1HE IRRIGATION AGE. 75 



hinged to the upper part of the box will fall down or lie down over 

 the end of the box so that it will form a water-tight joint. Any kind 

 of suitable hinge may be used to fasten the door or trap to the top of 

 the box. The weight of the water will cause the trap to remain 

 closed; if not, a weight may be added. A lever or suitable means 

 may be used to open the trap when the water is to be let into the ditch. 

 The trap end of the box must be on the inside of the reservoir, not on 

 the outside. 



The reservoir should be of suitable dimensions 50x100 feet or 

 100x200 feet, instead of 50x50 feet or 100x100 feet, for reasons herein- 

 after stated. In calculating. the height of wall, measurements should 

 always be made from che outside instead of the inside and from 5 to 6 

 feet in height above the level of the land. 



The water lying in the bottom of the reservoir, below the land 

 level, can not be used because it can not be taken into the ditch. The 

 first foot above the land level is of comparative small value because of 

 the low pressure and the slowness with which it forces the water 

 through the ditch. For these reasons the water should never be al- 

 lowed to be drawn closer than a foot above the level of the outlet of 

 the reservoir. 



Irrigators who employ their reservoirs as a fish pond will find it 

 advantageous to maintain not only the water that lies below the level 

 of the water box, but to allow six inches or a foot of the water that 

 lies above the water box to always remain. By so doing they will not 

 destroy their fish nor the reservoir by permitting it to dry up, or be 

 injured by freezing in the winter. 



It has been suggested by some Irrigators that good results would 

 be obtained by planting around the embankments any variety of low 

 growing bushes for the double purpose of protecting the water from 

 the force of the wind, which disturbs it into waves to destroy the 

 embankments, and to give to the reservoir that pleasing effect so much 

 desired.

WHO BIDES HIS TIME. 

 Who bides his time he tastes the sweet 



Of honey in the saltest tear; 

 And though he fares with slowest feet, 



Joy runs to meet him, drawing near; 

 The birds are hearlds of his cause, 



And, like a never ending rhyme, 

 The roadsides bloom in his applause 



Who bides his time.
