HORTICULTURE. 539 



Horticulture in Egypt (CUtrd. Vhron., 3. ser., Jf2 (1907), Nos. 1073, pp. U, 

 J/J; J07.'i, pp. 73, 7.'i). — A popular account of tlie extent and methods of cultiva- 

 tion of a large number of tropical and semitropical fruits and vegetables in 

 Egypt. 



Phenology as an aid to horticulture, E. Mawley (Jour. Roy. Ilort. 8oc. 

 [London], 32 {1907), pp. .7J-J7, dgiiia. 3). — The author gives an account of the 

 methods adopted by the Royal Meteorological Society in order to compare the 

 dates of flowering of certain plants in different parts of Great Britain year 

 after year. 



Specimen tablei^ and records are given, together with suggestions for the 

 modification and use of these methods in private gardens. 



Influence of the stock on the scion, G. Riviere (Jour. Soc. Nat. Hort. 

 France, .'/. scr., 8 (1907), Mar., pp. 15S-160). — A summary is given of previous 

 grafting experiments conducted by the author in conjunction with G. Bailhache, 

 in which they found a variation in color, size, and content of sugar, acid, and 

 dry matter with the fruits of both apples and pears when grafted on different 

 stocks. Their recent investigations along the same line, which are noted, appear 

 to demonstrate further that the products of the scion are influenced more or 

 less by the stock. Among the stocks studied for pears the Cognassier appears 

 to exert the best influence on the scion both with regard to increase in size 

 of the fruit and increase in sugar content. Reference is made to a Doyenne 

 d'Alencon pear grafted on a Doucin apple. While the growth of this tree is 

 not vigorous, it is said to be 1.3 vears of age and bore fruit for the first time 

 in 1906. 



The variations or sports which frequently occur among flowering plants, 

 L. Duval (Jardin, 21 (1907), No. Jf89, pp. 198-200).— A discussion of the above 

 subject, in which the author cites numerous instances of the occurrence of 

 variations or sports among many of onr flowering jilants. 



Report of the government horticultural and experimental fields in South 

 Holland for 1906, C. H. Claassen et al. (Vcrslag Rljkstuinbouwproefvelden 

 Zuid-HoUaiul, 1006, pp. 109). — During the season of 1906 over 150 cooperative 

 cultural, variety, fertilizer, and spraying experiments were conducted with a 

 large variety of fruits and vegetables in South Holland under the direction of 

 the professor of horticulture at Boskoop. This pamphlet embraces reports of 

 the various experimenters with regard to the experiments and tests undertaken 

 in the different localities. 



American varieties of garden beans, W. W. Tracy (U. K. Dept. Agr., Bur. 

 Plant Indus. Bui. 109, pp. 173, pis. 2//). — A continuation of previous investi- 

 gations on varieties of vegetables (E. S. R., 14, p. 057; 16, p. 871). 



The author has made an extensive study of the varieties of garden beans 

 listed by American seedsmen. The results of these studies are said to be 

 based largely on variety tests conducted at Washington, D. C, and in various 

 r»laces in the States of Connecticut, New York, Minnesota, Nebraska, Missouri, 

 California, and Washington. 



Beans are said to be sold in the United States under more than 400 varietal 

 names, and to have at least 185 distinct types. A summary is given of all the 

 varieties desirable for home use and the market. A classification with key is 

 also given of practically all of the distinct varieties now listed by American 

 seedsmen, together with a description, comparative notes, synonyms, and history 

 of each. A list is given of nearly all the garden beans catalogued today in 

 America, embracing both distinct and subsidiary varieties, of which the latter 

 have been found upon trial to be strains or duplicates of the distinct types. The
