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
ana elaborate undertaking, the labor on
which has extended over period of eight
years. 1t 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-
gested, industrial processes of every nature
have been examined and the latest Ia 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
10 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
siOO 0JO: that it treats of 1900 subjects; con-
tains :, 400 engravings; and that its three vol
umes include SO pages. 1t is more an en-
cyclopoedia than dictionary; it is. in faet-a
mechanical and scientific library, carried up
to the latest dates A just estimate of the
comprehensive nature of the work, and its
