spruce logs reduced to the proper consistency by the mechanical and 

 the chemical or sulphite process, a plant where lead is economically 

 separated from its ore by electrolysis, a laboratory where vanilla and 

 other natural extracts are successfully prepared by synthetic chem-

Niagara Falls it is evident that that region is a very important electric 

 and electrochemical center and that it is destined to increase in im-
