his colleague replied in triumph. "And now, having demonstrated this important conclusion so that it is clear to anyone, however prejudiced or obtuse, I am of opinion that we cannot do better than break up our camp and travel to westward until we find some means of ascent."
The ground at the foot of the cliff was rocky and broken so that the going was slow and difficult. Suddenly we came, however, upon something which cheered our hearts. It was the site of an old encampment, with several empty Chicago meat tins, a bottle labelled "Brandy," a broken tin-opener, and a quantity of other travellers' débris. A crumpled, disintegrated newspaper revealed itself as the Chicago Democrat, though the date had been obliterated.
"Not mine," said Challenger. "It must be Maple White's."
Lord John had been gazing curiously at a great tree-fern which overshadowed the encampment. "I say, look at this," said he. "I believe it is meant for a sign-post."
A slip of hard wood had been nailed to the tree in such a way as to point to the westward.
"Most certainly a sign-post," said Challenger. "What else? Finding himself upon a dangerous errand, our pioneer has left this sign so that any party which follows him may know the way he has taken. Perhaps we shall come upon some other indications as we proceed."
