Hundreds of puns had been made on his pen-name, but this was probably his
first and only attempt, and it still remains the best.

They arrived in Sweden early in July and remained until October. Jean
was certainly benefited by the Kellgren treatment, and they had for a
time the greatest hopes of her complete recovery. Clemens became
enthusiastic over osteopathy, and wrote eloquently to every one, urging
each to try the great new curative which was certain to restore universal
health. He wrote long articles on Kellgren and his science, largely
justified, no doubt, for certainly miraculous benefits were recorded;
though Clemens was not likely to underestimate a thing which appealed to
both his imagination and his reason. Writing to Twichell he concluded,
with his customary optimism over any new benefit:

Ten years hence no sane man will call a doctor except when the knife

Twichell was traveling in Europe that summer, and wrote from Switzerland:

I seemed ever and anon to see you and me swinging along those

that every turn brought into view-talking, talking, endlessly
talking the days through-days forever memorable to me. That was
twenty-one years ago; think of it! We were youngsters then, Mark,
and how keen our relish of everything was! Well, I can enjoy myself
now; but not with that zest and rapture. Oh, a lot of items of our
tramp travel in 1878 that I had long forgotten came back to me as we
sped through that enchanted region, and if I wasn't on duty with
Venice I'd stop and set down some of them, but Venice must be
attended to. For one thing, there is Howells's book to be read at
such intervals as can be snatched from the quick-time march on which
our rustling leader keeps us. However, in Venice so far we want to
be gazing pretty steadily from morning till night, and by the grac
