In ouv last Kumbcr, in descriliing the Patent Drain Pipe, we alluded to tlii- Boring Machine, which is the most important part of the Pdlent, as it enables the drain pipes to be inserted wilh facility, which, without it, would be a very troublesome affair. The Patent Bering M^ichine, shown in the annexed engrav- ing, tig. li is worked by two men turning the handle wJiich gives the rotarv motion ; the advanc- ing motion is given by another man, who leans on a lever, which is represented in a perpendicu- hir position; this when pressed downwards propels a pinion wheel, which advancing up the rack, impels a collar, and, by means of a thumb-screw, clips the boring rod passing through it. Double racks are used for the sake of obtaining a steady motion. The action of the auger may be very advantageously used for brick work ; it cnts out a com- plete cylinder of brick, and thus brings out a solid core. No other tool has been found to produce such a result. Augers and drills of every shape had been tried by the patentee be- fore he hit upon this. Fig. 2 is a front elevation and section of the retaining wall in the cutting of the London and Birmingham Railway between Euston Square and Camden Town; at the back of the wall is that dilEcult soil, the London clav, which has given so much trouble in consequence of being occasionally saturated with water; the clay has now yielded to the influence <if the" ventilation, by the introduction of the drain pipes, inserted at the back of the wall, as shown in engraving; they are inserted to the distance of IGft. from the face of the brickwork. When the pipes were introduced, it was found th^it there were very few spring:* in it, but a considerable accnmuhition of rain wa
