"The ergot, or spur of the hay, is confined to the June grass, as far as my observation extends; owing, probably, to its early maturity. Most other kinds of grass are cut before the seeds have matured sufficiently to produce the spur. I was suspicious of the foulness of the feed before I examined any hay, and have found the spur in the hay wherever the disease is found. "Mr. Sanford, of Edinburgh, Ohio, purchased one half of a mow of hay from Mr. Bassett, of Randolph, which was removed to his farm in Randolph, eight miles distant. Of this hay, Mr. Sanford fed eleven cows some six or eight weeks. Mr. Bassett had been feeding the same to four cows. At about the same time, both heads began to show lameness. I visited Mr. S. after he had lost six cows, and examined the remaining five, four of which were lame and the other showed symptoms of the disease. He had two other cows, one of which was loaned to a neighbor, and the other was fed upon different hay, for convenience. The loaned cow was returned about the first of March,--the two then running with the ailing ones until the 24th of April, when I saw them sound and in good health. "I then visited Mr. Bassett's stock, which I found infected with the same disease,--he having lost one, and the remaining three being lame, and much debilitated. The hoofs were sloughing off. Some of the same hay remained in the snow, which, upon examination, exhibited an abundance of the spur. Upon inquiry, I found that no such disease existed between the two farms, or in the neighborhood of either Mr. S. or Mr. B. The peculiarity of this circumstance at once swept away the last vestige of doubt from my mind. Mr. E. Chapman, of Rootstown, accompanied me, and can vouch for the correctness of these statements. "He hooted at my opinions, asserting that he understood the disease, and that it was caused by the freezing of the feet. He has since, however, abandoned that idea, and honestly 'acknowledged the corn.' This ergot is regarded by some as a parasitic fungus, formed in other grains, an abundant vegeto-animal substance, and much disposed to putrefaction. We appear to be in the dark regarding its real composition. The little which has been written upon the subject, appears to be founded upon hypothesis, and that the most obscure. The articles to which I refer may differ in quality or property to a considerable extent, and we may forever remain in the dark, unless chemical investigation be instituted.
