ON PLANTING. 239 
“Some kinds of trees, as the oak, hickory, and black 
walnut, produce long, carrot-like roots, which penetrate 
the soil to some considerable depth, and they are, there- 
fore, an inconvenient species to transplant if allowed 
to remain in the seed-bed till their roots have fully taken 
hold; and upon this consideration may be determined 
the length of time which may be given them previous 
to removal to permanent sites. In the event of their 
lengthy existence in the seed-bed their roots may be 
exposed to injury on being taken up, in which case they 
are operated on as before described, and all injured parts 
trimmed off smoothly, no jagged wounds being allowed 
to remain attached, as these by their liability to early 
decay retard the thrift of the plant, and, sooner or later, 
convey disease to that portion of the trunk which they 
were designed to support and nourish. 
“Too great attention cannot be given to the subject 
of root-pruning, as upon this operation depends the after- 
vigor of the tree. In any event, whether from injury 
which necessitates it, or on the removal of the plant 
from the seed-bed, the tap-root should be cut off to one 
third or so of its length, or at such a length as will con- 
veniently admit of its being placed in an easy position 
in the soil; this will facilitate, if required, the removal 
of the tree in after-years, besides tending greatly to its 
successful thrift. 
“The following table may be useful to the planter, in 
showing the number of trees that may be raised on an 
acre of ground, when set out at any of the under-men- 
tioned distances :
