onlight as it had been
in the daytime. The streets were narrow and roughly paved,
and there was not a sidewalk or a street-lamp anywhere.
The dwellings were centuries old, and vast enough for hotels.
They widened all the way up; the stories projected
further and further forward and aside as they ascended,
and the long rows of lighted windows, filled with little bits
of panes, curtained with figured white muslin and adorned
outside with boxes of flowers, made a pretty effect.
The moon was bright, and the light and shadow very strong;
and nothing could be more picturesque than those curving
streets, with their rows of huge high gables leaning
far over toward each other in a friendly gossiping way,
and the crowds below drifting through the alternating blots
of gloom and mellow bars of moonlight. Nearly everybody
was abroad, chatting, singing, romping, or massed in lazy
comfortable attitudes in the doorways.

In one place there was a public building which was
fenced about with a thick, rusty chain, which sagged
from post to post in a succession of low swings.
The pavement, here, was made of heavy blocks of stone.
In the glare of the moon a party of barefooted children
were swinging on those chains and having a noisy good time.
They were not the first ones who have done that;
even their great-great-grandfathers had not been the first
to do it when they were children. The strokes of the bare
feet had worn grooves inches deep in the stone flags;
it had taken many generations of swinging children to
accomplish that. Everywhere in the town were the mold
and decay that go with antiquity, and evidence of it;
but I do not know that anything else gave us so vivid
a sense of the old age of Heilbronn as those footworn
grooves in the paving-stones.

CHAPTER XIII
[My Long Crawl in the Dark]

When we got back to the hotel I wound and set the
pedometer and put it in my pocket, for I was to carry
it next day and keep record of the miles we made.
The work which we had given the instrument to do during
the day which had just closed had not fatigued it perceptibly.

We were in bed by ten, for we wanted to be up and away on
our tramp homeward with the dawn. I hung fire, but Harris
went to sleep at once. I hate a man who goes to sleep
at once; there is a sort of indefinable something about it
which is not exactly an insult, and yet is an insolence;
and one which is hard to bear, too. I lay there fretting
over this injury
