48 A MANUAL OF FORESTRY 



Seed is borne prolitically, and being light and equipped with 

 a wing, like ash seed, it is carried considerable distances. The 

 seed germinates easily on light leaf litter or bare mineral soil, but 

 as only a small percentage of the seed is fertile, reproduction in 

 this region is somewhat scanty. It sprouts occasionally from 

 the stump but cannot be considered a vigorous sprouter. 



The tulip has a tender bark and is easily damaged by fire. 

 Although the leaves are sometimes badly infested with a scale 

 insect it has no serious insect or fungous diseases. 



The lumber is smooth, clear-grained, soft, and usually free 

 from defects, hence, easily workable. Known in the market 

 as whitewood, although usually of a greenish-yellow color, the 

 lumber has many uses, as in the manufacture of carriages and 

 furniture, for cheap interior finish, etc. Near the seacoast it is 

 used for piling. 



On account of its rapid growth and its value the tulip is a tree 

 to be encouraged in sites suited to its production.
