388 ANNUAL BEPOKTS OF DEPARTMENT OF AGEICULTURE. 



OTHER WORK. 



Some work has been and is still in progress relative to breeding 

 hogs immune to hog cholera. The progress made in this work is not 

 encouraging, and does not hold out the promise that we will be able, 

 under the unsatisfactory conditions for work of the kind at the Be- 

 thesda station, to establish an immune strain of hogs. 



In cooperation with the other divisions of the bureau, and in the 

 line of supplying them with facilities, the following subjects received 

 more or less attention at the station: Tuberculosis, cattle ticks, dip- 

 ping experiments with cattle, dourine, swamp fever, rabies, black- 

 leg, parasites of sheep, disinfectants dangerous to animals, Malta 

 fever, forage infection and the effect of feeding fungus, Johne's 

 disease, hog cholera, tests of abortion, hemorrhagic septicemia, mange, 

 special tuberculin tests, etc. 



The usual quantity of blood, serum, milk, etc., and numerous small 

 animals were supj^lied for the use of the bureau laboratories. 



LOSS OF RENTED LAND. 



It is unfortunate that the bvireau will lose the use of a tract of land 

 near the station, comprising over 60 acres in area, which has been 

 held under lease for a number of years. This land was recently pur- 

 chased by a land-improvement corporation to be divided into build- 

 ing lots and tracts. This will reduce the amount of forage that can 

 be raised, and will considerably increase the annual cost for feeding 

 the animals kept at the station. While the 50 acres owned by the 

 United States at Bethesda are amply sufficient for the experimental 

 investigations of the station, it is desirable, for reasons of economy, to 

 have additional land because of the feed that can be raised on it at a 

 much lower price than we are obliged to pay dealers.
