with imliealions that Onlkn among the soft wheats and Harnovka and Epi noir 

 among the hard wheats, are Ix'st adapted to the region. 



Some varieties of barley, inchiding Stoekmannsoder, Minnesota, and English 

 D, matured in 101 days, while several others, Including JNIontana Chevalier, 

 required 114 days. The heaviest grain-yielding A'arieties were Escourgeon du 

 Midi, Bavarian, Hungary, and Chevalier, and the lightest grain-yielding 

 varieties were Svalof, Pedigree, Wisconsin, and I'omelle. The results further 

 showed that Escourgeon du Midi ranked first in stooling capacity and pro- 

 duced the largest number of grains per head, and that Auvergne occupied first 

 place in the weight per thousand grains. 



The blossoming of barley, C. Fkuwirth {Fii1ili)ig's Laiidir. Ztf/.. .To (1906), 

 A'o. 16, pp. o-'i-'i-ooS). — Tile author reports the results of his own observations 

 on the process of blossoming in tlie different kinds of barle.v and reviews the 

 observations made by other Investigators in this same line of work. 



The respiration of barley, O. Qvam (Tidnskr. XorsJcc Landhr., 13 {1006), 

 No. 6, pp. 263-28.^}. — Investigations were conducted to establish the relation 

 between the germination of seeds and the amount of carbon dioxid given off in 

 the process of germination, and to devise ultimatel.v a method by which the 

 more rapid determination of the respiration of seeds might be substituted for 

 germination tests. Similar work by other investigators is described, together 

 with a report on the metliods and the apparatus used by the author. In the 

 tests made it was observed that the quantity of carbon dioxid respired by the 

 seeds increased with the increase in tenqierature and the moisture content of 

 the grain. — f. w. woll. 



The study of corn, V. M. Shoesmith (Kdiisas Sta. Bill. 139. pp. 223-2Ji9, figs. 

 12). — This bulletin is a guide in elementary corn judging. Notes on the his- 

 tory, types, and varieties of corn, rules fm- judging, discussion of ])oints of 

 the score-card, and a description of corn breeding and improvement are given. 



Cotton culture in Korea {Diplo. ami Co».s. Rpts. [London], 1906. No. 65.^,, 

 pp. 11). — A report is given on the rei-iiU of experiments in cotton culture in 

 Korea. It is shown that upland cott.ni i ; apparentl.v well adapted to that 

 country, the crop being considerably lieavier than that of the native plant. 



In a comparison of the 2 t.vpes of cotton the onl.y difference in season 

 observed was in the bursting of tlie pod. which was later in the upland cotton 

 on account of the larger boll produced. T'pland cotton gave a larger yield 

 than the native variety even wlien the buds and superfluous shoots were not 

 pinched out. The upland type not only gav(> a greater percentage of ginned 

 cotton than th# native plant, but the fiber v\-a^'. also longer and finer. It is 

 estimated that about 298,200 acres of cotton are grown i:i Corea, and that 

 this area represents about 4.r> per cent of the total cultivated land of the 

 countr.v. 



Improvement of cotton by seed selection, T. Thornton {West Indian Bill.. 

 7 {1906), No. 2, pp. 133-170). — A general discussion of the subject is given 

 and the work with seed selection in P>arbados during 190r>-r> is described. 

 It is stated that out of 204 plants first Kelcctel in the field only 14 gave 

 satisfaction in all the characteristics exanuued. In determining the qualities 

 of the samples the length of staple, the proportion of lint to seed, the pro- 

 portion of wealv fibers, diameter of fibers, silkiness. and fineness was con- 

 sidered, and the data thus secured are given in a tal)le. 



A test of commercial cultures for legumes, G. C. Butz {PeniiS!jlva)iia Hta. 

 Bui. 7S, pp. 13). — Seed of alfalfa, vetch, so.v beans, and cowpeas innculated 

 with a commercial culture was compared with the same kinds of seed not 

 so treated in flowerpots filled with sterilized sand to which was added a
