T/ie horizontal auger (.fig. 663.) is another boring instrument employed in particular cases. ItWas invented bv Halford, of Hathern, in Leicestershire, but is little used. The advantages of it are, intome cases, considerable, bv lessening the expense of cutting, and performing the work in a much shortertune Where a drain or water-course to pass under i bank, road, hedge, wall, rivulet of water, or for Book III. EMBANKING. 7)3 drying marl-pits, &c, it may be used to advantage in excavating a sufficient passage for the water, withoutopening a trench. In laying leaden pipes lor the conveyance of water, it is also useful in making a hole ga ??-???! ihiiiii. in which the pipe may be laid, without opening a cut on purpose. For tapping springs, or finding water atthe bottom of a hill, either for the supply of a house, or for draining the ground, it may likewise be usedwith success ; as the water of the spring, when hit on, will flow more easily and in greater abundancethrough a horizontal or level, than through a perpendicular outlet 4318. The manner of using it is this : — Suppose a lake or pond of water, surrounded with high banks, tobe emptied, if the ground declines lower on the opposite side, find the level of the bank where the per-foration is to be made. There smooth the surface of the ground so as to place the frame nearly level withthe auger, pointing a little upwards. It requires two men to turn t
