Golden Wonder millet {S. italiea) Las very long, tapering heads, with 

 small green or sometimes rose-colored bristles. It is easily aftected by 

 drought, and rather late in maturing. 



Other kinds of millet described are Missouri millet, Oaliforiua millet 

 {Setaria italiea), Italian millet {S. italiea), Japanese millet (S. italiea), 

 Texas millet {Fanicum texanum), sprouting millet (P. proliferuni geni- 

 culatimi), barnyard grass (P. crusijalll), sorgluim {Andropogon sorghum), 

 Johnson grass {A. Italapensc), and pearl millet [Peniiisetum typhoidetim). 



A list of other sjiecies to which the name millet has also been applied 

 is given. Tabulated data give number of seeds per gram, shape and size 

 of seeds, and brief notes on the growth of all samples of millet tested.

 Kkaus and A. Stellwaaci {Ztschr. landic. Va: Baijern, 1891, pp. 164- 

 171; abs. in Centbl. agr. Chcni., 23 {1894), No. 10, pp. 667-070).— A^ the 

 barley grain becomes ripe its composition improves, the percentage of 

 starch increasing and that of nitrogen decreasing. Heavy manuring, 

 when it was accompanied by lodging of the straw, resulted in the for- 

 mation of light grains with a high percentage of nitrogen and a low 

 starch content. Among the barley grains of a single variety those 

 were most glassy which contained a high percentage of protein, but 

 the protein content was not the only factor concerned. 



Caiiaigre, E. W, Hilciard {California Sta. Bui. 105, pp. 1-9). — 

 This is largely a resume of all investigations heretofore published by 

 the stations which have tested tiiis crop. It api)ears that the decider 

 the tint of the foliage and the root the larger the percentage of tannin in 

 the root, a fact which suggests possible improvement in cahaigre as has 

 been effected in the case of the sugar beet. A comparison of the prob- 

 able profits in growing black wattles and caiiaigre is given, the result 

 of the comparison being somewhat in fiivor of caiiaigre. The follow- 

 ing table gives the composition of the ash of cahaigre root, and for 

 comparison the composition of the ash of the sugar beet;
