QUAER ANTINE. 3. No. 1. ANNUAL REPORT ON THE ST, LAWRENCE QUARANTINE SERVICE. GROSSE ISLE. • (FREDERIC MonTIZAMBERT, M.D., F.R.C.S., D.C.L.) Medical Superintendent. SIR,--I have the honour to submit this my annual report for 1889. The duties and responsibilities of the office which I hold have been enlarged this season. The inspection of the mail and other steamers at Rimouski—hitherto an independent service—was placed under my superintendence from the beginning of the season. The whole St. Lawrence quarantine service is thus rendered uniform as to administration under the one medical superintendence. This is in accordance with the recommendations made by Provincial Boards of Health and the visiting executive officers sent to inspect the service by the State Boards of Health of Michi- gan, Illinois and Minnesota. The inspection service at the Grosse Isle station has been continuously main- tained. The number of vessels inspected there has been 122 in excess of the number inspected last season. - - Infectious disease was reported by or found upon the following incoming vessels from abroad, named in the order of their arrival: Steamship “Montreal,” barque “Premier,” steamships “Circassian,” “Lake Superior,” barque “Asia,” steamships “Lake Winnipeg,” “Sardinian,” “Corean,” “Parisian,” ship “Lanarkshire”, barque “Daggry,” steamships “Corean,” “Alberta,” “Siberian " and “Grecian.” The diseases so reported or discovered were cholera, small-pox, typhus fever, yellow fever and measles. The season on the whole was a markedly healthy one. The admissions to the quarantine hospitals numbered only 32, out of 50,879 persons inspected. The steam tug “Champion” towed into the quarantine limits at Grosse Isle, on the 23rd of July, the ship “Lanarkshire,” with small-pox on board. The tug left her there and proceeded up the river without awaiting—as the law requires—the visit and permit of the inspecting officer. A telegram to Quebec, however, caused the “Champion ” to be met on reaching that city, and at once sent back to quaran- tine. Then the amount and circumstances of the exposure of the crew to infection from the “Lanarkshire’ were carefully investigated, and action taken accordingly. This is in accord with the law for tow-boats which have communicated with vessels liable to quarantine. As a rule it is carefully complied with by tow-boat captains and agents. This failure of the “Champion ” in the endeavour to evade it will probably prevent any recurrence of a similar attempt. YELLOW FEVER. The barques “Premier,” “Asia’’ and “Daggry,” allfrom South American ports, arrived at the Grosse Isle station infected with yellow fever. They were fumigated and disinfected. The question is sometimes raised whether there is any danger from yellow fever in this latitude and climate. An average temperature of 72° Fahr. is generally held to be necessary for the development of that disease. The mean temperature during the hot season in Quebec, and Montreal especially, during a “heated term,” is often higher than that which has been registered as the mean, whilst an epidemic has been at its acme in other places. In Spain and Portugal—which, like ourselves, have fre- quent intercourse with West Indian ports—yellow fever epidemics prevail from time to time. Thus Sternberg tells us that the city of Cadiz suffered in 1700, 1730–1, 1733–4, 1764, 1780, 1800, 1804, 1810, 1819–21. The epidemics of 1800, 1810 and 1819 were not limited to the city of Cadiz, but the disease extended to the interior, and caused a considerable loss of life in the Provinces of Granada and Andalusia, and also in some of the towns of Murcia and Catalonia, especially in Barcelona, from which city the disease was conveyed to the Island of Majorca during the last epidemic. Local outbreaks as a result of importation from the West Indies occurred in Gibraltar in 1828, Barcelona in 1870, and Madrid in 1878. An epidemic of the disease was inaugurated at Lisbon in 1856, and during the following year developed into a devastating Scourge, which extended to the towns of Belem, Olivaes and Almada. According to Hirsch, yellow fever prevailed to a limited extent at Quebec in 1805, and at Halifax in 1861. Vessels arriving infected with yellow fever have caused limited outbreaks of that disease in the ports of Plymouth and of Southampton. The same thing occurred at Brest in 1856, at St. Nazaire in 1861, and at Swansea (Wales) in 1864. The mean temperature of this last city at the time was only 67° Fahr. Coming down to this year (1889) an epidemic has occurred at Vigo, in Spain. In that city and the neighbouring coast cities nearly 1,000 persons were attacked. From 10 to 12 per cent. Of these persons are officially acknowledged to have died. From such facts as these it would appear that, whilst there may not be much danger of an epidemic of yellow fever in Canada, yet to allow our ship labourers to enter and work in the hold of a veseel infected with that disease, in any of our sea- ports in summer, might readily lead to at least a localised outbreak. So might also the landing, of infected clothing, &c. Acting on this belief, I do not allow any vessel with yellow fever cases on board, sick or convalescent, or reporting the occurrence of the disease on board, to pass the quarantine station until the atmosphere of her hold has been driven out by our steam fan, and she has been thoroughly fumi- gated and disinfected. CHOLERA. Asiatic cholera was reported by the S.S. “Alberta,” from Iloilo, Philippine Islands, with sugar for Montreal. She reached the Grosse Isle station on the 16th September. She had had two fatal cases of Asiatic cholera, and six cases of chol- eraic diarrhoea at Iloilo. As several vessels arrive annually in the St. Lawrence, and possibly others also at other ports, both of our Atlantic and Pacific seaboard, from Iloilo, Manilla and other Philippine ports, it may be mentioned that the Siglo Medico says, that between August, 1888, and July, 1889, 60,385 persons died of cholera in the Philippine Islands. The statistics being official, are pretty sure not to err on the side of € XCGSS. This same disease has also, this summer, spread from its East Indian home westward into Persia and Mesopotamia. At this present writing it is stated to be rather abating in the regions of the Tigris and the Euphrates, but still tending to spread westward. The number of choleraic deaths in the new region it has attacked registered from the end of July, the beginning of the epidemic, to October 25, reached 6,867. The following resolution referring to this matter was adopted at the recent annual meeting of the American Public Health Association, held at Brooklyn, in Octo- ber: “Whereas Asiatic cholera leaving its usual restricted bounds threatens to advance by the same lines that it has followed in the last four epidemics: be it Fesolved,—That the American Public Health Association desires to call renewed attention to this fact, and to urge that quarantine authorities on the Atlantic and Pacific seaboards and Boards of Health throughout the country make every effort to prepare for this threatening danger.” INFLUENZA. In this connection the epidemic of influenza, which is prevailing at present in Europe may be referred to, and the theory to which currency has been given in the telegrams from St. Petersburg, that epidemic influenza is a forerunner of cholera need only be mentioned in order that it may be condemned as unfounded. It is true that an infiuenza epidemic has on several occasions been closely followed by a visitation of cholera. But it is also true that there have been epidemics of influenza with no cholera following, just as there have been epidemics of cholera with no influenza pre- ceding. The two diseases are so dissimilar in causation and method of spread as to make any such sequence all but impossible. Any occasional instances of their simul- taneous appearance must be regarded as a mere coincidence with no deeper signi- ficance. Epidemic influenza seems to spread by the atmosphere, either by some peculiar condition of the air itself or possibly by micro-organisms carried in it and breathed into the lungs. It is thus that it can sweep over a country with such marvellous rapidity, and strike in one city 100,000 persons within twenty-four hours, as it is stated, to have done in Paris this autumn. Cholera, on the contrary— although the micro-organisms freed from dried excreta may be carried on the wind— spreads mainly by infected water, infected persons, infected things. It follows always along the lines of human travel. Against influenza spreading through the atmos- phere quarantines are useless. But cholera has never been brought to the American continent except on, and by, a ship. It therefore should be, and is, one of the dis- eases from which a country can be protected with certainty by efficient maritime Sanitation. AMERICAN PUBLIC HEALTH Association. At the meeting of the American Public Health Association above referred to, I had the honour to be present as your representative and delegate. Many valuable papers were read at this meeting, and the discussions on them, and on other sanitary subjects, were full of interest. The Association is a growing one. The importance of conjoint and co-ordinate work and protection against exotic disease by all parts of the continent is fully recognized by it. The following resolution was adopted at this meeting: “Resolved, that in view of the rapidly increasing commercial intercourse and trade between this country and Mexico, Cuba and the Central American States, and the consequent growing importance of establishing and cultivating the most friendly relations between the health authorities of our own and those of the countries above named, a cordial invitation be extended to the sanitary authorities of Mexico, Cuba and the Central American States to send representatives to future meetings of this Association; that the Secretary be instructed to open correspon- dence with the proper authorities looking to this end.” LEPROSY. The resolution urging preparations in case of the continuance of the present westward march of cholera has been already quoted. Another resolution was adopted requesting “Maritime quarantine officers to use the same vigilance and to hereafter enforce the same regulations regarding leprosy as are now pursued towards small-pox, yellow fever, &c.” OTHER QUARANTINEs. At the same meeting the reading of a paper by Dr. Wm. M. Smith upon “Improvements at the New York Quarantine Station ” was followed by the visit of the Association to the inspecting station and the quarantine islands in New York harbour. There, at Hoffman Island we had pointed out to us the new and com- modious dock, the new boiler house, kitchen, lavatories, dining rooms, dormitories, &c., and the, as yet unfinished, rooms for disinfecting by super heated steam, and at Swinburne Island the hospitals, officers' quarters, mortuary, and a crematory recently erected for the cremation of the bodies of those dying from infectious dis- ease. I was infomed that $150,000 have been expended upon these various works during the last season, and that about as much more would be required for their completion, The State of Touisiana is laying out and fitting up a new and enlarged quaran- time station on the Mississippi below New Orleans. It is to have a wharf with a frontage of 400 feet, with a minimum depth of water of 28 feet. On this wharf the cylinders for superheated steam, the tanks of mercuric chloride solution, and g - the fans, furnaces, &c., for fumigation with sulphur dioxyde, are to be placed. The last named appliance they find it well to take off their tug, even in the smooth waters of their narrow river. Charleston, South Carolina, has this season refitted her quarantine station with deep water wharf, with all the most modern appliances upon it. The Congress of the United States is now spending five hundred and forty-two thousand five hundred dollars ($542,500) in fitting up national refuge quarantine stations on the Atlantic and Pacific coasts with the newest appliances. Dr. Smith, the health officer of New York Harbour, in a report dated 1st Feb- ruary, 1889, says: “It is believed that the repairs and improvements of the quaran- tine establishment” (of New York) “now in progress and contemplated will supply all the conditions necessary to secure the country from any possibility of an epidemic of infectious or contagious diseases which approach by the sea.” This assurance from Dr. Smith is encouraging. '. An expenditure by the Dominion of Canada of one-half the sum that is being spent by New York would enable me to give a similar assurance as to the St. Law- rence. But as I have been reporting in season and out of season for the last twenty years, no such assurance can be given until the quarantine station at Gross? Isle is provided with a deep water wharf, upon which the modern appliances for prompt and scientific disinfection could be placed, and to which infected vessels could be brought for such prompt and scientific disinfection. VISIT OF PROVINCIAL BOARD. The Provincial Board of Health of Quebec paid an official visit to the Grosse Isle station on the 26th of September. The members present were Dr. Lachapelle President; Drs. Demieux, Garneau, Paquet, Craik, and the Secretary, Dr. Pelletier. They made a thorough examination of the Station and its appliances and workings. They were able to estimate the difficulties and delays caused by our present make- shift method of endeavouring to take the disinfecting appliances out on a steam yacht to an infected vessel in the offing. One vessel, I may here remark, was this season delayed for three days lying off the station. She was promptly inspected upon arrival, but had to wait for three days until the smaller disinfecting steamer could be used alongside of her for her fumigation. The Provincial Board subsequently issued in print a report of their visit. From that report I now submit a translation of some of its paragraphs: “The council is more and more convinced that the prolongation of the wharf, as it has already recommended to the Federal Government, is absolutely necessary, not for the inspection of vessels, which would continue to be done in midstream, but for cases where, after inspection, the entire vessel requires to be disinfected. Were this wharf built, vessels would be spared the long detention caused by landing passengers and their effects by means of yachts, as is now done. Moreover, the appliance Sfor dis- infection being then installed upon the wharf, and not on a yacht as at present, the disinfection would be performed more easily and more thoroughly, especially when the sea is high.” “The prolongation of the wharf, the installation upon that wharf of the appliances for generating sulphurous acid, as well as a large reservoir con- taining always in readiness corrosive sublimate in solution, and lastly, the con- struction upon, or close to the wharf, of an apparatus for disinfection by steam, are the great improvements which will make it possible to reduce the detention of vessels to a minimum, whilst ensuring the efficiency of the St. Lawrence quarantine; and the Provincial Council hopes that the Federal Government will recognize the urgency which exists of immediately supplying them at Grosse Isle.” |RIMOUSKI SERVICE. The Provincial Board also express in this report their satisfaction at finding that the inspection of the mail steamships at Rimouski has been placed under my super- intendence, and they add, “Recommendation que le Conseil Provincial avait déjà faite .au Gouvernement Fédéral.” Rimouski is the lowest point to which the Intercolonial Railway follows the bank of the River St. Lawrence. It is 180 miles below Quebec, and therefore about 150 miles below Grosse Isle. There the mail steamers and some extra steamers touch to land the mails, the passengers for the Maritime Provinces, and any others who may elect to continue their journey by rail. A Government medical officer boards steamships touching there. Thirty-seven steamships were so boarded this season. If the vessel is reported “all well” he allows the landing of the mails, and of such passengers as desire to disembark there, and gives the vessel a discharge from quarantine by a permit which exempts her from subsequently reporting at the Grosse Isle station further up the river, and which is in itself sufficient to procure her Customs' entry at Quebec or Montreal. If she be not “all well” he uses his dis- cretion as to the landing of anybody or anything at Rimouski. He may withhold a permit and send the vessel to Grosse Isle to be examined and dealt with there. The medical officer at Rimouski goes off to vessels in the mail tender. As that tender leaves again for the shore the moment the mails are transferred from the steamship to her, he has to depend very much upon the statement of the ship's surgeon, and has not time enough to thoroughly check that statement by personal examination. It was found that under this system infectious disease was, from time to time admitted into the country. - The placing of the whole quarantine system of the St. Lawrence under my superintendence was, as I have stated above, urged upon the Government by the Brovincial Boards of Health, and by the executive officers who were sent by the State Boards of Health of some of the western States to inspect that system. This has been carried out this season, and I have assumed, by your direction, these new duties and responsibilities. They entail, amongst other things, my going down by rail to Rimouski from time to time, and my coming up from that place on the mail steamers, inspecting them thoroughly between that place and Grosse Isle, an interval of about ten hours. My assumption of the medical superintendence of the whole St. Lawrence quarantine system ensures two beneficial results. First, there is uniformity of administration and method, and of the treatment of passengers and vessels throughout the service, and secondly, ship surgeons now never know on what incoming voyage they will find me coming off at Rimouski with the local inspector, to accompany them for the remainder of the voyage up the river, thoroughly investigating the exactness of their reports and the actual condition of the vessel whilst doing so. SHIPS SURGEONs. cº' Some ship surgeons are doubtless thoroughly reliable. But the status, remuner- ation, quarters, &c., and the fact that with few exceptions they have no tenure of office beyond the voyage, deter the better class of medical men, as a rule, from taking the position. My experience of this season has proved that where, from the necessarily hurried nature of the medical visit they alone expected at Rimouski, detection seemed improbable, some amongst them thought the saving of trouble to themselves and possible delay to the vessel of more importance than even the sanctity of an oath. For instance, in the case of one of the mail steamers I came up on, her surgeon took and signed the oath before Dr. Gauvreau and myself off Rimouski to the truth of his written statement that each of the steerage passengers on board had signs of having “been vaccinated within seven years, or of having had the small pox within that period.” After leaving Rimouski I made a personal examination of the steerage passengers, working in the steerage all day as the vessel continued her way up the river to Quebec. I found and vaccinated 198 persons not protected as the law above quoted requires. A large proportion of these were adults who made no pretence of having been re-vaccinated since their infancy; and seven were children, from four months to four years old, who had never been vaccinated at all. On several other mail steamers a similar condition of affairs was found to exist in varying numbers. Eight hundred and eighty persons in all were thus vºcinated ; ~ between Rimouski and Grosse Isle. '', I was further enabled by the detailed inspection thus secured to detect some cases of infectious disease in addition to those reported, and to carefully examine and suggest some needed improvements in some of the hospitals on these vessels. AA *** The effect of my extension of duty was quickly apparent. On the second and subsequent voyages I found that the ship's surgeons, not knowing on which occasion they might find me awaiting them at Rimouski, had performed their duties carefully and well. 3; There is every reason, therefore, to conclude that this extension of my duties has been productive of much benefit, and has removed what was a weakness and defect in the quarantine service. *} WACCINATION. The regulations as to vaccination were, on the whole much better obeyed by ships' surgeons this season. This was especially the case on vessels which had learnt by experience last year that these regulations would be faithfully enforced at the quarantine station. Only 1,059 vaccinations had to be performed at Grosse Isle this season, a marked reduction in number from the 4,000 of last year. The further number of 880 vaccinated on the mail steamers after passing Rimouski has already been given above. Passengers were vaccinated this year in varying numbers on the following vessels by your quarantine officers: S.S. “Parisian,” “Lake Winnipeg,” “Geo- graphique,” “Assyrian * “Henri IV,” “Nautique,” “Siberian,” “Grecian,” “Wan- couver’’ “Lake Huron " “Sardinian,” “Prussian,” “Carthaginian * “Dominion,” “Erik,” “Sarnia,” “Oregon,” “Lake Superior,” “Corean,” “Toronto,” “Lake Winnipeg,” “Canadian,” “Toronto,” “Norwegian,” “Nautique,” Corean,” and “Texas,” ship “Lanarkshire,” barque “Romulus,” and towboat “Champion.” Amongst these vessels the following were instances where individuals who had refused vaccination by the ships' surgeon, were induced by your quarantine officers to submit to it from our hands S.S. “Parisian,” “Lake Winnipeg,” “Assyrian” “Circassian,” “Lake Winnipeg,” “Canadian,” “Toronto” and “Norwegian.” Occasional passengers who preferred a quarantine of observation to vaccination were landed at the quarantine station from the S.S. “Oregon,” “Circassian” and “Parisian.” In the majority of instances under the last two paragraphs the objections were stated to me to be to the manner of procedure of the ships' surgeon rather than to vaccination itself. j WACCINATION REGULATIONs. With regard to the vaccination regulations in our quarantine laws, my experi- ence of their working during the last two seasons they have now been in force confirms the opinion I have already had the honour to submit, namely, that the great object to strive for is the securing of the vaccinal protection of passengers before the vessel leaves her port of departure. There is no general compulsory vaccination or re-vaccination law in Canada. Under these regulations the alternative of a quarantine of observation may be chosen. . It would seem, therefore, that the prevention of the introduction into Canada of vaccinally unprotected persons (who may contract small-pox after arrival) how- ever desirable it may be in itself is not the main object of the quarantine laws on this subject. The regulations requiring vaccination within a period of seven years, or a quar- antine of observation, have for their main object—as it would appear—the prevention of the entrance into Canada of any vaccinally unprotected person who may have been exposed to the infection of small-pox shortly before sailing for this country, or upon shipboard during the voyage, Lin other words who may have small-pox incu bating in his system. They are, I presume, founded upon some such considerations as the following:— (a). The period between the contracting of small pox and the falling ill with the decease—the period of incubation—is, as a rule, about twelve to fourteen days. That is longer by some days than the average steamship voyage from Europe to Canada A passenger may therefore take the Small-pox at his home on the continent or in England, on his way to the port of departure, or whilst there awaiting to embark, and yet remain apparently well during the voyage, and only fall ill with the developed disease after he has reached his inland destination on this side. An instance of this which occurred last year may be cited as an example. A passenger by the S.S. “Parisian * arrived at Quebec apparently quite well, yet, she was in the incubating stage of small pox, contracted in Norway or England, which developed in her a few days later in Minnesota, causing an outbreak of that disease. (b). The period of incubation of the protective vaccination is less than that of small-pox. A vaccination usually “takes’’ on the third or fourth day. By the eighth day the vaccine vesicle is completely developed, with its areola, the “Zone of safety.” -- (c). When this stage of the vaccine vesicle can be reached before the termination of the period of incubation of small-pox the attack of that disease, otherwise about to declare itself, may be averted. (d). Even when this stage of the vaccine vesicle is only reached after the actual appearance of the eruption of small-pox the attack of that disease may be modified or aborted. It is evident, therefore, that the earlier we can secure the vaccination of passen- gers, the more complete will be the protection for them and for this country. Vaccination during the voyage cannot be depended upon to prevent the develop- ment of small-pox from reception of its infection shortly before embarkation, unless it be performed the first day or two after sailing. If postponed by the ships' surgeon on account of other duties, or to allow the passengers to get over their sea-sickness, if only done late in the voyage, just to enable the ships-surgeon to make oath truth- fully that it has been done, or a fortiori if only done at quarantine at the port of arrival, it may modify the severity of the attack, but it cannot be counted upon to prevent its occurrence. My experience of the two years now last past, during which these regulations have been in force, has proved the well nigh invariable usage of ship'ssurgeons alike on our mail, and other passenger steamships to be the postponement of the exami- nation, and of such vaccination as they may do, until the steamship is in the com- paratively quiet waters of the Gulf—that is to say, until a day or two before the vessel is due at the quarantine inspecting point, the excuse usually given being that the recovery of the passengers from their sea-sickness had to be awaited. Per- Sonal observation has shown me that a very similar usage obtains on some at least of the principal steamships running to New York, and I am told by ships' surgeons generally, that it is practically the rule for all vessels bringing passengers from Europe to all ports on this side. The difficulty of examining and vaccinating a number of passengers suffering from sea-sickness, with all its attendant disturbance of mind and body, needs only to be mentioned to be believed in ; but it can scarcely be even approximately realized without having been experienced, It may be assumed, then, that this cause of the tardy examination makes the carry- ing out of the vaccinal protection during the first day or two of the voyage, practi- cally beyond the power of the ship's surgeon ; and, as before stated, when postponed until later, the vaccination cannot be depended upon to prevent the developºment of small-pox contracted before embarkation. - To secure the protection for Canada sought for by these vaccination regulations, every proposed passenger should be examined, and protection in accordance with them established or ensured, prior to admission to the vessel, or before she leaves the calm waters of the port of departure. The Government of England recognizes a duty to passengers leaving her shores, and to the countries for which they are so leaving her. In paragraphs 44 and 45 of the Imperial “Aet to amend the Law relating to the Carriage of Passengers by Sea,” it is enacted that, “No passenger ship, except as hereinafter provided (that is, where no medical man can be obtained), shall clear out or proceed to sea until some medical practitioner, to be appointed by the emigration officer, shall be satisfied that none of the passengers or crew appear, by reason of any bodily or mental disease, unfit to 10 proceed, or likely to endanger the health or safety of the other persons about to pro- ceed in such vessel. Such medical inspection of the passengers shall take place either on board the vessel or, at the discretion of the said emigration officer, at such con- venient place on shore before embarkation as he may appoint; and the master, owner, or charterer of the ship shall pay to such emigration officer a sum at the rate of twenty shillings for every hundred persons so examined. “If the emigration officer at any port shall be satisfied that any person on board or about to proceed in any passenger ship is, by reason of sickness, unfit to proceed, or is, for that or for any other reason likely to endanger the health or safety of the other persons on board, the said emigration officer shall prohibit the embarkation of such person, or if embarked, shall require him to be e-landed.” A person in the stage of incubation of small-pox is certainly “likely to endanger the health or safety of the persons on board.” Every vaccinally unprotected person embarking may be in that stage from recent exposure, consciously or unconsciously, to the infection, yet there being nothing is his appearance to betray his condition, it would not be discovered by this medical inspection. The enlargement of such medical inspection to include the examination as to the vaccinal protection of intended passengers, and the vaccination at that time—by the Government medical officer, by medical men employed for the purpose, or by the ship's surgeon—of all passengers who may not demonstrate previous protection within the required limit, would be the best means, and indeed the only possible and effectual means that I can see, of protecting this country from the developément after landing here of small-pox contracted before sailing. An occasional case might still occur on shipboard, where the person only embarked at a late stage of the period of incubation, but even here the vaccination if performed before sailing might modify or abort the attack. And from the protection of all others having been already secured, there would be no danger of the disease spreading on the vessels. Whilst by thus making sure of the vaccinal protection of all persons before sailing the great majority of the cases of small-pox now occurring on shipboard, and all those now occurring on, or just after, arrival at this side, would be prevented. I beg to most earnestly recommend this subject, and the expediency of endea- vouring to secure such vaccinal protection of passengers before sailing, to your favourable consideration. - RAG-WORKERs. . This disease, small-pox, is one of those to which rag-workers are exposed. In connection with this fact and referring to the difficulties so far experienced—as I have reported to you from time to time—in devising a mean of disinfecting rags in the bale, I may be permitted to cite here the rules issued by the Legislature of the State of Maine in a law entitled : “An Act to provide against the danger of the spread of Small-pox from Paper Mills.” “Section 1. No owner, agent, or superintendent of any paper mill, where domestic or foreign rags are used in manufacturing paper, shall hire or admit any persou to work in or about said mill who has not been successfully vaccinated or re-vaccinated within two years, or to the satisfaction of the local board of health. “Sec. 2. No person shall work in or about any paper mill where rags are used who has not been successfully vaccinated or re-vaccinated within two years, or to the satisfaction of the local board of health.” Sec. 3. The owner, agent, and superintendent in every paper mill where rags are used shall, every year, in the months of February and September, make out and deliver to the local board of health a list containing the names, ages, kind of work, and places of residence of all persons employed in or about said mill. “Sec. 4. In the months of March and October, annually, each and every person who is employed in a paper mill shall be examined by the local board of health as to whether he or she is successfully and sufficiently protected by vaccination, and the 11 -* local board of healthshall, in all cases, be the judges of the sufficiency of the protection by vaccination.” The violation of these provisions is made a misdemeanor punishable by fine. AMBULANCE. A new and very commodious and useful ambulance has this season been supplied to the quarantine station, Grosse Isle. It is used to convey sick from the wharf where they are landed, or from the western division, where “suspects” undergo quar- antine of observation, to the hosiptal. It replaces a worn-out ambulance waggón of obsolete pattern. It is a great improvement upon it in every way. It combines all the best features of the English, Scotch and continental models, with certain modifica- tions to meet the local and peculiar requirements of the station service. s SEARCH LIGHT. An electric search light for the inspecting steamer is much required. Wessels have to be boarded off Grosse Isle on arrival by night as well as by day. On dark and stormy nights this is often a matter of difficulty, not to say danger. On such nights the want of a search light has been much felt. The addition of such a light would greatly facilitate the prompt recognition and the boarding of vessels at night. It would also lessen the risk of injury by collision, or striking between the vessels. Such injury, for instance, as was mutually inflicted by your steamer “Challenger" and a Norwegian barque I was endeavouring to board in the gale of the 1st of June last. Moreover, amongst other advantages, the same engine and dynamo could sup- ply incandescent lights throughout the steamer, obviating the present ever-existing danger of fire from the coal oil lamps. For these latter reasons the small expenditure for this purpose would seem desirable, if only as a matter of insurance against the possible heavy expenditure to follow injury or loss. With regard to the steel cylinders required for disinfection by superheated steam, and other works and improvements of less importance at the station, I have had the honour already to submit recommendations for your consideration. DEEP WATER WHARF. The great deficiency and requirement of the quarantine station of Grosse Isle continues to be that of a deep water wharf. A wharf to which infected vessels could be brought to land their passengers and effects for disinfection; and on which could be placed the steel cylinders for the prompt and scientifically approved disinfection of clothing and effects by superheated steam, the elevated tanks for drenching with the mercuric chloride solution, and the steam fans, furnaces, etc., for changing the atmosphere in the holds and steerages and replacing it by one charged with sulphur dioxyde. I have already in this report quoted the opinion on this subject, officially published by the Board of Health of the Province of Quebec. And I have cited an example of three days lost to a vessel from the imperfect nature of our present make- shift appliances for want of a wharf. I can only repeat as I have done upon every possible occasion, that the deep- water wharf at Grosse Isle is the one essential, all-important, ever-pressing need of the St Lawrence quarantine service. Until that is supplied, and fully equipped as above, the service cannot be depended upon, nor be expected to protect the country from the invasion of epidemic disease. g I have the honour to be, Sir, Your obedient servant, F.
