As I have never witnessed the use of the auger in draining, I will give a description of the manner of using it from a competent authority. " Two men," says Mr. Johnstone, " stand above, one on each side of tl>e drain, who turn the auger round by means of the wooden handle; and, when the auger is full of earth, they draw it out, and the man in the hot torn of the drain clears out the earth, assists in pulling it out, and directing it into the hole. The workmen should be cautious, in boring, not to go deeper at a time, without drawing, than the exact depth that will fill the shell of the auger; otherwise the earth through which it is boring, after the shell is full, makes it more difficult to pull out. For this purpose, the exact length of the auger should be regulai'ly marked on the rods from the bottom upward. Two flat boards, with a hole cut into the side of one of them, and laid alongside of one another over the drain, in time of boring, are very useful for directing the rods in going down perpendicularly, for keeping them steady in boring, and for the men standing on when perform- ing the ;* (730.) The principles of Elkington's mode of draining seem to depend on these three alleged facts. 1. That water from springs is the principal cause of the wetness of land, which, if not removed, nothing effectual in draining can be accomplished. 2. That the bearings of springs to one an- other must be ascertained before it can be determined where the lines of drains should be opened; and by the bearings of springs is meant that line which would pass thi'ough the seats of true springs in any g
