It was a different matter, punting this home-made boat around the waters of a pond on a calm summer's day, and striking out with it in a blinding storm across the flooding lowlands of the Mississippi River. Again his father's warning not to be foolhardy, came to Ross's remembrance, and, together with it, the Weather Bureau man's caution. None the less, the boy knew well that his father would never bid him hold back from a piece of work that was dangerous or difficult when life was at stake. The boat was half full of water from the pouring rain. Ross bailed it out with a cocoanut-shell to which a handle had been affixed, evidently a home-made bailer of Anton's manufacture, and, as soon as it was clear of water, dragged it to the border of the current and launched it. The craft floated crankily, it was true, but it floated, and, so far as the boy could tell, it seemed fairly water-tight. Jumping out again, Ross swung himself into the water and shoved the boat along beside him. He saw the value of wading as far as possible, for he knew that, as long as his feet were on the bottom, he could govern his direction. To what extent he might be able to stem the current by the use of oars in a boat of that character, he did not know. Rex, however, was convinced that the boat had been secured expressly for him, and, as soon as Ross came near enough to the shore, the dog bounded through the shallow water in long leaps, swimming the last few feet, and put his paws on the gunwale. Ross picked up the terrier and heaved him into the boat. Rex gave a snort of satisfaction, shook himself so that he sent a trundling spray of water clear in his master's face and then took his post in the bow of the boat and set himself to barking with all his might and main. It seemed almost as though he really knew that he was at the head of a rescue expedition and wanted to convey the information. When at last Rex ceased barking, which was not for some minutes, Ross gave a shout. Instantly, at one of the upper windows, something white appeared. In the darkness the boy could not tell what it might be, but he guessed, and rightly, that it was Anton's shirt, and he heard again, though faintly, the answering call across the river. "Keep up your nerve, Anton," he yelled, through the storm, "I'll be over there in a minute." Faintly, again, came the answering cry, "Hello, Ross! Is that you? I wondered who it was that was coming."
