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 OD
which has extended over a period OF eight
years. 1t Is difficult TO realize how colossal
Is the task involved In the preparation of a
work n1this description. Thousands OF pat.
ents, 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 10 this the
laDors Of artist and engraver. and there IL
little food for marvel that the work has cost
500 .0OG: that it treats OF 10000 subjects; con
tains 400 engravings; and that lis three vol
umes Include 800 pages. 1t is more an en-
cycloposdia Thar dcIi i0nary; ii 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, can
voIumes themselves.
