hand, this method is wasteful of seed because a large proportion
fails to germinate and the young seedlings often succumb to adverse
conditions, so that where seed is scarce or its cost high, planting
is the more practical method.

Because planting is the most reliable method it has been the one
most largely employed in extensive operations, both here and in
most European counties, but thorough tests are now being made of
direct seeding and under proper conditions it promises to be fairly
satisfactory. The Douglas fir region west of the Cascade Mountains
offers the most favorable conditions for direct seeding and except
on badly exposed south slopes, or where the growth of brush is
exceedingly dense, it is believed this method will prove a satisfactory
one for the timber owner to employ.

In the yellow pine regions conditions are not so satisfactory for
direct seeding, since this tree occurs largely in a region of deficient
rainfall. However, natural reproduction is abundant throughout
many portions of this type, and it is probable that direct seeding
will prove fairly successful if the proper methods are employed
and if forest conditions have not been too greatly disturbed. That
some method of successfully employing direct seeding with yellow
pine be found is greatly to be desired, since yellow pine seedlings
do not withstand transplanting well, but there is need for careful
experimentation before extensive seeding operations in this type
by private timber owners would be justifiable.

Western white pine, it is believed, will be easy to reproduce in
most of its native situations by direct seeding, though the greater
scarcity of its seed and the fact that it will be more subject to
