From the Scientific Americana
The completion of Knights american
Mechanical Dictionary" is an event in the
annals OF literature N this country. as II
marks the substantial completion of great
and elaborate undertaking, the labor on
which has extended over a period of eight
wears IL 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 d.
gested Industrial processes of every nature
iSave been examined and the latesti 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 contrtved systems OF
ipdexing, rendered invaluable for purposes
of reference and research. Add to this the
lauors of artist and engraver. and there Is
little food for marvel that the work has cost
500 OOO that IL treats of 20,000 subjects; con-
tains 400 engravings; and that lis three vol
umes include $40 pages. IL is more an en-
cyclopoedia thar diciionary; 1t is. In fact,a
mechanical and scientific library, carried up
to the latest dates. Just estimate OF the
comprehensive nature of the work, and lis
importance to inventors. engineers, ana ar
tisans of every class and in all libraries, can
only be gained by careful examination OF The
yoiumes themselves.
The scope ofthis work concerns gricultural
Machinery, WOOO. metal, ,OlaSS, stone. clay,
