A low bank of fresh green willows for
background and effective contrast - for she stood against
them - and above and out of them projected the eager faces
and white shoulders of two smaller girls.
Toward noon we heard the inspiring cry:
"Sail ho!"
"Where away?" shouted the captain.
"Three points off the weather bow!"
We ran forward to see the vessel. It proved to be
a steamboat - for they had begun to run a steamer up
the Neckar, for the first time in May. She was a tug,
and one of a very peculiar build and aspect. I had
often watched her from the hotel, and wondered how she
propelled herself, for apparently she had no propeller
or paddles. She came churning along, now, making a deal
of noise of one kind or another, and aggravating it every
now and then by blowing a hoarse whistle. She had nine
keel-boats hitched on behind and following after her
in a long, slender rank. We met her in a narrow place,
between dikes, and there was hardly room for us both in the
cramped passage. As she went grinding and groaning by,
we perceived the secret of her moving impulse. She did
not drive herself up the river with paddles or propeller,
she pulled herself by hauling on a great chain.
This chain is laid in the bed of the river and is only
fastened at the two ends.
