producing strong plants. This variety produces large clusters of seed pods on 

 every flower stem, hence offers opportunities for breeding work. 



Investigations with the Rotundifolia grapes were continued. By forcing a 

 number of varieties to bloom and set fruit out of season, at the same time 

 preventing the male vines from flowering, evidence was secured which indi- 

 cates that varieties of the Rotundifolia grapes are not dependent on the pollen 

 from male vines for the development of normal fruit. It was also found that 

 bees apparently ignore the flowers of the Rotundifolia grapes, hence play little, if 

 any, part in their pollination in the region of the station. 



Variety and cultural tests of fruits and vegetables were conducted by the 

 Pee Dee substation, and also variety tests of fruit at the Coast substation 

 during the year. 



The Lamao Experiment Station, P. J. Westeb (Philippiiie Agr. Rev. [Eng- 

 lish Ed.], 8 (1915), No. 2, pp. 65-80, pl^. ^).— An account of the Lamao Ex- 

 periment Station with special reference to progress made in the various projects 

 since the reorganization of its work in 1913. A brief summary is given of 

 work accomplished on the following projects: Tropical fruits, citrus fruits, pine- 

 apples, avocados, mangoes, papayas, spices, nursery work, tropical root crops, 

 vegetables, seed growing, apiculture, live stock, maintenance, and extension. 



Somatic segregation, E. J. Kbaus {-Jour. Heredity, 7 (1916), No. 1, pp. 3-8, 

 figs. 2). — A paper read before the American Genetic Association at Berkeley, 

 Oal., August 5, 1915. 



The author gives a number of examples of tvvo classes of variations in plants, 

 one of which breeds true while the other does not. The slow progress thus far 

 made in improvement through bud selection is attributed to the failure to take 

 into account the occurrence of both fluctuating variations and constant varia- 

 tions. The work of Shamel with citrus fruits (E. S. R., 34, p. 43) is pointed 

 out as a striking case in which true segregates or mutants appear to have 

 been utilized. 



The garden and farm almanac for 1916, edited by E. L. D. Seymour 

 (Garden City, N. Y.: Doubleday, Page d Co., 1916, pp. 200, figs. 98).— A ref- 

 erence book and annual for the farm, garden, and country home. Among the 

 special features are a monthly calendar of operations, garden and farm building 

 plans in blue print, directories of national organizations having to do with the 

 various phases of agriculture, a state directory of agricultural activities, a 

 bibliography of books and bulletins of 1915 on farm, garden, and country life 

 subjects, coqcise directions for the control of diseases and pests of fruits, vege- 

 tiibles, and ornamentals, a guide to farm and garden weeds, a planting table for 

 vegetables, and information on the more important breeds of farm animals. 



Two farm gardens, C. A. Keffer (Col. Agr. Univ. Tenn., Ext. Div. Pub. 11 

 (1915), pp. 15). — This bulletin contains plans for two gardens, one of a dozen 

 vegetables to be grown on not more than one-fourth acre of land, and the other 

 to include an acre of land devoted to vegetables, small fruits, and orchard 

 fruits. 



The home vegetable garden, H. F. Tompson (Facts for Farmers [Mass. Agr. 

 Col. Ext. Sen'.], 5 (1915), No. 5, pp. 4)- — This pamphlet contains brief prac- 

 tical suggestions for planning and managing the home vegetable garden, in- 

 cluding a vegetable planting table. 



[Experiments in growing vegetable seeds at the Central Experimental 

 Farm in 1915], M. B. Davis (Agr. Gaz. Canada, 3 (1916), No. 1, pp. 12-18, 

 figs. 7). — Experiments in raising beet, carrot, celery, and cabbage seeds, con- 

 ducted at the Central Farm, Ottawa, are reported. Information is given rela- 

 tive to methods of storing and planting the seed stock and harvesting and clean- 

 ing the seed, together with results secured in 1915.
