He had been hoping it might be possible for him to catch more fish than did his companion, and he gave all his attention to the line once more, until he noted the fact that an expression of anxiety had come over the keeper's face.

"Is anything gone wrong, sir?" he asked with mild curiosity.

"I wish I knew, Sonny, an' that's a fact. I can't make out why a side-wheel steamer should be comin' so near the ledge, an' then agin, why don't she shift her course? It ain't as if they couldn't hear the whistle."

Even then Sidney failed to understand that they might be in any danger, until Captain Eph began shouting at the full strength of his lungs as he hauled up the anchor hurriedly, and again the lad asked:

"Is there any danger, sir?"

"I can't make out why the idjuts don't shift their course! Unless they take a turn at the wheel mighty soon, they'll not only run us down, but stand a precious good show of pilin' up high an' dry on Carys' Ledge! Sing out, Sonny, an' make all the noise you can!"

Sidney obeyed instantly, for now the churning noise sounded so near at hand that he almost began to believe he could distinguish the bow of the steamer amid the thick gray mist, and both he and Captain Eph screamed at the full force of their lungs, the keeper shouting now and then:

"Port! Port your hel'um, or you'll be on the ledge!"

Nearer and nearer the noise came until it seemed as if the stranger was directly upon them, and Captain Eph had thrown off his coat and boots ready for the worst, when there was an answering toot from the steam whistle.

"Port! Port, you lubbers! You're close afoul of Carys' Ledge!"
