  Where furrows have been plowed, it is a simple matter to keep the
crews in line. When furrowing is impossible, it is much more difficult
to maintain straight lines and uniform spacing. One way to insure
straight rows and even spacing is to set three or more poles or guide
stakes in line toward the far end of the first row to be planited, yet
    Set the tree against the vertical face of the planting' hole to
  secure correct depth. Avoid bunching or doubling back of roots.
within full view of the planting crew. One crew should be assigned to
this row, and after beginning, the second crew should be started off
six feet from the first row. A third crew may be strted' six Ieet from
the second row, and so on. Such a system requires that the irst crew
set the pace for all, that it keep in careful alignment with the stakes,
and that each crew pay careful attention to the spacing between the
row it is planting and the row next to it.
Planting the Trees
  Each tree should be planted about one-half inch deeper than it grew
in the nursery. The old soil line can be recognized readily by the
paler colored bark on the stem of the tree. The hole or slit should be
deep enough to care for the entire root system of the tree. The roots
should be spread out in as near a normal position as possible, and par-
ticular care is necessary to prevent the ends of the, roots from being
curved upwards after placing in the hole.
  The soil must be thoroughly packed around the roots of every tree.
No tree should be allowed to dry out while it is being carried on, the
planting job.
