HORTICULTURE. 537 



Cabbage growing in California, S. S. Rogers {California Sta. Circ. 130 

 (1915), pp. 22, figs. 9). — A treatise on the culture of cabbage with special 

 reference to California conditions. The following phases are discussed : Early 

 history of cabbage growing, types and varieties, the cabbage as a truck crop, 

 intercrop, and market garden crop, soils, moisture, climatic requirements, grow- 

 ing and subsequent care of the plants, time of planting and quality of seed, 

 preparation of the field, planting and subsequent care of the plants, harvesting, 

 storing, marketing, cost of production and profits, diseases, and insect pests. 



The inheritance of size in tomatoes, F. E. Peeey {Ohio Nat., 15 {1915), No. 

 6, pp. Ii.l'3-Jt97, figs. 5). — ^This paper reports a study of the inheritance of size 

 in a red currant-yellow pear tomato cross which was made in 1911 and grown 

 through four generations. The literature on character inheritance is briefly 

 reviewed and a bibliography of literature dealing with inheritance is included. 



Summarizing the results of the study as a whole the author finds that a more 

 accurate representation of the size of the tomato fruits can be obtained from 

 their weights than from linear dimensions. The size of fruit of the Fi genera- 

 tion of the currant-pear cross is the geometrical mean between the parental 

 sizes. From an examination of all available data upon the inheritance of fruit 

 size in the Fi generation it appears that when two varieties are crossed which 

 differ widely in fruit size, as in the case of the currant and pear tomatoes, the 

 Fi fruit size will be nearer to the geometrical than the arithmetical mean, but 

 when two parents similar in fruit size are crossed the size of fruits of the off- 

 spring will approach more nearly to the arithmetical than to the geometrical 

 mean. The average fruit size of the F2 generation does not exceed and is even 

 slightly less than the average fruit size for the Fi generation. Fruits of the F2 

 and Fa gnerations agree fairly well in respect to variability and average genera- 

 tion size. F4 fruits show diminished variability and size. 



Arboriculture, L. Savastano (Arhoricoltura. Naples: Francesco Giannini & 

 Sons, 1914, pp. XI -{-848, figs. 268). — This work is essentially a treatise on the 

 principles of fruit and nut growing, with special reference to kinds adapted to 

 Italian conditions. 



Part 1 reviews the history and development of arboriculture. Part 2 contains 

 a census of cultivated and cultivable fruits and nuts and treats in detail of the 

 biologj' of arboriculture, including also information relative to the acclimatiza- 

 tion and geography of fruit trees. The succeeding parts treat in detail of the 

 cultural technique, including propagation, grafting, pruning, manuring, tillage, 

 irrigation, crossing, pollination, and artificial ripening; the establishment and 

 management of orchards, groves, and plantations; and harvesting, packing, mar- 

 keting, refrigeration, storage, transportation, insect pests, diseases and other 

 enemies, orchard renovation, transplanting developed trees, windbreaks and 

 hedges, and orchard valuation. 



A bibliography of literature on the subject is also included. 



A guide to the literature of pomology, E. A. Bunyakd {Jour. Roy. Hort. 

 SoG., 40 {1915), No. 3, pp. 414-449). — In this paper the author describes the 

 more important pomological books of various countries and gives a list of im- 

 portant general pomologies; special monographs on various hardy fruits; gen- 

 eral catalogues and reference works; treatises on grafting and budding, pruning 

 and training, and culture under glass; and general works on fruit growing. 



Small fruits for home and commercial planting, L. F. Sutton {West Vir- 

 ginia Sta. Bill. 149 {1915), pp. 3-38, figs. 18). — In this bulletin consideration is 

 given to strawberries, raspberries, blackberries, currants, and gooseberries with 

 reference to establishing plantations, varieties, culture, cost of production, 

 yields, marketing, returns, and profits.
