The shoots are allowed to take their natural course, being tied to any wire near which they chance to grow, finally lopping over the top wire. Sometimes the canes are bent down and tied horizontally to the wires, and this is probably the better practice. Two canes may be tied in each direction on the lower wire, or the two inner canes may be tied down to the second wire. In either case, the vine is essentially like the High Renewal, except that the trunk is shorter. [Illustration: 19. FAN TRAINING, AFTER PRUNING.] CHAPTER IV. THE DROOPING SYSTEMS. In 1845 William T. Cornell planted a vineyard in the Hudson River Valley. A neighbor, William Kniffin, was a stone mason with a few acres of land to which he devoted his attention during the leisure seasons of his trade. Cornell induced Kniffin to plant a few grapes. He planted the Isabella, and succeeding beyond his expectations, the plantation was increased into a respectable vineyard and Kniffin came to be regarded as a local authority upon grape culture. Those were the pioneer days in commercial grape growing in North America, and there were no undisputed maxims of cultivation and training. If any system of close training and pruning was employed, it was probably the old horizontal arm spur system, or something like it. One day a large limb broke from an apple-tree and fell upon a grape-vine, tearing off some of the canes and crushing the vine into a singular shape. The vine was thought to be ruined, but it was left until the fruit could be gathered. But as the fruit matured, its large size and handsome appearance attracted attention. It was the best fruit in the vineyard! Mr. Kniffin was an observant man, and he inquired into the cause of the excellent fruit. He noticed that the vine had been pruned and that the best canes stood out horizontally. From this suggestion he developed the four-cane system of training which now bears his name. A year or two later, in 1854, the system had attracted the attention of those of his neighbors who cultivated grapes, and thereafter it spread throughout the Hudson valley, where it is to-day, with various modifications, the chief method of grape training. Its merits have become known beyond its original valley, and it is now spreading more rapidly than any other system. The ground upon which the old Isabellas grew is now occupied by Concords, which are as vigorous and productive as those grown upon newer soils. William Kniffin died at his home in Clintondale, Ulster county, New York, June 13, 1876, at fifty-seven years of age. The portrait is from a photograph which was taken two or three years before his death. [Illustration: 20. WILLIAM KNIFFIN.]
