"And father--my father is with him in the canoe!" screamed Elsie Bellwood, in delight.

It was true. The white canoe was approaching, still gliding noiselessly over the water, without any apparent power of propulsion, and in it were seated two men. One had a long white beard and a profusion of white hair. He was dressed entirely in white, and sat in the stern of the canoe. The other was Captain Justin Bellwood, quite unharmed, and looking very much at his ease.

The little party flocked to the sh.o.r.e to greet the captain, who waved his hand and called rea.s.suringly to Elsie. As soon as the canoe touched and came to a rest, he stepped out and clasped his daughter in his arms, saying, fervently:

"Heaven be thanked! we have come through many dangers, and we are free at last! Neither of us has been harmed, and we will soon be out of this fearful swamp."

The man with the white hair and beard stepped ash.o.r.e and stood regarding the girl intently, paying no heed to the others. Captain Bellwood turned to him, saying:

"William, this is my daughter, of whom I told you. Elsie, this is your Uncle William, who disappeared many years ago, and has never been heard from since till he set me free to-day, after I was abandoned by those wretches who dragged us here."

"My uncle?" cried the girl, wonderingly. "How can that be? You said Uncle William was dead."

"And so I believed, but he still lives. Professor Scotch, I think we had the pleasure of meeting in Fardale. Permit me to introduce you to William Bellwood, one of the most celebrated electricians living to-day."

As he said this, Captain Bellwood made a swift motion which his brother did not see. He touched his forehead, and the signal signified that William Bellwood was not right in his mind. This the professor saw was true when he shook hands with the man, for there was the light of madness in the eyes of the hermit.

"My brother," continued Captain Bellwood, "has explained that he came here to these wilds to continue his study of electricity alone and undisturbed. He took means to keep other people from bothering him. This canoe, which contains a lower compartment and a hidden propeller, driven by electricity, was his invention. He has arrangements whereby he can use a powerful search-light at night, and----"

"That search-light came near being the death of me," said Frank. "He turned it on me last night just in time to show me to my enemy."

"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 superst.i.tious 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.

"He is mad!" cried Professor Scotch.

"It is retribution!" came solemnly from Frank's lips.

Two days later a party of eight persons emerged from the wilds of the great Dismal Swamp and reached a small settlement. They were Frank Merriwell, Barney Mulloy, Professor Scotch, Leslie Gage, Captain Bellwood and his brother William, Socato the Seminole, and last, but far from least, Elsie Bellwood.

"What shall be done with Gage?" asked Professor Scotch.

"He shall be given shelter and medical treatment," declared Frank; "and I will see that all the bills are paid."

"Thot's the only thing Oi have against ye, me b'y. Ye wur always letting up on yer inemies at Fardale, an' ye shtill kape on doin' av it."

"If I continue to do so, I shall have nothing to trouble my conscience."

Frank did take care of Gage and see that he was given the best medical aid that money could procure, and, as a result, the fellow was saved from a madhouse, for he finally recovered. He seemed to appreciate the mercy shown him by his enemy, for he wrote a letter to Frank that was filled with entreaties for forgiveness and promised to try to lead a different life in the future.

"That," said Frank, "is my reward for being merciful to an enemy."

If Jack Jaggers did not perish in the Everglades, he disappeared. Ben Bowsprit and Black Tom also vanished, and it is possible that they left their bones in the great Dismal Swamp.

William Bellwood, so long a hermit in the wilds of Florida, seemed glad to leave that region.

CHAPTER x.x.xVIII.

IN THE MOUNTAINS AGAIN.

Leaving their friends in Florida, Frank, Barney and the professor next moved northward toward Tennessee, Frank wishing to see some of the battlegrounds of the Civil War.

The boys planned a brief tour afoot and were soon on their way among the Great Smoky Mountains.

Professor Scotch had no heart for a "tour afoot" through the mountains, and so he had stopped at Knoxville, where the boys were to join him again in two or three weeks, by the end of which period he was quite sure they would have enough of tramping.

Frank and Barney were making the journey from Gibson's Gap to Cranston's Cove, which was said to be a distance of twelve miles, but they were willing to admit that those mountain miles were most disgustingly long.

They had paused to rest, midway in the afternoon, where the road curved around a spur of the mountain. Below them opened a vista of valleys and "coves," hemmed in by wild, turbulent-appearing ma.s.ses of mountains, some of which were barren and bleak, seamed with black chasms, above which threateningly hung grimly beetling crags, and some of which were robed in dense wildernesses of pine, veiling their faces, keeping them thus forever a changeless mystery.

From their eyrie position it seemed that they could toss a pebble into Lost Creek, which wound through the valley below, meandered for miles amid the ranges, tunneling an unknown channel beneath the rock-ribbed mountains, and came out again--where?

Both boys had been silent and awe-stricken, gazing wonderingly on the impressive scene and thinking of their adventures in New Orleans and in Florida, when a faint cry seemed to float upward from the depths of the valley.

"Help!"

They listened, and some moments pa.s.sed in silence, save for the peeping cry of a bird in a thicket near at hand.

"Begorra! Oi belave it wur imagination, Frankie," said the Irish lad, at last.

"I do not think so," declared Frank, with a shake of his head. "It was a human voice, and if we were to shout it might be---- There it is again!"

There could be no doubt this time, for they both heard the cry distinctly.

"It comes from below," said Frank, quickly.
