Marco wished to have Forester teach the boys how to back water, and to trail oars, and to put the oars apeak, and to perform various other evolutions. But Forester was very slow in going on to new manoeuvers before the old ones were made perfectly familiar. He accordingly spent nearly an hour in rowing about the pond, up and down, to make the boys familiar with the stroke. He found, as is, in fact, universally the case with beginners in the art of rowing, that they were very prone to row faster and faster, that is, to accelerate their strokes, instead of rowing regularly, keeping continually the same time. They gradually improved, however, in respect to this fault, and by the middle of the afternoon Marco began to think that they were quite a good crew. They practiced several new evolutions during the latter part of the afternoon, and just before tea time they all went home, much pleased with the afternoon's enjoyment, and with the new knowledge and skill which they had acquired. They also planned another excursion the following week. Chapter X. An Expedition. Forester and Marco got their boat's crew well trained in the course of a week or two, and one pleasant day in September they planned a long expedition in their boat. The boys collected at the house of the owner of the boat, at one o'clock. Two of them carried a large basket which Forester had provided. It was quite heavy, and they did not know what was in it; but they supposed that it was a store of some sort of provisions for a supper, in case they should be gone so long as to need a supper. Forester carried a hatchet also. At the proper word of command, the boys got into the boat and took their several stations. Marco took his place forward to act as bowman. It is the duty of the bowman to keep a lookout forward, that the boat does not run into any danger; and also, when the boat comes to land, to step out first and hold it by the painter, that is, the rope which is fastened to the bow, while the others get out. Marco had a pole, with an iron spike and also an iron hook in the end of it, which he used to _fend off_ with, as they called it, when the boat was in danger of running against any obstacle. This was called a boat-hook. "_Attention!_" said Forester, when the boys were all seated. "_Toss!_" Hereupon the boys raised the oars into the air, ready to let them down into the water. "_Let fall!_" said Forester. The oars all fell gently and together into their places. "_Give way!_" said Forester. The boat began immediately to glide rapidly over the water, under the impulse which the boys gave it in rowing. "_Crew at ease_," said Forester.
