When Fred pointed out the spot his companions were at once
interested and suggested that he should stop at the dock, which
almost seemed to invite their coming.

"There's Susie Stevens now," called John, pointing as he spoke to
a nearby canoe in which two young girls were seated. One of them
was paddling, while her companion was seated in the opposite end
of the frail little craft.

At the moment of John's discovery apparently Miss Susie also
became aware of the approach of the Black Growler. As she lifted
her paddle to salute the Go Ahead boys, her companion, who
doubtless was unfamiliar with canoes, reached forward to pick up
a sweater to wave at the motor-boat; she suddenly destroyed the
balance of the little canoe. Instantly it was overturned and both
girls were thrown into the St. Lawrence.


CHAPTER XVI

THE RESCUE

A cry of horror and alarm arose from the startled boys when they
beheld the accident. In a moment one of the girls was seen
swimming near the overturned canoe. The other, however, was not
within sight.

"It's time for us to do something!" shouted John, who was almost
beside himself in his excitement.
