PLANTING 33 



to lay one straight row along one side or down the 

 middle of the tract, straightening it by careful 

 sighting and spacing the trees accurately by re- 

 peated measurements. For making these measure- 

 ments nothing is better than a light wooden pole 

 carefully cut to the required length. 



When the first long row is properly staked out a 

 cross row should be established at right angles to 

 it, and this cross row spaced and staked with the 

 same care. From these - so rt. - -/ 



two base lines the remain- poll 



der of the field may be laid 



off rapidly and with very 



little trouble, unless indeed 



the ground is very rough 



and, hilly. 



The best way to do this 

 is to take two light poles S 



cut to the length and the 

 breadth of the tree spaces, 

 say 20 feet each if the 



trees are to stand 20 x 20 , u 



feet, or 20 and 32 feet 



respectively if the trees "«■ i*-how to lay off land 

 are going in at 20 x 32 feet. Place these poles on the 

 ground as shown in Figure 14 with one pole against 

 the second tree in the base row and the other ended 

 against the second tree in the cross row. Then 

 bring the two free ends of the poles together, and 

 where they meet at the point, d, is the place for the 

 next tree. Set a stake here, move the poles for- 

 ward, using this point, d, as a starting point for the 

 next measurement, and proceed as before. After 

 a row of stakes has been set in this way the layout 

 should be gone over again, carefully sighted, and
