‘was a very curious one—to all intents and pur- 
poses a smooth-skinned peach, with white flesh, 
bearing at its core an almond nut. 
Further experiments in selective breeding will 
be necessary to develop the hybrid to a stage at 
which its qualities of flesh and nut respectively 
will give it commercial importance; but the foun- 
dation for such development is supplied in the 
hybrid already secured. This hybrid, it may be 
noted incidentally, is a most remarkably vigorous 
grower. 
An allied series of experiments of equal inter- 
est was inaugurated by hybridizing the Languedoc 
almond and the Muir peach, using, as in the other 
case, the utmost precaution to prevent foreign 
pollenization. 
Many seedlings were grown from this cross and 
a large number of them have been under observa- 
tion for years. 
The most notable thing about these hybrid seed- 
lings from the outset was the tendency of many 
of them to take on rapid growth. Some of them 
grow five or ten times as fast as the average seed- 
lings of either parent. This propensity of hybrids 
to rapid growth is something that we have seen 
manifested in many other cases. It is, indeed, a 
rather common result when species that vary by 
just the right amount are hybridized. The hybrid
