which the water flows over the intermediate slopes. The canals in this system follow a perfectly level course, and much care is to be exercised to follow the sinuous course of this level across the meadow. A very safe method is to make the lower side of the canal of plank or slips of board, over the edge of which the water will flow without injury to the canal. The cost of this system of irriga-

tion is frequently not more than $10 per acre. The canals need to be but very small ; a furrow that will arrest the flow of water is all that is required, its main ofiice being to restrain the velocity of the water, and to collect it from the numerous streamlets into which it soon gathers, and again spread it in a thin sheet over the whole surface.

Where the surface admits of it, a series of slopes and terraces may be made, which can be irrigated upon this system. See fig. 72. In this case, the slopes may be covered with grass, and the intervals cultivated if desired.

Fig. 72.—SLOPES AND TERRACES.

The water which flows down the slope is caught in the furrow at the foot, and then passes over the terrace on to the next slope. The furrow at the edge of the terrace is needed to retain the water sufficiently to thoroughly irrigate the soil of the terrace, which would possibly otherwise receive less than its share. In this system of irrigation, when the soil is open and porous and the supply of water limited, it will be necessary to puddle the bottom
