 PLANT 



We spent $100,000 in building and equipping 

 the largest modern mushroom plant in the 

 world. We purchased in every instance the 

 best of everything we could get. and the fact 

 that we Installed a Kroeschell Holler to fur- 

 nish our heat is sufficient evidence of our 

 opinion of same 



Since installing this boiler and operating it 

 we have never had any reason to change our 

 opinion.

Principles and Practice of Pruning 



By M. O. KAIMS 



Lecturer on Horticulture. Columbia TJnlTeralty 



Pew practices In tbe handling »f plant!, especially 

 fruit bearing plants, attract ao much lntereat aa do those 

 of pruning. The metboda are ao varied, tbe results ao 

 diveree, and the opinions of growers ao apparently con- 

 tradictory that thla subject la alwaya one of the moat 

 interesting, and the surest to hold attention and arouse 

 discussion. 



Particularly during the laet ten or fifteen yeara when 

 tbe principles of plant physiology bare been more and 

 more satisfactorily applied to plant production and man- 

 agement baa lntereat aettled In pruning. During the 

 latter half of tbla time also more and more Invest! 

 gallons and testa have been conducted by experiment 

 atatlona and other workers to teat out metboda and 

 principles In the interest of aclence and for tbe benefit 

 of growers. The accumulation of iuch new knowledge 

 baa become Tery considerable especially In tbe last de- 

 cade, but it la necessarily ao acattered that Tery few 

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

 which ahall present the really Important features of 

 these Investigations as well aa set forth the fundamental 

 principles baaed upon tbe laws of plant growth. 



This volume Is lavishly Illustrated mainly by actual 

 pbotographa of specimens which show good and bad 

 practicea. The author has apared neither time nor ex- 

 penae In gathering hla photographs, each one of wblch 

 tells its story. 



After a few pagea of introduction the author discusses 

 Plant Physiology as related to pruning A chapter 

 takea op the Philosophy of Pruning, Itself a very ln- 

 tereatlng subject. Then follows a classification and clear 

 discussion of Buds, very fully Illustrated from life. How 

 Wounda Heal la an exceedingly Interesting chapter, as are 

 alao thoae on Prevention and Repair of Mechanical In- 

 juries, Pruning Nursery Stock, Young Trees, Mature 

 Treea and Odd Methods of Pruning and Training, Re- 

 juvenating Neglected Treea 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.
