The Irene's anchor was dropped behind the bar that lies opposite the mouth of the river, and Molly and the boys went out in the skiff to call on a family of pelicans which were keeping house on a little coral key, surrounded by oyster reefs, between Rodgers and Broad rivers. As the skiff neared the key the old birds flew lazily away and lit on a mud-flat a hundred yards distant, but the pelican children waddled around on the oyster reef without showing much alarm until Dick caught one, when the indignant bird struck him with its big bill and punched holes in his hat. As the tide fell the oyster bars were uncovered, the water shoaled on the mud-flats, and the boys gathered oysters from one, and clams weighing from half a pound to four pounds each from the other.
A fire was built on the reef, bread and coffee brought from the Irene, and Mr. Barstow and Captain Hull invited to a picnic supper which they were polite enough to say they enjoyed greatly. After supper Molly and the boys took a walk on the beach on the north side of Rodgers River and amused themselves by chasing the crabs that were skurrying along close to the shore to keep out of the way of their enemies. They had a lot of fun, but caught no crabs, until Dick went back to the Irene for a scoop-net and a bucket, which he soon filled with the crustaceans. Molly had never before seen shell-fish growing on trees, so Dick cut a few oyster-bearing branches from a mangrove tree and roasted bunches of the bivalves on the beach. When the sputtering of the oysters on the branch told Dick they were cooked, he hauled the limb from the coals, sat down with his companion on the beach, and with sharpened sticks the young people picked the roasted oysters from their shells, while Dick told the girl of that other picnic on the coast near-by after the waterspout had wrecked the Etta. They talked after the oysters were eaten and the fire had gone out, until Ned's voice came to them:
"Do you kids expect to settle here and grow up with the country? Don't you know it's 'most night, the tide's been right for the river for an hour, and everybody is waiting for you?"
When they reached the Irene, Mr. Barstow proposed putting off their start until morning to give Molly and him a chance to see the river as they sailed up it. Mr. Barstow replied to a quizzical look from his son:
"Of course, this doesn't come out of your time, Ned. You are to have your full three days."
"Maybe you'd like to see some fire-hunting," said the captain. "There are 'gators in these rivers, and there's time before the moon rises to find one or two. If you don't want one killed I'll fire a blank cartridge at him, unless you'd like to shine the eyes of one yourself."
"I don't think I'll try any fire-hunting, but I should like to see it done," said Mr. Barstow.
Dick was proud of his sculling, and at his request it was arranged that he should scull the skiff for the captain, while Ned was to pole the little motor-boat, in which his father and sister would go with him. Before they had gone far Dick found that he had overestimated his strength, and that handling the heavy sculling oar was too much for him. Mr. Barstow offered to pole the motor-boat, and Ned took Dick's place at the oar in the skiff, where Dick remained as a passenger. They entered Broad River and Ned sculled slowly along the bank, while the beam of light from the lantern, which was bound to the captain's forehead, played along the surface of the water under the mangroves that overhung the banks and sometimes swept the banks above the water. In the shallow places mullet leaped wildly as the rays of the bull's-eye lantern fell on them, while porpoises sniffed and tarpon splashed in their light. Sculling was hard work for Ned, who had none of the easy and graceful swing with which Dick threw his weight on a sculling oar, a skill which he had acquired during his life on the sponger. Several times the oar jumped out of the scull hole in the skiff, and once Ned nearly went overboard. But a little extra noise didn't much disturb wild creatures that were fascinated by the light; and on the land 'coons sat motionless, two dots of greenish light told of a hypnotized wildcat, and when all on the skiff saw the light reflected from two big, round eyes, while the captain held the beam from the lantern steadily upon them, Dick whispered:
"What is it?"
