Excerpt from Our Insect Friends and Enemies: The Relation of Insects to Man, to Other Animals, to One Another, and to Plants, With a Chapter on the War Against Insects Nothing in this world of ours exists to, for or by itself alone. Every living creature depends upon some other form of life, or upon inorganic matter and is, in turn, the dependence of others that find it useful or essential for continued existence. And as inorganic matter is, after all, the base of organic matter as we know it, plus the addition that makes it organic and whose nature we do not yet know, so in due course all organised forms again return to their lifeless constituents. Every living thing, then, has relations to many other living things and some of these relations, so far as insects are concerned, it is my object to present. I need hardly disclaim any attempt at completeness; but so far as the presentation goes it claims accuracy. A large proportion of the facts have been personally observed or verified, others arc common knowledge and all are based upon the observations or records of scientific investigators. Some of these relations of insects to the welfare of man have been but recently worked out and are imperfectly known; yet enough has come to the general information to arouse a decided interest in these long despised creatures. Their presence or absence from our midst may make all the difference between sickness and health, irritation and comfort, poverty or wealth, or, on the other hand, wealth and poverty. They make some regions uninhabitable that would otherwise be attractive as sites for homes and, altogether, their influence upon humanity, directly and indirectly, is vastly greater than is generally realized.
