"Oh, Caesar?" said he. "To be sure. He's as much a legend of these keys as Lafitte is of New Orleans. He was an escaped slave, who scraped together a dozen fellow-ruffians, black and white and yellow--mostly yellow--about a century ago, and stole a long boat or a broken-down sloop, and started in at the trade of pirate. He didn't last long. And there's no proof he ever had any special success. But he's the sea-hero of the conchs. They've named a key and a so-called creek after him, and in my father's time there used to be an old iron ring in a bowlder known as 'Caesar's Rock.' The ring was probably put there by oystermen. But the conchs insisted Caesar used to tie up there. Then there's the 'Pirates' Punchbowl,' off Coconut Grove. Caesar is supposed to have dug that. He--" An enormous sailfish--dazzlingly metallic blue and silver--broke from the calm water just ahead, and whirled high in air, smiting the bay again with a splash that sounded like a gunshot. "That fellow must have been close to seven feet long," commented Milo as the two men watched the churned water where the fish had struck. "He's the kind you see when you aren't trolling. He's after a school of ballyhoos or mossbunkers .... There's Roustabout Key just ahead," he finished as their launch rounded an outcrop of rock and came in view of a mile-long wooded island a bare thousand yards off the weather bow. A mangrove fringe covered the shoreline, two thirds of the way around the key. At the eastern end was a strip of snowy beach backed by an irregular line of coconut palms, and with a very respectable dock in the foreground. From the pier a wooden path led upward through the scattering double row of palms to a corrugated iron hut, with smaller huts and outbuildings half seen through the foliage-vistas beyond. "I've some fairly good mango trees back yonder," said Standish as he brought the launch alongside the dock's wabbly float, "and grapefruit that is paying big dividends at last. The mangoes won't be ripe till June, of course. But they're sold already, to the last half-bushel of them." "'Futures,' eh?" suggested Gavin. "'Futures,'" assented Milo. "And 'futures' in farming are just about as certain as in Wall Street. There's a mighty gamble to this farm-game." "How long have--?" began Gavin, then stopped short and stared. One or two negro laborers had drifted down toward the dock, as the boat warped in at the float. Now, from the corrugated iron hut appeared a white man, who, at sight of the boat, broke into a limping run and was in time to catch the line which Milo flung at him. The man was sparsely and sketchily clad. At first, his tanned face seemed to be of several different colors and to have been modeled by some bungling caricaturist. Yet, despite this eccentricity of aspect, something about the obsequiously hurrying man struck Brice as familiar. And, all at once, he recognized him.
