ADVENTURES OF CAPTAIN HORN
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.
