"Can't say.... Damn! ... If that infernal boat would only show up—"

He was lifting the whistle to sound a second summons when a rowboat rounded a projecting angle formed by the next warehouse down stream, and with clanking oar-locks swung in toward the landing. On her thwarts two figures, dipping and rising, labored with the sweeps. As they drew in, the man forward shipped his blades, and rising, scrambled to the bows in order to grasp an iron mooring-ring set in the wall. The other awkwardly took in his oars and, as the current swung the stern downstream, placed a hand palm downward upon the bottom step to hold the boat steady.

Calendar waddled to the brink of the stage, grunting with relief.

"The other man?" he asked brusquely. "Has he gone aboard? Or is this the first trip to-night?"

One of the watermen nodded assent to the latter question, adding gruffly: "Seen nawthin' of 'im, sir."

"Very good," said Calendar, as if he doubted whether it were very good or bad. "We'll wait a bit."

"Right-o!" agreed the waterman civilly.

Calendar turned back, his small eyes glimmering with satisfaction. Fumbling in one coat pocket he brought to light a cigar-case. "Have a smoke?" he suggested with a show of friendliness. "By Heaven, I was beginnin' to get worried!"

"As to what?" inquired Kirkwood pointedly, selecting a cigar.

He got no immediate reply, but felt Calendar's sharp eyes upon him while he manoeuvered with matches for a light.
