From the Scientific Americana
The completion OF Knights American
Mechanical Dictionary" is an event in the
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
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 il prove
scientific discoveries, and tools OF every craft
have been studied; and finally, all this inn
mense collection, gathered from the whole
field of applied science, has been subjected
TO careful revision and condensation, and by
means Of ingeniously contriYed systems OF
indexing, rendered Invaluable for purposes
of reference and research. Add to this the
lapors of artist and engraver. and there is
little food for marvel that the work has cost
500 600: that IT treats of 20 900 subjects; con-
tains 1900 engravings; and that its three vol
umes include 2 500 pages. 1t is more an en-
cyclopoedia thar a dictionary; 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
only be gained by careful examination ofthe
voIumes themselves
