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 

 "heeling in." (Fig. 29.) The 

 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 m 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

Fig. 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.
