THE QUALITY PLACE OF BOSTON 



Regarding the Kroeschell, It Is the 

 best we have ever had and satisfac- 

 tory beyond our expectations. It heats 

 up especially quick and has saved us 

 considerably already in the price of 

 fuel. When we are in need of another 

 boiler we will give the Kroeschell the 

 first consideration.

OHIO'S CELEBRATED CYCLAMEN 

 SPECIALIST 



After using your No. 12 Kroeschell 

 Boiler I came to the conclusion that 

 had I to install more boilers it would 

 be the Kroeschell and no other. It 

 really is a pleasure to heat, no trouble 

 to get the desired heat in a very short 

 time.

Principles and Practice of Pruning 



By M. G. KAINS 

 Lecturer on Horticulture, Columbia Dniversitj 



Few practices in the handling llf plants, especially 

 fruit bearing plants, attract so much interest as do those 

 of pruning The methods arc 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 ami 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 "rowers. The accumulation of such new knowledge 

 lias become very considerable especially in the last de- 

 ,.;,,!,. i,ut 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 laws of plant growth. 



This volume is lavishly illustrated mainly by actual 

 photographs of specimens which show good and bad 

 practices The author lms spared neither time nor ex- 

 pense in gathering his photographs, each one of which 



tells its story. 



\ftor i few pages of introduction the author discusses 

 Plant Physiology as related to pruning A chapter 

 takes 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 

 Wounds Heal is an exceedingly interesting chapter, as 

 are also those on Prevention and Repair of Mechanical 

 Inluries, Pruning Nursery Stock. Young Trees, Mature 

 Trees and Odd Methods of Pruning and 1 raining. Re- 

 juvenating Neglected Trees and Practical free Surgerj

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 piihllsher'B prire. $1 50
