26 CONTAGIOUS DISEASES OF DOMESTICATED ANIMALS. 



The cattle on this farm were divided into two lots, which were in ad- 

 joining inclosnres, and were separated only by rail fences. The second 

 lot contained 40 two-year-old steers, purchased about November 1, and 

 was free from disease until February 28, though some of these had 

 broken through the fence at times and mingled with the diseased part 

 of the herd. March 10 about 10 or 12 animals in the second lot were 

 sick. Three days later Dr. Trumbower found 2 that would lose all four 

 feet. At this time there were 118 head of cattle on the farm, of which 

 74 were more or less affected. Nine animals had one foot off, 4 had two 

 feet oft', 1 four-j'ear-old cow lost both hind feet and a toe from one fore 

 foot, 3 others were affected in but one foot, 6 in two feet, and 1 in three 

 feet. In nearly all that showed lameness there were more or less mouth 

 symptoms. 



Across the road, and nearly opposite to Mr. Keith, lives Edward Hind- 

 man. It was here that the cattle belonging to A. C. Goodrich were lo- 

 cated. The 10th of March this herd numbered 96 head. The first 

 animal affected was a milch cow, noticed to be lame January 10. No 

 other cases occurred until February 14 or 15, when one v^as seen to be 

 lame in the morning after a heavy ice storm. The following morning 

 16 were lame. After that he disco veered new cases almost daily, aud on 

 March 14, when they were separated from the well ones, 65 head were 

 affected. March 19 the most sev^ere cases were as follows : 18 animals 

 had lost both hind feet, 5 had lost one hind foot, 1 had lost both hind 

 feet aud one fore foot, and 1 had lost all of its feet. Seven of the others 

 were lame in the hind feet, and the remainder of the 65 head affected 

 were more or less lame. 



In each of the above-mentioned herds the sick animals at the time of 

 my visits, March 19 and 22, had small erosions of the mucous membrane 

 of the mouth, and 2 or 3 had hard yellowish crusts in the same situa 

 tion an inch or more in extent. In no case were these sufficient to in- 

 terfere with mastication. This lesion was more noticeable in the old 

 chronic cases than in the recent ones. 



The third herd which contained diseased animals was located about 

 2^ miles from those already mentioned. It belonged to J. W. Beard. 

 This herd containt^d 70 head of animals, and 3 cows and 2 steers are 

 all that have been affected. All had been running together until the 

 disease was noticed, when the sick were separated from the well The 

 first syini>toms were observed on the 17th of February, when a cow was 

 seen to he lame. The second one to go lame was a cow bought of Mr. 

 Keith and brought to the farm February 18 — she became lame about 

 the 22d or 29th, accounts diftering between these dates. The third one, 

 a steer, became affected March 1. The fourth was a cow observed to 

 be sick March 1 or 2. It is reported that she slavered very profusely. Mr. 

 Beard states that he examined her mouth and found it very red and the 

 tongue covered with little })imples. At ten o'clock next morning she 

 died. This animal had not been lame. The fifth one was taken about
