this, Gregory reflected. But then the whole business was a long chance. And Lang knew his business.

Imbued with a fisherman's sixth sense of feeling his way along familiar channels rendered unfamiliar by fog, Bill Lang piloted his craft skilfully down the silent bay in the direction of the open sea.

Crouching in the bow, Mexican Joe sought with cat-like eyes to pierce the gray veil of blinding fog. Narrowly averting collision with unlighted harbor-boats, bumping at times over sandy shoals, plowing through grass-grown mud-flats and skirting dangerous reefs with only the smallest margin of safety, they came at last to the jettied outlet of Crescent Bay.

The roar of the breakers sounded ominously close through the gray canopy of fog. The little craft rocked briskly in the trough of the swell as Lang threw the wheel over and headed out to sea. Flashing a small light over the compass, which served as an improvised binnacle, he peered intently at the instrument. Then he spoke softly to the man forward.

"Take the wheel, Joe."

When the Mexican had relieved him Lang bent low over the compass and examined his watch. Then he joined Gregory.

"Twelve o'clock," he announced. "We've got to make Diablo before daybreak. Sixty-five miles in less than four hours. That means hurry in weather like this."

He turned to the man at the wheel.

"Crowd her, Joe," he called. "We're taking

chances to-night. If we hit anybody we might as well hit hard."
