Allegan County, north of Van Buren, along the lake shore at least, suffered from yellows rather less, though nearly as badly as the region to the south. The disease was less and less virulent as the peach-belt extends northward. At Traverse City, the most northern point in the peach-belt, yellows has never been epidemic. Passing eastward, the disease appeared about Grand Rapids, the center of peach-culture in Kent County, in 1883 and in the decade that followed took from peach-growers the toll usual in western Michigan. Eastward from Kent County, however, in the several small and rather isolated cases of peach-growing yellows either has not appeared or has been an unimportant factor. The lowest ebb in Michigan orchards from yellows was reached in the eighties after which new plantings increased remarkably, the number of bearing trees in 1889 being but 1,919,104 and in 1899, 8,104,415. The disease still persists in Michigan wherever in former times it became established. Yellows seems, however, to have lost much of its old time virulency; or, perhaps, the fact that peach-growers are more prompt and thorough in destroying diseased trees accounts for the decrease of the disease. Then, too, the Michigan peach-belt has had the bitter experience in the last decade or two, of several winter freezes which have wiped out whole orchards, discouraged many planters, and, together with the keen competition of new peach-regions, reduced the size of orchards and scattered the plantations so that, in the lessened communal intensity, yellows has less opportunity. Going back, now, to the place of first infection and passing southward, we find that yellows, though not more virulent in Delaware than in Michigan, was much more devastating. Destruction is the only efficient method in treating yellows. The necessity of this drastic measure has been proclaimed by every authority from Judge Peters, discover of yellows, down. The strong arm of the law in many states enforces destruction. In Delaware, however, growers were more dilatory in destroying yellows-trees than elsewhere--in fact for the first half-century made little attempt so to check the disease. When the scales fell from the eyes of orchard-owners in this State the industry was already ruined. From hundreds of accounts, the ups and downs of peach-growing in Delaware as caused by yellows may be shown by a few brief statements.
