SIR: I have the honor to submit herewith the Third 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 or lung plague of cattle, and also of the investigations of this and other diseases of our domestic animals, and in regard to the present condition of the animal industry of the United States.

Since writing my Annual Report for 1885, the outbreak of pleuropneumonia which began in Harrison County, Kentucky, in 1884, and which was allowed to continue there until March of this year, has been entirely suppressed. This would not have been possible except for the act of the legislature authorizing the condemnation of the affected animals and providing compensation for them, and the cordial co-operation of the State Board of Health with the representative of this Bureau. All of the exposed animals were slaughtered and deeply buried, the stables and yards disinfected, and the locality kept under supervision until all danger of a re-appearance of the disease was past. Dr. W. H. Wray deserves much credit for the professional skill and business capacity shown by him in the management of this outbreak, which for many reasons was unusually difficult to control.

The most important event of the year was the discovery of pleuropneumonia among the cattle kept in the distillery stables of Chicago, and later among the cows pasturing on the commons of that city and some of the surrounding towns. The disease had existed there for a considerable time, and for this reason its origin could not be definitely ascertained. There can be little doubt, however, that it is a continuation of the 'outbreak of 1884, at which time herds were affected at Elmhurst, Saint Charles, and Geneva, either place being sufficiently near to account for the extension to Chicago. As a considerable number of cattle were exposed at Geneva, where a strict quarantine could not be maintained at the time, it seems most probable that the contagion was carried by cattle going from there to Chicago. The existence of such a dangerous plague in this great commercial center, and so near to the Union Stock Yards, through which cattle are passing to all parts of the country, is a menace to
