the principal trees should be so chosen that 
they will look better and better the older 
they grow, while present effect may be chiefly 
considered in others which are destined to 
be cut as development progresses. 
Texture changes less with the passage of 
years than form. Color is practically per- 
sistent year after year, but alters from month 
to month ; and this fact should also be borne 
in mind. There are some trees, like the 
yellow- wood, which are of a medium tint 
in the middle of summer, but of a yellowish 
green in spring, and it is unwise to place 
them where during a few weeks they will not 
look well, even if later on they assume a har- 
monious hue. And our brilliant autumnal 
effects should also be more carefully consid-

The knowledge we need to gain, if we are 
to make the best of our opportunities for
