different arrangement would be required. See fig. 65. 

 The water would be taken from the supply canals and 

 diverted into a feeder to be carried in a diagonal direction 

 across the plot, from which the distributing furrows

would be carried. The overflow from the distributing 

 furrows would even spread over the ground down the in 

 clination. The triangular spaces below the junction of 

 the distributing furrows with the feeders, are watered by 

 means of small reflex furrows, which gather some of the 

 overflow from the distributing furrows and carry it back 

 toward the feeder. 



This system of irrigated meadows is applicable to 

 numerous and varied circumstances. It may be adopted 

 in cases where the surface is level, or where the inclina-

tion is slight but regular, and where the supply of water 

 is not sufficient to permit of flooding or may be in mini 

 mum quantity. It may also be adopted in those cases 

 where the surface is a plane of which the slope is moder 

 ate in one direction, so that the distributing furrows may 

 be carried on a level, and in a nearly straight direction ; 

 or upon nearly all surfaces which will admit the use of a 

 mowing machine. It is particularly adapted to many
