during which I marvelled over what I had seen, scarcely crediting my
memory or my senses. In the morning, I went back to the crater, and
with some tools that had been left on shore contrived to dig somewhat
deeply among the _debris_ with which it was filled. I found very
little that could enlighten me except pieces of glass, of various
metals, of wood, some of which seemed apparently to have been portions
of furniture; and one damaged but still entire relic, which I
preserved and brought away with me."

Here the Colonel removed a newspaper which had covered a portion of
his table, and showed me a metallic case beaten out of all shape, but
apparently of what had been a silvery colour, very little rusted,
though much soiled. This he opened, and I saw at once that it was of
enormous thickness and solidity, to which and to favouring
circumstances it owed its preservation in the general ruin he
described. That it had undergone some severe and violent shock there
could be no question. Beside the box lay a less damaged though still
seriously injured object, in which I recognised the resemblance of a
book of considerable thickness, and bound in metal like that of the
case. This I afterwards ascertained beyond doubt to be a metalloid
alloy whereof the principal ingredient was aluminium, or some
substance so closely resembling it as not to be distinguishable from
it by simple chemical tests. A friend to whom I submitted a small
portion broken off from the rest expressed no doubt that it was a kind
of aluminium bronze, but inclined to believe that it contained no
inconsiderable proportion of a metal with which chemists are as yet
imperfectly acquainted; perhaps, he said, silicon; certainly something
which had given to the alloy a hardness and tenacity unknown to any
familiar metallurgical compound.
