"Whose judgment do you go by?" asked Rosie.
"By the guides'," replied Mr. George. "The guides know all about the mountain. They are up here every day. They have been watching it for years, and they can tell where it is safe to go, and where it is dangerous, better than any stranger. So I give up my judgment entirely, and go altogether by theirs. You will see Rollo and Josie coming back out of the smoke pretty soon, as safe as they went in."
This prediction proved to be true. In a few minutes, on account of some change in the gusts of wind, the masses of vapor in the crater broke into openings, and rolled off towards the other side, and in the openings Rosie could see the boys coming back over the black surface of the lava, their footsteps making a curious sound upon it, as if they were walking over clinkers. Very soon they reached the side, and then came toiling up the path which ascended the slope of sand.
Rollo and Josie were both full of enthusiasm in describing what they had seen at the bottom of the crater, and near the cone, and they strongly recommended to Rosie to go down too.
"I'll go with you, Rosie," said Josie, "and show you the way."
But Rosie declined the adventure, and Mr. George told her that she did right to do so.
"Why, what is there to be afraid of?" asked Josie. "There is no danger—not the least in the world."
"True," said Mr. George; "but going into such places does not give so much pleasure to young ladies as it does to such courageous young gentlemen as you. But I wish to go down myself, and I will leave Rosie under your care here while I am gone."
Pretty near where the party stood while engaged in this conversation, several persons were gathered about what seemed to be a fire. A sort of smoke came up from the ground in the centre of the group, and by the side of it were one or two baskets containing eggs, bread, bottles of wine, and other refreshments. Mr. George led the way to this place, and then he found that what seemed to be a fire was really a jet of hot steam and sulphurous gases that was issuing from a cleft among the rocks. The place was very near the crest of the crater, and the people that stood around it were watching to see men cook in the jets of steam. There was a little level place inside the crevice, just beneath the ground, where they could put eggs and other such things, and after leaving them there a short time, they were found to be nicely cooked. As fast as they were done, the men took them out and sold them to the bystanders.
Mr. George left Rosie and the two boys here while he went down into the crater. The guide went with him to show him the way. In about ten minutes Mr. George returned, and found the three children standing round the cuisine, as the men called the place where they cooked. Rollo had been buying some of the eggs, and he and Josie and Rosie were eating them.
