THE planter's GUIDE. 



piece of greensward put down in its stead, so that the 

 tree may be dropped with mathematical precision on the 

 spot intended. 



With single trees in the park, this sort of accuracy may 

 sometimes be of small moment : but where a particular 

 effect is to be produced by one tree, or by the combina- 

 tion of several trees as a group, it may be of considerable 

 consequence ; and as it takes up only a moment, the 

 workmen should always be made to practise it. It tends 

 to give them habits of accuracy in their work, and teaches 

 them the value and importance of juxtaposition, when it 

 becomes necesssary to study it. 



Meanwhile the driver, as directed, makes the proper 

 circuit with the horses, (see plate III.,) and brings up the 

 machine as nearly as possible to the north-east side of 

 the pit, running the wheels up against the bank or 

 mound of earth thrown out. Here it is prudent to take 

 off the horses, as it is always safer and better to wheel 

 in the machine, for the two or three last yards, by 

 manual exertion — an object which is readily accomplished 

 by cutting down the mound of earth in front of each 

 wheel, and thereby forming an inclined plane for the 

 descent of the tree into the pit. 



On this occasion it is indispensably necessary that the 

 machine should advance right upon the centre, or piece of 

 greensward deposited in the pit, but without overrunning 

 that point. Two persons, the director and another, then 

 station themselves on the outside of the pit, transversely to 

 each other — the one, we shall say, on the south-west side, 

 opposite the machine, and the other on the north-west or 

 south-east side, whichever may be most convenient — 

 because the line of sight at both of the last mentioned 

 points is equally at right angles with the machine's direc- 

 tion. The workman who is placed immediately opposite
