4? 2 EEPOET OF THE COMMISSIONER OF AGEICULTUEE. 



most of tJtie outbreaks in Delaware to infected animals brought frdni 

 Baltimore. It is to be noted, however, that cows arc frequently takeu 

 to this i^art of Delaware from Chester and Lancaster Counties, Penn- 

 sylvania, where there have recently been affected herds. Dr. Eosc saw 

 40 cows which had been driven from these counties to Wilmington on 

 the day of his visit, which were sold there. It should also be oljserved 

 that the supervision in none of these cases has been so rigorous as to 

 prevent new stock from being added to the herds, or the conceiilnicnt 

 of cases of the disease which may have occurred during the ])erio(l of 

 quarantiue. In some instances animals were brought and placed in 

 the quarantined herds without the knowledge of the State veterinarian, 

 and it is very evident that cows which contracted the disease might 

 easily have been destroyed and replaced with fresh animals in order to 

 convince the inspector that no cases of disease had occurred, and in 

 that way prevent the extension of the period of isolation. This f;ict ts 

 also to be taken into consideration in estimating the beneficial ellects 

 of the inoculation of these herds. 



NEW JEESEY. 



The inspections in this State have been kept up during the greater 

 I)art of the year, and a large number of herds have been inspected. Isy 

 co-oi)eration with the State board of health, which has charge of the dis- 

 eases of animals in this State, infected herds have been quarantined 

 and much has been done to reduce the prevalence of the disease. 



PENNSYLVANIA. 



In order to learn to what extent pleuro-pueumonia is disseminated in 

 this State, two inspectors were sent there at different times during the 

 year with instructions to investigate and learn if the disease existed in 

 any herds that were not in charge of the State authorities. Neither 

 of these inspectors were able to find any cases except those which 

 had already come to the knowledge of the State veterinarian. Dr. 

 Rose, who made the last inspection in October, 1885, rei)orted that 

 the contagion still existed on the farms near "West Cliester, Chester 

 County, which I visited in 1884. Some of these herds had been inocu- 

 lated by the State veterinarian, but the disease continued to develop 

 long after the operation was performed. The herd of Levi Lewis, which 

 had been inoculated, was one of those in which the infection has con- 

 tinued to exist. Three cows purchased since June have all contracted 

 I)leuro-pneumonia; two were sick at the time of the visit, and one had 

 made a partial recovery. Mr. Lewis stated that every new animal taken 

 into the herd developed more or less symptoms of the disease after it 

 had been with the other animals a certain length of time. It has been 

 reported that animals have been sold from herds in this condition. Such 

 herds have not been and cannot be held safely in quarantine during the 

 period that is required to destroy the contagion by the methods there 

 adopted. 



MAEYLAND. 



A thorough inspection of this State has not been made. One of the 

 inspectors of this Bureau is now engaged in this work in the vicinity of 

 Baltimore, but has only lately comnwenced, and consequently there are 

 few returns up to this time. The following table gives a condensed state-
