Sir Arthur Conan Doyle: The Lost World

Chapter 9: "Who could have Foreseen it?" (continued)

In five miles we saw no rift or break. And then suddenly we perceived something which filled us with new hope. In a hollow of the rock, protected from rain, there was drawn a rough arrow in chalk, pointing still to the westwards.

"Maple White again," said Professor Challenger. "He had some presentiment that worthy footsteps would follow close behind him."

"He had chalk, then?"

"A box of colored chalks was among the effects I found in his knapsack. I remember that the white one was worn to a stump."

"That is certainly good evidence," said Summerlee. "We can only accept his guidance and follow on to the westward."

We had proceeded some five more miles when again we saw a white arrow upon the rocks. It was at a point where the face of the cliff was for the first time split into a narrow cleft. Inside the cleft was a second guidance mark, which pointed right up it with the tip somewhat elevated, as if the spot indicated were above the level of the ground.

It was a solemn place, for the walls were so gigantic and the slit of blue sky so narrow and so obscured by a double fringe of verdure, that only a dim and shadowy light penetrated to the bottom. We had had no food for many hours, and were very weary with the stony and irregular journey, but our nerves were too strung to allow us to halt. We ordered the camp to be pitched, however, and, leaving the Indians to arrange it, we four, with the two half-breeds, proceeded up the narrow gorge.

It was not more than forty feet across at the mouth, but it rapidly closed until it ended in an acute angle, too straight and smooth for an ascent. Certainly it was not this which our pioneer had attempted to indicate. We made our way back--the whole gorge was not more than a quarter of a mile deep--and then suddenly the quick eyes of Lord John fell upon what we were seeking. High up above our heads, amid the dark shadows, there was one circle of deeper gloom. Surely it could only be the opening of a cave.
