Near the large vat, into which Forester had descended, there was a
cistern of cold water. Henry seized a bucket, which was floating in the
cistern, filled it with water, and emptied the water into the vat,
dashing it against the sides, to disperse the water, and to displace the
mephitic air[4], He called to the people, who surrounded him, for
assistance; the water expelled the air; and, when it was safe to descend,
Henry instantly went down the ladder himself, and fastened the cord round
Forester, who was quite helpless.

[Footnote 4: Carbonic acid gas.]

"Draw him up!" said Henry, They drew him up. Henry fastened another cord
round the body of the other man, who lay at the bottom of the vessel, and
he was taken up in the same manner. Forester soon returned to his senses,
when he was carried into the air; it was with more difficulty that the
other man, whose animation had been longer suspended, was recovered; at
length, however, by proper application, his lungs played freely, he
stretched himself, looked round upon the people who were about him with
an air of astonishment, and was some time before he could recollect what
had happened to him. Forester, as soon as he had recovered the use of his
understanding, was in extreme anxiety to know whether the poor man, who
went down for his key, had been saved. His gratitude to Henry, when he
heard all that had passed, was expressed in the most enthusiastic manner.

"I acted like a madman, and you like a man of sense," said Forester. "You
always know how to do good: I do mischief, whenever I attempt to do good.
But now, don't expect, Henry, that I should give up any of my opinions to
you, because you have saved my life. I shall always argue with you just
as I did before. Remember, I despise _address_, I don't yield a single
point to you. Gratitude shall never make me a sycophant."
