in previous years. Propagation of some of tliese hybrids tliut produced the best 

 fruits without caprification was started during the year. 



A small collection of citrus varieties has been planted. Growth measure- 

 ments for 1913 and 1914 are given for the various deciduous fruits and nuts 

 being tested. A very destructive, unidentified disease of the pomegi-anate fruit 

 commonly occurring in the Yuma region has responded somewhat favorably to 

 treatment with Bordeaux. Data are given on variety of tests of onions, 

 tomatoes, and watermelons. 



Most of the ornamental trees and shrubs planted on the test grounds in the 

 spring of 1913 have made excellent growth. Desert gum {Eucalyptus rudis) 

 trees which were frozen to the ground in January, 1913, had an average height 

 of 13 ft. 2 in. and an average trunk diameter of 2.035 in. when measured in 

 November, 1914. Among the herbaceous flowering plants grown in the region 

 it has been found that few, if any, are superior to the chrysanthemum. Data 

 are given on a test of 14 superior varieties of chrysanthemums. Two species 

 of bamboo, Dendrocalamus strict us and Bambos arundinacea, are in the garden 

 and passed through the winter with little frost injury.

Report on the Government Horticultural Gardens, Lucknow, for the year 

 ending March 31, 1915, H. J. Davies {Rpt. Govt. Hart. Gardens Lucknorc, 

 1915, pp. 10). — In addition to the usual information relative to the administra- 

 tion and management of the garden, notes are given on fruit and food-producing 

 trees as woll as other trees and plants of economic value that are being tested. 



The Florida plant act of 1915 (State Plant Bd. Fla. Circ. 1 {1915), pp. 7).— 

 This circuhir contains the text of the Florida law enacted to prevent the In- 

 troduction into and dissemination within the State of insect pests and diseases 

 injurious to plants and plant products of the State and also establishing a 

 state plant board to carry out the provisions of the act. 



Standard insecticides and fungicides v. secret preparations, G. P. Gray 

 {California Sta. Circ. 1^1 {1915), pp. -)). — In this circular the author points 

 out the disadvantages in using secret preparations as compared with the use 

 of standard insecticides and fungicides that have been fully tested by the 

 U. S. Department of Agriculture and the experiment stations. 



Raising cabbage seed, A. E. "Wilkinson {Country Gent., 80 {1915), No. 44. 

 p. 1C54, figs. 3). — The methods employed in raising and harvesting cabbage seerl 

 by a seed grower in X(nv Yorlc State are described. 



Winter rhubarb, culture and marketing, R. Bland {San Luis Rey, Cat.: 

 Author, 1915, pp. 69). — A short treatise on the culture of rhubarb in semi- 

 tropical parts of the United States for shipment to the early spring markets. 



Papago sweet com, a new variety, G. F. Freeman {Arizona Sta. Bui. 75 

 {1915), pp. 453-468, pis. 3, figs. 2).— In the summer of 1910, a number of 

 wrinkled sweet grains were found in ears of two types of common squaw corn 

 grown by the Papago Indians. The smaller type was extremely hardy and re- 

 sistant to worms. The larger type was sweeter but more susceptible to injury by 

 worms and ear molds. The two tj-pes were bred together and the present bulle- 

 tin gives the results of four years' work in breeding and selection. Directions 

 are given for growing sweet corn and the control of smut together with notes by 

 A. W. Morrill on ear worms and tlie corn flea-beetle. 



The first year after the cross was made, the average weight of the ripe ears 

 was about 31 gm. After four years of breeding this weight has been doubled 

 and the size and depth of grains has been materially Increased. As shown by
