ing the hardness of texture of its parents, as the 
hybrid walnuts do, the tree thus produced would 
by itself go far toward solving the problem of 
re-forestration. The oaks quite frequently hy- 
bridize in a state of nature. 
Granted a producer of soft white wood such as 
probably can be made by combining the white pine 
with some of its allies; a producer of hard cabinet 
wood such as a hybrid between the British oak and 
the American white oak would probably consti- 
tute; and the hybrid walnuts already in existence 
as producers of woods of the hardest and finest 
texture for cabinet purposes—granted further 
that the other new trees have the capacity for 
growth which the hybrid walnuts show—and a 
triumvirate of trees would be attained that could 
be depended on to go forth and gladden the de- 
vastated hillsides and valleys with trees that would 
jointly meet every need of carpenter and cabinet 
maker, adding incalculable billions to the wealth 
of our nation. 
And of course we need not by any means con- 
fine attention to these few most typical trees. 
There are beeches and chestnuts that are near 
relatives of the oak, each of which serves its own 
particular purpose as the provider of wood having 
unique quality. The beech, for example, is prized 
by the chair maker for his furniture, and by the
