A correspondent inquires when the yellows made its first appearance in this country and where? We cannot answer him. No doubt it was in existence long before public attention was called to it, and before it was recognized as a distinct disease. At the end of the last century we find in the literature of the time many complaints about the short-lived nature of the tree of "late years," and in 1805, the American Philosophical Society offered a premium of sixty dollars for the best essay which should point out the cause and the remedy for this disease. For the essays which received the money we would not give sixty cents in our time, but it goes to show the great concern which some trouble, tending to make the peach short-lived, gave even at that time, and it is more than likely it was what we now know as "yellows." People did not look into microscopic matters as closely then as they do now-a-days.
