The completion OF Knights American
Mechanical Dictionary" is an event in the
annals CT literature IN this country, as IL
marks the substantial completion of a 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
work al this description. Thousands of pat
sents, American and foreign, have been di-
gested, industrial processes of every nature
have been examined and the latest il prove
ments therein noted. Engineering works,
scientific discoveries and tools of every craft
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
laDors of artist and engraver. and there is
little food for marvel that the work has cost
500 000: that ii treats of 20 600 subjects; con-
tains 400 engravings; and that its three vol
umes include 800 pages IL is more an en-
cyclopOedia thar a dicif0nary; ii is. in fact a
mechanical and scientific library, carried up
to the latest dates. A just estimate of the
i'm mportance to inventors, engineers, and ar
tisans of every class and In all libraries, can
only be gained by careful examination ofthe
voIumes themselves.
The scope ofthis work concerns A AgricuItural
Machinery, Wood, Metal, Glass, Stone Clay

Itsvalue even IL there were In print others
| OF q 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

competitor. There is published no book OF
similar intent which is at once SO large, SO
well illustrated 80 closely brought down 10
l the present time, and SO full ofillustratioDs.
| Dentists. surgeons, philosophers. chemists.
engineers. s.mechanics, and scientific men and
students ofevery grade. will find here des-
| cribed and illustrated more Of the instru-
ments and machines peculiar to their pro
| fession than can be found In well furnished
| stores and manufactures, 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
| handsome octave volumes and will be found
