“Yes.” replied Forester.  “You must have two oars to guide a boat, but you can do it with one paddle.  Therefore, if you can have but one, a paddle is better than an oar.  There is another advantage in a paddle; that is, in using it, your face looks the way that you are going.”

“Yes,” rejoined Marco, “that is a great advantage.”

“In rowing, you must sit with your back to the bow of the boat, and look over your shoulder to see where you are going.”

“Yes,” said Marco, “unless you have a steersman.”

“True,” replied Forester.  “When you have several men to row, and one to steer, you get along very well with oars, but in case of only one man, there is an advantage in a paddle.  There is still another point to be considered,—­a paddle is better for a narrow boat and oars for wide ones.”

“Why so?” asked Marco.

“Because,” said Forester, “a certain width is required in a boat in order to work oars well.  The oarsman must sit upon the seat, and extend the oar off upon one side of the boat, and there must be a certain distance between the part which he takes hold of, and the row-lock, in order to work to advantage.  But it is no matter how narrow the boat is if he has a paddle, for he holds it perpendicularly over the side.”

“So paddles are better,” said Marco, “for one kind of boat, and oars for another.”

“Yes,” replied Forester, “and paddles are better for one kind of navigation, and oars for another.  Oars require greater breadth of water to work in.  In a narrow, crooked stream flowing among logs and rocks, oars would not answer at all.  But with a paddle a man can worm a boat through anywhere.”

“That is, if it is only wide enough for the boat to go,” said Marco.

“Of course,” replied Forester.  “The paddle itself requires no additional space.  But oars extend so far laterally”—­

“Laterally?” asked Marco.

“Yes,” rejoined Forester; “that is, on each side.  Oars extend so far on each side, that they require a great breadth of water.  If you attempt to go through a narrow place, the oars would strike.”

“Why, no,” said Marco.  “You can give orders to trail oars.”

“I don’t know any thing about that,” said Forester.

“That’s a beautiful manoeuver,” said Marco, “only it is hard to do.  You see, you order them to give way hearty, so as to get a good headway, till just as you get to the narrow place, and then trail is the word.  Then the oarsmen all whip their oars out of the row-locks in an instant, and let ’em trail alongside under the boat’s counters, and she shoots through the narrow place like a bird.”

Marco became very enthusiastic in describing this manoeuver, but Forester did not get a very clear idea of it, after all.

“You’ll teach it to us,” said Forester, “when we get our oars and a good boat’s crew of boys.  At any rate, a boat can be paddled continuously through a narrow space, better than it can be rowed.  Therefore, paddles are generally used on rivers, where there are many narrow places to pass through.  Indians and savages almost always use paddles, for they navigate many intricate and narrow passages of water.”
