de of wooden strips orlaths one-half inch thick by 2 inches wide and 3 feet long. Four ofthese are nailed together, forming a square spout. The strips cost $6a thousand, or 0.6 of a cent each. It costs 1.1 cents to make eachspout. This makes the cost of each 3.5 cents. If a man sets 50 in aday they will cost in place 6.5 cents each. Placed 4 feet apart therewill be 330 in a length of 80 rods, making the spout system cost $21.15for each 80-rod line. With furrows 80 rods long this will serve 10acres, making the cost about 54 cents per acre. When set they mustbe well puddled in. The quantity of water which is passed throughthem is regulated by a piece of lath or a shingle placed vertically inthe ditch against the end of each spout. The best work can be doneby having the head ditches at short distances from each other, enablingthe owner to save water and irrigate with greater ease and efficiency. U. S.

Fig. 2.—Wooden Head Flume. i 61 One of the best irrigators near Sunnyside, Wash., has this to say uponthe subject: I made two serious mistakes when I started to improve my 40 acres. I did notuse a sufficient number of drop boxes in my head ditches and I placed the ditchestoo far apart. I attempted at first to make one head ditch serve a length of 80 rods,but it was too far to run the wTater profitably in the irrigating furrows. THE IRRIGATING FURROWS. Furrows are run down the slope from the spouts. The practice ofirrigators varies much with respect to their depth and distance apart.Some land wets up more easily and speedily than other land, givingrise to the difference in furrowing. One point to be particularly notedin irrigating by this method, so careful farmers tell us, is to have thefurrows carry as nearly full as possible without breaking over thesides. One successful irrigator says: I run my furrows as full as they will hold until the water gets half way across thefield, then
