Thursday, December 19th, was selected for the purpose of making an examination of the Hancock herds; but, after some ten or twelve animals had been examined and all pronounced tainted with the disease, the owners concluded to stop the investigation, expressing themselves dissatisfied with the result, as not one of the animals examined had shown any symptoms of disease. In order to convince them of the correctness of the diagnosis, a cow was selected and destroyed, which the Hancocks believed to be in perfect health. Upon opening the animal, several small patches of hepatized lung were brought into view. Upon making a longitudinal section of the lump, as both were involved, they presented a red, speckled appearance. All the other tissues were healthy. The symptoms in these cases were quite different from any which had been previously seen in an experience of three years with the disease in and about Philadelphia, inasmuch as they were not preceded by cough; in fact, cough did not appear in many of the animals at any time during the progress of the disease. The animals looked, ate, and milked well, previously to the development of the disease, so that the owners were thrown completely off their guard by these deceptive symptoms of health. Knowing the uncertain character of this disease, and wishing to stay its ravages, a suggestion was made by the author as to the propriety of having the entire herd killed for beef. This was done the more readily, as the sale of the meat is legalized in Europe, it being regarded as uninjured, and therefore wholesome meat. This suggestion was acted upon, and thus these two farms were rid of this dreadful scourge at one blow. Mr. A. Gaskill, of Mount Holly, N. J., purchased a cow from one of the Hancocks, for his own family use, which was sent to Mr. Frank Lippincott's to pasture and turned in with Mr. L.'s own herd. Soon after, this cow sickened and died. This was soon followed by the loss of six of Mr. L.'s own cattle,--three oxen, two cows, and one steer. From this herd, it was communicated to the Widow Lippincott's, who occupied a neighboring farm; as also to Mr. Cleavenger's, who lost four animals; and to Mr. Smith's, who had, at one time, seven animals sick; and from Cleavenger's to Noaknuts, who lost two cows. Some two or three cows, belonging to Mr. Logan, in the same neighborhood, got upon the road and broke into Mr. Lippincott's pasture, mixing with his herd. As soon as Mr. Logan was informed of the fact, he isolated these cows by enclosing them in a pen at some distance from his other cattle; but they managed to break out, and mingled with his other stock. It could scarcely be expected that his herd could escape the disease, considering the exposure to which they had been subjected. The disease manifested itself in the herds of several other farmers in the country, but space will not allow a more extended notice of the subject.
