436 EXPERIMENT STATION EECORD. 



A variety test of sweet potatoes is reported and the diCPerent varieties are 

 described. 



Beport of the Aligarh Agricultural Station of the United Provinces of 

 Agra and Oudh, for the year ending June 30, 1911, A. E. Parr {Rpt. Aligarh 

 Agr. Sia. United Prov. Agra and Oudh, 1911, pp. 6+II). — Earlier work at 

 this station has already been noted (E. S. R., 24, p. 142). 



In each of a number of tests cotton of the white-flowered type gave larger 

 yields than that of the yellow-flowered type. Variety tests of wheat, sugar 

 cane, and peanuts are also reported. There was little difference in the yields 

 of sorghum sown broadcast and that planted after the plow in rows 1 ft. apart. 



Variety selection of hoed crops and leguminous plants and the methods 

 of variety testing, K. von Rijmker (Tagesfrag. Mod. Ackerhau, 1911, No. 6, 

 2. ed., rev., pp. 53, pis. 6). — Variety selection with reference to iwtatoes, fodder 

 beets, sugar beets, and other hoed crops, together with leguminous plants, oil- 

 producing plants and maize, is discussed at some length and the value of pre- 

 vailing methods of variety testing is considered. 



The dry matter content in root crops and the best methods of its deter- 

 mination, P. BoLiN (jS:. Landtbr. Akad. Handl. och Tidskr., 50 {1911), No. If, 

 pp. 286-318). — ^The author studied the loss of weight of roots kept in storage 

 from 2 to 60 days, the variation of dry matter content in varieties and individ- 

 ual specimens, the porosity of the roots, the evaporation of water during the 

 preparation of samples, and the degree of fineness of the samples in their 

 relation to the results of dry matter determination in ruta-bagas, mangels, and 

 fodder beets. Analytical results secured in this connection are reported and a 

 description of the methods of analysis recommended is given in German. 



The principal object of the work was to determine whether or not the dry 

 matter content of roots is in correlation with the percentage of tops or with the 

 weight of the roots. The work was done with 5 varieties each of ruta-bagas 

 and fodder beets and 6 varieties of mangels, from 19 to 24 roots being included 

 in each comparison. The results obtained are recorded in tables. 



The data secured indicated a correlation between the percentage of tops 

 and the dry matter content of the roots, although the relation did not always 

 appear in the individual root. The correlation between the dry matter content 

 and the weight in the roots was less regular, and for this reason it is suggested 

 that in sampling root crops quite as much importance be given to an average 

 percentage of tops as to the prevailing average size. 



Manurial and variety tests with roots, G. de S. Baylis {Jour. New Zeal. 

 Dept. Agr., 3 {1911), No. J,, pp. 286-290) .—A table states the results obtained 

 in tests with mangels, swedes, and carrots. The data are tabulated under the 

 heads of soil, cultivation, inter-cultivation, manure, and yield. 



On seed production with forage plants and some related questions, A. 

 Elofson {Sveriges TJtsddcsfor. Tidskr., 21 {1911), Nos. 3, pp. 127-164; 5, pp. 

 257-301, pis. 4, figs. 10). — The author discusses seed production in Sweden, and 

 describes the production of grass, clover, and alfalfa seed in other European 

 countries. The seed improvement associations, possibility of the exportation 

 of seeds from Sweden, and the preparation of seeds are also discussed. 



Report of an experiment on the renovation of poor pasture land carried 

 out at several centers, T. Milburn and R. C. Gaut {County Council Lancaster, 

 Ed. Com., Agr. Dept., Farmer's Bui. 22, pp. 25, pi. 1). — This work, which was 

 conducted on several farms in different localities, indicated an advantage in 

 the use of wild white clover in preference to ordinary white or Dutch clover in 

 cow pastures. Lime gave decidedly satisfactory results at only one center. 

 Generally the character of the original herbage was only slowly affected where 

 the dressing used was of cob lime, ground lime, or ground limestone. Upon the
