This is an ex-cellent work by a well known authority and will be of great value to those persons who wish to have a guide to all the varied interests at-tached to insect life. A good idea of the scope of the work may be obtained from the contents as follows : Insects in their relation to the animal kingdom; Insects in their relation to plants as benefactors ; In their relation to each other ; In their relation to the animals that feed on them; In their relation to weather and diseases that affect them ; In their relation to other ani-mals ; In their relation to man as benefactors; In their relation to man as carriers of disease; Insects in their relation to the household; In their relation to the farmer and fruit-grower; The war on insects.
