, and Forbes and the Greek were left alone on the empty raft.

After some consideration they decided on the following plan: Forbes and
Canaris would take the raft apart and fasten the rope to the logs. Sir
Arthur and the colonel would draw them up, pull them along the top of
the cliff, and lower them gently to Chutney on the other side, who would
receive them on the ledge, loosen the rope, and throw them down the
remaining fifty feet to the ground, where the soft sand would receive
them without injury.

Guy was speedily lowered to the ledge, where the torch was still
burning. Three more stuck in the crevices served to illuminate the top
of the cliff.

Down in the lake Melton and Canaris quickly severed the withes that
bound the raft together, and in a short time the first log was swung
gently down to Guy, who stood it endwise on the ledge, loosened the
noose, and pushed it over the brink. It fell with a dull crash.

In half an hour the raft was lying at the bottom of the cliff, and then
several alterations were made. Chutney exchanged places with Forbes, and
Sir Arthur, who found himself unequal to the task of pulling the heavy
logs to the top of the cliff and dragging them along the summit, took
the Greek's place, and went down to assist Chutney with the raft.

Sir Arthur and Guy transferred themselves to the canoe as the raft grew
smaller, and when the last log went up they noosed the rope about the
center of the canoe itself and went up hand over hand and joined the
others.

The canoe was pulled up with some difficulty, and lowered to Guy, who
allowed it to remain on the ledge, which, though narrow, was ten or
twelve yards long. The baggage was next lowered, and then, one at a
time, Bildad going first, they descended to the platform where Guy was
awaiting them.

Forbes was the last one down, and, with a dexterous jerk, he threw the
hook loose from above, and it but narrowly missed their heads as it
cleared the ledge and struck the ground. It was dragged back and hooked
in place.

The final descent was not free from accident, for the canoe slipped from
the noose and fell with a crash, but with no other mishap all reached
the solid earth, and with the casting off of the rope from the ledge was
severed the last link that connected them with the underground lake and
its horrors.

A TERRIBLE RIDE.

Their first act showed the true character of these brave men.
