on them since the trash and leaves adhere so closely that it is 

 almost impossible to clean them until they are burnt and cut 

 when 18-20 months old. The yield is then 60 or more tons 

 per acre, a large block often averaging 40-50 tons per acre. 

 Henceforward the only tillage done is weeding and moulding 

 for another six months, after which the canes are left to grow 

 on their own. Each estate usually prepares some 1500 acres 

 every dry season for planting " (Morris, *' Cane Growing on the 

 Zambesi '' in the West India Comm. Circ, April 18th, 1921, 

 pp. 165, 166). Other varieties have been tried here, but none 

 have been found to compare with the " Uba " — it is a thin, 

 greenish cane, with long joints and hard rind, contains 14^20 per 

 cent, fibre and 10-14 per cent, sucrose, very hardy, ratoons 

 splendidly, the yield from which, cut after about 12 months* 

 growth, is from 13-30 tons per acre (I.e.). 



The " Lahaina *' cane has given a yield of 4-6 tons, some- 

 times up to 10 tons of sugar per acre in Hawaii (Kew Bull., 1894, 

 p. 419, q,v. for an account of this cane, pp. 418-419), and in the 

 same Island " Dark coloured Bamboo " has yielded 103 tons of 

 cane and 16 tons of sugar per acre and B 208 (already under 

 experiment in Nigeria — see above) has yielded 73 tons of cane 

 giving approximately 12 tons of sugar per acre (Bull. No. 17, 

 Div. of Agric. Hawaiian Sugar Planter's Assoc. ; Agric. News, 

 Barbados, Nov. 3rd, 1906, p. 338). The " Rose Bamboo " cane 

 is in favour in South Formosa, where in 1908 it was anticipated 

 that it would in a very short time entirely displace all other 

 varieties. It jdelds 35 yen per kah (2-4 acres) or say 58,000 kin 

 (77,333 lb.) (Wileman, Cons. Rep. Misc. No. 675, 1909, p. 9). 



The above are but a few of the many varieties that might 

 be grown : but for the others useful reference may be made 

 to " Varieties of Cane, with special reference to Nomenclature," 

 by Noel Deerr & C. F, Eckart, in Inter. Sugar. Journ., Jan. 1909, 

 pp. 29-38; Feb. 1909, pp. 69-76. "Varieties and Races of 

 Sugar Cane " in The Commercial Products of India, by Sir G. 

 Watt, pp. 933-938. '' Varieties/' Kirby & Dudgeon, Bull. Imp. 

 Inst. 1921, pp. 30-33, and the works enumerated below. 



As some indication of the magnitude of the work required 

 the following particulars may be of interest — an estate of 

 43,000 acres in Central Cuba meets the requirements of a sugar 

 factory (built by Messrs. Duncan Stewart & Co., Ltd., of Glasgow) 

 with a capacity for deahng with over 6000 tons of cane per 

 day ; it is intersected by more than 60 miles of railroad, with a 

 full complement of heavy locomotives and cane and sugar cars. 

 The milling plant consists of three trains of 36-inch mills, two 

 trains being 6 ft. wdde and the third 7 ft. wide each with a 

 Krajewski crusher. The steam generating plant consists of 

 24 multitubular steam boilers, each 8 ft. in diam. by 22 ft. in 

 length (Agric. News, Barbados, March 23rd, 1918, p. 89). 

 Another factory — Usine St. Madeline, in Trinidad— is reported 

 to grind the canes grown on seven estates, covering some
