CHAPTER XXVII.
THE MAN-WOLF'S STORY.
An accident to the dynamo in that place where there was no fuel, and electricity must be depended upon for light and heat, was so serious a matter that, for a moment, even Cabot's curiosity concerning his host was merged in anxiety.
"Where shall I find it ?" he asked.
"In the cavern back of this room.

The doorway is behind that bearskin.
This upper row of keys connects with the storage battery, and the second key controls the lights of the dynamo room.

If there is a bad break I can manage to get to it, but I wouldn't try until you came, because I promised not to move." All this was said in a voice that faltered from weakness, and a wave of pity surged in Cabot's breast as he realised how dependent upon him this man, so recently a mental as well as a physical giant, had become.
"I expect I shall be able to attend to it all right," he said decisively, as he turned on the stored current that would light the unknown cavern.

"At any rate, I shall be able to report the condition of things, so that you can advise me what to do, or else my training is a greater failure than I think." With this he lifted the bearskin, opened a door thus disclosed, and found himself in a small, well-lighted cavern that was at once a dynamo room, a workshop, and a storehouse for a confused miscellany of articles.

Without pausing to investigate any of these he went directly to a dynamo that had been set up at one side and examined it carefully.
It appeared in perfect order, and the trouble must evidently be sought elsewhere.
Cabot had wondered by what power the dynamo was driven, and now, hearing a sound of running water, he stepped in that direction.
