Soon after this they saw a landing-place on the left bank. Stopping to examine it, they discovered a trail leading through a fringe of bushes, behind which was an Indian field covering an old shell mound, and in a high state of cultivation. In it were growing sweet-potatoes, melons, squashes, sugar-cane, and beans—a supply of which they would gladly have purchased had the proprietors been present. As they were not, and necessity knows no law, our canoemen helped themselves to what they needed, and when they left, the load of the cruiser was materially increased.
At length they heard the dull boom of surf, and realized that only a narrow strip of land separated them from the ocean. Late in the afternoon they reached the mouth of the river, and the boys uttered joyous shouts as they looked out over its bar and saw a limitless expanse of blue waters, unbroken by islands, glistening in the light of the setting sun.
With light hearts they went into camp on the inner side of the sandy point separating the quiet waters on which they had been floating from the long swells of the open sea. They intended running out of the river and down the coast in the morning, for from their surroundings, as well as from the general course they had taken through the 'Glades, the Lieutenant was satisfied that they must be considerably to the north of Cape Florida.
The boys determined to sleep in their canoes that night, and rigged up the little-used striped canoe tents for that purpose. While they were doing this, and the Lieutenant was pitching his own tent on shore, and the others were collecting drift-wood on the beach, there came a hail from across the river.
"Hello there! Bring a boat over here, can't ye?"
It was the first white man they had seen since leaving the Transit, and going over in the cruiser, Sumner brought him back. He proved to be a barefooted boy, a year younger than Worth, and yet he was the mail-carrier over the most southerly land route, and one of the most lonesome, in the United States. It is the seventy-mile stretch between Lake Worth and Biscayne Bay, and every week this boy or his younger brother walked the whole distance and back along the beach, with a mail-sack on his back. He had to cross the mouths of two rivers, for which purpose he kept an old skiff at each one. It sometimes happened, as in the present case, that some other beach traveller would appropriate his boat, and leave it on the wrong side. Then, unless fortunate enough to find some one to set him across, he would be obliged to brave the sharks and other sea-monsters, with which these rivers swarm, and swim over after his own boat. Along his route were three houses of refuge, situated twenty miles apart, and belonging to the Life-saving Service. Each of them contained a single keeper, and these were the only persons seen by the lonely mail-boy while on his toilsome tramps.
The boy was greatly interested in the canoes, which he declared were the neatest little tricks he ever did see, but he scouted the idea of sleeping in them. "Why," said he, "some of them sharks or porpusses what uses round here nights will run inter ye an' upsot ye quicker'n wink."
He was amazed that they should cruise in such tiny craft, and begged them not to think of attempting to run down the coast in them. On the whole he regarded our young canoemates as being particularly daring and reckless fellows, and they regarded him in much the same way, though he made light of his lonely beach tramps, on which he often met bears, panthers, or other wild animals.
He told them that they were about twenty-five miles north of Cape Florida; that there was a "station" on the beach six miles north of them; that turtle were beginning to lay eggs, and bears to frequent the beach in search of them; that sharks grew larger in those very waters than anywhere else on the coast; and that an easterly wind would blow in the morning, which would prevent their crossing the bar. Having delivered himself of this information, and saying that he must make the station that night, the boy slung his mail-sack over his shoulders, and started off at a brisk pace up the soft shelving beach.
