Présentation de l'éditeur
The Plan. The general plan of the book is to introduce each of the larger groups of animals by the careful study of a typical representative. It is the aim to present a fairly complete picture of the life of this type, its place of living; its manner of securing food; its enemies and its means of protection; its mode of locomotion; the processes of digestion, circulation, and respiration; its sense organs; its development; its relations to the plant world, to other animals, and to man. Following the study of the type is a general account of representative forms. The characteristics of the group are given in summarized form. Each chapter closes with a tabular classification of the group. Time for theS tudy of Zoology. Of the three seasons during which school is in session, winter is the least desirable for the study of animals. Many of the birds have migrated; most of the insects have been killed; those that remain alive are in close hiding and are hard to find, and still more so are their eggs, larvae, or pupae. A large number of animals are hibernating. Animal life is at low ebb. The choice of time, then, is practically limited to fall and spring. While there is an abundance of life in the spring and some forms can better be studied then, on the whole animal life is at its highest activity in the fall. A gain, since spring is preferred for botany, the fall seems the best time for zoology. The Order of Study. The chief aim is to understand the lives of animals. To know them it is necessary to study them in relation to their surroundings. To do this to the best advantage they should be studied when at the hight of their activity. These points, then, must largely determine the order of study. For instance, if zoology is begun in the fall, one finds insects active and abundant.
