540 EXPERIMENT STATION RECORD. 



text is accompanied by a large uumber of illustrations which, together with 

 the descriptions, it is hoped will serve as a standard for the different bean 

 varieties. 



Introductory statements deal with the botanical relationship of bean species, 

 the principles of classification, history of varieties, rules for desci'iptiou, and 

 an explanation of the various characters referred to in the accompanying 

 descrijitions. 



Celery culture, W. R. Beattie (New York, 1907, pp. X+143, pi. 1, figs. 59). — 

 This book treats of the production of celery for home use and for market, In- 

 cluding the selection of soil, production of plants, methods of cultivation, har- 

 vesting, packing, marketing, and uses. Consideration is also given to the selec- 

 tion of varieties for various purposes, the profits derived from celery culture, 

 and seed production. The information given is based upon practical experi- 

 ence, together with observations of the methods employed by the most success- 

 ful growers. The text is fully illustrated. 



The best fruits at the beginning' of the twentieth century (Rev. in Jardiii, 

 21 (1901), Xo. Ji90, p. 22J).— The National Horticultural Society of France 

 has prepared a list of 250 fruit trees, which is intended as a guide for the selec- 

 tion of tlie best varieties. These are arranged in alphabetical order and the 

 name, synonym, origin, and detailed descriptions of both tree and fruit are 

 given. 



Some little-known edible native fruits of the United States, II. H. Rusby 

 (Jour. N. Y. Bot. Gard., 8 (1907), No. 92, pp. 175-188).— A popular lecture on 

 this subject delivered at the New York Botanical Garden, ,iu which the author 

 gives a descriptive account of a large number of our native fruits which at the 

 present time are little used for food purposes but many of which it is believed 

 are amenable to great improvement by modern methods of tre.ftment. 



Investigations on the dropping of young fruit, A. Osterw alder (Landw. 

 Jahrb. Schiceiz, 21 (1907), No. 5, pp. 215-225, figs. 12). — The opinions of sev- 

 eral investigators with regard to the causes leading to the premature dropping 

 of the fruit are briefly considered and an account is given of the author's in- 

 vestigations to determine whether or not the seed of such fruif is fertilized be- 

 fore dropping. 



The seeds of a large number of pears and apples of both fallen fruit and 

 fruit picked from the tree were examined. From the tabulated results it appears 

 that there is comparatively little difference between the number of seed and 

 embryos formed in the fallen fruit and in fruit which remains on the tree, from 

 which the author, draws the conclusion that the dropping of young pears and 

 apples does not stand in direct relation with the previous fertilization of these 

 fruits. 



Some figures are given illustrating the comparative development of self- 

 dropped pears and jiears plucked from the tree. In each case the normal pears 

 appeared to be much better developed. 



A treatise on citrus culture from seed to fruit, \V. E. Masters (Agr. Jour, 

 Cape Good Hope, SO (1907), Ao.s. 2, pp. 155-172; 3, pp. 307-325; J,, pp. .',37-.',53; 

 5, pp. 605-630; 6, pp. 751-763, figs. lit). — From his investigations of several 

 years' duration in the propagation of citrus trees in South Africa, the author 

 has elaborated a system of budding and grafting which is designated the 

 "Masters training system." "Training," as this system is also called, is based 

 primarily on the influence of the stock on the scion, which influence the author 

 claims to have discovered quite by accident but to have further verified by his 

 own work, together with a study of the results unwittingly secured by other 

 orchardists.
