le or something that would fling you forward with
damaging results. Frequently that is what happened. The word "header"
seems to have grown out of that early bicycling period. Perhaps Mark
Twain invented it. He had enough experience to do it. He always
declared afterward that he invented all the new bicycle profanity that
has since come into general use. Once he wrote:

There was a row of low stepping-stones across one end of the street,
a measured yard apart. Even after I got so I could steer pretty
fairly I was so afraid of those stones that I always hit them. They
gave me the worst falls I ever got in that street, except those
which I got from dogs. I have seen it stated that no expert is
quick enough to run over a dog; that a dog is always able to skip
out of his way. I think that that may be true; but I think that the
reason he couldn't run over the dog was because he was trying to. I
did not try to run over any dog. But I ran over every dog that came
along. I think it makes a great deal of difference. If you try to
run over the dog he knows how to calculate, but if you are trying to
miss him he does not know how to calculate, and is liable to jump
the wrong way every time. It was always so in my experience. Even
when I could not hit a wagon I could hit a dog that came to see me
practise. They all liked to see me practise, and they all came, for
there was very little going on in our neighborhood to entertain a
dog.

He conquered, measurably, that old, discouraging thing, and he and
Twichell would go on excursions, sometimes as far as Wethersfield or to
the tower. It was a pleasant change, at least it was an interesting one;
but bicycling on the high wheel was never a popular diversion with Mark
Twain, and his enthusiasm in the sport had died before the "safety" came
along.

He had his machine sent out to Elmira, but there were too many hills in
Chemung County, and after one brief excursion he came in, limping and
pushing his wheel, and did not try it again.

To return to Cable. When the 1st of April (1884) approached he concluded
it would be a good time to pay off his debt of gratitude for his recent
entertainment in the Clemens's home. He went to work at it
systematically. He had a "private and confidential" circular letter
printed, and he mailed it to one hundred and fifty of Mark Twain's
literary friends in Boston, Hartford, Springfield, New
