The point where the descent was made had been so well chosen that the Jules Verne almost struck the apex of the Great Pyramid as it approached the bottom. The water was somewhat muddy from the sands of the desert, and the searchlight streamed through a yellowish medium, recalling the "golden atmosphere" for which Egypt had been celebrated. But, nevertheless, the light was so powerful that they could see distinctly at a distance of several rods.
The pyramid appeared to have been but little injured, although the tremendous tidal wave that had swept up the Nile during the invasion of the sea before the downpour began had scooped out the sand down to the bed-rock on all sides.
Finding nothing of particular interest in a circuit of the pyramid, they turned in the direction of the Great Sphinx.
This, too, had been excavated to its base, and it now stood up to its full height, and a terrible expression seemed to have come into its enigmatic features.
Cosmo wished to get a close look at it, and they ran the submersible into actual contact with the forepart of the gigantic statue, just under the mighty chin.
While they paused there, gazing out of the front window of the vessel, a bursting sound was heard, followed by a loud crash, and the Jules Verne was shaken from stem to stern. Every man of them threw himself against the sides of the vessel, for the sound came from overhead, and they had an instinctive notion that the roof was being crushed down upon them.
A second resounding crash was heard, shaking them like an earthquake, and the little vessel rolled partly over upon its side.
"We are lost!" cried De Beauxchamps. "The Sphinx is falling upon us! We shall be buried alive here!"
A third crash came over their heads, and the submersible seemed to sink beneath them as if seeking to avoid the fearful blows that were rained upon its roof.
Still, the stout curved ceiling, strongly braced within, did not yield, although they saw, with affright, that it was bulged inward, and some of the braces were torn from their places. But no water came in.
