excavation was man's handiwork, applied to a fault in the hard rock. A
sort of natural shaft existed, and this had been extended by manual
labor. Beyond the entrance the cave became more lofty. Owing to its
position with reference to the sun at that hour Jenks imagined that
sufficient light would be obtainable when the tropical luxuriance of
foliage outside was dispensed with.

At present the interior was dark. With the stick he tapped the walls
and roof. A startled cluck and the rush of wings heralded the flight of
two birds, alarmed by the noise. Soon his eyes, more accustomed to the
gloom, made out that the place was about thirty feet deep, ten feet
wide in the center, and seven or eight feet high.

At the further end was a collection of objects inviting prompt
attention. Each moment he could see with greater distinctness. Kneeling
on one side of the little pile he discerned that on a large stone,
serving as a rude bench, were some tin utensils, some knives, a
sextant, and a quantity of empty cartridge cases. Between the stone and
what a miner terms the "face" of the rock was a four-foot space. Here,
half imbedded in the sand which covered the floor, were two pickaxes, a
