is the task involved in the preparation of

euts, American and foreign, have been di-
gested, industrial processes of every nature
have been examined and the latest iiu 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
ueId 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 engrayer. and there Is
| little food for marvel that the work has cost
500 900: that it treats OF 20 900 SUBJECTS con-
| tains 400 engravings; and that its three vol
| umes include 2.SO0 pages. 1t is more an en-
| cyclopOedia thar dictionary; IL is, in fact, "A
