PLEURO-PNEUMONIA. 
against this State, or the State itself takes some action for the 
suppression of the disease within its borders, the State of Pennsyl¬ 
vania cannot hope for success. The farmers of Pennsylvania will 
go to the Baltimore stock yards to buy “ frames ” and in this way 
new cases are continually being brought into the State. Under 
the present construction of the law sufficient means to pay a fair 
idemnity cannot be obtained, and to kill even diseased animals 
without funds to pay for them, the Secretary believes would result 
disastrously, as it would prejudice the farmers against a better 
law which is hoped for in the near future. His policy is simply 
an effort to keep the disease within its present limits, with the 
destruction of as few animals as possible. Up to January 1, 
1880, the Secretary had expended but $2,700 in repressive 
measures. 
On February 28, while examining some cows at the stock 
yards, I found an acute case of contagious pleuro-pneumonia. 
T1 le affected animal was in a yard with some twenty other milch 
cows, and all were being offered for sale. This animal was seen 
also by Dr. Bridge. On March 1, while examining lungs of 
slaughtered animals at the Philadelphia abattoir, I found one 
showing the well-marked lesions of the plague. The butcher 
said the animal came from Illinois, but it was afterward traced 
to Cecil County, Md. On the 2d day of March I visited Cam¬ 
den and learned some facts relative to the extent of the plague in 
New Jersey. On the 3d inst. I attended a meeting of the farm¬ 
ers and stock raisers in the infected district. The meeting was 
held in Philadelphia and was called for the purpose of devising 
means for the extirpation of the plague. During the day visited 
Elm station, Montgomery County, and assisted in selecting six 
diseased animals from Mr. Wynne’s herd, for the purpose of post¬ 
mortem examination. On the 4th and 5th days of March I was 
engaged in examining lungs of slaughtered animals at the Phila¬ 
delphia abattoir. I found no traces of the disease, but on the 
4th inst., while examining some cows at the stock yards, I found 
a second case of the plague in an animal that came from near 
Gettysburg, Adams County, Pa.
