Raising Hugo Masses of Masonry.

Raising Hugo Masses of Masonry.

MISCELLANY

At one of the meetings of the British Association a paper was read on a plan of raising large stones for the purpose of building huge masses of masonry, and which was supposed to be the means employed in building the Pyramids, although the precise method adopted by the mighty builders of the Valley of the Nile was admitted to be a vexed question. The supposition is that the lifting power was applied from below, the stone being raised by a tilting process. One end of the stone would first of all be raised from the ground by means of powerful levers, which might be of considerable length and worked by a large number of men. After getting the stone to the proper height a slab of stone or metal could be inserted and a similar process adopted with the other end of the stone. So, by alternately working at either end, a certain height might be attained. Then, by the use of wedges and rollers, the stone might be got into position. Another method suggested was by means of slightly inclined planes formed of strong timber work or even masonry, working the stenes up on rollers by leverage applied behind. There does not seem to be any suggestion of any direct lifting pow-er applied from the above. The question is certainly one involved in considerable obscurity.
