The completion OF Knights American
| Mocha nical dictionary" is an event in the
Annals of Literature n 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 prepa ration of a
work nj this description. Thousands of pat
| ents, American and foreign, have been di-
gested, industrial processes OF every nature
| have been examined and the latest iiI prove
| ments therein noted. Engineering works,
| scientific discoveries, and tools OF every craft
have been studied; and finally, all Ibis 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
laoors OF artist and engraver. and there is
little food for marvel that the work has cos:
slcJ e0a: that II treats OF - coo subjects; con-
tains I, 800 engravings; and that lis three vol
umes Include so pages 1t is more an en-
cyclopadia thar dictionary; it is. in fact a
mechanical nd scientific library, carried up
TO the latest daies- A just estimate of the
C sIn pfehtnS We nature of the woIk and its
mpor' ance to inventors, engineers, and ar
iiSins OF every class and In all Libraries, can
Only be gained by careful examination ofIhe
volumes themselves.

lustrations, and the trustworthiness OF its
