given, through the application of which it is believed material for the study 

 of morphological and biological varietal forms of grains may be secured. 



Cereal and leguminous crops, M. P. Cavalcante (O Brasil: Suas Riquezas 

 'Naturaes; Siios Industrias. Rio dc Janeiro: Ccntro Indus. BrasU, 1908, Por- 

 tuguese ed., vol. 2, pp. 277-319). — The methods of culture practiced in Brazil 

 and the general condition of the industry are described. 



Report on tests with varieties of oats and barley at Garforth, 1907, 

 E. S. Seton {Univ. Leeds and Yorkshire Couneil Agr. Ed. [Pamphlet] 71, 1907, 

 pp. 13). — The best varieties of white oats as determined by tests since 1900 

 were Abundance, Waverley, Tartar King, and Storm King. For rich land Tar- 

 tar King and Storm King, two stiff sorts, are recommended and for land in a 

 lower state of fertility. Abundance and Waverley. Of black varieties. Excel- 

 sior proved the best. 



Taking both yield and quality into account, Standwell barley has proved the 

 best on the average for the past 7 years, being closely followed by Goldthorpe, 

 Brewers Favorite, and Chevalier in the order stated. 



The water requirement of beets, rye, and barley on loam soil in 1907, 

 C VON Seelhorst {Jour. Landic, 56 (1908), Xo. 2, pp. 195-198, pi. 1 ; abs. in 

 Chem. Zentbl., 1908, II, Xo. 7, p. 631). — This is a continuation of observations 

 on the amounts of water evaporated and used by plants during their period of 

 growth ( E. S. R., 18, p. 629). It was found that 1 gm. of dry matter in barley 

 required 504.5 gm. of water, in rye 307 gm., beets 461.S gm. For the production 

 of 1 gm. of dry matter in grain 1.225.7 gm. of water was required in case of 

 barley and 854.2 gm. in case of rye. 



The water requirement of lupines in the fall of 1906 and of potatoes, 

 summer barley, and rye in the summer of 1907 on sandy soil, C. von Seel- 

 KOKST (Jour. Landic, 56 (1908), Ao. 2, pp. 199-207; abs. in Chem. Zentbl., 1908, 

 II, Xo. 7, p. 631). — For the production of 1 gm. of dry matter in lupines 402 to 

 424 gm. of water was required, in potatoes 491 to 829 gm., summer barley 562 to 

 583 gm., and rye 763 to 1.093 gm. 



The water content of grain furnished the German army from the crop 

 of 1906 {Arch. Dent. Landw. Rats, 32 (1908), pp. 1,85-506, dgms. -J).— Tables 

 are given showing the extreme differences in the water content of rye, oats, and 

 wheat for each month from October to March, inclusive. 



Recent observations on the culture of serradella and lupines on heavy soils, 

 B. Heinze (Jahresber. Vcr. Angew. Bot., 5 (1907), pp. 161-199, pis. 4, fig. 1). — 

 It was found that serradella and lupines, although typical plants for sandy 

 soils, developed well under certain conditions on heavy soils and gave yields 

 only slightly less than crops grown on sandy lands. A high lime content in a 

 friable loam did not act injuriously upon either crop. Botli made a poor growth 

 after potatoes, oat.s, mustard, peas, and beans, and apparently had not produced 

 any root nodules. On the other hand, a very good development was obtained of 

 lupines following sernidella and of serradella after serradella. These results 

 were secured without any inoculation of the seed or soil. 



Pure cultures were very effective in inoculating serradella on Lauchstedt soil 

 in pot experiments, and gave better results in this regiird than inoculation with 

 soil in field tests\ Inoculation with pure cultures in field experiments became 

 effective rather late in the growth of the crop when numerous nodules appeared 

 on the roots, but no increase in yield as compared with uninoculated serradella 

 was obtained. The same results were secured with lupines where these had not 

 been preceded by any leguminous crop. 



In one field test where serradella was grown for the first time and no legu- 

 minous crop had immediately preceded it, inoculation with soil from an old ser- 

 radella field was most effective in causing the production of nodules on the roots
