738 EXPEKIMENT STATION KECORD. 



This acre was lioed Anynst 21 and September 2, 9, 16, 23, and 30. This field 

 was made cleaner by the treatment than the field which was simply hoed. The 

 cost of this treatment was $12 an acre. 



Weed destruction, C. Beooks {ISlew HampsMre Sta. Rpts. 1907-S, p. 389). — 

 In 1907, wild mustard was successfully destroyed in an oat field by thoroughly 

 spraying with iron sulphate solution when the plants were small. Two lbs. of 

 iron sulphate were used per gallon of water and the solution applied at the 

 rate of 50 gal. per acre. In 1908, equally satisfactory results were secured. 



HORTICULTUEE. 



[Horticultural investigations in Alaska], C. C. Georgeson, R. W. De 

 Akmond, J. W. Gasser, and C. W. PI. Heideman (Alaska Stas. Rpt. J90S, pp. 

 9~lJf, 21-32, 41-.'i3, .'/J, Ji9-52, 56, 65-72, pis. 2).— A progress report on the condi- 

 tion of orchard and small fruits, ornamentals, and vegetables being tested at the 

 Sitka and Rampart stations, of fruits and vegetables at the Copper Center 

 Station, and of vegetables at the Fairbanks Station, together with several 

 reports from settlers relative to the behavior of flower and vegetable seed re- 

 ceived for trial. The subject-matter of this report is similar in character to 

 that of previous reports (E. S. R., 20, p. 142). 



The successful maturing of watermelons at the Hot Springs farm in the 

 Tauaua Valley is reported. These melons are grown on soil surrounding the 

 Hot Springs. The soil, which is heated by the same source as heats the water, 

 is sufficiently warm to permit of the successful culture of such vegetables as 

 muskmelons, squash, tomatoes, and sweet corn. 



Beport of the department of horticulture, B. S. Pickett (New Hampshire 

 Sta. Rpts. 1907-8, pp. 539-51^1). — A brief report on horticultural operations 

 being conducted at the station, including some data on an experiment in pack- 

 ing apples which indicate that New Hampshire apples well graded and ])acked 

 will bring highly remunerative prices. 



Hybridization in horticulture, G. Bellair {URyhrUhttion en Horticulture. 

 Paris, 1909, pp. VI +339, figs. 123). — A treatise on plant breeding, discussing 

 the production of varieties, crosses, hybrids and races, and the practices of 

 crossing and selection. 



Consideration is first given to natural variations relative to the theories and 

 factors of variation, adaptation, and correlation. Artificial variations are then 

 considered, including variations produced by different cultural processes, cross- 

 ing and selection. Lists are given of the principal horticultural hybrids, to- 

 gether with special lists of some orchid hybrids. Mendel's law, the factors 

 involved in the production of the principal variations, the production of varie- 

 ties resistant to parasitic diseases, better fruit varieties, and the improvement 

 of cereals and certain ornamental plants, as well as graft hybrids and crosses, 

 are also discussed. 



Promising new fruits, AV. A. Tai'lor (U. 8. Dcpt. Agr. Yearbook 1908, pp. 

 Ji73--'i90, /j/.s". 9). — Historical notes and descriptions with color plates are given 

 of the following little known or recently introduced fruits and nuts which are 

 considered worthy of attention either for the home garden or ,the commercial 

 plantation : Patten, Bennett, and Williams apples, Augbert and Champion 

 peaches, Eaton raspberry, Peters Mango, Kawakami and Lonestar persimmons, 

 and the Taylor, Kennedy, Hodge, Bolton and Carman pecans.

 (Ztschr. Landw. Versuchsiv. Osterr., 12 {1909), Ao. 8, pp. 601-626, charts J,).— 

 A detailed account, including the tabulated results, is given of a number of 

 demonstration manuring experiments conducted in various vineyards in Gorz-
