. The care of trees in lawn, street and park. With a list of trees and shrubs for decorative use. Trees; Trees. CHAPTER II CHARACTERISTICS, STRUCTURE, AND LIFE OF TREES HE woody plants, trees, shrubs, and some vines, differ from all other plants in at least two directions: namely, in their persistent life, with only temporary rest periods in growth, — a characteristic which indicates differences in structure from that of annuals — and in their elevation in height above the rest of vegetation, which implies, besides difference in structure, difference in performing the functions of life. Trees as a rule show these two characteristics of height and persistency of life in a most pronounced degree. In addi- tion, they differ from shrubs and vines by their form; namely, a single stem, rising from the ground, — the bole or trunk, — which develops more strongly than the branches, into which it divides in characteristic fashion, and which in their aggregate may be dift'erendated as the crown. These char- acteristics of form, longevity, and height make trees the most prominent and one of the most important, and most interesting features in the living vegetable world. To be able to care for trees, to diagnose diseases or abnor- mal conditions and to apply remedies judiciously, it is neces- sary to know and understand something of the structure, and of the life requirements of a healthy tree in normal condition. Indeed, we may say that only to the extent that this primary knowledge is possessed, can a rational treatment of trees be expected. 5.
