"A subway connecting Khephren's Pyramid City to Cheops' Pyramid City has been discovered in the course of recent excavations. This had been cut through the living rock.
More remarkable still, a shaft, 11 yards long, was found tolead from the subway to the heart of the rock. When examined, it was found to end in a chamber some 6 yards by 11 yards.
From one side of it there was a second shaft leading 16 yards farther down into the rock and ending in a hall somewhat larger than the upper chamber, with seven smaller chambers leading from it. In two of these, basalt boxes were found."
