ng of the year 1866 the heat was very great, but
the hunting in the forests did not stand still. Agouties, peccaries,
capybaras, kangaroos, game of all sorts, actually swarmed there, and
Spilett and Herbert were too good marksmen ever to throw away their shot
uselessly.

Cyrus Harding still recommended them to husband the ammunition, and he
took measures to replace the powder and shot which had been found in
the box, and which he wished to reserve for the future. How did he know
where chance might one day cast his companions and himself in the
event of their leaving their domain? They should, then, prepare for the
unknown future by husbanding their ammunition and by substituting for it
some easily renewable substance.

To replace lead, of which Harding had found no traces in the island, he
employed granulated iron, which was easy to manufacture. These bullets,
not having the weight of leaden bullets, were made larger, and each
charge contained less, but the skill of the sportsmen made up this
deficiency. As to powder, Cyrus Harding would have been able to make
that also, for he had at his disposal saltpeter, sulphur, and coal; but
this preparation requires extreme care, and without special tools it is
difficult to produce it of a good quality. Harding preferred, therefore,
to manufacture pyroxyle, that is to say gun-cotton, a substance in which
cotton is not indispensable, as the elementary tissue of vegetables may
be used, and this is found in an almost pure state, not only in cotton,
but in the textile fiber of hemp and flax, in paper, the pith of the
elder, etc. Now, the elder abounded in the island towards the mouth of
Red Creek, and the colonists had already made coffee of the berries of
these shrubs, which belong to the family of the caprifoliaceae.

The only thing to be collected, therefore, was elder-pith, for as to the
other substance necessary for the manufacture of pyroxyle, it was only
fuming azotic acid. Now, Harding having sulphuric acid at his disposal,
had already been easily able to produce azotic acid by attacking the
saltpeter with which nature supplied him. He accordingly resolved to
manufacture and employ pyroxyle, although it has some inconveniences,
that is to say, a great inequality of effect, an excessive
inflammability, since it takes fire at one hundred and seventy
degrees instead of two hundred and forty, and lastly, an instantaneous
deflagration which might damage the firearms. On the othe
