24 THE FOREST TREE CULTURIST. 
The Red and Silver Maple ripen their seeds in spring or 
early summer, about the first to the middle of June in this 
vicinity, and they retain their vitality for only a few weeks. 
If sowed so soon as ripe, they will come up in a few days, 
and make a growth of one to three feet by the time the 
Sugar and Norway Maple seeds are ripe in autumn. 
If Mr. B. had been aware of this fact, he would have 
sent his order for them early in spring, and have directed 
that they should be forwarded to him in bags, or, what is 
better, baskets, but not in close boxes, for when excluded 
from the air, or closely packed together, they will heat, 
and soon be destroyed. These two varieties of maples are 
among the few forest tree seeds that absolutely demand 
immediate planting, and then they grow very readily.
