Its structure is sufficiently generalized to make observation of the external structure easy, and the various species are widely distributed and usually abundant in the autumn at a time when many schools begin the study of zoology. For the living animal the local species may be used, and the work may be carried on in the field or in the laboratory. Specimens may be collected till quite late in the autumn, in grassy areas in the central and eastern United States, and they will live for some time if kept in a breeding-cage or other receptacle, with a piece of sod.

The i development of the locust should be studied by means of specimens collected by the pupils or teacher, or obtained of dealers in natural-history supplies.
