told that the glory has departed
from the very best of its localities, and given them up to various
degrees of squalor. Vice, poverty, and misery seem to gravitate
naturally southward in London. I don't know why, but they do. Well,
here is the door of my humble den."

As he spoke he put the key in the lock, and opened the door, bidding
his companion enter as he did so.

Arnold's anxiety was soon relieved by finding the precious model
untouched in its resting-place, and it was at once brought out.
Colston was delighted beyond his powers of expression with the
marvellous ingenuity with which the miracle of mechanical skill was
contrived and put together; and when Arnold, after showing and
explaining to him all the various parts of the mechanism and the
external structure, at length set the engine working, and the

could conquer the world in a month!"

"Yes, that would not be a very difficult task, seeing that neither an
army nor a fleet could exist for twelve hours with two or three of

"What is that for? A sovereign will be quite enough to get me out of
my present scrape, and then if we come to any terms to-night it will
be time enough to talk about payment."

"The Brotherhood does not do business in that way," was the reply.
"At present your only connection with it is a commercial one, and ten
pounds is a very moderate fee for the privilege of inspecting such an
invention as this. Anyhow, that is what I am ordered to hand over to
you in payment for your trouble now and to-night, so you must accept
it as it is given--as a matter of business."

"Very well," said Arnold, closing and locking the chest as he spoke,
"if you think it worth ten pounds, the money will not come amiss to
me. Now, if you wi
