New YorkK AGRICULTURAL EXPERIMENT STATION. 367 
The results in the above table are shown in Plate XVII, fig. 3. 
These figures would indicate apparently a very striking correla- 
tion between specific gravity of seed and vigor of the resulting 
plants; but the writer has not yet separated Swedish turnip 
seeds by sieving and the striking differences shown in this table 
may be found to be due to a grouping of the seeds according to 
size, ' 
CAULIFLOWER. 
The tests with cauliflower did not at first promise results and 
for this reason four heads which did form early in the fall were 
cut and no record was made of their weight. Later, other plants 
came on and their records are given herewith. The variety used 
in this test was Autumn Giant.

* Two other plants in this lot had been cut early in the season. 
It is regretable that all of the plants in this experiment were 
not preserved intact. It will be noticed, however, that all four 
of the plants which were harvested early were from large seed 
of medium or high specific gravity. In one of these groups was 
found the heaviest head, with one exception, of any weighed. If 
a single test like this indicates anything at all, it indicates that 
the largest cauliflower heads are grown from large seeds of 
medium or high specific gravity.
