lesions which presented themselves led me to think that there 
was some intestinal disturbance; I considered that the food was 
not at fault, the sanitary conditions could not be bettered, so I 
pronounced the trouble to be some specific hog disease. At my 
suggestion fewer hogs were kept, in order to see what changes 
might be wrought. Mr. F. raises now 4 or 5 hogs and has no 
trouble. He feeds as before. 
Mr. M., a wealthy farmer in our district, keeps from 80 to 125 
hogs. He, too, gathers swill from hotels and lake transporta¬ 
tion companies. The disease worked terrible havoc with his 
flocks. The sanitary conditions of his buildings are not even 
to-day good. I have worked hard in his herds, for he asks me 
to take full control of his yard, to do as I like with sickly ani¬ 
mals. We change pastures and feed with gratifying results for 
a time ; these changes seem to wear off and death repays us for 
our efforts. I believe to-day that this man will be obliged to 
keep fewer hogs in order to rid his herd completely of this dis¬ 
ease. Pardon me now if I step farther, possibly a step too far. 
We think we are breeding immune animals. The sows which 
survived the disease, and they are very few, are considered 
proof against the disease. They are bred, and rumor says the 
young will not take the sickness. I believe there is something 
in it. Very few animals die now in this herd, but, if a new 
hog is bought and exposed with the others in the herd, even if 
none of them are sick, he will take the disease and die. 
In 1897 an outbreak of this trouble occurred in Keeseville, 
a neighboring village. The herd belonged to a hotel man who 
fed slops from the kitchen as well as other foods from the farm— 
good food, I considered. They were herded in the basement of 
a large barn into which manures were thrown. They exer¬ 
cised in a large paddock adjoining the barn and on a hill-side. 
The animals had abundance of air and light, a dry place to 
sleep in, although they might lie and root among manures. 
About 40 young and old animals made up this herd. When 
they began to die I was called. I made a few post-mortems, 
killed a few sickly ones. I recognized our hog troubles at
