The building nearest the fort was selected as their future abode, and never did mansion receive a more thorough scouring. Walter plied the brush, while the captain dashed the water about, and Chris wiped the floor dry with armfuls of Spanish moss. Charley, on account of his still lame shoulder, was excused from this labor.

Leaving his companions thus busily employed, Charley took his way to the building that had aroused his curiosity in the morning, the one in which they had found no skeletons.

This building was a trifle larger than its fellows and differed very little from them in external appearance, except that from its roof projected a little tower. It was the inside, however, which had excited our young hunter's curiosity. At one end was a kind of raised platform and the space between it and the entrance was filled with benches of stone. Charley reverently removed his hat ad he entered, for he had guessed the character of the place during his morning visit. It was a chapel that the hardy adventurers of long ago had erected for the worship of their Maker.

Upon the stone altar stood several vessels, likely of gold or other precious metal for they were apparently untouched by the ravages of time. Charley gave them hardly a glance but passed on to the end of the building until he stood beneath the tiny tower.

One glance upwards, and he uttered an exclamation of satisfaction. Directly above his head in the little tower hung a large ship's bell. A part of the mystery of the tolling was solved, but the most puzzling part remained.

Charley sat down on one of the stone benches and fell into a deep study. There was the bell but where was the mysterious ringer? The bell rope had long ago rotted away. The walls had once been plastered and were still too smooth to offer a foothold to the most expert climber. How then to account for the regular nightly tolling? The mystery had in reality deepened instead of lightened.

When Charley at last left the building, he was still puzzled in mind and had decided to say nothing about his discovery to his companions. Chris and the captain would be sure to view the matter in its most supernatural light.

On his return, he found the house scrubbed sweet and clean and the workers taking a rest after their labors. Feeling that he had not performed his just share of the work of the day, Charley took upon himself the carrying in and arranging of their possessions. With these unpacked and arranged, the room looked less bare and much more cozy and home-like.

But Charley viewed their scanty possessions with a trace of dissatisfaction. Two rifles, two shotguns, a half of their ammunition, and a half of their scanty stock of provisions had been lost when the canoe upset. Of their original outfit, the two boys retained only their pistols and ammunition and the tattered clothes they were wearing. The captain and Chris still had their four guns but their clothing was as rent and tattered as the two boys'. Of the provisions there only remained a little sugar, a few pounds of flour, and a small strip of bacon.

"I tell you what it is," said Charley, as he joined his companion outside, "we have got to do some tall hustling the next two days. We have got to lay in a stock of food sufficient to last us for at least a week, and we have got to make some kind of windows and doors for that building, besides, which, we have got to manufacture some kind of clothing for ourselves—mine are almost dropping from me."
