It may be interesting to know which is the largest city in China—the largest river in Africa—but it is more important to know about the industrial life of your country—because when most of you go out into the world you will become active figures in the making, buying and selling of things.
The Calumet Baking Powder factories, in Chicago and East St. Louis are the largest, most modern and sanitary plants of their kind on earth. More pounds of Calumet are sold than of any other brand of baking powder.
