g? Wait a bit, and you'll see. Why, I shall begin to make a regular
map plan of that place below. It will take months and months perhaps,
but we shall explore a bit at a time, and mark the roads and drifts with
arrows, and we shall all get more and more used to it."

"One could hardly get used to such a place as a tin mine, Sam," said
Gwyn.

"Oh, yes, we could, sir, and we shall. But I see you didn't make the
use of your eyes that I did, or you'd have more to say."

"What do you mean?" cried Gwyn.

"Didn't you see how rough all the mining had been?"

"Well, yes."

"And don't you see what that means?"

"No."

"Then I'll tell you, both of you--there's ore there enough to make your
fathers the richest gentlemen in these parts; and there isn't a company
in Cornwall as wouldn't do anything to get it. New-fashioned machinery
will do what the old miners couldn't manage, and we won't have any more
losing our way. There, I'm busy; so good-bye, and good luck to you
both. Some day, when you grow to be men, you'll thank me for what I've
done, for I've about made you both."

it doesn't matter. Come on, and let's give old Grip a jolly good run.
Come on, old dog."

Grip did not come, but led off; and they made for the edge of the cliff,
which ran along, on an average, three hundred feet above where the waves
beat at their feet, but they had not gone far before Joe, who had
glanced back, said quickly,--

"What's Tom Dinass following us for out here?"

Gwyn glanced back, too.

"Not following us," he said quickly; "he's making for the bend of the
rock yonder."

"Yes," said Joe; "but that's where he knows we shall have to pass. What
does he mean? He must have seen us at the mine and followed."

"I don't know," said Gwyn, thoughtfully; and a peculiar feeling of
uneasiness attacked him. "But never mind; let's go on, or he'll think
we're afraid of him."

"I am," said Joe, frankly.

"Well, then, if you are, you mustn't show it. Come on. Quiet, Grip."

For though the man was several hundred yards away, Grip had caught sight
of him, set up all the thick hair about his neck, and uttered a low,
deep growl.

CHAPTER THIRTY SEVEN.

GWYN'S ERROR.

All at once, as the boys went along near the cliff edge, they found that
Dinass had disappeared, and Joe expressed himself as being relieved.

"Went back beyond that ridge of rocks, I supp
