The same was found to be true in regard to molasses. That produced in a 

 dry season, 1911, contained 2.62 per cent of total nitrogen, while in the wet 

 season of 1910 it contained only 2 per cent. 



A comparison of some seedling- sugar canes witli the Bourbon variety in 

 Barbados, J. R. Bovell {West Indian Bui., 12 {1912), No. 1, pp. 357-^60) .—The 

 results of trials covering a period of 14 years are given. These indicate a su- 

 periority of seedlings B 208 and B 147 over the customary White Transparent 

 of from 6.5 to 24.4 per cent. 



Bourbon and seedling canes, J. W. Ajrbuckle (Dept. Agr. Trinidad and 

 Tohago Bui. 11 {1912), No. 70, pp. 30-33). — In this article the author discusses 

 the superiority of seedling canes over the old variety, Bourbon, which has prac- 

 tically succumbed to disease. 



Sugar cane on savanna lands, R. S. Cunliffe (GuM Mag., 4 {1913), No. 10, 

 pp. Jf64-470, figs. 6). — Fertilizer trials at Manacas, Cuba, on light soil hereto- 

 fore considered worthless for sugar-cane culture are reported. 



The plat receiving 200 lbs. nitrate of soda, 214 lbs. dried blood, and 416 lbs. 

 basic slag per acre yielded 55,882 lbs. cane, as compared with 10,770 lbs. on 

 the check plat, and an increased profit of $38.81 per acre. The plat receiving 

 in addition 120 lbs. sulphate of potash yielded 67,973 lbs. per acre, and a profit 

 of $49.87 over the check plat. The plat receiving 300 lbs. sulphate of am- 

 monia, 170 lbs. double acid superphosphate, and 120 lbs. sulphate of potash 

 yielded 62.106 lbs., and a profit of $56.02 over the check plat ,and the plat re- 

 ceiving in addition to this 400 lbs. nitrate of soda, 170 lbs. double acid phos- 

 phate, and 120 lbs. sulphate of potash, yielded 88,576 lbs., and a profit of $61.50 

 over the check plat. 



Analysis of the cane juice showed for the 5 plats a respective sucrose con- 

 tent of 17.7, 19.12, 18.89, 19.02, and 19.08 per cent, and purity coefllcients of 

 89.65, 89.77, 90.82, 92.78, and 91.29 per cent. 



On the manuring of swedes, J. Poeteb {Herefordshire County Cou/ncil 

 Farmer's Bui. // {1910), pp. J^). — In these experiments, larger yields in general 

 were produced with 6 cwt. of superphosphate per acre than with a combination 

 of 4 cwt. of superphosphate and 2 cwt. of bone flour, or 4 cwt. of superphos- 

 phate and 2 cwt. basic slag, but the quality of the roots seemed best with the 

 basic slag mixture. The dressing which gave the greatest yield was ^ cwt. 

 sulphate of ammonia, 6 cwt. superphosphate (30 per cent), and ^ cwt. sul- 

 phate of potash. The addition of potash seemed to increase the yield on an 

 average of 18^ cwt. per acre. 



The inheritance of certain quantitative characters in tobacco, H. K. Hayes 

 {Ztschr. Induktwe Ahstam. u. VererMngslehre, 10 {1913), No. 1-2, pp. 115-129, 

 figs. 8). — The author here gives results of continued work (E. S. R., 29, p. 536) 

 on the inheritance of leaf number in Fs generations of crosses between Sumatra 

 XBroadleaf and Cuban X Havana tobacco. The conclusions drawn are as 

 follows : 



" Number of leaves per plant is a stable character and little affected by 

 changes of environment. The Fi generation is of intermediate value, the mean 

 for leaf number being almost exactly equal to the average of the parental 

 means. The Fi generation is no more variable than the parents. Different 

 variates in Fi give similar results in F2 showing the Fi variation to be of no 

 germinal value. The F2 generation is much more variable than the parents or 

 Fi. Some of the F2 generation breed true in Fs, giving no greater variability 

 than the parents themselves, others give an intermediate variability between 

 that of the parents and F2, and others are as variable as the F2 generation 

 itself. Intermediates as well as extremes may breed true. Of the 3 Fs gen-
