"Do you hear that noise?" he asked.
"Of course I hear it," the boy answered; "that's what woke me up. But what is it?" he continued, as the roar swelled upon the wind.
"What does it sound like?" the gunner asked him.
The boy listened carefully for a minute or two and then shook his head.
"Hard to say," he answered. "It sounds like a cross between Niagara and a circus."
Scotty, who had overheard this, looked round.
"That's not bad," he said; "that's just about what it does sound like."
"But what is the cause of it, Hank?" the boy queried again. "I never heard such a row!"
"Fur seals!" was the brief reply.
