156 ELEMENTARY FORESTRY. 
clover would come along and probably make a good showing 
the next year. After the oats and clover have started, about one- 
half the land can be planted in strips, not more than sixteen feet 
wide and twenty-four feet apart. If these strips are planted with 
almost any of our hardy trees, they should do well. For this 
purpose the White Willow would be very desirable, but seedlings 
of Boxelder, Green Ash or Norway Pine should also do well. 
The strips of land in oats and clover will afford sufficient protec- 
tion to the planted strips to protect them from wind injury. After 
these strips are established and two or three years old the inter- 
vening spaces may be broken up and planted without danger 
of any further wind injury. 
6. A. has a piece of burned-over timber land on which there 
are scarcely any seed-bearing trees of value; the valuable pines 
have all been destroyed by successive burnings. Most of the 
land is perhaps two miles from any seed-producing White Pine, 
which was the most profitable tree on this land, and is undoubt- 
edly now the most profitable tree that this soil can produce. He 
would like to have it restocked with White Pine. How should 
he go to work to do it? 
Answer: Since the seed-bearing trees are so far distant from 
the land there is no use depending upon them for restocking the 
soil with their seedlings, and the Poplar, Birch and Bird Cherry 
will undoubtedly soon reign supreme here, if they do not already. 
The best treatment is probably to gather White Pine seedlings 
that are under one foot in height from the nearby forest, if they 
can be obtained easily, and set them out, about twenty feet apart 
each way, amongst the brush now found on the land, taking care 
to make a little clearing, as it were, where each tree is planted. 
The tendency will be for the worthless trees now growing on 
the land to smother out the pines before they get started, and 
it will be necessary each summer for several years to go over the 
land and cut away those trees that are crowding the young pines 
too severely. After these young pines have become established 
it is probable that they will be able to take care of themselves 
in competition with the inferior species, and then the crowding 
which they receive from the latter will be a good thing for them, 
as it will cause them to take on an upright growth. Plantings of 
this kind will probably cost somewhere about five dollars per
