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.

That is because Calumet is the best purest, most dependable baking powder made; makes the finest, most wholesome, tasty pies, cakes, biscuits, doughnuts, etc.

You will find the same rule applies to everything you do in life. If you do a thing better than any one else—your services will always be in demand and you will surely be a leader in your line of work. Calumet Baking Powder is sold at a moderate price—has more than the usual leavening strength—and never fails.
