PLEURO-PNEUMONIA. 
Ill 
Returning to Baltimore on March 7 iu company with Dr. 
Daniel Le May, a veterinary surgeon, I visited a herd of milch 
cows kept in a dairy in Woodbury, near Baltimore. Here we 
found one acute and two chronic cases of the plague. The man 
in charge said that he had got through with the disease, from 
which he had suffered greatly some two months ago, by selling 
out all his sick animals. From here we went to another large 
dairy in the same neighborhood. The gentlemanly owner here 
informed us that he had had none of the disease for some 
time; that his plan was to buy often and • sell often. In this 
way he found he could keep up his milking stock and keep rid 
of disease. From here we visited a near neighbor living on the 
direct road to the city. In answer to questions this man said 
that he did not know if his neighbor (the one from whom we 
had just come) called it having the disease or not, but that he 
drove many a sick one past bis house on his way to the Balti¬ 
more market. He (our present informer) was free to say that 
he followed the same practice himself, and had done so ever 
since he lost his first eight animals. He supposed this was not 
right, but his neighbors did it, and so he did. Summer was 
invariably the worst time thereabout. The next place visited 
was about two miles distant and on a different road. The dairy¬ 
man here had suffered greatly in the past, but thought that now 
by selling the sick ones he had nearly rid himself of the plague. 
March 18.—We drove in several directions around the city 
and found the disease, or its effects, in all the herds except one 
that we visited. 
March 19.—To-day we examined a nnmber of the cow 
stables in the city itself, in which many chronic and a few acute 
cases were found. 
March 22.—I went to Harford County, where the disease 
was reported as existing in a number of different directions. 
However, we concluded to visit the farm of Senator George A. 
Williams, whose herd of fine Alderneys have been suffering 
more or less from the scourge for the past two years. Here 
among several chronic cases was one that, although he had been 
sick for some time, was making no progress toward a good recov-
