750 EXPERIMENT STATION RECORD. 



Varieties of winter cereals, Tribondeau (Jour. Agr. [Paris'], 1S98, II, No. 1675, 

 pp. 1026-1030). — Brief descriptions are given of a number of different, varieties of 

 winter grains. The results of several fertilizer experiments in connection with the 

 tests of these varieties are reported. 



Report on experiments carried on at Kloster Hadmersleben in 1897-98 with 

 different sport varieties of grain, F. Heine (Ueut. Landw. Presse, 25 (1S9S), No. SI, 

 p. S6S). 



Notes on the culture of wheat (Queensland Agr. Jour., 3 (189S), No. 6, pp. 399-410, 

 pis. 3). — Notes on seeding, harvesting, and stacking wheat. Descriptions of a num- 

 ber of varieties of wheat and barley are given. 



Natural cross fertilization of oats and "change of seed,'' T. Jamieson (Proc. 

 Agr. Research Assoc. [Scotland], 1897, pp. 31-50, fig. 1). — This article is a discussion 

 of the practice of changing seed and a report on experiments in natural cross fertili- 

 zation of oats. The terms high breeding, cross breeding, mongrels, and natural and 

 artificial crossing are defined. From the results of the experiments the author con- 

 cludes that oat plants cross freely when grown side by side, that the wind is a suffi- 

 ciently effective pollen carrier for this purpose, that naturally crossed seeds produce 

 heavier plants than seeds that have not been so crossed, and that crossing may be 

 accomplished on a large scale by mixing the seeds of 2 varieties or differentiated 

 strains and then sowing the resulting seeds the following year. 



Cross breeding of wheat {Queensland Agr. Jour., 3 (1S98), No. 5, pp. 335-33S).— 

 Notes on the objects and methods of cross breeding wheats with regard to the 

 requirements of good milling wheats. 



The wheat-growing capacity of the United States, E. Atkinson (Pop. Sci. Mo.f 

 54 (1S9S), No. 2, pp. 145-162). 



The mineral requirements of grain and the fertilizer applications in spring, 

 L. Grandeau (Jour. Agr. Prat., 1899, I, No. 1, pp. 12-14). — A popular article dis- 

 cussing the utilization of plant food by grain at different stages of growth and its 

 relation to fertilizers applied in spring. 



Field experiments with fertilizers in 1895, Edler (Jour. Landw., 46 (1S9S), No. 

 4, pp. 349-365). — This article is a review of the results obtained from work begun by 

 the late Dr. Liebscker, of Gottingen. Cooperative fertilizer experiments were con- 

 ducted with a view to determining the fertilizer requirements of cultivated soils and 

 the results obtained by the different experimenters are here reported. The author 

 states that owing to lack of uniformity in the conditions no conclusions can be drawn. 



Experiments with nitrogenous fertilizers on hoed crops, G. Dusserre (Chron. 

 Agr. Canton Taud, 11 (1898), No. 23, pp. 668-672).— The results of experiments with 

 nitrogenous fertilizers on fodder beets are reported. The yields were profitably 

 increased, the amount of dry matter in the beets remained the same, the proportion 

 of protein was considerably increased, and the sugar content slightly diminished. 



Box experiments, J. D. Kobur (Meded. Prafistat. Oost Java, 3. ser., 1S9S, No. 7, 

 p. 11). — An account of experiments with different fertilizers on sugar cane, including 

 detailed analyses (fertilizing constituents) of the canes and blades and sugar con- 

 tent of the canes. 



Residual effects of fertilizing oats and clover, sown together, with Thomas 

 slag and superphosphate (Deut. Landw. Presse, 25 (1898), No. 91, p. 957). — The land 

 on which the tests were made received a general application of nitrate of soda. The 

 application of Thomas slag and superphosphate furnished 36.84 lbs. of citrate-soluble 

 and 26.59 lbs. of water-soluble phosphoric acid per morgen (0.63 acre), respectively. 

 The Thomas slag plats gave somewhat better yields of oats than the superphosphate 

 plats, and the following year the Thomas slag plats also produced the largest yields 

 of clover. The differences in the yields of clover were much more marked than the 

 differences in the yields of oats. 



Curing cigar tobacco, R. S. Nevill (Queensland Agr. Jour., 3 (1898), No. 5, pp. 

 342, 343). — Instructions for curing cigar tobacco and directions for packing tbecured 

 product for the market.
