The fuller's teasel, W. Dallimore {Roy. Bot. Q<ird. Eew, Bui. Misc. Inform., 

 1912, No. 7, pp. 3JtB-S50; a6s. in Interrvat. Inst. Agr. [Rome}, Mo. Bui. Agr. 

 Intel, and Plant Diseases, 4 (WIS), No. 2, pp. 237, 258).— This article describes 

 the cultivation of teasel in England, the United States, and France. 



The production of bright tobacco by the flue and air curing processes, 

 H. W. Taylor (Agr. Jour. Union So. Africa, g {1913), No. 6, pp. 880-909, figs. 

 22). — This article gires the history of the air and flue curing processes, with the 

 advantages of each, and descriptions and diagrams of various kinds of drying 

 barns. Varieties of tobacco to grow for each of these methods of curing are 

 mentioned, and descriptions given of the best methods to employ in the pro- 

 duction of bright tobacco, including selection and care of seed plants, seed 

 beds, soil and its prexmration and management, transplanting, cultivation, top- 

 ping, suckering, ripening, harvesting, curing, preparation for market, and 

 insect pests. 



Trifolium parviflorum and T. angnlatum, B. Szaetorisz (Kis^rlet. Kozlem., 

 15 {1912), No. S, pp. 782-789). — From an exhaustive study of these annuals the 

 author notes that they grow luxuriantly in wet weather conditions, that they 

 improve the value of pastures where the soil contains an abundance of sodium, 

 but otherwise are failures, that many of the seeds are hard-coated and do not 

 germinate the first season, and that they seem to be immune to the attacks of 

 the dodder. 



Environmental influences on the physical and chemical characteristics of 

 wheat, J. A. LeClebc and P. A. Yodee {U. S. Dept. Agr., Jour. Agr. Research, 

 1 {1914), No. 4, pp. 275-291). — This article continues reports on work begim in 

 1909 (E. S. R., 22, p. 730; 29, p. 835), in which soils from California, Kansas, 

 and Maryland were transported and compared with local soils of each of the 

 3 States and wheat grown on them. 



It is noted " that in about 80 per cent of the samples investigated the weight 

 of 1,000 grains of seed grown on different soils in any one locality was suflS- 

 ciently uniform to permit the conclusion that climate and not soil is the chief 

 factor affecting the size of the grain." It was found that the weight qf a 

 bushel of wheat ran more or less parallel with the weight of 1,000 kernels. 

 In " classifying the grains of each sample into those which were wholly dark 

 or flinty and those which api eared to be light brown or mealy, a remarkable 

 uniformity is found in the groups arranged by locality in which they grew 

 and a dissimilarity in groups arranged by the source of soil." From data 

 obtained " it seems justifiable to conclude that climate is the principal factor 

 influencing the protein content of wheat, and that soils, when used as in this 

 experiment, have little or no influence '" 



It is noted that the fiber content of the kernel varied more widely than either 

 the fat or gliadin, and that a greater influence was exerted by seasonal or cli- 

 matic changes than by di ferences in soils. " The average ash content of all 

 crops grown on each of the 3 soils, irrespective of the locality, showed but 

 slight variation, being 2.13, 2.08, and 2.16 per tent for California, Kansas, and 

 Maryland soils, respectively." In most cases the amounts of potash and of 

 phosphoric acid rose and fell in the same proportion as the ash. 



"Although the relationship or interdependence between the physical proper- 

 ties and chemical constituents does not show in these results as markedly as 

 might be expected, such relationships may be distinctly traced in some of the 

 constituents. Thus, as has often been pointed out by others, a distinct correla- 

 tion exists between the protein content and the physical appearance or between
