plants in the plat reuialueil yreen until frost, in spite of the fact that the seed 

 was grown on soil that for 4 consecutive years had been badly infested with 

 rust. 



The apparent lateness of the rust-resistant strain of melon is believed to be 

 due to abnormal ripening of the other strains rather than to any real inherent 

 lateness. In order to develop early maturity in the rust-resistant strain, how- 

 ever, arrangements are being made for a cooperative test in which some of the 

 seed will be grown in Canada and the product then tested at Rocky Ford to indi- 

 cate the influence of latitude on early maturity. 



Tomato culture, W. W. Tracy {New York, 1907, pp. X+150, pi. 1, figs. 'iS).— 

 This is a practical treatise on the tomato, including its botany, history, general 

 characteristics, planting, fertilization, cultivaton in garden and greenhouse, 

 harvesting, jiacking. storing, and marketing. Consideration is also given to the 

 adaptation of varieties for different purposes, and to seed breeding and growing, 

 together with chapters on insect enemies and their control by F. H. Chittenden, 

 and the diseases of tomatoes and their control by W. A. Orton. 



A method of propagating fruit trees with, special reference to the olive, 

 DUBOULOZ {Bui. Off. Gouvi. Gen. Algerie, IS {1907), No. 15, p. 252).— The author 

 calls attention to the successful results secured from propagating the olive by 

 what he terms the graft-cutting ( " greft'e-bouture " ) method. This method, 

 which is described, appears to be similar to the long scion root-graft method used 

 chiefly with apples in the western part of the United States, in which the grafted 

 scion is planted up to the top bud and eventually forms roots, being nourished 

 in the meantime by the piece of root to which it is grafted. 



The cherry in the valley of the Rhone, A. Cadoret {Prog. Agr. et Vit. 

 {Ed. I'Est), 28 {1907), Nos. 27, pp. 20-25; 28, pp. J,2-52, figs. 10; 29, 2)p. 86-90; 

 30,^pp. 119-123; 31, pp. 142-1^8). — Popular directions are given for the cultiva- 

 tion of the cherry with special reference to the development of the industry in 

 the valley of the Rhone. All of the important i»hases are considered, including 

 soil and climatic conditions, varieties, soil preparation, and planting operations, 

 pruning, fertilizing, enemies of the cherry and their control, harvesting and mar- 

 keting. Information is also given with regard to yields, financial returns, mar- 

 ket conditious, and the various uses of the cherry. 



New hybrid plum, A. M. Ragland {Farm and Ranch, 26 {1907), No. 20, 

 p. 10, fig. /). — A description, with illustration, is given of a new hybrid plum 

 said to have originated in the orchard of H. A. Biles, of Roanoke, Tex. This 

 ])lum, which has been named Bilona, is believed to have originated accidentally 

 through cross-pollination of the Chabot by a wild plum growling in a neigh- 

 boring forest. It is said to have the form of the Chabot, blooming at the same 

 time, and bearing an immense crop of fruit, which is covered with a crimson 

 blush on a yellow ground and a heavy bloom, characteristic of the Australis, a 

 native wild plum of that section. The tree is said to have an upright and vig- 

 orous growth, and the fruit is believed to be equal in quality to the best plums 

 of Americana or Chickasaw strains. 



Coffee culture in Hawaii, W. H. T'kers {'I'ca and Coffee Trade Jour., 13 

 {1907), No. 2, pp. 67-75, figs 15). — A popular account of the coffee industry in 

 Hawaii, including considerable data with regard to the annual yields, value, 

 acreage, average yield, cost of production, and the estimated yield for the islands. 

 The annual output is given as from 24,UO0 to 30,000 bags exported to the main- 

 land, together with 1,800 to 2,000 bags consumed in the islands. The annual 

 value for the 5 years 1901-1906 ranges from $270,000 to $336,000. The total 

 acreage under cultivation is given as 4,500, the average yield about 650 lbs. per
