A large land-holder in England has planted an immense fruit farm, 40,000 plum trees being one of the items set out. In order to make a perfect thief-proof fence, he has surrounded the farm with cotton-wood poplars set only a foot and a half apart. By the time the fruit trees are in bearing the trunks of the trees will touch each other. Then he proposes to head them off 18 feet from the ground, and keep the sprouts cut back to this point every two or three years thereafter. In this way he expects to have a living wall 18 feet high, that will at least last as long as the fruit trees in the orchard last.
