turner for the making of carpenter tools and such 
like instruments. The chestnut makes railroad 
ties that are thought to have no equal and tele- 
graph poles of requisite strength and straightness. 
Then there are other families that have their 
valued representatives. The hickories have al- 
ready been referred to. The maples must not be 
overlooked, as they furnish highly prized white 
woods to the cabinet maker. The tulip tree sup- 
plies a light-colored wood used by cabinet maker 
and coach builder. The basswood or linden gives 
a wood of peculiar fiber that meets the needs of 
carvers and instrument makers. The willows and 
their allies; members of the birch family; the 
buttonwood tree or sycamore; and the locusts and 
their allies are other native trees that are of value 
as they stand and are well worth developing. 
The plant experimenter who works with these 
different trees, being guided by their botanical 
affinities, but making careful tests even where he 
doubts the possibility of hybridization, will be 
almost certain to have his efforts rewarded by the 
production of some trees of new varieties that will 
not only duplicate the unexpected qualities of the 
hybrid walnuts, but will doubtless also reveal un- 
predicted traits that will give them added value. 
Patience will be required in carrying out the 
work, for the tree is long-lived and experiments
