138 EXPERIMENT STATION RECORD. 



" The wheat plant also takes up its principal plant food, nitrogenous and min- 

 eral matter, at the greatest rate in the young stages and at a decreasing rate as 

 growth proceeds. The highest percentage of moisture in the green plant is 

 found in the first series. The heads of the wheat gain more uniformly and rap- 

 idly in their amount of dry matter than any other part. Nitrogen-free extract 

 is produced and stored at a greater rate than any other constituent, but nitro- 

 gen, ash, and ether soluble matter are added in some quantity also. Fiber is 

 practically all formed by the time the blossom has fallen and remains constant 

 to ripening. 



" The wheat stalks contain their maximum amount of dry matter at blos- 

 soming time, after which they pass some of this material along to the ripening 

 heads. Nitrogenous substance and nitrogen-free extract appear to be the con- 

 stituents which the stalks yield up to the heads. The wheat roots and stub- 

 ble increase in dry matter up to the milk stage, after which it decreases in 

 amount, being passed along to the plant above ground. Fiber present in the 

 roots does not decrease in amount but nitrogenous and ether soluble material, 

 ash, and nitrogen-free extract pass out of the roots into the growing plant 

 above ground during the ripening of the heads." 



[Fibers from Papua (British New Guinea) and India] (Bui. Imp. Inst. [So. 

 Kensington^, 10 (1912), No. 2, pp. 214-210). — This report includes analyses and 

 valuations of cotton, sisal hemp, Sida fiber, Sida rhomUfoUa, and Indian jute. 



The use of sulphur in the cultivation of turnips and beets, A. Magnien 

 (Jour. Soc. Nat. Hort. France, Jf. ser., llf (1913), Jan., pp. 54-56). — Experi- 

 ments are here cited, in which sulphur scattered in the row at the rate of 2 to 

 3 gm. per meter at planting time apparently doubled the yields. 



Bean growing in eastern "Washington and Oregon, and northern Idaho, 

 L. W. Fluharty (U. S. Dept. Agr. Farmers' Bui. 561, pp. 12, figs. 5).— This 

 describes cultural methods, with suggestions on marketing, uses, and improve- 

 ment of the crop. 



Field trials on the manuring of carrots, E. E. Stokes (Midland Agr. and 

 Dairy Col. Bui. 5, 1912-13, pp. 38-45). — It is concluded that " farmyard manure 

 may profitably be supplemented with chemical fertilizers; salt applied to the 

 description of soils generally used for the production of carrots is beneficial, 

 especially in a dry, hot season; potash in some form is absolutely necessary, 

 especially when dung is not so largely used ; phosphates come next in order of 

 importance ; and the addition of nitrogenous manures may be advisable to pro- 

 mote a good start and early growth." 



Clovers, M. Calvino (Estac. Agr. Cent. [Mexico] Bol. 69, 1912, pp. 92, pis. 

 44). — This bulletin treats of the climate, soil, rotations, inoculation, fertilizers, 

 cultivation, harvests, and methods of conserving the crop and silage in relation 

 to the clovers Trifolium pratense, T. repens, T. alexandrinum, T. soaveolens, T. 

 incarnatum, and T. hyhridum. Various methods of rotation in which clovers 

 are used as green manures are described. 



Crimson clover, A. E. Grantham (New Jersey Stas. Circ. 28, pp. 4)- — This 

 gives suggestions and directions for growing the crop under New Jersey condi- 

 tions. 



Effect of frost on com, J. B. Lindsey (Massachusetts Sta. Rpt. 1912, pt. 2, 

 pp. 67, 68). — Chemical analysis of frosted corn revealed little new, excepting 

 that the fiber percentage seemed to be larger than is usually the case. " In 

 case the corn is intended for the silo, the quicker the crop is ensiled the better. 

 If the crop is not to be ensiled, it may be allowed to stand uncut for a week 

 or two." 



Seed selection of Egytian cotton, T. H. Kearney (U. S. Dept. Agr. Bui. 38, 

 pp. 8). — In this bulletin the author discusses the importance of keeping the
