Barely more than a topsail could be made out, even through the marine glass of the young watch officer.

"Hold the light on her; we'll overtake and examine her, anyway," was Ensign Hastings's quick decision. From the bridge he gave orders for the engine room to go ahead with increased speed. While the gunboat was bounding off after the stranger, time came to call the port watch. Eph Somers came up to the bridge, somewhat sleepy.

"Same old story, I guess," yawned Eph. "Have you passed the word to the executive office?"

"Not yet," Hal replied. "I didn't believe it worth while to break the slumber of Mr. Fullerton, or of the commander, until we got close to see whether the stranger looks in the least like the 'Juanita.'"

"I don't believe the 'Juanita' is anywhere on this wide ocean," muttered
Eph, stifling a yawn.

"It doesn't look that way," smiled Hastings.

Down before the wheelhouse a bell began to sound briskly.

"Eight bells; your watch, Mr. Somers," announced Hastings. "But I am going to remain on the bridge with you for a while. I want a look at that mud-hooker over yonder."

Within fifteen minutes more the gunboat was running fairly close, though off to starboard.

"That doesn't look even a little bit like the 'Juanita,'" muttered
Ensign Eph, disgustedly. "Why, she's longer than the Cobtown schooner.
Besides, the 'Juanita' is a two-sticker, while that hooker yonder has
a third mast with a yawl-rig leg-o'-mutton sail."
