Creek, which runs through the field. In the spring and early summer this land is over¬ 
flowed. The stock feed on the uplands until along in July, when the grasses dry out, 
-and then they go below to feed, where the grass is green. They soon begin to show 
symptoms of the disease. 
I think the germ of the disease is developed on the grass in the form of a parasitic 
fungus, due to fermentative changes which were produced by the long-continued moisture, 
followed by the extreme heat, the two great factors in any fermentative change being heat 
and moisture. There were about no head; n died, and when I was there they had 30 
head that were visibly affected—dull, listless in appearance, staggering gait, difficult 
mastication and deglutition, fever, pulse rate low, some were very stupid. The acute 
cases that died before I came would appear thus, then go down and delirium become 
extreme, and die without getting up again. The sub-acute cases were up and down, the 
extreme delirium not well marked, as they usually died quite quietly. In some of the 
cases the eyes were quite staring, and the eye was not affected when the ball was 
touched by the finger, reflexes being lost. The muscles of the tail had lost their tone, 
the tail being limp on manipulation. I put the animals on the enclosed prescription for 
the eight head in the barn, which were the worst; separated all the sick ones, and put 
them in a good meadow, where the hay had been cut off; the others, which’appeared 
well, I put in another upland pasture.

As the disease advances the animal will become more and 
more comatose ; standing" with all four limbs wide apart, and 
being moved up and down automatically as if walking, ^he 
delirium will recur at short intervals ; the animal will at times 
place the point of the sternum against the manger and in this 
position will push forward with all the strength of the body. 
More often the head will be placed against the barn wall and 
in this position the animal will push and batter its head until 
it is a sight to behold. The delirium may last for several days 
before death puts an end to the poor brute’s sufferings. Ani¬ 
mals affected with the disease will usually live from lo to- 30 
days, and in some of the milder cases they may linger on for 
several months. It is rare, even for the very worst cases, to die 
before the tenth day.
