offer any sharp contrast. The purity percentage of P.O. .J. 2878 was 
inferior to that of B.H. 10(12) to a leaser extent in the two variety 
trials on fairly compact soils in 1932 than on the friable soil of the

FlGURl 5.— P.O.J. 2878 makes a rapid early growth in the Anasco Valley gran-cultura plantings. P.O.J. 
2878, on the left, is taller than B.H. 10(12), on the right, 7 months old, at Hacienda Esperanza, Central

to be satisfactory (table 14). The sugar in cane was, as a rule, either 
below or barely above 10 percent. In many instances the top por-

enough for acceptance at the mill. 
The general field results of the 1932 crop with P.O.J. 2878 at 
Central Pagan are given in table 21.
