Clover and grass mixtures for meadows and pastures, Werner (Mitt. Dent. 

 Landw. Gesell., 14 (1S99), No. 2, pp. 11-15). — This article describes a number of 

 clovers and grasses and points out their adaptability to certain soils and uses. A 

 number of clover and grass mixtures for meadows and pastures on different soils 

 are suggested. 



Cowpea ensilage, T. C. Crenshaw, jr. (Country Gent., 64 (1899), No. 2403, pp.

Kafir corn, C. K. McQuarrie (Florida Ayr., 26 (1899), No. 10, pp. 146, 147).— A 

 popular article on growing Kafir corn in Florida. 



Review of literature on the culture of potatoes, L. Ochapovski (Selsk. Khoz. i 

 Lyesov., 1SS (1898), No. 3, pp. 641-672). 



Variety tests of potatoes in 1898, W. Blumich (Sachs. Landw. Ztschr., n. sir.,

Observations on the yield and starch content of several varieties of pota- 

 toes, A. Girard (Ann. Sci. Agron., 1S9S, I, No. 1, pp. 46-83). — A number of varieties 

 of potatoes were »-rown for 10 successive years and the yields and starch content of 

 each variety for each year are reported. It was found that a dry season decreased 

 the yield but increased the starch content, while a wet season had the opposite 

 effect. The varieties recommended, given in their order, are Richter Imperator, 

 Red Skinned, Idaho, and Geante sans Pareille. 



Importance of good seed in sugar-beet cultivation, II. W. Diederich ( U. S. 

 Consular 1,'pts. 1S9S, No. 218, pp. 451-454). — This article discusses sugar-beet-seed 

 production in Germany with reference to the needs of the American sugar-beet 

 grower, and advises planting seed of high grade and pure pedigree. 



Distance experiments with sugar beets, F. Desprez (Jour. Ayr. Prat., 1899, II, 

 No. 4, pp. 125-127). — It is coucluded that the distance between plants is a direct 

 factor in the cost of producing sugar, but that no fixed rule can be laid down, as 

 different distances are required under different conditions.

 6 (1899), No. 1, pp. 1-4). — A general review of the different methods of growing seed 

 beets, with an outline of a. new method.

 cultivation of sugar cane, with descriptions of varieties.

 12, p. 103). — A discussion of the classification of wheat and an outline of Eriksson's 

 system of the classification of varieties. 



Investigations on the injurious effects of hail on wheat and barley, C. KRAUS 

 (Deut. Landw. I'resse, 20 (1S99), No. 14, pp. 137, 138; 15, pp. 149, 150, Jigs. 4). 



Plowing and harrowing, G. Heuze (Jour. Agr. Prat., 1899, /, Xo. 7, p. 240). — A 

 note on the importance of plowing and harrowing in connection with various crops 

 and rotations. 



The use of the land roller in plant culture, E. Woi.i.xy (Fuhling's Landw. '/Ay., 

 48 (1899), No. 2, pp. 47-50; 3, pp. S5-91).— The results of experiments show that rolling 

 cereal crops after certain stages of development materially decreases their produc- 

 tive capacity, while the effect during the earlier stages of growth was less marked 

 and in 1 instance slightly increased the yield. Rolling the potato crop during the 

 early stages of growth had a beneficial effect, but when the growth of the plants was 

 advanced the results of rolling did not prove conclusive. The effects of rolling the 

 potato crop varied with different seasons. In general, rolling decreased the num- 

 ber of diseased tubers.
