The book is a practical and scientific text most useful in the teaching of biology. It lays special emphasis on some of the all important economic phases of the animal and plant worlds. The book also attempts to guide in the matter of controlling some of the more common pests and diseases. The book has emerged out of the author's practical experience in teaching biology and hence, keeping in mind the shortcomings normally observed in this sphere, attempt has been made in the text, to arouse in the reader, an interest in some of the sciences that have a close bearing on agriculture and which are, therefore, closely relating to some of the most important problems concerning human welfare. The sciences of zoology, entomology, botany, plant pathology, bacteriology and pomology, each of which is important in its relation to the broader and all-inclusive subject of Biology, deal with fundamental facts that are of interest to every student. Some of these facts might not have been given their proper evaluation as a part of one's education which gap is attempted to be bridged by this work. A few good suggestions that may be of interest to the teacher have been made at the end of the various chapters. While the emphasis is that much more can be accomplished in outdoor observations, experiments etc than in the classroom laboratory experiments the book will lend itself well with any good laboratory manual. The book is a worthwhile addition to the treasure of teachers as well as students alike. (jacket).
