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.
