Excerpt

The conditions governing the preparation of the first edition of this book, in which a large number of authors participated, did not permit any one author to read the contributions of the others. There were therefore only a limited number of cross references and some duplication. In this second edition we have tried to correct both these defects. All statistics have been brought up to date so far as data were available, some chapters have been reworked to fit, changing conditions, and we have added a new chapter on the conservaition of commercial fish, entitled "Fisheries of the Future." The general plan of the first editon has been followed.

The interval between the publication of the first and second editions is all too brief to show any great advance in conservation; yet some progress has been made. First of all, a larger percentage of our people are becoming conservation-minded. Federal erop control, which people soil conservation, has aroused the interest of, a great number of the farmers. Hunting and fishing clubs have cooperated with the wildlife conservationists as never before. Thus has the urban been drawn into the conservation movement. The greatest advance in any phase of conservation one notices in recreation, involving of course hunting and fishing. Estimates of the money spent for recreation range from two to five billions, of dollars a year for the nation. City, state, and national governments have greatly expanded the recreational facilities. Science has continued to expand its work in the utilization of waste products, the recovery of metals, a better utilization of coal, petroleum, and their products, and, lastly, in the saving of human life.
