B. M. D., Spring Garden, Pa., writes: " Wanting to make a vinery for foreign grapes under glass, I went to considerable trouble to dig out a border three feet deep in the clay, and fill in with good earth, with bones and other rich matters to feed the vines, in accordance with the directions in the best works I could obtain on the subject. An English gardener whom I have taken to look after my place says this is all wrong, and that it is more hurt than profit. He says that in England they do not let the grape roots go deep, but very often put a mortar floor under the ground about eighteen inches from the top, so as to prevent them. The gardener seems to understand his business, but how about this advice of the books?"
