"Colin," said the professor, and his tone was so imperative that the boy turned sharply, "what is the matter? What are you watching?"

"I don't know, sir," said the boy; "I don't know much about fish, and I was waiting until it came nearer. I was going to say——"

He stopped suddenly.

"What?" asked the professor, a little impatiently.

"You'd laugh at me," the boy answered.

"You saw——"

"I saw a big green head with large eyes and spines on its back put its head out of the water," Colin said doggedly, "and it had a bright red mane. I couldn't think of anything but—but,"—he hesitated and then gulped out,—"a sea-serpent."

He half feared to look at his companion, feeling that a pitying smile would greet his news, but after a few seconds' silence, he glanced up and saw that his fellow-fisherman was looking grave and thoughtful. At that instant the boy felt a quick snap at his line and he struck, the salmon whirling away instantly. It was a good fight, and the fish was full of grit, sending a curious thrumming sensation up the line that set every

nerve aquiver. At last he got the fish stopped, and had just started to reel the big salmon in, when the apparition thrust its head out of the water not twenty feet from the boat. It distracted Colin's attention, and a few seconds later his line snapped.

"The salmon's got away," said Colin disgustedly.
