Feeding Farm Animals

By Professor Thomas Shaw. This book is intended alike for the student and the farmer. The author has succeeded in giving in regular and orderly sequence, and in language so simple that a child can understand it, the principles that govern the science and practice of feeding farm animals. Professor Shaw is certainly to be congratulated on the successful manner in which he has accomplished a most difficult task. His book is unquestionably the most practical work which has appeared on the subject of feeding farm animals. Illustrated. 5½ × 8 inches. Upward of 500 pages. Cloth. $2.00

Profitable Dairying

By C. L. Peck. A practical guide to successful dairy management. The treatment of the entire subject is thoroughly practical, being principally a description of the methods practiced by the author. A specially valuable part of this book consists of a minute description of the far-famed model dairy farm of Rev. J.D. Detrich, near Philadelphia, Pa. On the farm of fifteen acres, which twenty years ago could not maintain one horse and two cows, there are now kept twenty-seven dairy cattle, in addition to two horses. All the roughage, litter, bedding, etc., necessary for these animals are grown on these fifteen acres, more than most farmers could accomplish on one hundred acres. Illustrated. 5 × 7 inches. 200 pages. Cloth. $0.75

Practical Dairy Bacteriology

By Dr. H. W. Conn, of Wesleyan University. A complete exposition of important facts concerning the relation of bacteria to various problems related to milk. A book for the classroom, laboratory, factory and farm. Equally useful to the teacher, student, factory man and practical dairyman. Fully illustrated with 83 original pictures. 340 pages. Cloth. 5½ × 8 inches. $1.25

Modern Methods of Testing Milk and Milk Products

By L. L. VanSlyke. This is a clear and concise discussion of the approved methods of testing milk and milk products. All the questions involved in the various methods of testing milk and cream are handled with rare skill and yet in so plain a manner that they can be fully understood by all. The book should be in the hands of every dairyman, teacher or student. Illustrated. 214 pages. 5 × 7 inches. $0.75

Animal Breeding

By Thomas Shaw. This book is the most complete and comprehensive work ever published on the subject of which it treats. It is the first book which has systematized the subject of animal breeding. The leading laws which govern this most intricate question the author has boldly defined and authoritatively arranged. The chapters which he has written on the more involved features of the subject, as sex and the relative influence of parents, should go far toward setting at rest the wildly speculative views cherished with reference to these questions. The striking originality in the treatment of the subject is no less conspicuous than the superb order and regular sequence of thought from the beginning to the end of the book. The book is intended to meet the needs of all persons interested in the breeding and rearing of live stock. Illustrated. 405 pages. 5 × 7 inches. Cloth. $1.50

Forage Crops Other Than Grasses

By Thomas Shaw. How to cultivate, harvest and use them. Indian corn, sorghum, clover, leguminous plants, crops of the brassica genus, the cereals, millet, field roots, etc. Intensely practical and reliable. Illustrated. 287 pages. 5 × 7 inches. Cloth. $1.00

Soiling Crops and the Silo

By Thomas Shaw. The growing and feeding of all kinds of soiling crops, conditions to which they are adapted, their plan in the rotation, etc. Not a line is repeated from the Forage Crops book. Best methods of building the silo, filling it and feeding ensilage. Illustrated. 364 pages. 5 × 7 inches. Cloth. $1.50

The Study of Breeds

By Thomas Shaw. Origin, history, distribution, characteristics, adaptability, uses, and standards of excellence of all pedigreed breeds of cattle, sheep and swine in America. The accepted text book in colleges, and the authority for farmers and breeders. Illustrated. 371 pages. 5 × 7 inches. Cloth. $1.50

Clovers and How to Grow Them

By Thomas Shaw. This is the first book published which treats on the growth, cultivation and treatment of clovers as applicable to all parts of the United States and Canada, and which takes up the entire subject in a systematic way and consecutive sequence. The importance of clover in the economy of the farm is so great that an exhaustive work on this subject will no doubt be welcomed by students in agriculture, as well as by all who are interested in the tilling of the soil. Illustrated. 5 × 7 inches. 337 pages. Cloth. Net. $1.00

Land Draining

A handbook for farmers on the principles and practice of draining, by Manly Miles, giving the results of his extended experience in laying tile drains. The directions for the laying out and the construction of tile drains will enable the farmer to avoid the errors of imperfect construction, and the disappointment that must necessarily follow. This manual for practical farmers will also be found convenient for reference in regard to many questions that may arise in crop growing, aside from the special subjects of drainage of which it treats. Illustrated. 200 pages. 5 × 7 inches. Cloth. $1.00

Barn Plans and Outbuildings

Two hundred and fifty-seven illustrations. A most valuable work, full of ideas, hints, suggestions, plans, etc., for the construction of barns and outbuildings, by practical writers. Chapters are devoted to the economic erection and use of barns, grain barns, horse barns, cattle barns, sheep barns, cornhouses, smokehouses, icehouses, pig pens, granaries, etc. There are likewise chapters on birdhouses, doghouses, tool sheds, ventilators, roofs and roofing, doors and fastenings, workshops, poultry houses, manure sheds, barnyards, root pits, etc. 235 pages. 5 × 7 inches. Cloth. $1.00

Irrigation Farming

By Lute Wilcox. A handbook for the practical application of water in the production of crops. A complete treatise on water supply, canal construction, reservoirs and ponds, pipes for irrigation purposes, flumes and their structure, methods of applying water, irrigation of field crops, the garden, the orchard and vineyard, windmills and pumps, appliances and contrivances. New edition, revised, enlarged and rewritten. Profusely illustrated. Over 500 pages. 5 × 7 inches. Cloth. $2.00

Forest Planting

By H. Nicholas Jarchow, LL. D. A treatise on the care of woodlands and the restoration of the denuded timberlands on plains and mountains. The author has fully described those European methods which have proved to be most useful in maintaining the superb forests of the old world. This experience has been adapted to the different climates and trees of America, full instructions being given for forest planting of our various kinds of soil and subsoil, whether on mountain or valley. Illustrated. 250 pages. 5 × 7 inches. Cloth. $1.50
