a couple of thousand feet was steep enough; but it was formed of
granite rocks all moss-covered, so that the footing could not be
determined, and at short intervals we nearly went out of sight in
holes under the treacherous carpeting. Add to this that stems of
great trees were laid longitudinally and transversely and criss-cross
over and among the rocks, and the reader can see that a good deal of
work needs to be done to make this a practicable highway for anything
but a squirrel....

We had had no water since our daylight breakfast: our lunch on the
mountain had been moistened only by the fog. Our thirst began to be
that of Tantalus, because we could hear the water running deep down
among the rocks, but we could not come at it. The imagination drank
the living stream, and we realized anew what delusive food the
imagination furnishes in an actual strait. A good deal of the crime
of this world, I am convinced, is the direct result of the unlicensed
play of the imagination in adverse circumstances. This reflection
had nothing to do with our actual situation; for we added to our
imagination patience, and to our patience long-suffering, and
probably all the Christian virtues would have been developed in us if
the descent had been long enough. Before we reached the bottom of
Caribou Pass, the water burst out from the rocks in a clear stream
that was as cold as ice. Shortly after, we struck the roaring brook
that issues from the Pass to the south. It is a stream full of
character, not navigable even for trout in the upper part, but a
succession of falls, cascades, flumes, and pools that would delight
an artist. It is not an easy bed for anything except water to
descend; and before we reached the level reaches, where the stream
flows with a murmurous noise through open woods, one of our party
began to show signs of exhaustion.
