From the Scientific Americana
The completion of Knights American
Mechanical Dictionary" is an event in the
annals of literature IN this country, as II
marks the substantial completion of great
and elaborate undertaking, the labor on
which has extended over period OF eight
years II is difficult TO realize how colossal
is the task involved in the preparation OF
work nf this description. Thousands of pat
ents American and foreign, have been di-
gested, industrial processes OF every nature
have been examined and the latest prove
ments therein noted. Engineering works,
scientific discoveries, and tools OF every cl an
have been studied; and finally, all this i'm
mense collection, gathered from the whole
fieId of applied science, has been subjected
TO careful revision and condensation, and by
means Of ingeniously eontrived systems OF
indexing, rendered invaluable for purposes
of reference and research. Add 10 Ills the
IaDors of artist and engrayer. and there II
little food .or marvel that the work has cost
Sl0O 0OO: that IL treats of 20 o0O subjects; con-
tains 400 engravings; and that its three vol
umes irclude 800 pages. 1t is more an en-
cycl5poed la thar a dictionary; 1t is. in fact,a
mechanical and scientific library, carried up
TO the latost dates. A just estimate of the
com mpreheusfye nature Of the work, and its
importance TO inventors, engineers, and ar
tisans of every class and in all libraries, can

OF similar at1re, would be very great oil
account of IFS scope. It's great number of IL
lustrations. and the trustwOrthine-s OF its

by the fact that II 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 ofiIlustrations.
I engineers, mechanics and scientific men and
| students ofevery grade. will find here des-
| cribed ana illustrated more Of the instru-
| ments and machines peculiar to their pro
fession> than can be found in well furnished
| stores and manufactories, and they will also
find a constant supplementary course of in.
| struction so arranged as to be available for
| instant reference. The work consists of three
