Canada or the
United States?"

"I think we ought to apply for help in both New York and Ontario," said
Mr. Baker, who was ordinarily a man of quiet demeanor, but now was worked
up to a state of nervous worry over the fate of his son.

"It's going to take some time to make trips to both sides of the river
and get the authorities of New York and Ontario busy," said Mr. Perry;
"but I suppose that's the only thing to do, and every minute wasted is an
opportunity lost. So let's go right away."

"Hold on, father," Cub interrupted; "you forget that we have a means of
calling help right here."

"It won't do to depend on your radio messages" his father replied. "You
know the experience Mr. Baker's son had trying to get help that way."

"Yes, but there were conditions that queered his calls," Cub replied.
"Just remember the results we got by calling our new friend, Max, at
Rockport, and what he did for us. Unless I'm badly mistaken, we can look
for more help from him."

"Yes, you're right, Bob," Mr. Perry admitted. "But I don't like the idea

"I bet I can have a police boat headed this way before you reach the
mainland."

"No, nothing doing," his father ruled unwaveringly. "You'd disappear just
the way the other boys did. We can't afford to run any more such risks."

"I'd be safe enough if you let me have that automatic o' yours, dad,"
Cub argued,

"No, sir-ree; I'm not going to leave you here alone to fight any gun
battle with a band of bandits."

But the boy was still undismayed by his father's resoluteness. He had one
more proposal to offer, and he presented it thus:

"You don't need to leave me here alone, dad. Mr. Baker may stay; you can
run the Catwhisker alone."

Both men had started toward the landing place, expecting the boy to
follow, but they stopped suddenly and faced about on hearing this new
proposition. Mr. Baker looked almost eagerly at Mr. Perry, it see
