DISCOVERERS OF THE ART OF IRON MANUFACTURE—BELCK. 5? 1 
given the metal by the inventors of ironworking migrated along with 
the metal to very many peoples, and philologians could therefore 
render valuable help in the search for the earliest iron industry. 
I can not close this discussion without referring with special satis- 
faction to von Luschan’s lucid and thorough treatise on African iron- 
working and the furnace apparatus and blowing apparatus employed 
by the Negroes.1_ A continued comparison of these utensils with 
those in use among peoples of other continents, will doubtless yield 
some important conclusions as to the age and peculiarity of iron- 
working among the Negroes as well as among other peoples. Simi- 
larly, we gratefully hail the investigations of Olshausen, Grosse, 
Busse, Krause, and Giebeler? of the quarrying of iron in prehistoric 
time, especially in Germany, which are valuable contributions to our 
question. Although I can not agree with these investigators on 
every point, I am glad to state that on the principal questions there 
is general agreement. In the near future I hope to present a separate 
study on the chemico-technological side of the quarrying of iron and 
of metals in general in antiquity.
