TAILIEUCHUNG - AN ELEMENTARY STUDY OF INSECTS

In the preparation of a book of this nature, to be used in the grade schools, we realize that the one fundamental thing to keep in mind is the economic importance of the insect, be it good or bad. The child wants to know what is good and what is bad and how he can make use of the good and how he can get rid of the bad. And yet there is something more associated with the life, work and development of each tiny insect. There is a story—a story of growth, not unlike that of the developing. | AN ELEMENTARY STUDY OF INSECTS By LEONARD HASEMAN Professor of Entomology in the University of Missouri Columbia Missouri MISSOURI BOOK COMPANY 1923 CONTENTS.
