Houses (Transposition Of). The annexed diagram will explain the method by which houses are removed. The building, of course, must be a detached one. Openings are made in the end walls, just above the ground, large enough to insert beams about fifteen inches square across the building (1) ; the end of each beam is supported on blocks of wood, fixed into the ground, and clear of the walls, and each beam made firm and 1ight by driving wedges between the beams and the upright block. "When this has been done, the foundation is cleared away, and a clear space left. Then oilier beams (2) are placed under the first, and resting like them on blocks of wood, and by this means the front and back walls are supported ; and now the whole foundation is exposed. The screws (3) are placed under the ends of the second beams (2), which are forced upwards by their means, and the weight of the whole building sustained by them. The ground underneath being ail removed, a set of grooved-ways, or beams (6), are placed where the end walls formerly stood, and the cradles (5), which are beams with a projection corresponding to the groove in the ways, are placed on them, both being previously well greased. Large beams (4) are placed over the cradles, between them and the beams (2) which support the ends of the house, and wedges driven in to render the whole tight and secure, which is also effected by additional blocks (7)-The screws are now removed, and being placed horizontally, are made to act together against the cradles, and move them along the ways, at the rate of four feet a day, to the place the house is to occupy. Then, by inverting the operations, the beams are removed, and the house firmly fixed, without sustaining any injury, and often without even moving as much as a chair from the house.
