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 on
which mas extended over a period of eight
years 1t Is difficult to realize how colossal
is the task involved in the preparation of a
work of this description. Thousands of pat
ents, American and foreign, have been di-
gested, industrial processes of every nature
have been examined and the latesti prove
ments therein noted. Engineering wofRs,
sci icntific discoveries, and tools OF every AFT
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 It ference and research. Add to this the
laDors of artist and engraver. and there is
little food for marvel that The work has cost
500 00D: that II treats of 30 600 subjects; con-
tains :. 400 epgravingsi and that its three voi
| uIles include 2 SJO pages. 1t is more all en-
