In order to set trees in rows, it is necessary to use a garden line (Fig. 96), or to mark out the ground with some of the devices already described (Figs. 113-120); or in large areas, the place may be staked out. In planting orchards, the area is laid out (preferably by a surveyor) with two or more rows of stakes so placed that a man may sight from one fixed point to another. Two or three men work to best advantage in such planting.

There are various devices for locating the place of the stake after the stake has been removed and the hole dug, in case the area is not regularly staked out in such a way that sighting across the area may be employed. One of the simplest is shown in Fig. 139. It is a narrow and thin board with a notch in the center and a peg in either end, one of the pegs being stationary. The implement is so placed that the notch meets the stake, then one end of it is thrown out of the way until the hole is dug. When the implement is brought again to its original position, the notch mark’s the place of the stake and the tree. Figure 140 is a device with a lid, in the end of which is a notch to mark the place of the stake. This lid is thrown back, as shown by the dotted lines, when the hole is being dug. Figure 141 shows a method of bringing trees in row by measuring from a line.

Cutting-back; filling.

In the planting of any tree or bush, the roots should be cut back beyond all breaks and serious bruises, and fine earth should be thoroughly filled in and firmed about them, as in Fig. 142. No implement is so good as the fingers for working the soil about the roots. If the tree has many roots, work it up and down slightly several times during the filling of the hole, to settle the earth in place. When the earth is thrown in carelessly, the roots are jammed together, and often an empty place is left beneath the crown, as in Fig. 143, which causes the roots to dry out.
