"We'll never reach the Capes in daylight at this rate," said Hawley. "The days are getting much shorter."

"That's so," said Alec. "Yesterday was the twenty-first of August. It's just two months since the longest day and the days are shortening fast."

Slowly the Rebecca forged ahead. Even the cool breath of the water could scarcely make the sun's heat endurable. Under the fierce rays the smell of paint became almost overpowering. The tar on ropes and rigging almost melted and ran. The fleecy clouds along the horizon bulked larger and larger. Slowly they rose toward the zenith. Late afternoon came. The ship was still far from the Capes. Captain Rumford studied the clouds carefully.

"We'll pull in behind the breakwater when we get there, Jim," he said quietly. "I think that storm will be a rip snorter. We might as well be on the safe side."

They went on. Gradually the sun's rays grew feebler. Gusts of vapor were hurtling across the sky, curtaining the fiery beams. The sky turned a peculiar greenish-copper color. The thunder-heads mounted ever higher. Then the sun was shut from sight. It grew dusk. Darkness came, as sudden as the dropping of a curtain. Afar off, flashes of lightning rent the clouds. Thunder rumbled ominously in the distance. The wind died away. It grew calm as midnight. The Rebecca rolled idly, her sheets flapping. The men got into their oilskins.

"Better shorten sail," said the shipper.

They ran to the halyards. Down came the great canvases. Nimbly they fastened the reef-points and made all as snug as possible.

"Now let her blow," said the shipper. "The more wind, the faster we go. We'll reach the breakwater and heave to. I kind of wish we had a heavier anchor, though."

None too soon had the Rebecca shortened sail. Afar off an ominous rushing sound was heard. The wind began to come in short puffs. Flash after flash of lightning illumined the angry clouds. The roaring sound grew louder. It came on with the speed of an express-train. Over the waves swept a sheet of falling rain like a very wall of water. Alec closed the companionway and jammed on the hatch covers. In another moment the storm was upon them.
