had also an excellent, sweet flavor. The flavor vras considered not quite so 

 good as that of the light-colored type. 



"At maturity the light-colored type showed itself quite true to type, having 

 whitish kernels, red cobs, and large size. There were few yellow dent kernels, 

 probably no more than due to cross-pollination from adjoining plats. The yel- 

 lowish type had smaller ears, mostly white cobs, yellowish kernels, and a 

 larger proportion of yellow dent kernels than the other type. The yellowish 

 type does not have the depth of kernel that the whitish type possesses." 



Cotton, F. Watts (/mp. Depf. Agr. West Indies, Rpts. Bot. Sta. [etc.] 

 Montserrat, 1911-12, pp. 3-6). — This gives brief notes on variety tests of Im- 

 mune, Sakellaridis, and other cottons, and hybrids. 



Economic conditions in the Sea Island cotton industry, W. R. Meadows 

 (U. S. Dept. Agr. Bui. IJfG {liUJf), pp. iS).— This bulletin gives results of 

 inquiries to determine the cause for the low price of Sea Island cotton in 1913, 

 and discusses Egyptian competition, causes of decreased consumption, and con- 

 ditions among the producers of South Carolina, Georgia, and Florida. It 

 places the cause of depression of prices on underconsumption brought about by 

 (1) the deadlock of 1912-13 between spinners and growers; (2) the competition 

 of the Sakellaridis variety; (3) the deteriorated quality of Sea Island cotton; 

 and (4) change in styles and enforced economy of production. 



Notes on the cotton of Cambodia, M. de Flacourt {Bui. Econ: Indochine, 

 11. scr., 11 {191-'i), A'o. 107, pp. 212-21.5).— This gives results of studies of bolls 

 of three varieties of cotton, some of which are three- and some four-celled. The 

 percentage of fiber for a four-celled variety averaged for 20 bolls 32.5 per cent, 

 and for two varieties with three-celled bolls 24.S and 34.8 per cent, respectively. 

 Tabulated data include weight of boll without shell, weight of fiber, and weight 

 of seed. 



Flax from the East Africa Protectorate {Bui. Imp. Inst. [So. Kensington], 

 12 (191J/), No. 2, pp. 211-213). — This article gives data obtained in the exami- 

 nation of samples of flax grown in the Highland districts of the East Africa 

 Protectorate. The fiber merchants in London, who valued the samples, reported 

 very favorably on them, regarding them as superior to Russian flaxes and more 

 comparable with the Belgian kinds. 



Guinea corn {Jour. Jamaica Agr. Soc, 18 {1914), No. 8, pp. 344, 345). — This 

 article records the excellent showing that Guinea corn (durra), especially the 

 red variety, has made in times of drought in Jamaica. 



Hemp, H. H. Cousins {Jour. Jamaica Agr. ^oc, 18 {1914), ^o. S, pp. 334- 

 S36). — This article gives a history of the introduction and cultivation of Agave 

 fourcroides and A. sisalana in Jamaica. The first introduction seems to have 

 taken place about 1855 from Yucatan. 



Better methods of potato production for Iowa, L. Greene^ and T. J. Maney 

 {Iowa Sta. Bui. 149 {1914), PP. 65-81, figs. 3). — The methods here reported con- 

 sisted of spraying experiments, variety tests, selection of best hills as a means 

 of increasing yield, and a comparison of different planting dates as they influ- 

 ence the yield of the main or late crop of potatoes. It is noted that " in 1910 

 six sprayings gave an increase of 61.50 bu. of marketable tubers over the check ; 

 in 1911, five sprayings gave an increased yield of 36.94 bu., and in 1912, seven 

 si)rayings increased the yield 33.6 bu." The estimated cost of spraying with 

 Bordeaux mixture and lead arsenate is $1 per acre. 



Eight varieties of early and 12 varieties of late potatoes are described, and 

 results of yields for 1910, 1911, and 1912 are given that show Prosperity rank- 

 ing first as a late potato and Irish Cobbler as an early variety, with yields of
