Unselfish Devotion To This Cause
IN our work with boys and girls in the public schools and with college students in agriculture we have found that the greatest interest was taken in subjects that answered the following question, “What I am going to do with it?” They are not satisfied with the life history and habits of insects unless the methods are explained by which they may be controlled, provided the methods given are practical.
The stories in this book are written for the boys and girls and for those persons who know nothing about insects and how to fight them. The authors have tried to write them in simple language and no attempt has been made at exhaustive discussions. The control measures have been confined to such as may be readily employed by any one troubled by the insects treated. Though the articles have been written in story form to assist and teacher and parent to interest the child, the facts viii in regards to insects are correct, while nearly every incident mentioned has at some time or other come within the experience of the authors.
The articles are action stories and the figures as far as practicable represent action. It has been the aim to make each story sufficiently complete to give the reader a clear view and a working knowledge of the subject. The same plan of presentation is not adhered to in order to avoid monotony. Plans for investigating insects have been embodied in a few of the articles to enable the child to understand how the facts were obtained.
The boys and girls constitute the greatest asset in our national life. There is no greater force on earth available by which we can induce parents to adopt better practices than the boys and girls. In shaping our agriculture for the future the progress made will be in direct proportion to the extent to which we can interest them.
In the preparation of these stories we are indebted to the work and writings of entomologists past and present. Especially helpful has been the work of the Sections of Southern Field Crop Insects, and Cereal and Forage Crop Insects, Bureau of Entomology, U. S. Department of Agriculture; Dr. W. E. Hinds, Entomologist, Alabama Experiment Station, and Dr. S. A. Forbes, State Entomologist of Illinois. A number of the illustrations ix were obtained from various sources, due credit being given in each case.
In the preparation of the manuscript and a number of negatives the authors are indebted to Mrs. A. F. Conradi for valuable assistance.
