"Come along, girls. The guides can take us farther," said Miss Morley. "Don't be frightened, for it's perfectly safe, and they won't let us go into any danger."

So they went some way along the mountain and turned down a side path towards the crater. It was difficult walking, for they were all among lava and sliding cinders, but the guides kept close by them, and helped them over difficult places. When they had descended perhaps a hundred feet or so, the ground became percolated with steam, jets of it poured from holes among the rocks, and the cinders upon which they stood felt warm to their boots. The guides brought the party to a halt upon a ledge of volcanic rock, from below which ran a sheer slide of hot cinders into the ravine. From here there was a splendid near view of the cone, its top yellow with sulphur, and at its base a lake of molten lava. One of the guides, a venturesome fellow, climbed down by another path and fetched lumps of sulphur as souvenirs for the girls, and the other guide pressed upon them pieces of lava into which, while hot, he had inserted coins, so that they had set into the mass when cool. They were naturally immensely delighted with these mementoes, and put them in their pockets, quite unsuspecting of the sequel that was to ensue.

It was a fearful scramble back up the steep path over the sliding cinders. The guides held out a stick or a hand to help at awkward corners, and being young and active the party managed to scale the side of the ravine and regain the summit of the mountain without any accidents, though Delia confessed afterwards that she had fully expected to tumble backwards and roll into the lava, a fear which Miss Morley pooh-poohed entirely.

"There was no danger unless you fainted, and the guides were close at your elbow the whole time," she declared.

The smiling officials in the gray uniforms and red-banded caps had indeed seemed the good geniuses of the excursion, but alack! they exhibited a different aspect when they had conducted their party back to the entrance of the funicular railway. Not satisfied with the payment which the government tariff allowed them to charge, they demanded from each of the visitors exorbitant tips in consideration of the little lumps of sulphur and lava which they had given them from the crater. The girls, who had supposed these to be presents, were most indignant.

"Five francs for a scrap of sulphur!"

"And we'd just called him such a kind man!"

"Let him keep his wretched souvenirs!"

"No, no! I want mine!"

"It's too bad!"
