EXPERIMENTAL FARM. The work of the experimental farm 

 has progressed very satisfactorily in so far as the experiments con- 

 cerning the vaccination of cattle against tuberculosis are concerned. 

 It is important that other subjects shall be taken up and if this is 

 to be done in connection with the work that is now in progress 

 more accommodations for animals will be necessary, more buildings 

 will be required and more pasture land. With a comparatively 

 little increase in this direction as contrasted with the need for and 

 the value of the work several other subjects that should be in- 

 vestigated can be taken up. It is not possible, for example, to study 

 abortion, calf cholera or infectious garget in connection with the 

 present herd because all of these diseases jeopardize the offspring, 

 and it is necessary, in connection with our tuberculosis vaccination 

 work that young animals shall be produced and raised. Therefore, 

 if these diseases are to be studied, such studies must be made upon 

 separate animals, maintained entirely apart from the present herd. 



Some experiments on the breeding of animals are being considered 

 in connection with the cattle that are used in the experiments on 

 tuberculosis. If it is decided that such exi>eriments would be likely 

 to be instructive and important, and if they can be carried on in- 

 cidentally with the other work it would appear to be wise to 

 undertake them. 



The kind of information that this farm and the laboratory of 

 the State Livestock Sanitary Board are maintained to produce is 

 needed upon every farm and by every farmer in Pennsylvania. 

 Individual farmers cannot afford, nor have they the equipment that 

 would make it possible for them to conduct the researches through 

 which relief may be had. Their situation is quite different from 

 that of a corporation that is in position to employ exjjerts to help 

 it. And so governments of all countries have recognized this need 

 as it applies to the individual and the country at large, and have 

 taken steps to meet it, as here contemplated. 



GLANDERS. This disease has attained considerable prevalence 

 in Pennsylvania, not so much as a result of spreading within the 

 State, but from repeated introduction from outside of Pennsylvania. 

 It is well known that glanders prevails extensively in some of the
