Herc landed with a crash on something soft and yielding. For an instant or two he actually found himself wondering if he had been killed, but as soon as his rudely jolted senses reasserted themselves he found that, thanks to the soft substance he had landed upon, he was not even sprained.

"Well, here's a nice kettle of fish!" exclaimed Herc to himself, rubbing his head ruefully. "I'm a whole lot worse off now than I was before."

He sat up and tried to collect his thoughts. A moment's reflection placed him pretty well in possession of the facts as they were. He had been dashing at top speed down the dark passage when he suddenly found himself precipitated into space. There had been no trap-door or opening in the passage when he came down it before, of that he was certain; therefore it was plain that some sort of device must have been operated to open a pitfall under his feet and prevent his escape.

"The question now is, though, where am I?" mused Herc.

All about him was velvety blackness, so dark that it could almost be felt. The air was filled with an odd kind of musty odor, a damp reek as of some place infested with fungus growth and unclean things.

"Some sort of a cellar," thought the lad, "and it's not likely there's any way out of it but the way I came. There might be a ladder there, of course, but I didn't notice it as I came down. Ouch! what a bump! I'm lucky it didn't break every bone in my body."

Herc felt in his pockets for his matchbox. Having found it, he struck a lucifer. By its light he made a brief but comprehensive survey of his surroundings.

He had fallen on a rotting pile of what appeared to be old sails, or canvas from which sails were made. From this he judged that the structure above him must have been at some time occupied by sail-makers, and that this cellar had formed a sort of rubbish heap for the refuse of the place.

For the rest, the lighting of another match showed him that the cellar was about eighty feet square and evidently extended under the whole of the house above. There was no means of egress, and he could not even see the trap-door above him through which he had made such a hasty entrance into the place.

The walls were smooth, and made of some sort of cement. There was no hope of scaling them, even had there been anything to gain by such a proceeding. So far as he could see, Herc was in as effectual a trap as it would have been possible to devise. Only a ladder could do him any good, and so far as obtaining that was concerned, he felt that he might just as well wish for anything impossible of attainment.
