the face of the rocks took fire. Ralph watched with interest the dry leaves blaze and the green ones splutter, and then he thought it would be a pity to scorch those vines, which were among the few green things about them, and he tried to put out the fire. But this he could not do, and, when he called Maka, the negro was not able to help him. The fire had worked its way back of the green vines, and seemed to have found good fuel, for it was soon crackling away at a great rate, attracting the rest of the party.
“Can’t we put it out?” cried Miss Markham. “It is a pity to ruin those beautiful vines.”
The captain smiled and shook his head. “We cannot waste our valuable water on that conflagration,” said he. “There is probably a great mass of dead vines behind the green outside. How it crackles and roars! That dead stuff must be several feet thick. All we can do is to let it burn. It cannot hurt us. It cannot reach your tent, for there are no vines over there.”
The fire continued to roar and blaze, and to leap up the face of the rock.
“It is wonderful,” said Mrs. Cliff, “to think how those vines must have been growing and dying, and new ones growing and dying, year after year, nobody knows how many ages.”
“What is most wonderful to me,” said the captain, “is that the vines ever grew there at all, or that these bushes should be here. Nothing can grow in this region, unless it is watered by a stream from the mountains, and there is no stream here.”
Miss Markham was about to offer a supposition to the effect that perhaps the precipitous wall of rock which surrounded the little plateau, and shielded it from the eastern sun, might have had a good effect upon the vegetation, when suddenly Ralph, who had a ship’s biscuit on the end of a sharp stick, and was toasting it in the embers of a portion of the burnt vines, sprang back with a shout.
“Look out!” he cried. “The whole thing’s coming down!” And, sure enough, in a moment a large portion of the vines, which had been clinging to the rock, fell upon the ground in a burning mass. A cloud of smoke and dust arose, and when it had cleared away the captain and his party saw upon the perpendicular side of the rock, which was now revealed to them as if a veil had been torn away from in front of it, an enormous face cut out of the solid stone.
CHAPTER III. A CHANGE OF LODGINGS
The great face stared down upon the little party gathered beneath it. Its chin was about eight feet above the ground, and its stony countenance extended at least that distance up the cliff. Its features were in low relief, but clear and distinct, and a smoke-blackened patch beneath one of its eyes gave it a sinister appearance. From its wide-stretching mouth a bit of half-burnt vine hung, trembling in the heated air, and this element of motion produced the impression on several of the party that the creature was about to open its lips.
Mrs. Cliff gave a little scream, — she could not help it, — and Maka sank down on his knees, his back to the rock, and covered his face with his hands. Ralph was the first to speak.
“There have been heathen around here,” he said. “That’s a regular idol.”
“You are right,” said the captain. “That is a bit of old-time work. That face was cut by the original natives.”
The two ladies were so interested, and even excited, that they seized each other by the hands. Here before their faces was a piece of sculpture doubtless done by the people of ancient Peru, that people who were discovered by Pizarro; and this great idol, or whatever it was, had perhaps never before been seen by civilized eyes. It was wonderful, and in the conjecture and exclamation of the next half-hour everything else was forgotten, even the three sailors.
Because the captain was the captain, it was natural that every one should look to him for some suggestion as to why this great stone face should have been carved here on this lonely and desolate rock. But he shook his head.
“I have no ideas about it,” he said, “except that it must have been some sort of a landmark. It looks out toward the sea, and perhaps the ancient inhabitants put it there so that people in ships, coming near enough to the coast, should know where they were. Perhaps it was intended to act as a lighthouse to warn seamen off a dangerous coast. But I must say that I do not see how it could do that, for they would have had to come pretty close to the shore to see it, unless they had better glasses than we have.”
The sun was now near the horizon, and Maka was lifted to his feet by the captain, and ordered to stop groaning in African, and go to work to get supper on the glowing embers of the vines. He obeyed, of course, but never did he turn his face upward to that gaunt countenance, which grinned and winked and frowned whenever a bit of twig blazed up, or the coals were stirred by the trembling negro.
After supper and until the light had nearly faded from the western sky, the two ladies sat and watched that vast face upon the rocks, its features growing more and more solemn as the light decreased.
“I wish I had a long-handled broom,” said Mrs. Cliff, “for if the dust and smoke and ashes of burnt leaves were brushed from off its nose and eyebrows, I believe it would have a rather gracious expression.”
As for the captain, he went walking about on the outlying portion of the plateau, listening and watching. But it was not stone faces he was thinking of. That night he did not sleep at all, but sat until day-break, with a loaded gun across his knees, and another one lying on the ground beside him.
When Miss Markham emerged from the rude tent the next morning, and came out into the bright light of day, the first thing she saw was her brother Ralph, who looked as if he had been sweeping a chimney or cleaning out an ash-hole.
“What on earth has happened to you!” she cried. “How did you get yourself so covered with dirt and ashes?”
“I got up ever so long ago,” he replied, “and as the captain is asleep over there, and there was nobody to talk to, I thought I would go and try to find the back of his head” — pointing to the stone face above them. “But he hasn’t any. He is a sham.”
“What do you mean?” asked his sister.
“You see, Edna,” said the boy, “I thought I would try if I could find any more faces, and so I got a bit of stone, and scratched away some of the burnt vines that had not fallen, and there I found an open place in the rock on this side of the face. Step this way, and you can see it. It’s like a narrow doorway. I went and looked into it, and saw that it led back of the big face, and I went in to see what was there.”
“You should never have done that, Ralph,” cried his sister. “There might have been snakes in that place, or precipices, or nobody knows what. What could you expect to see in the dark?”
“It wasn’t so dark as you might think,” said he. “After my eyes got used to the place I could see very well. But there was nothing to see — just walls on each side. There was more of the passageway ahead of me, but I began to think of snakes myself, and as I did not have a club or anything to kill them with, I concluded I wouldn’t go any farther. It isn’t so very dirty in there. Most of this I got on myself scraping down the burnt vines. Here comes the captain. He doesn’t generally oversleep himself like this. If he will go with me, we will explore that crack.”
When Captain Horn heard of the passage into the rock, he was much more interested than Ralph had expected him to be, and, without loss of time, he lighted a lantern and, with the boy behind him, set out to investigate it. But before entering the cleft, the captain stationed Maka at a place where he could view all the approaches to the plateau, and told him if he saw any snakes or other dangerous things approaching, to run to the opening and call him. Now, snakes were among the few things that Maka was not afraid of, and so long as he thought these were the enemies to be watched, he would make a most efficient sentinel.
When Captain Horn had cautiously advanced a couple of yards into the interior of the rock, he stopped, raised his lantern, and looked about him. The passage was about two feet wide, the floor somewhat lower than the ground outside, and the roof but a few feet above his head. It was plainly the work of man, and not a natural crevice in the rocks. Then the captain put the lantern behind
