"He'll be all right some day," said George seriously. "You see if he
won't."

"I'm glad you're the trainer and not I, anyway," said John grimly.

Laughing and joking, bantering one another and full of spirits they soon
came to their destination, and prepared to measure off the distances
according to the code.

"Read what the code says first of all, Grant," exclaimed Fred. "That'll
help us all to know just what we are to do."

"You ought to know it by heart now I should think," laughed Grant.
"Still, I'll read it if you say so."

"Go ahead, Grant," urged John, and once more they listened to the words
that meant so much to every one of them.

"Take a course due north one hundred feet from the southern extremity of
shark rock, then east fifty feet and north by east thirty-three. Dig."

"Dig," cried George. "That's the important word. Dig! Dig! Dig!"

"Wait a minute, Pop," exclaimed Grant. "We've got to find the place
where we are to dig first, you know."

"All right," said George eagerly. "Here's the compass."

"Lay it flat out on the rock," directed Grant. "We'll take our first
observation."

The little instrument was placed on top of the great rock while the five
gold seekers crowded around it eagerly. The delicate indicator fluttered
excitedly for some moments, then its fluctuations gradually became less
and less. At last it stopped entirely, the tiny needle pointing exactly
north.

"There we are," exclaimed George. "Now if we go directly opposite to the
way that needle is pointing we'll find the southern extremity of this
rock."

"That's what we want," cried Grant. "You walk down there, Fred."

Fred hastened to obey and soon stationed himself at the opposite end of
the rock, which happened to be the tail of the shark.

"Get in direct line now," directed Grant.

"You'll have to tell me what that is," replied Fred. "I can't tell the
exact spot, you know, from looking at it."

"That's right," agreed John, "and we don't want to make any mistake at
the very beginning of our calculations. That would throw us 'way off
later on."

"Take this stick," suggested George, bringing up a long thin shoot he
had torn from one of the nearby bushes. "Lay it flat out on the rock and
in a direct line with the needle. Be sure to get it exact and if we do
we can easily enough find the 'southern extremity.'"

This was quickly done, and in a few moments the exact spot desired was
located beyond the shadow of a do
