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.

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 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.
