Jt was the intention to remove all quarantine restrictions in Illi-- aia 
_ nois by January 1, 1888, but the frequent discovery of lesions in the eae 
_ -Tungs of slaughtered cows which, while not pathognomonic of pleuro- 
. pneumonia, might have been produced by it, led to the postponement 3 
of this action, On December 29 an undoubted case of chronic pleuro- wa 
' pneumonia, with encysted lung tissue, was discovered. From an in- oe i 
~ quiry which I at once made as to how this case could have escaped 
the general slaughter of exposed cattle that I supposed had been com- 
pleted, I learned that about 300 cows in the infected district had been 
_ allowed to remain, on the belief that they had not been exposed. . It 
was one of these animals, slaughtered by the desire of the owner, in «=~ 
_ the-presence of one of oui inspectors, which revealed the existence of Ay 
+ disease. The remainder of the herd was at once slaughtered and the aes 
_ stable thoroughly disinfected. The quarantine restrictions will now eR 
- be enforced until April 1, and in the meantime the remainder of the 
cattle that were in this district at the time the malady prevailed will les 
' beslaughtered, and it is hoped in this way to prevent any further 4 
extension of the quarantine. 
From January i to December 31, 1887, inclusive, 7,411 herds and 
_ premises were inspected in Cook County, Il., containing 24,059 head 
of cattle. Post-mortem examinations were made on 7,267 animals, 
_ which were either slaughtered or had died from disease, and among 3 
- these 350 were found affected with pleuro-pneumonia. The total Lie 
- number of cattle slaughtered in Illinois during this time, for which — 
~ compensation wasmade by the Department, was 1,042. Of these, 172 °° © 
- were diseased, and the owners received for them $3,179.53, anaverage 
of $18.42 for each animal, and 870 were exposed and the owners were | + 
paid for them $14,153.21, an average of $16.27, The average com- cha 
_ pensation for the exposed animals is less than for the diseased, for 
he reason that the value of the carcass was paid by the butcher to erie 
_ the owner, and this amount was deducted from the appraisement, x: 
_ and the owner was paid the difference as compensation from this De- i 
~ partment. ya; 
There were disinfected in Cook County during the year 677 stables; 
Some of these were very large, and the work required the constant — 3 
' labor of the disinfecting corps of eight men, The method of disin- 
_ fecting was to first thoroughly clean the buildings, removing all litter, Sey 
- manure, loose earth, and rotten wood, and then to cover with a mixt- re 
ure of chloride of lime and whitewash. This was applied by means 
of a powerful force-pump, worked by the members of the disinfecting 
corps. ae 
. The total expenses in Illinois on account of this outbreak, from aya) 
about September 1, 1886, to December 31, 1887, were $73,991.96. Of 9.) 
~ this sum, $17,552.74 was paid as compensation for slaughtered cattle. 
_. Miscellaneous expenses, including disinfecting material and appa- 
' ratus, tags, and ringers for inserting the same, record books, calc 
» rent, etc., amount to $3,952.52. Traveling expenses of inspectors and 
~ other employés, a part of which was for investigating reported out- 
breaks of disease in the country for a considerable distance around 
' Chicago, amounted to $3,598.99. The remainder was paid for the 
_ services of the inspectors, deputy sheriffs, disinfecting corps, and for 
clerical assistance in the office, amounting to $49,107.71. The amount 
if , paid for cattle was to all other expenses as 1 to 3.3.
