The encyclopedia of practical horticulture; a reference system of commercial horticulture, covering the practical and scientific phases of horticulture, with special reference to fruits and vegetables;. Gardening; Fruit-culture; Vegetable gardening. APPLES 131 the 24-inch scions than with the 6-inch ones Theie was no constant difference in growth between the trees grafted above the crown and those grafted be- low it. In 1894 the above experiment was re- peated in part with Winesap, Ben Davis, and Missouri Pippin apples, using 6, 12, and 24-inch scions on whole roots and 5-inch piece-root stocks grafted above and below the crown. After two years' growth there was no constant difference between the trees grafted above the crown and those grafted below, either as regards height or diameter. The length of the stocks and scions had a marked influence on the growth, the dif- ference in favor of the long stocks and long scions being practically constant in all cases. The height of 2-year-old trees grafted on whole roots average 21 per cent greater than on 5-incli stocks and the diameter over 3 per cent greater. Trees from 24-inch scions averaged 10 per cent higher than from 12-ineh scions, and 20 per cent higher than those from 6-inch scions. Their diameters were 27 per cent greater than the trees from 12-inch scions and 34 per cent greater than those from 6-inch scions. These differences were not nearly so marked after the trees had made three years' growth, the diameter of the trees from 24-inch scions at that time averaging only 6 per cent greater than those from the 12-inch scions and only 7 per cent greater than those from the 6-inch scions as against 27 per cent and 34 per cent, respectively, after two years' growth. In 1895 grafts were made with 12 and 6-inch scions on whole roots, 5-inch roots, and 21/^-inch roots, grafted above and be- low the crown. In addition a stock grafted above the crown, with roots cut eight inches long, was tested. After two years' growt
