From the Scientific Americana
The completion of Knights american
Mechanical Dictionary" is an event in the
annals OF literature IN this country, as IL
marks the substantial completion of great
and elaborate undertaking, the labor on
which has extended over a period of eight
years. 1t is difficult to realize how colossal
is the task involved in the preparation of q
work nj this description. Thousands OF pat
ents, American and foreign, have been di-
gested, industrial processes of every nature
have been examined and the latestf prove
ments therein noted. Engineering works,
sci ciantific discoveries, and tools OF every craft
have been studied; and finally, all this I'M
mense collection, gathered from the whole
uoId of applied science, has been subjected
TO careful revision and condensation. and by
means Of ingeuiOusly contrived systems of
| indexing, rendered invaluable for purposes
of rt ference and research. Add to this the
| laoors of artist and engraver. and there Is
little food for marvel that the work has cost
500 900: that IT treats of 1000 subjects; con-
tains z 400 eDgravings; and that its three vol
umes include $40 pages. 1t is more au en-
cyclopoedia than a dictionary; il is, in fact, a
mechanical and scientific library, carried up
| to the latest dates. A just estimate of the
| comprehensive nature of the work, and its
| importance TO inventors, engineers, and ar
| tisans of every class and in all libraries ca U
| only be gained by careful examination ofthe
| voIumes themselves.
| The scope ofthis work concernsA gricuitural
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, AR. and
Gas Engines and other Motors; Lighting,
| Heating, Drying. and Ventilating; Fine Arts;
| Photographic, Electric, Telegraphic, Optical,
| Theological, Calculating, urgical. and Den
tai Instruments, etc.
Its value.even IL there were in print Others
tOf q similar mai fuTe, would be very great Oh
| account of its scope. Its great number OF IL
ilustrattons, and the trustworthfness OF ttt
| author; but at present its value Is enhanced
by the fact that il has. properly speaking, no
| competitor. There is published no book OF
similar intent which is at once SO large, SO
| well illustrated, so closely brought down 10
the present time, and SO full ofillustrations
