IL reply that Mr.. W. R. Johnson makes to the
caution, which we have published against his de-
ceptions, is, that the model we exhibit is not made
a scale for the proposed for the government.
Does he suppose that people are such consummate
fools not to know that models of such large
structures cannot be made 10 scale and be ioorking
models' II made to a scale, the frame would not
be larger than knitting needles, the machinery
would be SO small scarcely to be visible, and
would be wholly incapable on that account Of work
ing, and the lifting power would be too rifing TO
raise even the model of a vessel made in the slight.
est manner possible The sole object Of model is
to show the principle of the structure and how it
,oork, in practice. The proportions in the structure
itself may be varied to suit circumstances


The tin carioaure model of the sectional dock
made by some tinker, and shown by Johnson Il
Co, may be, for ought we know, in due proportion
in length, breadth, &c; but what we complain Of
is, that it does not exhibit the method of porking
the dock the uniform motion which is given to its
balancing sde-hoas, and the absolute and complete
control exercised thereby over the raising and sink
ing Of the structure.


In regard to the charge Of our unwillingness TO
have the models Of the two docks shown side by
side it is enough to say that we have no objection
to il if a proper toorking model Of our plan were
presented; and that the docks themselves exhibited
side by side in New York; and we have brought
the certificate of ALL The shpbuiders there without
exception, and all the principal shipotoners, that ours
is the best plan Of dock and commands the business,
though the price Of docking in the balance dock is
90 per cent less than in ours. This is surely
better test Of the merits Of the two plans than Mr.
Johnson's lectures his rude tinker models,
