"This wye, sir."

At his guide's heels Kirkwood threaded the crowd and, entering the tenement, stumbled through a gloomy and unsavory passage, to come out at last upon a scanty, unrailed veranda overlooking the river. Ten feet below, perhaps, foul waters purred and eddied round the piles supporting the rear of the building. On one hand a ladder-like flight of rickety steps descended to a floating stage to which a heavy rowboat lay moored. In the latter a second waterman was seated bailing out bilge with a rusty can.

"'Ere we are, sir," said the cabman's nephew, pausing at the head of the steps. "Now, where's it to be?"

The American explained tersely that he had a message to deliver a friend, who had shipped aboard a vessel known as the Alethea, scheduled to sail at floodtide; further than which deponent averred naught.

The waterman scratched his head. "A 'ard job, sir; not knowin' wot kind of a boat she are mykes it 'arder." He waited hopefully.

"Ten shillings," volunteered Kirkwood promptly; "ten shillings if you get me aboard her before she weighs anchor; fifteen if I keep you out more than an hour, and still you put me aboard. After that we'll make other terms."

The man promptly turned his back to hail his mate. "'Arf a quid, Bob, if we puts this gent aboard a wessel name o' Allytheer afore she syles at turn o' tide."

In the boat the man with the bailing can turned up an impassive countenance. "Coom down," he clenched the bargain; and set about shipping the sweeps.

Kirkwood crept down the shaky ladder and deposited himself in the stern of the boat; the younger boatman settled himself on the midship thwart.

"Ready?"
