Book The Second: Riches Chapter 8 The Dowager Mrs Gowan is reminded that It Never Does

While the waters of Venice and the ruins of Rome were sunning themselves
for the pleasure of the Dorrit family, and were daily being sketched
out of all earthly proportion, lineament, and likeness, by travelling
pencils innumerable, the firm of Doyce and Clennam hammered away in
Bleeding Heart Yard, and the vigorous clink of iron upon iron was heard
there through the working hours.

The younger partner had, by this time, brought the business into sound
trim; and the elder, left free to follow his own ingenious devices, had
done much to enhance the character of the factory.

As an ingenious man, he had necessarily to encounter
every discouragement that the ruling
powers for a length of time had been able by any means to put in the way
of this class of culprits; but that was only reasonable self-defence in
the powers, since How to do it must obviously be regarded as the natural
and mortal enemy of How not to do it.

In this was to be found the basis
of the wise system, by tooth and nail upheld by the Circumlocution
Office, of warning every ingenious British subject to be ingenious
at his peril: of harassing him, obstructing him, inviting robbers (by
making his remedy uncertain, and expensive) to plunder him, and at the
best of confiscating his property after a short term of enjoyment, as
though invention were on a par with felony.

The system had uniformly
found great favour with the Barnacles, and that was only reasonable,
too; for one who worthily invents must be in earnest, and the Barnacles
abhorred and dreaded nothing half so much. That again was very
reasonable; since in a country suffering under the affliction of a great
amount of earnestness, there might, in an exceeding short space of time,
be not a single Barnacle left sticking to a post.

Daniel Doyce faced his condition with its pains and penalties attached
to it, and soberly worked on for the work's sake. Clennam cheering him
with a hearty co-operation, was a moral support to him, besides doing
good service in his business relation. The concern prospered, and the
partners were fast friends.
