The first reflection we have to make is upon the ease with which 
a good variety can be increased even where we have but a single 
head to work from. The yield in the case above is at the rate of a 
bushel of grain per 45 4 heads, or from 1176 kernels planted: or 
placing it in another form, three seed planted furnished enough seed 
for a bushel of succeeding crop. 
We must note also the effect of the hybridization from which the 
original head planted was the outcome. We have asa crop four 
distinct varieties of grain, between which there are no intermediate 
forms or colors. We have asa total eighteen beardless and eight 
bearded plants, or 271 beardless and 119 bearded heads. We thus — 
see that a cross does not necessarily mean evenness of potency upon 
the part of the parents, and when we consider that there were pro- 
duced four distinet varieties, we must consider that either more than 
one cross was included in the seed, or else that the effect of the cross- 
ing was to bring atavism into play, and to discover several crossings 
of the past. 
~ ¥Seed 13 and seed 25 had really two seed planted: asin either case one seed 
seemed shrivelled and poor, and it was not expected to grow. .
