It was so near morning, however, that they lingered to scan the shore. Then it was observed that a pearly mist was rising from the swamp lands and spreading out over the water. It was almost like a fog which the morning breeze would dispel after a while. Rolling like smoke it hung so low that the topmast of the sloop rose above it although her hull was like the gray ghost of a vessel.
"No sign of wind as yet," said Joe, holding up a wetted finger, "and that red sunset bespoke a calm, hot day. This odd smother o' mist may stay a couple of hours. Will ye venture it with me, Jack?"
"Gladly! Over we go, before the watch is flogged awake by the bos'n's mate."
They crept aft to the high stern and paid out a coil of rope until it trailed in the water beneath the railed gallery which overhung the huge rudder. Joe belayed his end securely and slid over like a flash, twisting the rope around one leg and letting himself down as agile as a monkey. Without a splash he cast himself loose and Jack followed but not so adroitly. When he plopped into the water the commotion was like tossing a barrel overboard, but nobody sounded an alarm.
They clung to the rusty rudder chains and listened. The ship was all quiet. Then out into the mist they launched themselves, swimming almost submerged, dreading to hear an outcry and the spatter of musket balls. But the veiling mist and the uncertain light of dawn soon protected the fugitives. It was slow, exhausting progress, hampered as they were by their breeches and shoes which could not be discarded. They tried to keep a sense of direction, striking out for the mouth of the creek in which the pirogue had been moored, but the tide set them off the course and the only visible marks were the spars of the ship behind them and the sloop's topmast off to one side.
Jack swam more strongly and showed greater endurance because he had the beef and had been better nourished all his life than the scrawny young powder boy who was more like a lath. Now and then Jack paused to tread water while his shipmate clung to his shoulder and husbanded his waning strength, with that indomitable grin on his freckled phiz. Of one thing they were thankful, that the tide was bearing them farther away from the pirates' camp, which was now as still as though the sleepers were dead men.
"Blood and bones, but I have swum a league a'ready," gurgled Joe during one of the halts.
"Shut your mouth or you'll fill up to the hatch and founder," scolded Jack. "I see trees in the mist. The shore is scarce a pistol shot away."
"I pray my keel scrapes soon," spluttered the waterlogged Hawkridge as he kicked himself along in a final effort.
Huzza, their feet touched the soft ooze and they fell over stumps and rotted trunks buried under the surface. Scratched and beplastered with mud, they crawled out in muck which gripped them to the knees, and roosted like buzzards upon the butt of a prostrate live-oak.
