~~ bovine animal in that district 
herd to which it belongs is recorded. It is impossible, therefore, for 
_. From January 1 to December 31, 1887, there were inspected in 
Maryland 5,704 herds, containing 57,858 head of cattle. Post-mortem 
_ éxaminations were made on 2,788 animals, of which 1,137 were found 
to be affected with pleuro-pneumonia. The total number of stables 
~ disinfected was 145. The number of animals affected with pleuro- 
_ ‘pneumonia slaughtered in Maryland since July 1, 1886, is 1,442, and 
of exposed animals (all slaughtered since March 3, 1887), 1,564, making 
-. a total of 3.006. The owners received from the Department as com- 
- pensation for the diseased animals $33,759.01, an average of $23.41 
_. per head; for the exposed animals they received $41,397.71, an aver- 
_ age of $26.46 per head. 
' The total expenses in Maryland in the work of suppressing pleuro- 
pneumonia from July 1, 1886, to December 31, 1887, were $105,853.81. 
Of this sum $75,156.72 was paid as rea an for slaughtered — 
cattle. The miscellaneous expenses, including disinfection, locks 
' and chains, tags, record books, etc., were $1,170.16. Traveling ex- 
. penses amounted to $9,430.49. The total amount paid for salaries 
- was only $20,126.44. The amount paid for cattle was to all other 
expenses as 1 to 0.41. | 
- Wehave, with the expenses in Illinois and Maryland, two extremes 
in the proportion of the amount paid for cattle to that paid for all 
- other purposes. The reason for the large relative expense for sala- 
— ries in Illindis has been given. The reasons for the small relative 
_ expenditures for salaries in Maryland are the large number of affected 
~ herds in Baltimore County, which made it easy to find great num- 
bers of affected and exposed cattle; the fact that the work of slaugh- 
tering has been continued without intermission, there being no 
period of investigation covered before the slaughtering began or after 
it was finished; the small size of the force, which for the most of the 
- time has been insufficient to properly control the movement of cattle. 
The last reason mentioned was due to the authority given by the - 
State not being sufficient to allow the supervision of the movement 
of cattle until after November 10, 1887, and, consequently, it would 
have been, a waste of money to increase the foree. Since the order 
of November 10 was made the number of men employed in Maryland 
has been largely increased, and the relative expenditure for salaries 
and other expenses will soon be greater than for cattle; but the effi-_ 
ciency of the work has been greatly improved, and the extirpation 
of the disease will cost less money than if the work were done with 
_- asmaller force. 
A relatively small expendtture for salaries is therefore no indica- 
.. tion either of the efficiency or the economy of the work for the sup- 
_ pression of pleuro-pneumonia. We might have gone on for years in 
_ Maryland with twice the expenditure for cattle that was made for 
-* all other purposes, but while the prevalence of the plague could have 
- been diminished the contagion could not have been eradicated. To 
accomplish this result, men.must be employed to watch the move- 
- ment of cattle, and to give permits by which they can be traced, to 
is numbered, and its number and the _. 
- the disease to exist in a herd for. any considerable time before its. 
ae : 
presence there is detected. 
_ » About all of the old infected herds have been destroyed, and the 
_ eases which are now found are due to recent infection. Such cases 
are becoming fewer, and it is believed that this decrease will continue 
and become more apparent with each month in the future.
