SIR: I have the honor to submit herewith the Second Annual Report of the Bureau of Animal Industry, containing an account of the work during the past year for the suppression of the disease known as contagious pleuro-pneumonia of cattle, and also of the investigations of this and other diseases of our domestic animals, and in regard to the pres ent condition of the cattle industry. The outbreak of pleuro pneumonia in the Western States, which orig. inated in Ohio in 1883, and which at one time threatened irreparable injury to the cattle industry of the nation, has now been practically suppressed. The disease was carried from Ohio to Illinois, and from Illinois to Missouri and Kentucky, great damage being done by the interruptions of trade and commerce which resulted. The loss of cartle was less than would be expected from an outbreak of such proportions, and this was due, not to any diminished virulence of the disease, but to its early discovery and the measures adopted for its control and eradication. The part taken by this Bureau in the discovery and extirpation of the outbreak will be understood from a perusal of the present and the preceding report. Since the report was written information bas been received that the bill which has been pending in the Kentucky legislature for the extirpation of pleuro-pneumonia in that State has become a law, and it is now only a question of a short time when all danger there will be removed. This makes a period of about twenty months from the discovery of the plague in the West to its complete suppression, during which time the loss from restrictions and interruptions to trade have amounted to millions of dollars-probably to four or five times as much as would have been sufficient to extirpate this exotic disease from the whole country. With proper laws the malady could have been just as effectually extirpated within a few weeks and at an expense not exceeding $100,000. For the fortunate termination of this outbreak the country is indebted to the prompt and efficient co-operation of the authorities of the infected States, and particularly to Drs. M. R. Trumbower, C. B. Michener, and W. H. Wray, inspectors of this Burean, whose professional knowledge 5 |
