Sugar-cane Experiments in Britisli 

 Guiana. 



XTRACTS have recently been published 

 in the Agricultural Neivs from two 

 reports by Professor Harrison on the 

 j)rogress of sugar-cane experiments in British Guiana. 



On p. 195 some of the results were given of the- 

 experiments carried on in the fields attached to the 

 Botanic Gardens, while the following issue (p. 211)' 

 contained returns of the area under cultivation for 

 the year 1906-7 in British Guiana with varieties of 

 canes other than the Bourbon. 



The former report covers the period July 1, 1905,. 

 to March 31, 1906. During this period some 965 young 

 seedlings were obtained. The season, probably owing 

 to the exceptional dryness of the weather, was not 

 favourable to the production of new varieties. There 

 was a great scarcity of fertile seed, while the cross- 

 fertilization experiments failed completely, no seeds- 

 obtained from them germinating. 



In the experiments in the North field, D. 625- 

 heads the list of the varieties cut as third ratoons- 

 (twelve months old). Its yield was 34'7 tons of canes 

 per acre, with 1'616 lb. of saccharose per gallon of juice. 

 The average yield of these third-ratoon canes was 25'4- 

 tons of canes per acre. B. 147 gave the highest yield 

 among the second-ratoon canes, with 27'8 tons of canes- 

 and 1'635 lb. of saccharose per gallon of juice. The 

 average yield was 22'1 tons of canes. In the South 

 field experiments D. 115 gave the best results among 

 the second-ratoon canes ; D. 145 among the plant canes. 

 The average yields were 18 and 23 tons of canes per 

 acre, respectively. 



Turning to the manurial experiments, it will be 

 observed that there are ' singularly clear proofs of the 

 dependence of the yield of the sugar-cane on the 

 proportion of the available nitrogen added in the 

 manures,' and the experiments, with others previously
