"Wa-al, I 'lows ye'll stick ter thet," growled Old Rocks; "an' so I'll hev ter take yer erlong."

"An' Oi'm wid him, begobs!"

But the guide would not agree to that.

"Somebody's got ter go back ter camp an' look out fer things," he said.

"I reckons you an' ther professor is ther ones."

Barney groaned.

"Profissor, can't yez go alone?" he asked. "It's nivver a chance have Oi had ter take a hand in a bit av a ruction loately, av ye will except th'

chance Oi had th' doay."

But Professor Scotch had no fancy to return through the darkness to the camp, and he insisted that Barney should accompany him. The Irish boy was forced to succ.u.mb, and he parted from Frank with the utmost reluctance and regret.

"We have fought an' bled togither," he said, "an' it's harrud to be parruted loike this."

In a short time Barney and the professor were returning to the camp, while, with Frank Merriwell at his heels, Old Rocks again took up the trail.

Frank marveled at the swiftness with which Old Rocks swung over the ground.

Through the timber they made their way, and then through a narrow ravine, and four or five miles had been covered before the guide paused to speak.

"They're makin' straight fer ther lake," he said. "I don't like that."

"Why not?"

"Ef ther p'izen varmints has canoes--wa-al, we won't be liable ter foller 'em farther than ther lake."

"That is true. We will hope they have no canoes."

Onward they went once more, Old Rocks having lighted a fresh torch, which left but one remaining.

The night was on the wane. Already the sounds of the middle night were hushed. The owls had stopped their hooting, and now, on noiseless wing, were making their last hunting rounds before day should come.

Afar on the side of a mountain a wolf was howling like a dog baying to the moon. The stars which filled the sky seemed to prophesy of dawn.

Bending low, now and then swinging his torch to fan it into a stronger flame, Old Rocks almost raced along the trail, while the boy at his heels kept close.

They were like two tongueless hounds upon a hot scent.

And thus they came, at last, to the lake.

Not a word did Old Rocks say for several minutes, but he moved up and down the sh.o.r.e, reading the "sign," while his companion waited with the greatest anxiety.

At length, with a grated exclamation of rage and dismay, the man flung himself on the ground.

"It's jest as I feared," he growled. "Ther onery varmints hed canoes hid hyar, an' we kin trail 'em no farther."

"Then what can we do?" fluttered the discomfited boy.

"Northin' but wait fer daylight."

Now on the still air very faintly was heard a distant tone of music; a sweet whistle, at first low, rising and falling, and then gradually becoming more distinct. It came nearer and nearer till it seemed to fill the air all about, and then, looking upward, they saw dark forms flitting between them and the stars.

The wild ducks were flying.

The musical note pa.s.sed on, receded, grew fainter and fainter, till, at last, it died out in the distance.

From the lake came a far-off trumpet call, and then another--the mellow note of the wild geese.

The world was awakening; the day was near.

The stars were growing paler now. In the eastern sky was a bit of gray, which slowly broadened, pushing upward and blotting out the stars.

Where all before was dark, the morning twilight began to show the black forms of things.

The outlines of tree trunks could be seen, and they seemed to stand like ghosts, reaching out shadowy arms, as if feeling their way through the dimness.

The birds which through the long night had slept in the low bushes were beginning to chirp and flutter.

All at once, Old Rocks started and clutched Frank's arm.

"Listen!" he whispered.

The sound of footsteps told them some one was approaching.

"Back!" whispered the guide, leading the way. "We must see who ther critter is, an' he musn't see us."

Hastily they drew into the deep shadows, holding their rifles ready for use in case they should need them.

Nearer and nearer came the footsteps, and then the dark figure of a man appeared, advancing through the dusky darkness.

The man was alone, and he halted on the sh.o.r.e of the lake, within a short distance of the crouching man and boy. They saw him bow his head on his breast and stand there in silence.

Several minutes pa.s.sed. At last, the unknown lifted his head, stretched out his arms, and uttered a long, mournful cry that seemed to come from a breaking heart.

Old Rocks rose and glided swiftly and silently toward the stranger, who did not hear him approach. The guide's hand dropped on the man's shoulder, and he said:

"h.e.l.lo, Hermit. Whatever be yer doin' hyar?"

The strange man turned, and Frank saw that it was indeed the Hermit of the Yellowstone.

"Doing?" he said, hoa.r.s.ely. "I am seeking rest--seeking rest! I'll never find it till I rest in the grave!"

"You must hev a derned bad liver, or somethin' o' ther sort," sneered Old Rocks. "I don't understand a critter like you none whatever."

"I do not expect you to understand me. You do not know my story. If I were to tell you----"
