Madden hurried to his cabin and returned with binoculars. The men foregathered curiously about him as he scanned the vessel. He ran his eyes over the tub from stem to poop. She stood out with absolute distinctness in the glaring light. He could see her high prow, the swinging buffers along her side, the wide-mouthed ventilators. He could even make out her name in rusty letters under the wheel-house. Her small boats were in place, but he saw neither life nor movement aboard. She appeared as deserted as a pile of scrap iron.

"W'ot are they doin'?" queried Galton.

"Nothing." Madden was puzzled over the strange condition of the tug.

"Ain't they crowdin' to th' side, sir, lookin' at us and fixin' to come to us?"

"Nobody's on her," replied Madden. "At least I don't see anyone."

"W'ot! W'ot! Nobody on 'er! Is she deserted, too? Just like the Minnie B!" chorused apprehensive voices.

"Seems so," frowned Madden, then he made up his mind quickly and moved over to the small boat which had been hauled up on the forward pontoon.

"Fall to, men, lower that dinghy. We'll go over and see what's the trouble."

The crew went about their task with a sudden slump of enthusiasm.

"If the crew's gone, sir," mumbled one of the men, as he paid out the rope, "w'ot's the use goin' across?"
