different sizes ; one is usually of large size, and the others grade 
to bulbs of the size of a kernel of popcorn. 
The experiment mentioned above in connection with the dis- 
cussion of blind tulips was also planned to determine the per- 
formance of sister bulbs of different sizes and especially those of 
the smaller sizes. The weights of the various sister bulbs (each 
set graded according to weight) and the subsequent performance 
of these bulbs for the two varieties tested are indicated in the 
following table:

It will be noted from the weights given that bulbs of Rose Gris- 
delin made a more vigorous growth than did those of Cottage 
Maid. This is indicated by the greater weight of first bulbs, the 
greater number of sister bulbs, and, of course, the greater total 
weight, 
The performance of bulbs of smaller sizes of Rose Grisdelin 
is of special interest. Of the 35 second bulbs, the largest of 
which weighed only 13 grams, 28 bloomed ; of 33 bulbs of third 
rank, weighing from 1 to 10 grams, 12 bloomed; of the 18 of 
third rank 3 bloomed, and out of 6 of fifth rank 2 bloomed. 
Bulbs weighing as little as 2.5 grams (a gram equals 0.035 ounce) 
Produced flowers. Flowers from bulbs of smallest sizes were 
small and often poorly developed. The flowers of bulbs of sec- 
ond rank were nearly always fine flowers, but were somewhat 
smaller than flowers of first bulbs, the stems were slightly shorter
