THE RECENT CATTLE DISEASE IN KANSAS. 
205 
rival seven days later, the cicatrices in the mouths of two were 
still visible, but the temperature was normal and the feet showed 
no evidence of having suffered. The fact that these cattle were 
for a week subjected to the same causes that induced the disease 
in the original herd invalidates any theory of contagion in their 
case. To correct this four additional fresh cattle were placed for 
twenty-four hours in the same yard with the six, and then the ten 
cattle and six sheep were, April 11, placed in a small yard, built 
on to the fence of Keith’s corral and supplied with swamp hay, 
clear of ergot, corn in the ear, and well water. On April 14 
these four had temperatures varying from 103.3° to 103.8° Fall., 
and one showed a blush of the hard palate, tenacious mucus in the 
mouth, and a film of mucus on the feces. Next morning the tem¬ 
peratures were 103.3° to 104.3° Fall. On my first arrival, the 
same night, the temperatures were once more natural, and there 
were no lesions of month, feet, nor teats. After this they show¬ 
ed no symptom of illness. The sheep also had a natural temper¬ 
ature and no sign of lesion of mouth nor feet. 
Up to this point there was no more than a mere presumption 
of infection. The first six cattle experimented on, and which had 
the slight eruption in the mouth, had been subjected to conditions 
like those producing the disease in the original herd. These con¬ 
ditions were probably intensified, as the small yard in which they 
were confined was some distance from both pond and pump, and 
it seems fair to assume that water was not so constantly accessible. 
The exposure to these conditions was for a limited time, it is true, 
but their suffering was proportionally slight, and the presumption 
is quite as strong for the development of the disease from these 
conditions as from contagion. The second lot of four cattle had 
been subjected to these conditions for twenty-four hours only, 
and they suffered from digestive disorder with attendant fever, 
but this was quite transient and was unattended by any visible 
eruption. The sheep which escaped the inimical conditions in the 
first small yard, and were merely subjected to contact with the 
six diseased cattle, showed no evidence of disease, not even ele¬ 
vated temperature. 
While these experiments may, perhaps, be held to leave the
