Running lines for Irrigating Ditches.—How far to go up acreek in order to bring water out upon a given piece of land is a ques-tion which frequently arises in individual practice. There is also LOCATING DITCH LINES 205 doubt as to how much fall sliould he giveu to tlic ditch. The fallrequired by a ditch or canal depends upon the amount of water whichit is desired that it shoidd discharge, and upon the width and depthwith which it is intended that the water should flow. It may also bedependent upon the character of the soil in which the ditch is to beconstructed, and upon the peculiarities of the water itself. A strongcurrent in soft soil may cause mischievous erosions. Water carryingmuch sediment must never be allowed to move sluggishly, as clear £. A homemade leveling instrument. water sometimes may. ft is best to state the recjuirements to a compe-tent engineer and act on his suggestion, or secure the counsel of aneighbor who has had experience with similar soil and water. Having decided what fall to give the ditch, the nearest point atwhich water can be taken out of the creek to be brought to a certainpiece of land is found by commencing with the point at which thewater is to be delivered (generally the highest point of the land to beirrigated), and running up stream a line which has the inclinationintended for the ditch. To stake out this line when no special hindrances are in the way,use a homemade leveling instrument constructed as follows: With sound, straight-edged lumber a triangle is made, as indicated in thesketch.
