As soon, however, as the tree was cut down, it was evident that it was not intended to be used as a mast, for Forester began at once to cut it up into lengths of about two feet long. What could be his design, the boys were utterly unable to imagine. He said nothing, but ordered the boys to take these lengths, one by one, and put them into the boat. There were five in all. Then he ordered the crew on board again. Marco got in last. When all were seated, the order was given to shove off, the oars were _tossed_--then _let fall_ into the water. He ordered them to _back water_ first, by which manoeuver the boat was backed off from the land into deep water. Then he commanded them to _give way_, and at the same time bringing the stern of the boat round by his paddle, the boat was made to shoot swiftly down the stream. The boat went rapidly forward along the shores of the pond, and presently, on coming round a wooded point, the mills appeared in sight. As they approached the mills, they kept pretty near the shore, and at length landed just above the dam. Forester ordered the crew ashore, at a place where there was a road leading down to the water's edge. This road was made by the teams which came down to get logs and lumber from the water. At Forester's direction, the boys drew the bow of the boat up a little way upon the land. Then he ordered the boys to take out the pieces of the stem of the little tree, and he placed one of them under the bow as a roller. The boys then took hold of the sides of the boat, three on each side, each boy opposite to his own row-lock, while Marco stood ready to put under another roller. The ascent was very gradual, so that the boat moved up easily, and the boys were very much surprised and delighted to see their boat thus running up upon the land. It seemed to them an exercise of great power to be able to take so large a boat so easily and rapidly up such an ascent upon the land. They were aided to do it by two principles. One was the combination of their strength in one united effort, and the other was the influence of the rollers in preventing the friction of the bottom of the boat upon the ground. Presently the whole length of the boat was out of water and resting on four rollers, which Marco had put under it, one by one, as it had advanced. Forester would then call out, "_Ahead with her!_" when the boys would move about two steps. Then Forester would give the command, "_Hold on_," and they would stop. By this time one of the rollers would come out behind, and Marco would take it up and carry it round forward, and place it under the bow, and Forester would then say, "_Ahead with her!_" again, and the boat would immediately advance again up the acclivity.
