tions. In fact, the government should control all

introducing undesirable kinds, and with them, also

Long ago Great Britain sent ships to the East 
Indies to gather seeds for planting in her West Indian 
possessions. Many fine fruits and trees have resulted 
from these early importations. 
The collection and preparation of the seeds of 
trees is now an important business in almost all parts 
of the world, and seeds of almost all valued spe- 
cies may be secured at fair prices from our seed-

Many other causes have stimulated the spread of
