An oven he forthwith
determined to build. Having obtained the use of a corner of a factory
yard, his aged father, two of his brothers, his little son, and
himself sallied forth, with pickaxe and shovels, to begin the work:
and when they had done all that unskilled labor could effect towards
it, he induced a mason to complete it, and paid him in bricklayers'
aprons made of aqua-fortized India-rubber. This first oven was a
tantalizing failure. The heat was neither uniform nor controllable.
Some of the pieces of India-rubber would come out so perfectly "cured"
as to demonstrate the utility of his discovery; but others, prepared
in precisely the same manner, as far as he could discern, were
spoiled, either by blistering or charring. He was puzzled and
distressed beyond description; and no single voice consoled or
encouraged him. Out of the first piece of cloth which he succeeded in
vulcanizing he had a coat made for himself, which was not an
ornamental garment in its best estate; but, to prove to the
unbelievers that it would stand fire, he brought it so often in
contact with hot stoves, that at last it presented an exceedingly
dingy appearance.
