irls and women go back
and forth."

For while they had been looking at the boat, as they gradually
approached the spot, they had seen it pass to and fro with many
passengers, who, though they were very neatly dressed, were evidently by
no means wealthy or fashionable people.

So Mr. George and Rollo went to the margin of the road where the ferry
boat had its little landing place, and when it came up they stepped on
board. The ferryman could only talk Dutch, and so Mr. George could not
ask him what was to pay. The only thing to be done was to give him a
piece of silver, and let him give back such change as he pleased. Mr.
George gave him a piece of money about as big as half a franc, and he
got back so much change in return that he said he felt richer than he
did before.

At another place they came to a bridge that led across the canal. This
bridge turned on a pivot placed out near the middle of the canal, so
that it could be moved out of the way when there was a boat to go by. A
man was turning it when Mr. George and Rollo came along. They stopped to
witness the operation. They were quite amused, not merely with the
manoeuvring of the bridge, but with the form and appearance of the
boat that was going through. It seemed to be half boat and half house.
There was a room built in it, which rose somewhat above the deck, and
showed several little windows with pretty curtains to them. There was a
girl sitting at one of these windows, knitting, and two or three
children were playing about the deck at the time that the boat was going
through the bridge.

Farther on the party came to an immense wind mill, which was employed in
pumping up water. This wind mill, like most of the others, was built of
brick. It rose to a vast height into the air, and there its immense
sails were slowly revolving. The wind mill was forty or fifty feet in
diameter at the base, and midway between the base and the summit was a
platform built out, that extended all around it. The sails of the mill,
as they revolved, only extended down to this platform, and the platform
itself was above the roofs of the four-story houses that stood near.

At the foot of this wind mill Mr. George and Rollo could see the water
running in under it, through a sluice way which led from a low canal,
and on the other side they could see it pouring out in a great torrent,
into a higher one.
