the table, since the facts are quite as well shown by 
stating the aggregate weight for periods of ten days 
each. The division into periods is made for the pur- 
pose of showing comparative earliness. This could 
be shown in a more marked degree by taking the first 
and second cuttings alone, but they were too limited 
in quantity to admit of conclusions being drawn from 
them; hence they are included with the other cuttings 
in the same period.

‘‘’This shows a gain of the male over the female 
plants of seventy-six per cent. for the first period, and 
a fraction less than fifty per cent. for the whole season. 
Reversing the standard of comparison, it will be seen 
that the female plants fall below the male forty-three 
per cent. for the first period, and a little more than 
thirty-three per cent. in the total. In no case did the 
female plants produce equally with the male. 
‘“If comparative earliness is determined by the date 
of first cutting alone, there is no difference between 
the male and female plants, since the first cutting was 
made on both at the same date; but taking quantity 
of product into consideration, which is the proper
