directions for some years, in order to provide better material for crossing with 

 thick canes. Ah-eady two such crosses have been distributed for trial on 

 provincial farms. The cane formulae obtained by dissecting plants from 

 six to nine months agree fairly well in the three forms, being very extended. 

 The Dacca plant, at first very backward, became extremely luxuriant at nine 

 months and had many more branches than the others, as can be seen from the 

 figures in the Table. In appearance, these Dacca plants are much more like 

 cultivated canes than the other two varieties. The average length of the 

 basal portions, the average length of joint for the first two feet, and the thickness 

 at two feet from the base, show^ the regular variations met with in the cultivated 

 canes; but, individually, the plants were often irregular in these characters. 

 There is, in Saccharum spontaneum, nothing like the orderly development 

 of the branches which characterizes Saccharum aruiulinaceum.
