The completion of Knights American
Mechanics Dictionary" is an event in the
annals OF literature m this country as il
marks The substantial completion OF a great
and elaborate undertaking, the labor on
which las extended over a period of eight
years. II is difficult to realize how colossal
Is the task involved in the preparation of a
work nf this description. Thousands of pat
ents, American and foreign, have been di-
ges5ed, industrial processes of every nature
have been examined and the latest ia prove
ments therein noted. Engineering works,
sciSntific discoveries, and tools OF every crafi
have been studied; and finally, all this i'm
mense collection, gathered from the whole
field OF applied science. has been subjected
TO careful revision and condensation. and by
means OF ingeniously contrived systems OF
indexing, rendered invaluable for purposes
OF reference and research. Add TO this the
laOors of artist and engraver. and there il
little food for marvel that the work has cost
slG0. 900: that IL treats of 900 subjects; con-
tains 400 engravings; and that its three vol
uInes include 2 500 pages. 1t is more an en-
cycloppdia than Il dictionary; it is, in fact, a
mechanical and scientific library, carried up
to the latest dates. A Just estimate of the
importance to inventors, engineers, and ar
tisans of every class and in. all libraries, can
only be gained Dy Careful examination oil the
voIumes themselves.
The scope oithis work concerns gricultural
Machinery, Wood, Metal, Glass, Stone. Clay,
Cement, and Leather Working; Mining Hy-
draulic, Railway, Marine, and Military En-
gineering; Working in Cotton, Wool, Silk,
Flax, Hemp, and Paper; Steam, AIR. and
Gas Engines, and other Motors: Lighting

Photograph, Electric, Telegraphic, Optical,
Horological, Calculating, urgical, and Den
tai Instruments. etc. p ..---..
Itsvalue.eyen If there were in print Others
OF a similar nature, would be very great on
account of its scope. its great number of H.
lustrations, and the trustworthiness of its
author, but at present its value is enhanced
by the fact that IL has. properly speaking, no
competition. There is published no BOOK of
similar intent which is at once so large, so
well Illustrated, SO closely brought down 10
the present lime. and so full ofiliustfationS.
