"May 21.--Started at 5.45 A.M. till 8.45; again, at 1.45 P.M.
till 7 P.M.; again, at 9.30 P.M. till 4 A.M. Saw two gazelles,
the first living creatures, except the crows at Moorahd, that we
have seen since we left Korosko; there must be a supply of water
in the mountains known only to these animals. Thermometer, 111
degrees Fahr. in the shade; at night, 78 degrees. The water in
the leather bottle that I repaired is deliciously cool. N.B.--In
sewing leather bottles or skins for holding water, no thread
should be used, but a leathern thong, which should be dry; it
will then swell when wetted, and the seam will be watertight.

"May 22.--Started at 5.30 A.M. till 9.30; again, at 2.15 P.M.
till 7.15 P.M. Rested to dine, and started again at 8.30 P.M.
till 4.25 A.M.; reaching Abou Hammed, thank heaven!

"Yesterday evening we passed through a second chain of rugged
hills of grey granite, about 600 feet high, and descended through
a pass to an extensive plain, in which rose abruptly, like huge
pyramids, four granite hills, at great distances apart. So
exactly do they resemble artificial pyramids at a distance, that
it is difficult to believe they are natural objects. I feel
persuaded that the ancient Egyptians took their designs for
monuments and buildings from the hills themselves, and raised in
the plains of Lower Egypt artificial pyramids in imitation of the
granite hills of this form. Their temples were in form like many
of the granite ranges, and were thoroughly encased with stone.
The extraordinary massiveness of these works suggests that Nature
assisted the design; the stone columns are imitations of the date
palms, and the buildings are copies of the rocky hills--the two
common features of Egyptian scenery.
