34 EXPEEIMENT STATION EECORD. 



of buckwheat. A close relation was found during' the seasons of 1908-9 be- 

 t\A'een the yield of grain and straw and the height of the plants. 



Schabdar clover, L. Tkabut (Bui. Agr. Algerie et Tunisie, 16 {1910), No. 18, 

 pp. 434-436, figs. 2.)— The author gives a brief account of tests of Schabdar 

 clover {TrifoHum suaveolens) grown from seed obtained from this Depart- 

 ment. The tests seem to indicate that it is well adapted to the rotation of the 

 country and is more resistant on the high plains than berseem {Trifolium 

 alexandrinum). 



Fermentation in the hay rick, B. N. Wale and H. C. L. Keable (Jour. 

 Southeast. Agr. Col. Wye, 1909, No. 18, pp. 52-55, figs. 2).— Samples of clover 

 hay were weighed at harvest time and later after remaining in hop pockets in 

 the upper, middle, and lower portions of a rick. The average percentage of 

 loss due to fermentation was 15.87. The results of a similar experiment with 

 meadow hay have already been noted (E. S. R., 23, p. 2.36). 



Com secrets, P. G. Holden (Philadelphia, 1910, pp. 19, figs. ii2).— This is 

 a manual of general information for the corn grower. It gives directions for 

 the selection, preparation, and planting of seed and the cultivation of the 

 crop, and suggests means of combating insect enemies. Experimental data 

 already noted (E. S. K., 24, p. 33) are summarized and conclusions drawn 

 from them. 



Corn growing in Louisiana, V. L. Roy (Univ. Bui. La. State Univ., n. ser., 

 11 (1911), No. 2, pp. 5}, figs. 25). — Studies of the corn plant and the status of 

 com growing in Louisiana and the South are accompanied by detailed direc- 

 tions for the production, harvesting, and storing of a corn crop. 



The chemical composition of the different parts of the corn plant, I. 

 Weiseb (Kiserlet. Kozlem., 13 (1910), No. 6, i)p. 7 3 4-7 4S).— 'Hie author re- 

 ports the results of chemical analyses of the tassel, leaves, husks, the cob and 

 kernels combined, and three divisions of the stalk. 



Uniform distribution, of the seed in planting compared with a varied 

 distribution (Queensland Agr. Jour., 25 (1910), No. 5, p. 213).— Hogue Yellow 

 Dent corn was planted in hills 3 ft. 8 in. apart each way during 1907-8. Each 

 year 4 plats were planted with an average of 3 kernels per hill variously dis- 

 tributed. The uniform distribution gave slightly better results, but " ordinary 

 variation in rate of dropping found in corn planters will have very little and 

 probably no effect on the yield per acre." 



Cotton-growing experiments in Mexico, C. A. Millee (Daily Co)is. and 

 Trade Rpts. [U. S.], 13 (1910), No. 149, p. 1190).— The consul reports that the 

 first cotton crop grown in the vicinity of Columbus, Tamaulipas, yielded a bale 

 or more per acre. The boll weevil caused no trouble but the army worm did 

 some damage. The seed was imported from Georgia. 



Cotton crop of Peru, C. A. Miller (Daily Cons, and Trade Rpts. [U. S.], 13 

 (1910), No. 149, p. 1190). — Estimates by the director of the Lima experimental 

 station are reported on the production and exportation of cotton and cotton seed 

 and its products during 1909-10. The cost of producing native cotton is placed 

 at 2J cts. per pound. Of the entire crop production, 05 per cent is American 

 Upland, 32} per cent Peruvian, and 2} per cent Sea Island and Mitafifi. 



Notes on hops, E. S. Salmon (Jour. Southeast. Agr. Col. Wye, 1909, No. 18, 

 pp. 337-359, pis. //).— Earlier work has already been noted (E. S. R., 23, p. 337). 

 Tables present studies of the relation of the number of seeded and seedless 

 bracteoles to the length of hop. The seeded hops excelled in length by from 

 i to f in., although the structure was the same. The increased length " would 

 mean an increase of some 5 or 6 cwt. per acre," secured by planting male hops 

 which flower at the same time as the general crop. The smaller hops contain
