CEMENT IS USED BUT NOT CONSUMED 
There is an old saying that you cannot eat your cake 
and have it too, and this is true of most things. Practically 
all commodities are consumed in use. Food is consumed. 
Clothing is consumed. 
But there is a product used but not consumed. Cement 
is used in making concrete, and concrete is permanent. It 
grows stronger with age. It cannot rust, rot, decay or burn. 
It endures. 
Concrete highways connect city and country. Concrete 
forms the base of well-paved streets and alleys. A gridiron 
of hundreds of thousands of miles of concrete sidewalks in 
the United States makes walking easy. Railroads are large 
users of concrete. Modern buildings are of reinforced con- 
crete. Concrete goes into many farm structures. Almost 
everything from chicken coops to skyscrapers rests on a 
concrete foundation. 
Up to November 1, 1921, the Universal Portland 
Cement Co. has shipped a total of over 500 million sacks of 
portland cement. This would fill over 700 thousand box 
cars, making a train 5,000 miles long and requiring about 
18,000 locomotives to move it. This is enough to build a 
system of concrete roads radiating from Pittsburgh to the 
capital of every state in the union. 
Practically all this Universal cement—-500 million sacks— 
still serves a useful purpose. It has not been consumed but 
has been transformed into houses, industrial buildings, im- 
proved highways, water-power developments and other valu- 
able improvements that form additions to the permanent, 
taxable wealth of the country as well as tools for production 
of additional wealth. 
Universal cement is used but not consumed.
