During this time Mr. Cooper had learned to know a beautiful girl named Sarah Bedell. This girl became his wife.
They moved to New York.
Here Mr. Cooper had a grocery-store.
A friend advised him to buy a glue factory which was for sale.
He knew nothing of the business, but he thought he could learn it.
He soon made not only the best glue, but the cheapest in the country.
For thirty years he carried on this business almost alone, with no salesman and no book-keeper.
He rose every morning at daylight, kindled his factory fires, and worked all the forenoon making glue.
In the afternoon he sold it.
In the evenings he kept his accounts, wrote his letters, and read with his wife and children.
