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."
By this time they began to draw near the mill. They landed near some
great logs which were floating in the water, ready to be drawn up into
the mill and sawed. They went up the bank and thence into the mill.
The man who owned the boat, was tending the mill. When he wanted a
log, he would take the end of a long chain down a sloping plane of
planks which led to the water, and fasten it to a log. The other end
of the chain was fastened round an axle in the mill, and when all was
ready, the man would set the axle in motion by the machinery, and that
would draw the log up. When the log was in the mill, the man would
roll it over into its place, on a long platform of timber, where it
was to be sawed. Then he would set the saw machinery in motion, and
the platform would begin to move forward, and the saw at the same time
to go up and down, sawing the log as it advanced. Thus it would saw
it through, from end to end, and then, by reversing the motion of the
machinery, the log was carried back again. The man would then move it
a little to one side, just far enough for the thickness of the board
which he wished to make, and then begin to saw again. He moved the log
by means of an iron bar with a sharp point, which he struck into the
end of the log, and thus pried it over, one end at a time.
