Show I HOW THE PYRAMIDS WERE BUILT Theory That Explains Expenditure of Time and Labor. No one has been able to decide how the enormous stones in the pyramids were handled; for, even allowing for the vast army of men, some sort of mechanical contrivance must have been used. On theory is that as each course of stone was laid a sand embankmenl was built around it with long, easy slopes so that the stones for the next course could be pushed on rollers and slid into place, without any actual lifting, and so on, the pyramid being in fact buried as fast as it was built, until the top was reached, when the stupendous job of removing the sand embankment was commenced. This might account for tbe vast army of laborers used; for instance, it is said that in building the great pyramid of Cbeops 100,000 men were employed for 30 years, although the quarry fiom which I he stone was ob lained was nearly 3.000 feet from thr-pyramid. thr-pyramid.
