HORTICULTURE. 741 



Orchard management, C. I. Lewis (Oregon Sta. Bui. Ill, pp. 96, figs. ^1). — 

 This is a popular treatise on fruit and nut growing in Oregon. Consideration 

 is given to ttie adaptability of the State to fruit growing, clearing and pre- 

 paring land, planting operations, intercropping and fillers, tillage, cover crops, 

 shade crops, fertilizers, mulching, irrigation, pruning various fruits, orchard 

 rejuvenation, thinning, dwarf fruits, varieties for various localities, the home 

 orchard, pollination, winterkilling, frost and frost fighting, budding and graft- 

 ing including also walnut grafting and nursery grafting, and protection from 

 rodents and sunscald. 



The appendixes contain a bibliography on fruit culture and a list of fruit 

 growers' associations in Oregon. 



Orchard heating-, C. G. Woodbuky and J. W. Weixington (Indiana Sta. Bui. 

 154, PP- 71-96, figs. 17). — This bulletin describes a comparative test of various 

 coal- and oil-burning orchard heaters conducted in May, 1911. Since the tem- 

 peratures were not sufficiently low to destroy the fruit blossoms, the data 

 secured have to do with the comparative value of the heaters rather than with 

 the crop saving effect of the heat developed in these tests. 



At the price quoted for oil and considering the slow and unsatisfactory per- 

 formance of the coal heaters in the test, the oil heaters appear to be preferable 

 for use in Indiana. The effective burning time of the heaters is about 4 hours, 

 or considerably less than is usually advertised. Considering the necessity of 

 a reserve of extra heaters for emergency, fuel supply for several successive 

 nights, and cost of labor, the initial investment to prepare for protecting a 

 10-acre orchard from frost injury is estimated at about $500. 



The authors conclude that in the vast majority of Indiana orchards spruying, 

 pruning, and good management mu'st become a rule instead of an exception 

 before orchard heating will pay. 



Orchard heating-, C. G. Woodbury and J. W. Wellington (Indiana Sia. Bnl. 

 154, popular ed., pp. 3-8, figs. 7). — A iwpular edition of the above. 



Lime and sulphur solutions, G. E. Stone (Massachusetts 8ta. Circ. 31, pp. 

 .}). — A popular circular based upon the literature on the subject relative to the

 fruit diseases. 



Pedigreed nursery stock, U. P. Hedrick (Xcw York State Hta. Che. 18, pp. 

 8). — A discussion of this subject in support of the author's contention that there 

 is nothing to gain in the purchase of nursery stock sold with a pedigree. 



Popular fruit growing-, S. B. Green (St. Paul, Minn., 1912, 4- ^d., rev., pp. 

 328, figs. 132).— In the present edition of this work (E. S. R., 21, p. 546) some 

 rearrangement of the subject matter has been made in order to conform more 

 closely to the usual plan of teaching fruit growing in American schools and 

 colleges. 



Suggestions for growing home finiits, A. B. McKay (Mississippi Sta. Bui. 

 l-'f6, pp. 17). — This bulletin contains ixtpular suggestions for the planting and 

 care of home fruits, including orchard and bush fruits, grai)es, and strawberries. 



Fruits of the Hawaiian Islands, G. P. Wilder (Honolulu, 1911, rev. cd., 

 pp. 2//7', pis. 121). — This work comprises descriptions and illustrations of the 

 indigenous and naturalized fruits of the Hawaiian Islands. 



Marketing horticultural products, P. Work (Penn. Dept. Agr. Bui. 202. 

 1911, pp. 35, pis. 34). — In this popular treatise introductory considerations deal 

 with the imiwrtance, history, complications, and general principles of market- 

 ing. The methods practiced by successful horticulturists are then discussed 

 under the general headings of preparation, transportation, and disposition. 



A short bibliography on the subject is ai)pended.
