In irrigating trees the first year after planting, two furrows, one 

 on each side of the row, and about 2 feet away from the trees, are 

 usually found the most suitable means for supplying the water to the 

 best advantage. During the second and third years successively, how- 

 ever, the furrows may be ploughed according to the root extensions 

 further and further from the trees to encourage the roots to radiate and 

 extend their pasturage sufficiently. 



Plate 167. — The Irrigationist at Work on the Two-furrow 

 System of Watering. 



Plate 167 illustrates the irrigationist at work and employing the 

 two-furrow method of watering large trees. In this case the water 

 enters the furrows through a break in the bank of the supply channel 

 as indicated by the arrow. 



This was the old mode of liberating the water, but the more modern 

 method of discharge is by the employment of a narrow outlet box placed 

 in the channel bank. The box may be made of galvanized iron or wood, 

 and should be of sufficient length to allow it to protrude about 1 2 inches
