Pyramids.—For pyramids (a form of training applied most frequently to dwarf pears), the early treatment is quite differ- ent from that of standards. As the sap tends to the summit of the tree, producing the strongest side-shoots toward the top, and the shortest and most feeble toward the bottom, the natural form of the tree gradually becomes a trunk or stem with a branching head. To prevent this result, and give a strong, broad set of branches at the bottom, a thorough and regular system of shortening-down must be adopted at the outset. The following is a brief outline of the course usually pursued: After the single shoot from the bud has grown one season (Fig. 140), it is cut down so as to leave not over one foot, and if the tree is weak not over six inches (Fig. 141). As a conse- quence, the buds on this remaining portion, receiving all the sap, make a vigorous growth. The upper one must be converted into a leader, by pinching off early the ^40.

Six inches of naked stem below the branches should be left, by rubbing off all shoots below; and if in a region liable to deep snows, this space should be a foot, to prevent splitting off the limbs by the weight of the snow, and for which object the tree should not be cut down lower than eighteen inches at the close of the first season. The pruning after the second year's growth, consists in cutting down again the leader for a second crop of side-shoots; and these side-shoots, and the new leader,
