Influence of manure on the yield of winter wheat and the beets following, 

 S. L. Frankfurt (Khoziaistvo, 1909, Nos. 18-20; ahs. in Zhur. Opytn. Agron. 

 {Russ. Jour. Expt. Landw.), 11 {1910), No. 2, pp. 236-239). — The experiments 

 were begun in 1902 and the present article reports the results obtained in 

 1906-1908. 



Manure to the amount of 13,360 lbs. per acre gave a marked increase of the 

 yield of winter wheat, but larger quantities of manure were no more effective. 

 Of the mineral fertilizers only superphosphate was helpful. Simultaneous 

 applications of manure aud mineral fertilizers gave higher yields than those of 

 either manure or mineral fertilizers separately. Manure introduced under the 

 preceding winter cereals increased both the yield of the beets following and the 

 percentage of sugar in them. Mineral fertilizers acted similarly but did not in- 

 crease the percentage of sugar as much as manure. Mineral fertilizers directly 

 applied under beets increased both the yield and the sugar percentage of the 

 beets more than the application of manure to the preceding winter wheat. 



Mineral fertilizers under summer wheat at the Poltava Experiment Field, 

 S. Tretyakov {Batsion. Udobr., 1909, No. 6; ahs. in Zhur. Opytn. Agron. 

 (Russ. Jour. Expt. Landw.), 11 {1910), No. 2, p. 21,2).— It is pointed out that 

 Kulomzin phosphorite does not exercise any influence on the forest loam of the 

 Poltava Experiment Field when applied under winter wheat and the following 

 summer wheat. Manure under the same conditions increases the yield. 



Results of seed tests for 1910, F. W. Taylor {New Hampshire Sta. Bui. 

 lJf8, pp. 187-209, figs. 2). — The text of the New Hampshire law of 1909 regulat- 

 ing the sale of agricultural seeds is followed by a discussion of its object, a 

 statement of the germination standards for seeds of different crops, and direc- 

 tions for submitting samples for test. 



Tables give the results of purity and germination tests of 238 samples of seeds 

 examined during the first 6 months of 1910. Among these, the average germi- 

 nation of field corn found was 10 per cent below the standard. Peas and beans 

 were also below the standard but the average for sweet com was practically 

 up to standard. 



HORTICULTURE. 



A practical treatise of how to grow flowers, fruits, vegetables, shrubbery, 

 evergreens, shade trees, ornamental trees. — Plant pests, diseases and reme- 

 dies. C. H. Tritschler and W. D. Buchanan (Nashville, Tenn., 1910, pp. 167, 

 pis. 2). — The purpose of this work is to present to the amateur a concise knowl- 

 edge of each subject embraced. 



Up-to-date truck growing in the South, J. R. Davis (Atlanta, Oa., 1910, pp. 

 188, pi. 1, figs. J/O). — A practical treatise representing largely the experience of 

 the author but including special chapters by experts on the culture of a number 

 of crops. 



[Horticultural work at the Canadian experiment stations], W. T. Macoun, 

 R. Robertson, J. Murray, A. Mackay, W. H. Fairfield, G. H. Hutton, and 

 T. A. Sharpe (Canada Expt. Farms Rpts. 1910, pp. 128-l-',3, 155-157, 327-329, 

 S72-S79, 1,03-1,13, US-U6, 458-468, 486, 487, 504-511, pis. 7).— This is the custom- 

 ary report on the condition and character of fruits, vegetables, flowers, and orna- 

 mental shrubs tested during the year at the different experimental farms in 

 Canada. The data are quite similar to those found in previous reports (E. S. R., 

 22, p. 338). 



A large number of seedling apples. 3 seedling plums, and a seedling goose- 

 berry received at the Central Farm for examination are described. Eighty-nine 

 additional A-arieties of the seedling apples which were originated on the farm 

 fruited during the year,, 14 of which are here described as being of considerable
