of an inch of the bottom of the jar, and is made of either glass, tin, or iron. 
 
 McDonald's universal hatching-jar : 
 
 A glass jar with metal cap, containing two circular openings. Through one of 
 these, which is situated in the center, a glass tube for the introduction of water passes 
 to within a short distance of the bottom of the jar. The other, situated near one 
 
18 UNITED STATES FISH COMMISSION. 
 
 side, contains a shorter glass tube, which serves as an outflow pipe. Height. 15 
 inches ; diameter, 6, inches ; capacity, 5 quarts. The McDonald jar is successfully 
 employed in the hatching of various species of heavy eggs. The water in entering 
 is thrown against the bottom with considerable force, and is deflected upward around 
 the sides of the jar. The eggs, which tend to settle to the bottom, are carried upward 
 along the sides, thence inward toward the center, from which point they again sink 
 to the bottom. The current is regulated to give the desired motion to the eggs. 
 With heavy eggs like those of the salmon there is no motion, but the water comiDg 
 from beneath tends to buoy the eggs upward, thus preventing any injurious pressure 
 on the lower ones by the mass above. The outflow pipe is movable, and can be 
 lowered to a point where the dead eggs, which are lighter than the good ones, come 
 in contact with it and are carried off. By this means the eggs are kept comparatively 
 free from the injurious effects of fungus growth or decaying eggs. The jar can be 
 filled two-thirds full of eggs with very satisfactory results, 75,000 shad eggs being 
 considered a fair quantity. 
 
 Patented by Marshall McDonald, Washington, D. C, in 1882. 
 
 A quaria : 
 
 Receptable, rectangular in shape, made of glass, slate, and iron ; 48 inches long, 
 
 18 inches wide, 18 inches deep; into which the fry pass from the jars as soon as they 
 are hatched. The aquaria is placed in the center of the hatching-table and receives 
 the fry from about 14 or 15 jars ; as soon as they become crowded ihey are transferred 
 to the fry troughs usually arranged around the hatchery.

 Perforated ladle : 
 
 An ordinary iron cooking ladle, with perforated bowl, used in handling trout eggs 
 during the period of incubation in the hatching troughs. 
 
 Perforated dipper : Used in handling trout eggs during incubation. 
 
 Seagle hatching -trough : Model with sliding screen instead of fixed screen in head of 
 trough. Advantage claimed in cleaning trough with young fish in it. 
 
 Egg nippers : 
 
 Made of wood, tin, and brass, of various styles, for removing dead and unimpreg- 
 nated trout and salmon eggs. 
 
 Page's egg scale : 
 
 A small wooden square laid off in grades and numbers. The scale is designed to 
 determine the number of eggs of any species in a McDonald hatching-jar. The grades 
 correspond to one-half pint contents of the jar, and the number of eggs per half pint 
 has been determined by counting 1 quart of eggs of each species. 
 
 Measure for counting white-fish eggs : 
 
 Devised by Mr. J. J. Stranahan, of Put-in Bay, Ohio, for counting rapidly a quart 
 of white-fish eggs— applicable to any other species. 
 
 Feathers : Used in cleaning and manipulating trout and salmon eggs. 
 
 Outfit and Apparatus for Collecting Fish Eggs. 
 
 The spawn-taker : 
 
 This lay figure represents a man in the act of taking the eggs from a ripe salmon. 
 The fish casts in front of him show the condition of the ovaries and spermaries of ripe 
 male and female salmon. 
 
 Spawn-taker's bucket : 
 
 Part of a spawn-taker's outfit, and is principally used iu the collection of shad eggs. 
 After the eggs have been fertilized and all of the pans refilled they are emptied into 
 the bucket, where they are held until they reach the hatchery, the water being changed 
 from time to time. 
 
 Spawning pans : 
 
 May be of either tin, wood, or marbleized iron, and form a part of a spawn-taker's 
 outfit in collecting eggs of white-fish, trout, shad, etc. 
 
 Collins 's egg pan : 
 
 An oblong pan with a tumble-in top, provided with an iron bail and cover, the latter 
 preventing loss of eggs from slopping out, and the former facilitating the handling of 
 apparatus in the boat. Pan is 18^ inches long, 10^ inches wide, 8^ inches high, with- 
 out cover; tinned and shellacked inside to prevent the iron corroding from contact 
 with sea water. Designed by Capt. J. W. Collins. 
 
 Salmon spawning box or jacket : 
 
 A wooden box 42 inches loug and tapering from 8| inches to 3| inches in height, 
 and from 5 inches to lh inches in width. This box is used on the Columbia and 
 Rogue rivers in stripping ripe salmon. The fish is placed on its back in the box, its 
 head being secured with wooden slide and tail by a strap attached near the small end 
 of the box, and is readily stripped by one man, whereas two or perhaps three men 
 would be required without the box.

 Vessels and Appliances foe Deep-sea, Pelagic, Shore, and Fbesh-water 
 
 Investigations. 
 
 Model of the Albatross : 
 
 The steamer Albatross was built expressly for marine exploration, and intended es- 
 pecially for investigating the offshore fisheries and fishing-grounds of the United States. 
 It is an iron twin-screw steamer, and was built in 1882 by the Pusey & Jones Company, 
 of Wilmington, Del. General dimensions: Length, over all, '234 feet; at 12-foot 
 water line, 200 feet ; breadth of beam, 27 feet 6 inches ; displacement, on 12-foot 
 draft, 1,000 tons ; registered tonnage, net, 400 tons. 
 
 The Albatross has recently carried on important investigations of the marine 
 resources of the Hawaiian Islands and Alaska. 
 
 Model of the Fish Hawk : 
 
 The steamer Fish Hawk is a twin-screw propeller of 205.71 tons measurement; is 
 rigged as a fore-and-aft schooner, with pole topmasts, and constructed for the com- 
 bined purpose of fish-hatching and exploration. She was designed by Charles W. 
 Copeland, and built in 1880 by Pusey & Jones, of Wilmington, Del. The work of 
 fish-hatching necessitates her entering, at times, the shallow waters of rivers, bays, 
 and sounds along the coast, and she was, therefore, given a light draft, which unsuits 
 her for long trips at sea. The hull below the main deck is of iron, built on Lloyd's 
 rules for vessels of her class, and sheathed with yellow pine 2h to 3 inches thick. 
 Above the main deck the structure is of wood. The hurricane deck extends from 
 stem to stern and from side to side, on which are located the pilot house, captain's 
 quarters, and laboratory. General dimensions : Length over all, 156 feet 6 inches ; 
 breadth of beam, 27 feet ; mean draft, 6 feet 5^ inches. 
 
 Tanner sounding machine and instruments for deep-sea physical research: 
 
 The Tanner sounding machine is used in depths not exceeding 500 fathoms (3,000 
 feet). For greater depths the Sigsbee machine, which reels in sounding wire by steam 
 power, is used. On both machines steel piano wire is used in place of the hemp sound- 
 ing lines formerly employed, its advantages being strength, lightness, and small bulk. 
 With it heavier sinkers can be employed to give an up-and-down trend, and its smaller 
 surface per linear foot renders it less liable than the hemp lines to be diverted from 
 the vertical by currents. A 65-pound shot on the sounding cylinder is automatically 
 detached when the bottom is reached, in order to lessen the tension when reeling in. 
 The sounding cylinder brings up a specimen from the bottom, the water cup takes a 
 sample of water within a few feet of the bottom, and the deep-sea thermometer auto- 
 matically records the bottom temperature. 
 
 With the Sigsbee machine the Albatross recently found a depth of 4,813 fathoms 
 (about 5h miles), one of the deepest oceanic depressions in the world, about 100 miles 
 southeast of Guam. The highest mountain in North America would be covered by 
 nearly 2 miles of water if placed in this depression. 
 
 Beam trawl : 
 
 A beam trawl is displayed, fully rigged and arranged in the position which it 
 assumes when in use. This is the most efficient piece of apparatus employed in col- 
 lecting specimens from the bottom of the sea, in either shallow or deep water. The 
 one exhibited is the smallest used on the vessels of the U. S. Fish Commission, meas- 
 uring 6 feet across the mouth; the largest form in general use is 11 feet across the 
 mouth, and the other dimensions are correspondingly larger. The frame is composed 
 of two iron runners connected at the top by a transverse beam of iron piping, to which 
 the upper part of it is secured. The net consists of an outer bag about 18 feet long, 
 having the lower side of its mouth heavily loaded with lead sinkers to insure its drag- 
 ging closely on the bottom. Immediately back of the mouth it is provided with an 
 internal, funnel-shaped apron, to prevent the escape of animals which have once 
 entered, and for 6 feet at the bottom there is also an inner pocket of small-meshed 
 netting to hold the smaller specimens. A thick-walled spherical glass float is attached 
 to the upper side of the net near the mouth, so as to hold it open when immersed. 
 The lower end or tail of the net is closed by a secure lashing, which is removed after 
 each haul for the discharge of the specimens into table sieves on the deck of the ves- 
 sel, where they are washed, sorted, and preserved for futute study. The trawl is 
 dragged by a steel rope which will bear a strain of 7 tons, rigged to a heavy bottom

 attached to the foremast. The trawl is lowered and hauled in by steam power. 
 With a net in general design similar to the one exhibited the Albatross has obtained 
 specimens in water over 4$ miles deep. 
 
 Tangle bars : 
 
 Used to collect specimens where the bottom is so foul or rocky that the beam trawl, 
 or any other form of net, would be torn or otherwise seriously injured. It is by no 
 means as efficient as the trawl, but on rocky or coral bottom it is practically the only 
 appliance which can be used, and it frequently catches numerous specimens of star- 
 fishes, sea urchins, corals, crabs, shrimp, fishes, and other animals which become 
 entangled in the mops. The bow at the angle of the bars is made of tempered steel, 
 so that the legs will close up on one another like a pair of dividers if the frame becomes 
 fouled in the rocks. The tangles are dragged over the bottom by the wire used for 
 trawling. 
 
 Chester rake dredge : 
 
 For use from large vessels in collecting burrowing species of fish, mollusks, worms, 
 etc., on hard mud or sand bottom. 
 
 Smith rake dredge : 
 
 For use from a small boat in collecting burrowing species of clams, worms, etc., on 
 hard mud or sand bottom. 
 
 Large boat-dredge : 
 Used for collecting specimens from the bottom. 
 
 Small boat-dredge : 
 Used for collecting specimens from the bottom. 
 
 Surface tow-net (31- feet) : 
 
 Used for collecting surface-swimming and floating plants and animals. The outer 
 bag of netting serves as a support to the lining of cheesecloth used to retain the more 
 minute organisms. The funnel prevents the escape of active species of shrimps and 
 fishes. After a towing is made the tail lashing is removed and the specimens washed 
 into a basin of water, from which they are picked out and transferred to preservatives. 
 The net is usually towed at a speed of about 2 knots per hour. 
 
 Tanner intermediate tow-net for taking specimens at known depths : 
 
 This net is lowered vertically to the required depth and towed for a definite time. 
 A weight or messenger is then sent down the wire, which reverses the tumbler, casts 
 off the bridles, and allows the weights on the legs of the frame to exert a strong pull 
 on the drawstring and securely close the bottom half of the net. 
 
 Townsend intermediate tow-net : 
 
 Used like the Tanner net. The ring is hinged and the two halves are closed on 
 one another by a device actuated by a messenger slid down the rope. 
 
 Surface tow-net {silk gauze) : 
 Used for catching small and microscopic organisms at the surface. 
 
 Baird seine : 
 
 This is a type of seine especially devised and used for collecting fishes and, inci- 
 dentally, other water animals. It is rigged with floats and leads like ordinary seines, 
 but has as its distinctive features a very fine mesh and a large bag in the center where 
 the catch gravitates and can be most conveniently overhauled. Two persons are re- 
 quired to operate it, and it may be set from a rowboat or by wadiug. The standard 
 lengths of collecting seines used by the Commission are 15, 25, 45, 75, and 120 feet. 
 
 Gill nets : 
 
 Gill nets of various sizes and types, similar to those employed in the commercial 
 fisheries, are used in collecting and determining the nature of the fish life in waters in 
 which other kinds of apparatus cannot be so conveniently or effectively employed. 
 
22 UNITED STATES FISH COMMISSION. 
 
 Dip nets, scrape nets, etc. : 
 
 Various forms of hand nets, intended to be used from boats, wharves, or shores, are 
 required in collecting small fishes and invertebrates that are swimming in the water, 
 resting on the bottom, or attached to piling, rocks, etc. 
 
 Collecting tank and chest : 
 
 For use in the field and in shipping collections the Commission has adopted a stout 
 chest with handles and padlocks. The chest accommodates one 16-gallon tank, two 
 8-gallon tanks, or four 4-gallon tanks, made of sheet copper with tightly fitting screw 
 tops. 
 
 Portable collecting outfit : 
 
 For use from small sailboats and launches. It consists of a chest containing : one 
 3-foot beam trawl, one 3-foot tangle frame and swabs, one small dredge, one 2-foot 
 folding tow-net, one gauze tow-net, two seives with arms and brackets adjustable to 
 the sides of any small craft, dredge ropes, etc. It can be carried as baggage.

 It turns the stomach inside out and projects it through its mouth and around its 
 food. When satisfied the stomach is returned to its proper place. 
 
 Common starfish. Taken in the act of feeding on oysters. The starfish wrenches 
 open the oys'ter by a long, steady pull, and then inserts its stomach between the 
 valves as explained above and absorbs the contents. 
 
 Oyster drill. Very destructive to oysters on certain parts of the Atlantic coast. 
 By means of a rasplike tongue it drills a hole in the shell, through which it feeds on 
 the soft parts of the oyster. It has unfortunately been introduced with eastern 
 oysters in San Francisco Bay.

 Special Investigations of the Soft-shell Clam (Mya arenaria). 
 
 The investigations represented by this collection were made in Narragansett Bay, 
 Rhode Island, by the Rhode Island Commission of Inland Fisheries in collaboration 
 with the United States Fish Commission. 
 
 The first six series of specimens illustrate the rate of growth of clams under several 
 different conditions ; the last series illustrates the difference in the rate of growth of 
 clams of different sizes under the same conditions. 
 
24 UNITED STATES PISH COMMISSION. 
 
 The clams spawn from May to July, and attain sexual maturity in one year. They 
 reach a length of three inches under especially favorable conditions in about one year 
 and three months, but usually require two years. 
 
 The microscopic swimming larvaa, or spat, may be artificially collected, or may be 
 found occasionally on the shore in great quantities. The raising of clams by trans- 
 planting is practicable.

 Special Investigation of the Scallop (Pecten irradians). 
 
 The investigation of the life history of the scallop was made by the Rhode Island 
 Commission of Inland Fisheries in collaboration with the United States Fish Com- 
 mission. The mounted specimens illustrate the rate of growth of the scallops in 
 Narragansett Bay, Rhode Island, during the first two years and four months. 
 
 The scallops die in great numbers in February and March of the second year, and 
 rarely live two years. They spawn in June when one year old. The growth is rapid 
 from June to December of the first and second years, but very slow from January to 
 June. Immediately after spawning the period of rapid growth begins, causing a dis- 
 tinct growth line to appear on the shell, parallel to the margin. The presence of this 
 line, therefore, indicates that the scallop is more than one year old. The compara- 
 tively few specimens more than two years old have a second growth line. 
 
 Eighteen lots of scallops, illustrating rate of growth : 
 
 From Wickford, Greenwich, and other points in Rhode Island. 
 
 Studies of the Staefish. 
 
 The common starfish {Asterias forbesii) is very destructive to oysters, and a know- 
 ledge of its growth has an important economic bearing. All the specimens shown 
 were reared at the house-boat of the Rhode Island Fish Commission, and their a^es 
 are accurately known.

 EXPEEIMENTS IN LOBSTEK KeAKING. 
 
 Model of the house-boat laboratory and apparatus used in raising newly -hatched lobster 
 fry to the fourth, or lobsterling, stage (Scale, i inch to the foot) : 
 
 Young lobsters swim or float in the ocean for about two weeks after hatching. The 
 skin is shed three times during this period, and after each moult the lobster appears 
 in a different form. Immediately after the third moult the precarious swimming habit 
 is given up and the life at the bottom, with the characteristic habits of crawling, 
 burrowing and hiding, begins. The many attempts to protect the young lobsters 
 through this critical period have been thwarted by the peculiar difficulties of confin- 
 ing and feeding the fry, for in confinement they usually die from the effect of canni- 
 balism, starvation, suffocation, or parasites. 
 
 The principal object of this apparatus is to keep the fry and their food suspended 
 in the water by creating, with the paddles, a constant upward swirling current. The 
 machinery is run by a gasoline engine situated in one of the houses. From 16 to 50 
 per cent of the newly-hatched fry have been carried through to the fourth stage by 
 means of this apparatus. 
 
 The house-boat is the marine station of the Rhode Island Commission of Inland 
 Fisheries and is situated in Narragansett Bay at Wickford, Rhode Island. The experi- 
 ments in raising lobsters were conducted by that commission in collaboration with the 
 United States Fish Commission.

 Development of a Trout. 
 
 Models illustrating the early stages of development of a trout : 
 
 The fertilized egg is shown in model 1. The white portion represents the disk of 
 protoplasm which, by its growth and development, gives rise to the embryo. The 
 yellow portion, which is relatively large in the early stages, is the yolk, which serves 
 as food, and is gradually absorbed during the process of development. The first 
 marked change is the formation of a furrow which divides the protoplasm into two 
 masses or blastomeres, as shown in model 2. Each of these becomes divided by a cross 
 furrow, producing 4 cells, as shown in model 3, and subsequent divisions give rise to 
 8, 16, 32, and, eventually, numerous cells, as shown in models 4-8. During the later 
 stages of this process the protoplasmic matter has increased by the absorption of some 
 of the yolk, which becomes thereby relatively and actually smaller. The mass of cells 
 has become lens-shaped, its lower surface dipping somewhat into the yolk, as shown 
 in models 9 and 10, which represent sections of about the stages shown in models (i 
 and 7, respectively. 
 
 The mass of cells which has before been uniform now becomes differentiated into 
 two layers, and a cavity appears between the lower layer and the yolk. This is shown 
 in models 11 and 12, where the layers are indicated by conventional colors. Soon 
 after, a third layer appears between these two, as shown in model 13. These three 
 layers give rise to all the tissues of the adult fish, in general terms the outer giving 
 rise to the outer skin, brain, and sense organs, the inner or lower layer to the lining 
 of the alimentary canal and to parts of the related organs, and the middle layer to the 
 bones, muscles, blood vessels, etc. 
 
 As the protoplasmic portion or blastodermic disk gradually extends over the yolk its 
 edge becomes thickened and the body of the fish begins as a tongue-like growth inward 
 from a part of this ring, gradually extending over the disk, as shown in models 14-21. 
 The thickened folds shown in model 21 and several of its predecessors represent the 
 developing brain and spinal cord. 
 
 Subsequently the sense organs, alimentary canal, and other organs appear, the head 
 and tail of the embryo grow free from the now inclosed dwindling yolk, and at the 
 time of hatching the latter remains as a protuberant sac on the belly, furnishing 
 nourishment to the fry until such time as it is able to take food through its mouth. 
 
 Bacteria and Fish Pathology. 
 
 (Juliwres of bacteria from water and from the diseases of fishes: 
 
 This exhibit is designed to illustrate the Commission's work in a comparatively new 
 field. Bacteria are of chief importance in human disease, and it was to be anticipated 
 that they would play a corresponding part in lower forms. Some important affections 
 of fishes have been traced to bacterial infection, and several of the cultures shown were 
 made from the blood or tissues of diseased fishes. Notable among these are the bacillus 
 of tuberculosis in fishes, from a European source, this disease not having yet appeared 
 among fishes in this country, and Bacterium trutta?, a chromogenic organism which 
 recent investigations of the Commission show to be the specific cause of a destructive

 The principal pus cocci are also represented, among which the streptococcus is most 
 important, causing the " oyster hand," familiar in oyster regions, and arising from 
 wounds caused by " shucking " oysters or handling the shells. 
 
 A number of salt and fresh water bacteria are shown, including some handsome 
 chromogens. Some of these are also frequently found unassociated with water. The 
 commoner water organisms may be frequently obtained from tissues or regions of 
 fishes to which they have access.

 Plates illustrating some diseases and abnormalities of fishes : 
 
 Both wild and domesticated fishes are subject to parasitism and disease which 
 sometimes cause among them extensive and fatal epidemics, or are the normal 
 phenomena which terminate the life of the adults of certain species after spawning, 
 as in the Pacific salmons of the genus Oncorliynchus, but in most cases they are 
 sporadic and rarely fatal. 
 
 Owing to the crowding of the young in ponds, troughs and other circumscribed 
 waters, disease is more common and more fatal among fishes raised in captivity than 
 among those living in a state of nature, and malformations resulting from injury to 
 the eggs and young are more frequently observed, if not of more frequent occurrence. 
 The epidemics are usually due to bacteria, fungi and low animal forms, but some- 
 times great mortality arises from purely mechanical and chemical causes, notably 
 from a deficiency or a superabundance of air in water. 
 
 The following plates are exhibited to illustrate a few of the diseases observed in 
 wild and domesticated fishes : 
 
 Infectious disease in trout: Brook trout {Salvelinus fontinalis), showing the blood 
 extravasations and ulcers caused by Bacterium truttm. This disease is very destruc- 
 tive to domesticated trout, but is harmless to man. 
 
 Animal parasites of trout : Copepods, crustacean parasites, upon the gills of brook 
 trout. Occasional and seldom fatal. 
 
 Tumor : A tumorous growth protruding from the gills of a rainbow trout {Salmo 
 irideus). Occasional among domesticated trout; causes anemia and is usually fatal. 
 The specimen illustrated is from the government hatcheries of New Zealand. 
 
 Short gill covers : A malformation of the brook trout {Salvelinus fontinalis) exposing 
 the gills. Caused by domestication and unknown among wild fish. Seldom fatal. 
 
 Deformities among domesticated fishes : An adult brook trout (Salvelinus fontinalis), 
 natural size, deformed by mechanical injuries received probably before hatching. 
 
 Deformities among wild fishes: Young menhaden {Brevoortia tyrannus) with curva- 
 tures of the spine, caused by injuries or concussions during incubation of the egg. 
 
 The gas disease: " Popeye " in the scup {Stenotomus chrysops). A symptom of the 
 gas disease caused by an excess of dissolved air in the water. Gas has accumulated 
 behind the eyeball. 
 
 Pacific salmon during the spawning season: A male humpbacked salmon {Onco- 
 rhynchus gorbuscha) dying after the spawning season. Frayed fins, fungus patches, 
 and fungus ulcers. The Pacific salmon spawn but once, and then die a natural death, 
 The injuries and fungus attacks are incidents of and not the cause of death. For can- 
 ning purposes salmon are taken long before this stage.

 IV. APPARATUS, METHODS AND STATISTICS OF THE FISHERIES. 
 
 Model Illustrating Fishing Scenes on the New England Coast. 
 
 This model represents the five important methods employed in the capture of fish 
 and lobsters for commercial purposes by fishing vessels along the New England coast. 
 
 The gill net, set at the surface, is used for catching mackerel, herring, and other 
 fish that school on the surface. The mesh of the net varies in size from 1\ to 3^ 
 inches, and the vessel carries, on an average, ten nets to each member of the crew. 
 
 At the rear of the gill-net set at the surface is a trawl ; this varies in length and has 
 short lines with hooks fastened to it at regular intervals, the intervals varying from 
 3 to 15 feet, according to the fishery in which the line is used. In the haddock fish- 
 ery the hooks are 3 feet apart ; in the halibut, 12 to 15 feet. The trawl is set by 
 allowing it to sink to the bottom, the ends being secured by anchors, from which long 
 lines lead to the surface, where they are attached to buoys or kegs, so that the fisher- 
 men can locate the trawl. Each line of trawls is about 50 fathoms long and each 
 member of the crew has from 21 to 50 lines to fish, or from 1,500 to 3,000 hooks. Cod, 
 haddock, halibut, and pollock are the principal fishes caught by this method. 
 
 The purse seine is principally used for capturing mackerel, herring, and menhaden. 
 The average mackerel purse seine is about 225 fathoms and 1,000 meshes deep (2-inch 
 mesh), and costs from $500 to $800. It is set around a school of fish so as to form 
 a bag or purse, as shown by model. 
 
 The net set on the bottom illustrates the use of the gill net in catching cod, which 
 school near the bottom of the ocean. The fish are caught by passing their heads 
 through the meshes of the net. 
 
 The lobster traps are set on the bottom and show the method of catching lobsters. 
 In the background is Thatcher's light-house, north of Cape Ann. 
 
 U. S. Fish Commission Schooner Grampus (rigged model ; scale, \ inch to 1 foot). 
 
 The Grampus was designed by and built under the supervision of Capt. J. W. Col- 
 lins, U. S. Fish Commission. She was launched in the spring of 1886, and went into 
 commission on June 5 of that year. She is provided with a well, located in the 
 middle of the vessel, in which fish and other marine animals can be kept alive and 
 taken from distant fishing-grounds to the coast stations of the Commission for fish- 
 cultural purposes or to serve as objects of study and research for biologists. In other 
 important respects she is arranged and fitted to adapt her to carrying on the marine 
 researches and investigations which are being continuously prosecuted by the Com- 
 mission. Among other things, she has been fitted to operate a beam-trawl, to test its 
 utility, in a commercial way, in American waters. 
 
 The Grampus is a two-masted, schooner-rigged vessel, 90 feet long over all ; 81 feet 
 6 inches L. W. L.; 22 feet 3 inches beam, and 10 feet depth of hold. She registers 
 83.30 tons. An important object sought in her design was the production of a new 
 type of fishing vessel — one that will be much safer and in various ways better adapted 
 to successfully encounter the exigencies which must be met by schooners employed 
 in the ocean fisheries. In model and rig she is a radical departure from the vessels 
 commonly engaged in the New England fisheries prior to her advent, and her superi- 
 ority in safety, speed, and other desirable qualities has been fully established. After

 twelve years' service the Grampus is unexcelled in speed by fishing vessels or pilot 
 boats. She differs from the typical fishing schooner of the time when she was built in 
 being 18 to 24 inches deeper, in having 6 to 10 inches less beam, and an easier after 
 section. She has less proportional width aft, greater rake to stern, and pilot-boat 
 bow, with strait stem above water. Her extreme draft is 11£ feet. 
 
 The principal features of the Grampus have been copied by New England builders. 
 Nearly all of the fishing vessels recently built are deeper than formerly, and embody 
 other features that characterize the Grampus. The spirit of improvement has received 
 such an impetus that the best skill of the most eminent naval architects has of late 
 been devoted to designing fishing vessels. 
 
 Models of Fishing Vessels and Boats. 
 New England mackerel seining schooner (rigged model : scale, £■ inch to 1 foot) : 
 
 The schooner Senator Gardner, of Gloucester, Mass., was built in Essex, Mass.. in 
 1900, for employment in the summer mackerel fishery and in the winter frozen-herring 
 trade ; is a vessel of modern type, suitable for all branches of the fisheries, and is repre- 
 sented in the model all ready to start on a cruise, seine boat on deck and seine stowed 
 on deck, ready to be taken into boat on arrival at the fishing-grounds.

 The schooner Rob Roy, of Gloucester, Mass., was built at Essex, Mass., in 1900, for 
 employment in the market fishery, and is an entirely new model in fishing vessels, 
 called the " knock-about" type. She is an ideal market fishing craft, as she is easily 
 handled around the dories when out setting or hauling trawls, and is a smart sailer 
 and an excellent sea boat. The model represents a market fisherman as she appears 
 ready to go to sea ; dories on deck, nested right side up.

 1899, for Grand Bank cod fishing in summer and in the winter frozen-herring trade. 
 The model represents a fast and seaworthy vessel, ready to go to the Banks on a cruise. 
 She is under full sail, with dories turned up and secured on deck, and checkerboard 
 and oil butts in place. She illustrates the extreme type of Grand Banker, and is a 
 very easy vessel to anchor in a heavy sea. Carries 2,21)0 barrels of herring, and had 
 600,000 pounds of cod on her first Grand Bank trip.

 Chesapeake Bay oyster pungy (rigged model : scale, § inch to 1 foot) : 
 
 The schooner W. F. McKewen, of which this is a miniature, is a typical oyster 
 pungy of the Chesapeake Bay region, where hundreds of such vessels are employed. 
 She was built in 1865, and was engaged in dredging oysters for many years. This 
 type of fishing vessel has undergone little change in half a century. 
 
 A carvel-built, wooden, keel vessel, with moderately sharp, flaring bow, curved, 
 strongly raking stem, long head, sharp floor, long, lean run, shallow, square stern, 
 raking sternpost, flush deck, log rail except aft of main rigging where there is an open 
 quarter rail, rollers on rail amidships for dredge rope to pass over, typical schooner 
 rig. Model equipped with oyster dredges, winches, etc. 
 
 Length, over all, 68 feet ; beam, 20 feet 9 inches ; depth, 7 feet. 
 
 The builders at Baltimore and other ports on the Chesapeake began the construc- 
 tion of sharp vessels much earlier than elsewhere on the Atlantic coast, and oyster 
 pungies substantially like those used in the closing years of the nineteenth century 
 
LOUISIANA PURCHASE EXPOSITION. 31 
 
 were built as early as 1845 or 1850. Almost without exception these are keel vessels, 
 with tall, raking masts, long bowsprit, and high, narrow sails. They are swift, and 
 quick in stays. 
 
 New Orleans fishing lugger (rigged model : scale, 1 inch to 1 foot) : 
 
 Model of the typical lug-rigged boat, so extensively used in the fisheries from New 
 Orleans and vicinity by fishermen who are chiefly Italians or other natives of south- 
 ern Europe. This represents a carvel-built, center-board boat, half deck forward, 
 with wide washboards and high combing around the elliptical-sbaped cockpit, the 
 latter being fitted with hatches at cover, about two-thirds of its length from the for- 
 ward part. There is a cuddy forward, which is entered through an opening in front 
 of the mast. The boat has a graceful sheer, increased forward to a bow shape ; a 
 sharp bow, with concave water line and straight stem ; very shallow keel ; moderately 
 rising floor, with quick turn to bilge ; medium length of run ; V/- S haped, square stern, 
 with no overhang to counter ; rudder hung outside and moved by tiller. The rig con- 
 sists of a single mast, 12 feet abaft the stem, and on this is set a single large lug-sail, 
 which tacks to a traveler near the bow, where the sheave trims to an iron traveler 
 across the taffrail or at the stern. The sail is not dipped in making short tacks to 
 windward. Boats of this class are not used anywhere in the United States except on 
 the Gulf coast, and are restricted there chiefly to Louisiana. They are celebrated for 
 speed, and are reputed to be especially well adapted to the shallow, narrow waters in 
 which they have to work. 
 
 Length, over all, 40 feet 6 inches ; leDgth of water line, 39 feet 9 inches ; beam, 12 
 feet 6 inches ; depth, amidships, keel to top of gunwale, 4 feet 9 inches ; draft, aft, 2 
 feet 9 inches; forward, 1 foot 9 inches; length of mast, extreme, 45 feet ; length of 
 yard, 38 feet 6 inches. 
 
 Key West smackee (rigged model : scale, 1 inch to 1 foot J : 
 
 The welled fishing boat Jeff Brown, of Key West, Fla., of which this is a minia- 
 ture, was built for the market fishery at that port in 1883. Boats of this kind are 
 called " smackees," a variation of the term "smack" as applied to welled vessels. 
 They are employed in considerable numbers at Key West, and are noticeable for 
 having the " Mudian rig " — a leg-of-mutton mainsail and jib — and also a well in 
 which the fish are kept alive. 
 
 A wooden, carvel-built, sloop-rigged keel-boat, with good sheer ; sharp bow, rising 
 floor, long run and skag ; V-shaped, raking stern ; cockpit aft ; well amidships, cuddy 
 hatch forward ; mast stepped well forward ; short bowsprit. Length over all, 24 
 feet ; beam, 8 feet 3 inches ; molded depth, 3 feet ; mast, above deck, 32 feet ; bow- 
 sprit, outside, 6 feet ; main boom, 23 feet. 
 
 The majority of the Key West smackees are slightly smaller than the Jeff Brown, 
 and differ from the latter in having square vertical sterns, with their rudders hung 
 outside. They sail well and are reputed to be seaworthy and able in strong winds. 
 
 Connecticut oyster steamer (rigged model : scale, h inch to 1 foot) : 
 
 Model of the oyster steamer Jeremiah Smith, of New Haven, Conn. This vessel 
 was built in 1885, at West Haven, Conn., and is one of the largest and finest vessels 
 of this class, constructed for the special purpose of carrying on the oyster fishery in 
 Long Island Sound. The model is fitted With boats, dredges, etc. This vessel is 
 wide and rather flat, with moderately sharp bow and low, rounding bilge ; rather 
 short run ; large deck houses ; provided with rollers for operating the dredge ; side 
 chafing chocks, etc. The wheelhouse is above the main-deck house. The vessel is 
 fitted with a screw propeller, and will steam about 7 or 8 knots. 
 
 Gross tonnage, 113.38 ; net tonnage, 66.68 ; length over all, 72 feet ; extreme beam, 
 24 feet ; draft, 6 feet. 
 
 Market steamer Golden Gate (rigged model : scale, h inch to 1 foot): 
 
 The Golden Gate was built in 1891 for employment in the market fishery from San 
 Francisco, Cal. It is a representative of the type of small steamers of which several 
 have been built to fish from San Francisco with the parenzella. The building of 
 such vessels for the market fisheries of the Pacific coast was suggested by the U. S. 
 Fish Commission in an article published in 1888, entitled " Suggestions for the 
 employment of improved types of vessels in the market fisheries," etc. Sharp bow; 
 straight stem above water line, curved below ; moderate rise to floor ; long, lean run; 
 round stern ; strong sheer ; engine and pilot houses on deck; sloop- rigged, with loose- 
 footed gaff mainsail.

 The schooner Royal was built at Benicia, Cal., in 18111, and is owned at San Fran- 
 cisco. She is a representative of the type of small auxiliary steam schooners 
 employed in the Alaskan salmon fishery, and is noticeable for having pole masts and 
 a leg-of-mutton mainsail, which are characteristics of schooners fishing in Alaskan 
 waters. Long, sharp bow ; raking, curved stem ; rising floor ; medium length of run ; 
 overhanging, elliptical stern ; good sheer; fitted with deck houses; screw propeller, 
 and rigged as a two-masted schooner.

 Groatan Sound -fishing boat (rigged model : scale, 1 inch to 1 foot): 
 
 Sloop boats of this type are used in large numbers in the gill-net shad fishery of 
 Croatan Sound and adjacent waters in North Carolina. Many of them are built on 
 Croatan Island. They are well adapted to the shad fishery, being fine sailers and 
 easy to row. This is a wooden, carvel-built, open, centerboard boat ; long, sharp 
 bow ; rising floor ; long, fine run ; raking V-shaped stern ; good shear ; a single 
 mast ; loose-footed, sprit mainsail and jib, the latter tacking down to the stem head.

 Eel pot. 
 
 Wire eel pot : 
 
 Used by fishermen in Waquoit Bay, Massachusetts, in fishing in waters 6 to 9 feet 
 deep. Live minnows are considered the best bait. When live bait cannot be obtained , 
 fresh fish of any kind is used. The fish is suspended in the middle of the pot by a 
 string fastened to the "backbone" which runs lengthwise of the pot. 
 
 Wicker eel pot : 
 
 Used by fishermen at Vineyard Haven, Mass., and fished in water 8 to 21 feet deep. 
 Ballast of stones sufficient to sink the pot is used, the stones being put into both com- 
 partments. The bait is not suspended, but lies on the bottom of the pot. 
 
 Another pot made exactly like this, only from 5 to 7 feet long, is used in water 
 2 or 3 feet deep, generally in a narrow creek. No bait is needed with this pot, but 
 a leader and wings, made of sticks about 15 or 18 inches long and woven with rope, is 
 used. The leader is usually 20 to 40 feet long and each of the wings is about 20 feet 
 long. The pot when set as above really becomes a small weir. 
 
 Lobster pot (rounded top) : 
 
 This style pot has been in common use in southern Massachusetts a number of 
 years and is known as a " parlor pot." The style is peculiar (in having one end 
 closed) to the territory south of Cape Cod. The pots used north of Cape Cod have 
 a funnel in both ends, so that it is possible for a lobster to enter through either eDd. 
 The fishermen claim that the parlor pot is preferable, as many are lost through the 
 lower end of the double-end pot while it is being hauled to the surface. All the 
 lobster pots require ballast to sink them to the bottom. The average ballast per pot 
 consists of 8 bricks placed on the bottom of the pot and along the sides, and held in 
 place by laths along the sides tied with a string. This pot is fished in water varying 
 in depth from 10 to 200 feet. Fresh fish is considered the best bait, but when this 
 cannot be obtained salt bait is used. 
 
 Lobster pot (fiat top) : , 
 
 This is practically the same as the other lobster pot, differing only in shape. Fish- 
 ermen agree that these pots fish equally well, but are gradually discarding the rounded 
 top for the flat top, as the latter store better in a boat when being carried to and from 
 the fishing grounds.

 Model, of Columbia River Stationary Fish Wheel. 
 
 These wheels are used along the Columbia river from the falls at Celilo to a point 
 as far downstream as Corbett's Landing, Oregon. They are of two kinds — stationary 
 wheels like the model, and scow wheels. The latter are mounted on stout scows, from 
 which they are hung downstream by the aid of strong derricks or arms. The opera- 
 tion of the two kinds of wheels is the same, except that the scow wheels are towed 
 from point to point and anchored in places which seem favorable. 
 
 The wheels are usually placed where the shore juts out into the river, for at such 
 points the channel and current are most favorable to the ascent of the fish. In addi- 
 tion to placing the wheels on the points, they are placed in the gorges, where the river 
 is narrow and swift. When the salmon come into contact with the leads to the wheel 
 they follow the lead until they reach the wheel, where they are attracted by the large 
 volume of water which comes through. One " nib " of the wheel is constantly in the 
 water, and as the salmon swim up into it they are lifted from the water, and as the 
 wheel turns are thrown toward its axis, near which is placed a chute, and dowu this 
 they slide into the fish box or well. 
 
 The only attention that the wheels require is that they be guarded against drift; 
 that they be raised or lowered according to the rise and fall in the river, and that the 
 fish be taken from the well. * 
 
 The swift water in which the wheels usually work, especially if the drift be bad, is 
 hard on them, and they usually undergo extensive repairs every year. The wheel from 
 which the model was built is situated just opposite Cascade Locks, on the Washington 
 shore of the Columbia river. The cost of such a wheel is approximately $8,000. The 
 photographs show the original wheel and location, while the accompanying plan shows 
 a stretch of the Columbia river. 
 
 The winches on the model are used for lifting the trap to the fish well, lifting the 
 boxes of fish from the well, raising and lowering the wheel, etc. 
 
 These wheels at favorable times catch as many as 28 tons of salmon per day. 
 
 The dimensions of the original wheel are as follows : Height of gins, 95 feet ; diam- 
 eter of wheel, 52 feet ; width of wheel, 8 feet ; length of crib, 50 feet ; width of crib, 
 45 feet ; height of crib, 44 feet ; length of lead from crib to shore, 80 feet ; length of 
 lead from crib toward river, about 40 feet.

 Appliances foe Dredging and Seizing. 
 Oyster dredge : 
 
 Galvanized-iron frame 34 inches wide across mouth, with net of iron mesh. This 
 style of dredge is generally used all along the Atlantic coast, particularly in the Ches- 
 apeake Bay, on sailing vessels. 
 
 Oyster scrape : 
 
 Galvauized-iron frame 34 inches wide across the mouth, with bag of cotton netting 
 Used along the Atlantic coast of the United States on oyster beds in shoal water and 
 soft bottom. 
 
 Scallop dredge : 
 
 In common use in Buzzards Bay and the waters south of Cape Cod, Mass. It is 
 operated from a sailboat and is dragged along the bottom -while the boat is sailing, 
 thus scooping up the scallops. After the dredge has been dragged for a short time it 
 is hauled to the surface and the contents emptied into the boat. 
 
 Clam or quahog rake: 
 
 Used at Edgartown. Mass. When rigged it has a pole 20 to 30 feet long, so that the 
 operator can cover considerable ground without changing the position of the boat from 
 which he works. This pole is made of yellow pine and is 2 inches square at the end 
 joining the rake, and gradually tapers to 1 inch in diameter at the end. 
 
 Sea horse : 
 
 Used at Edgartown, Mass., for digging clams which are covered with water. The 
 canvas strap is passed over one shoulder and under the opposite arm, and enables the 
 operator to exert considerable force with his back and shoulders in addition to that 
 applied with his arms. The long teeth are forced down into the sand or mud and 
 then the whole is lifted clear of the bottom ; by a peculiar motion the mud and sand 
 are then sifted through, the clams being retained above the teeth and brought to the 
 surface.

 Model of the Florida Sponge Fishery. 
 
 The Florida vessel sponge fishery is prosecuted from small boats carrying two men, 
 each vessel being equipped with from two to six boats. While the boat is managed 
 and sculled by one man, the other, called the " hooker," watches the bottom through 
 a glass-bottomed bucket, the " water glass," which is held with one hand while with 
 the other he manipulates a long pole to which is attached a three-pronged hook. 
 When a sponge is seen it is detached from the bottom with the hook and drawn to 
 the surface. In the shallow water among the keys the water glass is seldom used and 
 but one man goes in a boat, which he propels with the sponge pole. About fifty 
 feet is the maximum depth at which sponges can be taken by means of " hooking." 
 
 The fresh sponges are killed by more or less prolonged exposure to the air and the 
 fleshy parts are macerated out in enclosures called crawls. The sponge of commerce 
 is merely the skeleton of the sponge animal. 
 
 The model shows the usual character of the bottom on which sponges are found 
 and the various operations of catching and curing them. A sponge sale with a group 
 of dealers is shown at the right.

 ■Improved breech-loading tonite hammer less darting-gun: 
 
 This gun is an improvement over the old breech-loading darting-gun No. 2 manu- 
 factured by William Lewis, of New Bedford. It is 17i inches long, seven-eighths of an 
 inch bore, and 'is as light as is consistent with strength. It is loaded from the breech 
 by unscrewing the barrel, and has been especially designed for Arctic whaling, but is 
 equally effective in sperm whaling. The materials used are the same as in the old 
 shoulder guns, but the lock case is entirely closed to prevent ice interfering with the 
 action of the lock, and it will discharge the bomb under water as well as out without 
 damage to any part of the gun.

 from the shank into the magazine, a nipple for the percussion-cap, an actuating 
 spriDg, and other appliances for releasing the cock, which are concealed in the 
 recessed head of the shank. The trigger, or lever-fluke, is fastened by a hinge-pin 
 immediately in rear of the lance-bomb. The action of the flesh as the instrument 
 enters the whale presses down the trigger or fluke in a line with the shank, and auto- 
 matically explodes and impels the head. Reloaded by substituting new heads. 
 Length, 4(H inches.

 The spear is attached to a pole 12 to 16 feet long, and is thrown into the back of 
 the turtle, the fisherman being in a boat. The turtle is drawn in and secured by 
 means of a line attached to the spear. By this method the turtle is badly injured, and 
 often dies from the effects of the spear wound, and cannot be shipped long distances. 
 
 Turtle-pegs : 
 
 A small pointed piece of steel or brass, called a peg, is loosely fitted into a brass 
 socket at the end of a 16-foot pole. Some pegs are 4-sided and others are rounded 
 
LOUISIANA PURCHASE EXPOSITION. 41 
 
 like the plug of a boy's top. A inarliue line is attached to the peg and runs to the 
 hand of the fisherman. The peg is wedged into the socket by means of a bit of cotton 
 cloth. When a turtle is seen in water up to 20 feet deep, the pole is hurled at it and 
 the peg enters the back shell, and holds fast ; the pole becomes detached and is sub- 
 sequently picked up, and the turtle is hauled in by means of the line. The peg enters 
 the shell one-half to 1 inch, and holds very securely, so that great force is sometimes 
 necessary in order to extract it. The turtle is not seriously injured and is available 
 for distant shipment alive, the slight bleeding being controlled by a pledget of tobacco. 
 Many tortoise-shell turtles, as well as green and loggerhead turtles, are taken in this 
 way about the Florida keys and reefs.

 Sponges. 
 
 Of the fishery products not used for food the sponges rank among the most 
 important, being extensively employed for various purposes in all civilized and many 
 barbarous countries. Florida is the only State on whose shores commercial sponges 
 are found. They are there taken in water ranging from a few feet to 50 feet in 
 depth, and occur in abundance throughout the Florida reefs and keys and on the 
 western coast as far north as St. Marks. The annual value of the Florida sponge 
 fishery is from $500,000 to $600,000, representing upward of 400,000 pounds of dry 
 sponges. 
 
 When first taken from the water the meshes of the sponges are filled with a pulpy 
 mass, aud the external surface is covered with a skin perforated for the. currents of 
 
LOUISIANA PURCHASE EXPOSITION. 49 
 
 water, on which the animal depends for its food and growth. Several natural sponges 
 are shown, preserved in alcohol. 
 
 The kinds of sponges recognized in the local sponge fishery and trade are sheeps- 
 wool, yellow, velvet, grass, and glove. The sheepswool. which is found among the 
 Florida Keys and in the Gulf of Mexico, is the best grade of sponge, exceeding in 
 value all others combined. It is used for a great variety of domestic and other pur- 
 poses, and "is the leading bath and toilet sponge. The average wholesale price per 
 pound received by the fishermen is $2.50 to $2.75. The yellow sponge, of which the 
 most valuable grade comes from the Florida Keys, ranks next to the sheepswool in 
 commercial importance. The average wholesale price is 60 cents to $1 per pound. 
 It is widely used for household purposes, and by painters, calciminers, wood workers, 
 aDd others for polishing and scraping. The velvet or boat sponge is of superior 
 grade, with a very soft texture, and is employed for the same purposes as the sheeps- 
 wool. It is not abundant, and brings about $1.25 a pound. The grass and glove 
 sponges are very abundant, but, being of inferior quality, they are only sparingly 
 used for the toilet. They are, however, extensively employed in livery stables, for 
 applying enamel and stiffening to fabrics, for absorbing oil in condensing tanks, and 
 for many other purposes. The glove sponges are worth only 15 cents a pound, and 
 the grass 30 or 35 cents, wholesale. 
 
 The artificial bleaching of sponges is a common practice and improves their 
 appearance, but unless very judiciously done is likely to impair their durability. 
 Bleached sponges of all the standard grades are exhibited in the collection. 
 
 glieepswool sponges from Gulf of Mexico : 
 
 The sheepswool is the best grade of sponge, and exceeds in value all other kinds 
 combined. The best quality comes from the grounds off the northern part of the 
 west coast of Florida. The present average wholesale price to the fishermen is about 
 .$2.75 per pound. This is the leading toilet sponge, and is also employed for many 
 other domestic and special purposes. 
 
 Sheepstoool sponges from Florida Keys : 
 
 The present average wholesale price received by the fishermen is $2.50 per pound. 
 This sponge is extensively used for a great variety of domestic and other purposes, 
 and is the leading bath sponge. 
 
 Velvet or boat sponges from Florida Keys : 
 
 A superior grade of sponge, with very soft texture. Valued at about $1.25 per 
 pound, wholesale, at the local sponge markets. Used for toilet and other domestic 
 purposes. 
 
 Fellow sponges from Florida Keys : 
 
 A valuable species, much used for domestic purposes and by woodworkers, painters, 
 and other artisans. The average wholesale price when first landed from the sponge 
 grounds is $1 per pound. The yellow sponges from the Florida Keys are superior to 
 those from grounds in the Gulf of Mexico. 
 
 Yellow sponges from Gulf of Mexico : 
 
 Somewhat less valuable than the same species from the Florida Keys. The average 
 wholesale price is about 60 cents per pound to the fishermen. 
 
 Grass sponges from Gulf of Mexico : 
 
 A cheap sponge, reaching a large size, and growing in great abundance on parts of 
 the Gulf coast ; it is used for the toilet and for numerous domestic and other purposes. 
 The average wholesale selling price to the fishermen is 35 cents per pound. 
 
 Grass sponges from Florida Keys : 
 
 This is a cheap grade of sponge growing in great abundance in Florida waters. It 
 is sparingly used for the toilet, and is also employed in livery stables, in condensing- 
 tanks to take up oil, for applying enamel and stiffening to fabrics, and for a large

 VI. THE AQUARIUM. 
 
 The purpose of the aquarium is to show (1) all the fresh-water and salt-water fishes 
 propagated and distributed by the Commission ; (2) all other important fishes and 
 other water animals of the interior, Great Lakes, and both Atlantic and Pacific coasts 
 which it may be possible to obtain and trausport; and (3) ornamental and curious 
 species of fishes and invertebrates of our fresh waters and coasts. The number of 
 different kinds of animals on exhibition at any one time is upwards of 100, and may 
 at times reach 150. The species are constantly changed, however, by the arrival of 
 fresh lots from all sections, mostly brought in the special railway cars of the Com- 
 mission. The central pool contains seals, sturgeon, large cat-fish, and various kinds 
 of turtles.
