lighthouses; but their structure, and great distance from the
sea, are sufficient refutations of these absurd hypotheses.

PERILOUS ASCENT OF THE PYRAMID OF CEPHREN.

The upper part of this pyramid is still covered with the original
polished coating of marble, to the distance of 140 feet from the top
towards the base, which makes the ascent extremely difficult and
dangerous. Mr. Wilde, in his "Narrative of a Voyage to Madeira,
Teneriffe, and along the shore of the Mediterranean," published in 1840,
made the ascent to the top, and thus describes the adventure:

"I engaged two Arabs to conduct me to the summit of the pyramid--one an
old man, and the other about forty, both of a mould, which for
combination of strength and agility, I never saw surpassed. We soon
turned to the north, and finally reached the outer casing on the west
side. All this was very laborious to be sure, though not very dangerous;
but here was an obstacle that I knew not how the Arabs themselves could
surmount, much less how I could possibly master--for above our heads
jutted out, like an eave or coping, the lower stones of the coating,
which still remain and retain a smooth, polished surface. As
considerable precaution was necessary, the men made me take off my hat,
coat, and shoes at this place; the younger then placed his raised and
extended hands against the projecting edge of the lower stone, which
reached above his chin; and the elder, taking me up in his arms as I
would a child, placed my feet on the other's shoulders, and my body flat
on the smooth surface of the stone. In this position, we formed an angle
with each other; and here I remained for upwards of two minutes, till
the older man went round, and by some other means, contrived to get over
the projection, when, creeping along the line of junction of the casing,
he took my hands, drew me up to where he was above me, and then letting
down his girdle, assisted to mount up the younger, but less daring and
less active of the two. We then proceeded much as follows. One of them
got on the shoulders of the other, and so gained the joining of the
stone above. The upper man then helped me in a similar action, while the
lower pushed me up by the feet. Having gained this row, we had after to
creep to some distance along the joining, to where another opportunity
of ascending was offered. In this way we proceeded to the summit; and
some idea may be formed of my feelings, when it is recollec
