PESTS OF THE GARDEN AND ORCHARD, FARM AND FOREST. By

Ray Palmer and W. Percival Westell. (Drane. 25s. net.) The authors justly describe this as a practical guide. It is carefully written and very well illustrated. The first and longest section is devoted to insects, the next to birds and other animals. Then come chapters on fungoid diseases and obnoxious weeds, followed by an account of insecticides and fungicides, spraying tables, a glossary and indices. The authors describe each pest and then suggest the antidote. We are glad to find that they distinguish clearly between the few birds, like the sparrow, that probably do more harm than good, and the many birds which are the farmer's friends. But in view of the enormous damage done by insects even the sparrow deserves to be accorded the benefit of the doubt.
