 and excessive coverings of snow, the xerophytic varieties seemed the most hardy. 



Portuguese varieties of wheat and their improvement, O. Klein {Landw. 

 JahrJ)., 42 {1912), No. 2, pp. 331-364, pls. 8).— This article gives results of 

 trials of some foreign as well as domestic varieties conducted at Lisbon. 



It was found that in general seeding with the drill at the rate of 15 kernels 

 per square meter, or broadcast from 200 to 250 kernels per square meter gave 

 the best results. 



Complete chemical analyses and yields per hectare of the grain and straw are 

 given for SO varieties, with botanical descriptions, notes, etc., for each variety. 

 The weight of 100 kernels ranged from 3.7 to 6.4 gm. and of 1 liter from 720 to 

 833 gm. The specific gravity varied from 1.294 to 1.390. 



Clover and g-rass seeds, with reference to valuation, and the present status 

 of their production and trade from the local standpoint, A. Boerger (Landw. 

 Jalirh., 42 {1912), No. 1, pp. 1-118, pis. 18). — In a discussion concerning seeds 

 from various countries and localities it is noted that in general, in so far as 

 investigations have been made, seeds have produced better when grown in the 

 locality where planted. 



Considerable space is devoted to the discussion of means of forming and 

 operating organizations to promote the production, use, and trade in a high 

 quality of grass and clover seeds. Tables give data regarding foreign trade 

 in seeds and the home supply and demand. 



Seed tests, L. Hiltnee et al. (Landw. Jahrh. Bayern, 2 (1912), No. 9, pp. 

 636-664). — An article in which results of germination and purity tests of clover 

 and grasses from European sources are given and discussed. 



HORTICULTURE. 



Garden farming, L. C. Coebett (Boston, Chica^go, and London, 1913, pp. 

 X-{-473, figs. 175). — A practical treatise on the intensive and extensive culture 

 of vegetables in which the author presents in considerable detail the results of 

 his own observations and investigations, together with those of other horticul- 

 tural authorities. 



The successive chapters of part 1 discuss vegetable gardening, or olericulture ; 

 the soil as a factor in the work of the market gardener ; principles of planting 

 and cultivation ; forcing and forcing structures ; root cellars and storage houses ; 

 transportation of truck crops ; precooling and cold storage of vegetables ; and the 

 home vegetable garden. In part 2 the commercial vegetables are arranged in 

 alphabetical order and considered with reference to their development, cultiva- 

 tion, and uses. 



Pomology, horticulture, and viticulture, E. Reimers (Jahres'ber. Landw., 

 27 (1912), pp. 229-250). — A review of recent contributions to the knowledge of 

 pomology, horticulture, and viticulture in Germany. 



Report of field work by the horticultural department during 1911, A. L. 

 Dacy (West Virginia Sta. Rpt. 1912, pp. 78-97, figs. 13).— This report reviews 

 cooperative spraying and pruning demonstrations conducted in different sections 

 of West Virginia during 1911. Some suggestions are also given relative to the 

 possibilities of truck growing in the State. As a result, of orchard demonstra- 

 tions greatly increased returns have been reported by the owners.
