TENTH ANNUAL YEAH BOOK— PART VI 21B 



For the iuformation of Professor Curtiss, I would say approximately 

 two per cent of cattle (other than dairy cows), five per cent of hogs, and 

 ten per cent of dairy cows, within the state of Iowa, are more or less 

 affected with tuberculosis.

 Mr. C. F. Curtiss, 



Iowa State College, 

 Ames, Iowa. 

 Dear Sir: — Replying to your inquiry in regard to tuberculosis among 

 hogs and cattle coming from Iowa to Omaha, regret to state that we 

 have no records as to where our hogs and cattle originate from. For 

 your information, however, will state that a trifle over one per cent of 

 our hogs is condemned for tuberculosis, basing it on six months or a 

 year's killing, and about three-quarters of one per cent of all the cattle 

 that we kill is condemned on account of the same complaint. 



Yours truly, 

 (Signed) M. R. MURPHY, General Superintendent.

 Omaha's receipts are Iowa hogs, but I should assume that Iowa furnished 

 a larger percentage of Omaha's total than they would of Chicago's total, 

 though I am not sure of this point. Yours truly,

From December 1, 1907, to December 1, 1908, we killed 616,198 Iowa 

 hogs. In this number of hogs, we are advised by the government in-
