A sound of hammering came from one of the schooners at anchor near the landing. "I hear Captain Tony," Bascom said. "I reckon I'll get out here."

"I didn't guess yo'd pass by de little Mystery," Narcisse answered, with a good-natured grin. All Potosi was used to Bascom's devotion to the boat which he and Captain Tony had won by bringing it safely through the great Gulf storm the year before. Narcisse was no sooner out of sight, however, than Bascom forgot even the Mystery in the excitement it had been so hard to suppress.

"Cap'n Tony," he cried, fairly stammering with eagerness—"Cap'n Tony— I—I—found a buried cannon on the croaker bank!"

"W-w'at?" said Captain Tony, wondering.

"It's all crusted up with barnacles, but I know it's a cannon," Bascom insisted. "I felt all round it, and inside of it too."

Captain Tony lifted his cap a little and then drew it down over his eyes again incredulously. "I guess it can't be true," he said at last. "I have never hear me 'bout any cannon sunk in de bay, an' I know all de story of ole time."

Bascom was prancing up and down in a perfect fever of impatience. "It must have been ever so long ago, the pirates or the Spaniards," he said. "An' if there's a cannon there must ha' been a ship sunk there, an' if there was a ship there must be a treasure, an' we're not a-goin' to say nothin' to nobody, but we're a-goin' to fish it all up!"

Captain Tony put a hand on Bascom's shoulder to keep him from squirming. "Yo' boy," he said, with the warm-hearted indulgence he always felt for the young waif who had become his business partner, "I doan t'ink me dat if dere is a cannon dere it will run off—not dis evenin'; an' faw de treasure, it was without doubt mo' easy to remove. Mos' likely it run away good w'ile ago."

"Well, I'm goin' to look an' be sure," Bascom said. "We must get the cannon, anyways, and have her on the Mystery."

The Captain chuckled. "Us'es'll raise sail," he said, "an' jus' run out befo' de breeze dies down." They might more easily have rowed, but Tony and Bascom seldom went anywhere without the Mystery, except on land.
