PLANTING. 
If trees are shipped from a distance they should be taken at once on 
arrival to some point where the roots may be carefully covered with 
soil; there they should be unpacked and plenty of loose moist earth 
worked thoroughly around and over the roots as fast as they are taken 
from the box. This temporary | 
covering of the roots is called =~. SS. 
“heeling in.” (Fig. 29.) The Se 
tops may be either erect or laid 
almost on the ground in succes- 
sive rows, the tops of one row 
lying over the roots of the pre- 
vious rows, the object being to 
cover the roots thoroughly and 
keep them moist until the tree 
is wanted for permanent setting. 
Not a moment of exposure should be permitted between the box and 
the soil. If the roots appear dry, they may be dipped for a few min- 
utes before heeling in in a tub of water or in thin mud. 
Trees in large quantities are often packed directly in cars with a 
small quantity of straw about the roots. When shipped in this way

Fic. 30.—Trees handled in a careless manner. The roots should have been covered with wet canvas. 
extra care (compare figs. 30 and 31) must be exercised in taking the 
trees to the point where they are to be heeled in. The wagon in 
which they are to be hauled should have a tight box, and wet canvas 
should be tied tightly over the load. The last is important, so that 
there may be no chance for the roots to dry.
