“I’ve got the best water around these parts,” persisted Jack, as the Crystal Spring drifted by. “It’s spring water right out of the ground this morning.”

The man grinned. “That’s what they all say,” he jeered. “And it all tastes like bilge, too.”

“Mine don’t. Better try some. Let me fill up a tank for you, sir.”

“All full, I tell you.” The man turned away, Jack swung the helm over and the Crystal Spring began her day’s cruise in and out of the shipping. It was almost eleven before Jack made his first sale. A Portuguese fisherman bargained a good ten minutes. Then the Crystal Spring was made fast, the hose was lifted to the schooner’s deck and pulled down a forward hatchway and Jack, attaching the long handle to the pump, began his labor. It wasn’t easy work, but Jack’s muscles were used to it, and, as the fisherman had only one butt to fill, it was soon done. Then Jack took his pay, recoiled his hose, cast loose and went on again. What breeze there had been earlier in the day had almost died away and the sloop’s progress was slower than ever. Now and then Jack caught sight of the Morning Star, as the rival water boat was poetically named, chugging its way about the harbor. But even the Morning Star wasn’t doing much business today. At noon Jack made fast to the stern of a lumber schooner near the coal wharf and ate his lunch. It was pleasant enough there in the sun with so much to watch, and the lunch that Aunt Mercy had put up tasted awfully nice, just as it always did, but Jack wished that trade was brisker in his line of business. And just when he was thinking that there was a hail across the basin.

“Water boat, ahoy!” came a voice.


CHAPTER II
A Rescue

Jack jumped to his feet, dropping two of Aunt Mercy’s best doughnuts, and looked about him. The hail came again and Jack saw Desco Benton waving from the Hetty and Grace.

“Right-o!” he called, and quickly cast loose. It took the Crystal Spring almost five minutes to half drift and half sail across to the hand-liner, and all the way Jack wondered what Desco wanted of him. When he was alongside the master of the Hetty and Grace appeared at the rail again.
