on a different farm; the stables were whitewashed and disinfected and 

 every precaution taken to prevent the spread of the disease to other 

 herds, and so far as we have been able to learn no aDimals in the 

 vicinity of his farm have contracted the disease. An examination of 

 his herd revealed the fact that a number of animals still showed posi- 

 tive evidence of lung disease. An effort was made immediately to raise 

 sufficient money to purchase and slaughter the affected animals, but the 

 discovery of another affected herd in the State destroyed all hope of ob- 

 taining sufficient funds for the purchase of all the diseased animals and 

 thus freeing the State from the disease. Mr. Dye, however, was anxious 

 to get rid of the disease in his herd, and consented to have those ani- 

 mals slaughtered which presented the plainest signs of the affection 

 on condition that the State board of agriculture would recommend the 

 granting of compensation at the next sitting of the legislature. 



September 19 I selected seven animals which presented signs of lung 

 disease, and these were appraised and slaughtered. The following is a 

 brief statement of the post-mortem appearances: 



No. 107. — Nearly all of the surface of the right lung attached to the 

 ribs and diaphragm. The lung was one large cyst, in which the hepa- 

 tized tissue was nearly all disintegrated and broken down into pus. 



Bull. — Eight lung adherent to ribs and diaphragm. A cyst 3 by 4 

 inches in diameter contained hepatized lung tissue badly broken down. 



Sylvie. — Posterior portion of the left lung atrophied with fibrous de- 

 generation and adherent to ribs and diaphragm. 



No. 145. — Left lung adherent to ribs and diaphragm, encysted mass 

 four inches in diameter containing disintegrated lung tissue. 



No. 114. — Left lung slightly adherent to diaphragm and ribs, weigh- 

 ing 12 to 14 pounds, containing encysted mass of eight inches or more in 

 diameter and weighing 8 to 10 pounds. 



No. 142. — Both lungs adherent to diaphragm and ribs, atrophy and 

 fibrous degeneration of one-third of left lung, two small and encysted 

 masses of dead lung tissue. 



No. 41. — Right lung largely adherent, atrophied with fibrous degen- 

 eration; in the pleural space between the lungs and slightly attached to 

 the diaphragm was a large cyst lull of purulent liquid and having the 

 capacity of about one quart. 



The remainder of the suspected animals were placed by themselves at 

 a considerable distance from the others of the herd, and Mr. Dye con- 

 sented to consider the whole place in quarantine until such time as I 

 could declare all danger to be past. 



Mr. Dye does not know how the disease was introduced into his herd. 

 He had purchased a number of grade Jersey cattle in the vicinity of 

 Baltimore and a large number of registered Jerseys from the herd of 

 the late John W. Garrett, the of the same county, in November, 1883. 

 The same month he purchased fifteen head of A. M. Herkness, of Phila- 

 delphia, a part at private sale, and a part at his auction. Two weeks 

 earlier than this he had purchased a car-load of registered Jerseys at 

 Kellogg's combination sale in New York. All of these cattle were 

 shipped to his farm at Troy. I believe that the disease was brought 

 with the grade Jerseys which had been gathered up in the vicinity of 

 the city of Baltimore. I have been unable to find pleuro-pneumonia in 

 any herds, so far as examined, from which the other cattle came, and 

 it seems very evident that if the disease had existed in Mr. Garrett's 

 herd or among any cattle at Herkness' auction, or at Kellogg's sale, it 

 would have been carried to other places, and we should have found it 

 in many other herds besides that of Mr. Dye and those which had
