"Coast Pilot," and Bowditch's "Navigator" were all the weapons Disko needed to guide him, except the deep-sea lead that was his spare eye. Harvey nearly slew Penn with it when Tom Platt taught him first how to "fly the blue pigeon"; and, though his strength was not equal to continuous sounding in any sort of a sea, for calm weather with a seven-pound lead on shoal water Disko used him freely. As Dan said:
"'Tain't soundin's dad wants. It's samples. Grease her up good, Harve." Harvey would tallow the cup at the end, and carefully bring the sand, shell, sludge, or whatever it might be, to Disko, who fingered and smelt it and gave judgment As has been said, when Disko thought of cod he thought as a cod; and by some long-tested mixture of instinct and experience, moved the We're Here from berth to berth, always with the fish, as a blindfolded chess-player moves on the unseen board.

But the fog would not lift, and the fish were biting, and no one can stay helplessly afraid for six hours at a time. Harvey devoted himself to his lines and the gaff or gob-stick as Tom Platt called for them; and they rowed back to the schooner guided by the bell and Tom's instinct; Manuel's conch sounding thin and faint beside them.

A few days later he was out with Manuel on what should have been forty-fathom bottom, but the whole lengt
