319 REPORT OF THE CONFERENCE ON GENETICS. 
into red and white canes, and “whereas the white cane gave on analysis 
very similar results to the parent cane, the red sports excelled all other 
canes in the station in purity of juice.” 
In order to put the relative merits of the sport canes and the original 
stock to a strictly comparative test, they were planted at the Experiment 
Station, Dodds, Barbados, side by side, in the same field, with other 
experiment canes. 
“The following figures, taken from the report of Messrs. d’ Albuquerque 
and Boyell on the agricultural work carried on at Barbados 1900-2, under 
the direction of the Imperial Department of Agriculture for the West 
Indies, show the results obtained. For comparison, the return of White 
Transparent grown in the same field is also given :

The yield from the sport cane in the experiments exceeds the yield 
from the original stock cane by nearly 2,000 lb. of saccharose per acre. 
This superiority was due to the higher tonnage of the white canes, their 
juice being slightly less rich in saccharose, and slightly less pure than the 
ribbon stock. The juice of both original stock and sport was rich in 
saccharose, and the results, so far, warrant their continued experimental 
cultivation.” ? 
During the season 1903-5, this sport maintained its superiority over 
White Transparent, as may be seen from the following table, which gives 
the mean results for these two varieties obtained from experimental plots 
on black-soil estates, together with the results of a Ribbon Cane, and of a 
Red Sport cane. This latter, as can be seen from the table, has not 
proved satisfactory, but during the last growing season has been very 
vigorous and should give much better results :

Without doubt, these bud varieties deserve much more attention 
than is given to them, both on account of their economic importance and 
also because the study of their variation may yield results of scientific and
