ver firm, who informed us that it came from that district. The animals 

 shipped for this determination received no treatment other than or- 

 dinary care and got no other food than the hay. Abundant water was 

 given. 



Following is a detailed account of these cases : 



Case 2)2i- — ^^d. heifer, i year old; raised at Jefferson, Colo., altitude 9,500 feet; 

 arrived at Fort Collins on January 13, 1915. Was very dull, listless; the brisket was 

 somewhat swollen; the abdomen was greatly distended; diarrhea profuse; irregular and 

 rapid heart; respiration rapid and difficult, with grunting. An occasional moist 

 cough was noticed. 



She was hauled to the Station stables and given South Park hay and water. She 

 ate not to exceed 5 pounds of hay during the next seven days, her appetite being prac- 

 tically gone (PI. 28, C). She gradually grew worse and died on January 21. The post- 

 mortem examination revealed typical lesions of brisket disease. 



Case 34- — A calf 6 weeks old was shipped on February 13, 1915, by express from 

 Jefferson, Colo., altitude 9,500 feet, arriving at Fort Collins on the 14th. He was in a 

 moribund state on arrival and died on the night of the 14th without eating anything 

 after being delivered at the Station. 



Case 35. — Red-and-white male calf, 6 months old, shipped on March 22, 1915, by 

 express from Woodland Park, Colo., altitude 9,000 feet. The calf had been ill for 

 two weeks previous to shipping. The owner had lost foiir others with the same trouble. 

 On arrival at the Station he was thin in flesh, and weak but not dull; tlie brisket was 

 slightly swollen, and the abdomen was enlarged. His appetite was good, and the 

 feces were normal. On South Park hay and water he gradually improved, so that on 

 the 27th the brisket became normal and on the 29th the abdomen had returned to 

 usual size. In all respects the calf was normal, except that he was thin in flesh. He 

 was kept tmder observation for two or three months, became fat, and finally was sold. 



Case 38. — A 4-months-old heifer calf; shipped from Jefferson, Colo., and arrived 

 at Fort Collins on October 3, 1915. She had a rather severe diarrhea, but there was 

 no swelling of the brisket and not much enlargement of the abdomen. She was placed 

 on South Park hay, but, as she would not eat it, alfalfa was substituted for two days, 

 after which she was given the South Park forage. Diarrhea continued for six days, 

 when the feces became normal, and the calf improved so that she was sold on Novem- 

 ber 2, 1915, in good condition. 



Case 39. — Hereford heifer, 6 months old, shipped to Denver from Jefferson, Colo., 

 and arrived at the former place on October 11. When seen on that day, she was very- 

 dull, the brisket were badly swollen, and she was grunting with each breath. Her 

 appetite, however, was good. She remained in Denver until the i8th, when she 

 was shipped to Fort Collins, arriving there on the 19th. The brisket was still swollen, 

 although much reduced. She was placed on the South Park hay and continued to 

 improve, so that on October 23 the swelling had entirely disappeared. She became 

 normal and was sold on November 2. 



Case 40. — Yearling Shorthorn steer; shippe'd to Denver with the preceding case. 

 Quite thin; had diarrhea, but no swelling of brisket. Arrived in Fort Collins on 

 the 19th, was placed on South Park hay, improved rapidly, and was sold in normal 

 condition on November 2. 



Case 41. — A 2-year-old Hereford steer; shipped with cases 39 and 40 and treated 

 in the same manner. This steer was very thin, had a diarrhea, and was scouring 

 badly. He gradually improved on the South Park hay, but did not put on much 

 flesh tmtil spring. He gained in strength, and the scoiuing stopped at about the 

 tenth day after arrival at the Station. In March he was sent to pasture, and there 

 died of tympanites on March 29.
