Still passing northward from the first center of infection, we come to New York, where, according to Wm. Prince, in a foregoing quotation, the disease appeared as early as 1801. The son of this writer, W. R. Prince, in the continuation of the article quoted on page 121, written in 1846, says: "In this island the malady became exhausted some years since by the utter destruction of the old orchards, and the determination not to plant new ones until it became extinct. This proved most fortunate as the disease has been for years banished from Long Island, and now new orchards are springing up everywhere, and every garden is becoming readorned with the finest varieties of the Peach 'redolent with health.'" A. J. Downing,[224] writing in 1849, reports: "Fifteen years ago there was scarcely a tree in the vicinity of Newburgh that was not more or less diseased with the yellows. By pursuing the course we have indicated (destruction by burning), the disease has almost disappeared." Thirty years later, Charles Downing, writing from Newburgh, states: "We have had the yellows here at intervals for over sixty years, some times continuing for five or six years and then several years free from it." At present, 1916, peaches are freely planted along the Hudson in the region of which the Downings wrote, and, whether from following the method of A. J. Downing in burning the trees, or whether we are in one of the intervals of immunity noted by Charles Downing, peach-yellows, while present, causes but small losses. One might enlarge at length on the vagaries of yellows but we can concern ourselves only with the main facts of its history. We now follow the disease from eastern to western New York.
