If it is desired to store supplies of tree seed from year to year it is kept in sacks or jars, in a cool, dry place, protected from rats and mice.

Where seed is sown directly on the ground, poison bait must be scattered over the area in order to destroy the gophers, mice and chipmunks which otherwise would eat the seed.

Sowing seed broadcast on unprepared land has usually failed unless the soil and weather conditions were just right.
For the most part, setting out nursery seedlings has given better results than direct seeding.

Two men can set out between five hundred and one thousand trees a day.
The National Forests contain about one million acres of denuded forest lands.

Much of this was cut-over and so severely burned before the creation of the forests that it bears no tree growth.
Some of these lands will reseed themselves naturally while other areas have to be seeded or planted by hand.
