"He has many other contrivances," Captain Bellwood went on. "He has explained that, by means of electricity, he can make his canoe or himself glow with a white light in the darkest night."

"Begorra! we've seen him glow!" shouted Barney.

"And he also states that he has wires connecting various batteries in yonder hut, so that he can frighten away superstitious hunters who otherwise might take possession of the hut and give him trouble."

"Whoop!" shouted Barney. "Thot ixplains th' foire-allarum an' th' power thot throwed me inther th' middle av th' flure! Oi nivver hearrud th' bate av it!"

"It is wonderful, wonderful!" gasped Professor Scotch.

At this moment, a series of wild shrieks came from the hut, startling them all.

"It is Gage," said Frank. "He seems to be badly frightened."

They hurried toward the hut, Frank leading. Gage was still on the couch, and he shrieked still louder when he saw Frank; an expression of the greatest terror coming to his face.

"Take him away! Take him away!" screamed the wretched fellow. "He is dead! I killed him! Don't let him touch me!"

Then he began to rave incoherently, sometimes frothing at the mouth.
