Principles and Practice of Pruning 



By H. G. KAINS 



Lecturer on Horticulture, Columbia University 



Pew practices in the handling of plants, especially 

 fruit bearing plants, attract so much Interest as do those 

 of pruning. The methods are so varied, the results so 

 diverse, and the opinions of growers so apparently con- 

 tradictory that this subject Is always one of the most 

 interesting, and the surest to hold attention and arouse 

 discussion. 



Particularly during the last ten or fifteen years when 

 the principles of plant physiology have been more and 

 more satisfactorily applied to plant production and man- 

 agement has Interest settled In pruning. During the 

 latter half of this time also more and more investi- 

 gations and tests have been conducted by experiment 

 stations and other workers to test out methods and 

 principles in the Interest of science and for the benefit 

 of growers. The accumulation of such new knowledge 

 has become very considerable especially In the last de- 

 cade, but it is necessarily so scattered that very few 

 growers have access to It, hence the demand for a book, 

 which shall present the really Important features of 

 these Investigations as well as set forth the fundamental 

 principles based upon the lows of plant growth. 



This volume Is lavishly Illustrated mainly by actual 

 photographs of specimens which show good and bad 

 practices. The author has spared neither time nor ex- 

 pense In gathering his photographs, each one of which 

 tells Its story. 



After a few pages of introduction the author discusses 

 Plant Physiology as related to pruning. A chapter 

 takcB up the Philosophy of Pruning, Itself a very in- 

 teresting subject. Then follows a classification and clear 

 discussion of Buds, very fully Illustrated from life. How 

 WoundB Heal is an exceedingly interesting chapter, as are 

 also those on Prevention and Repair of Mechanical In- 

 juries, Pruning Nursery Stock, Young Trees. Mature 

 TreeB and Odd Methods of Pruning and Training, Re- 

 juvenating Neglected Trees and Practical Tree Surgery.

Plant Propagation, Greenhouse 

 and Nursery Practice 



By M. G. KAINS 



We have had many inquiries from time to time 

 for a reliable and up-to-date book on plant propa- 

 gation, but were always at a loss to find any pub- 

 lication that we could recommend. The subject 

 has been dealt with in fragmentary manner only 

 in books that have come to our notice. So it is 

 well that this new work has been issued, espec- 

 ially as it is both comprehensive and practical, 

 and it should meet with a ready sale among 

 plantsmen. nurserymen and gardeners. There are 

 nineteen chapters covering in detail topics of ger- 

 mination and longevity of seeds, propagating by 

 buds, layering, cuttings, grafting, etc., fruit tree 

 stocks, scions, etc., and there are eight pages of 

 condensed cultural instructions in tabulated form, 

 covering annuals and pe/ennials from seed, 

 woody plants, evergreens, vines, bulbs and tubers, 

 greenhouse and house plants, ferns, palms, water 

 plants, orchids and cacti. The illustrations are 

 numerous, comprising 213 figures and halftone 

 plates. There are 322 pages well bound and on 

 heavy paper, teeming with helpful information. 

 It is a book which no cultivator can afford to do 

 without. It is worth many times its price. Copies 

 can be supplied from the office of HORTICUL- 

 TURE at publisher's price, $1.50.
