destruction by birds and rodents because of its larger size may
make planting the more practical method.

Trees for planting can either be purchased from commercial nurserymen
or grown in nurseries established for that purpose near the planting
site. When only a few thousand trees are needed it is cheaper to
purchase them, but when extensive operations are contemplated,
covering hundreds of acres in which millions of trees will be needed,
it is far preferable for the owner to grow the trees in his own
nursery. Some initial outlay for the establishment of the nursery
will be necessary and a practical nurseryman should be employed,
but the saving in the cost of the trees will fully compensate for
these.

One, two and three year old trees, the latter once transplanted,
are usually employed in planting, the older trees being used for
the less favorable sites. In planting they are placed in rows
equidistant apart, the spacing varying from 4 to 12 feet, with a
general average of about 6 feet. The work may be done either in
the fall after growth has ceased or in the spring before growth
commences.

The cost of planting, of course, will vary greatly with the age of
the trees, the number planted per acre and the accessibility and
character of the planting site. With young trees and wide spacing,
the cost may be as low as $6.00 per acre, while in more unfavorable
situations where older plants are used and planting is more laborious
it may be as high as $16.00. A fair average, however, for those
areas which a timber owner would be most likely to plant up is
about $8.00 to $10.00 per acre.
