air bubbles in it; if this could once be accomplished, as I understood,
or misunderstood, brass could be used in art-printing to a degree
hitherto impossible. I dare say I have got it wrong, but I am not
mistaken as to Clemens's enthusiasm for the process, and his heavy losses
in paying its way to ultimate failure. He was simultaneously absorbed in
the perfection of a type-setting machine, which he was paying the
inventor a salary to bring to a perfection so expensive that it was
practically impracticable. We were both printers by trade, and I could
take the same interest in this wonderful piece of mechanism that he
could; and it was so truly wonderful that it did everything but walk and
talk. Its ingenious creator was so bent upon realizing the highest ideal
in it that he produced a machine of quite unimpeachable efficiency. But
it was so costly, when finished, that it could not be made for less than
twenty thousand dollars, if the parts were made by hand. This sum was
prohibitive of its introduction, unless the requisite capital could be
found for making the parts by machinery, and Clemens spent many months in
vainly trying to get this money together. In the mean time simpler
machines had been invented and the market filled, and his investment of
three hundred thousand dollars in the beautiful miracle remained
permanent but not profitable. I once went with him to witness its
performance, and it did seem to me the last word in its way, but it had
been spoken too exquisitely, too fastidiously. I never heard him devote
the inventor to the infernal gods, as he was apt to do with the geniuses
he lost money by, and so I think he did not regard him as a traitor.

In these things, and in his other schemes for the 'subiti guadagni' of
the speculator and the "sudden making of splendid names" for the
benefactors of our species, Clemens satisfied the Colonel Sellers nature
in himself (from which he drew the picture of that wild and lovable
figure), and perhaps made as good use of his money as he could. He did
