In 1815 the peace with Great Britain, which gave such ecstasies of joy to the whole country, ruined Peter Cooper's business; as it was no longer possible to make cloth in the United States with profit. With three trades at his finger ends, he now tried a fourth, cabinet-making, in which he did not succeed. He moved out of town, and bought the stock of a grocer, whose store stood on the very site of the present Cooper Institute, at that time surrounded by fields and vacant lots. But even then he thought that, by the time he was ready to begin his evening school, that angle of land would probably be an excellent central spot on which to build it. He did very well with his grocery store; but it never would have enabled him to endow his Institute. One day when he had kept his grocery about a year, and used his new cradle at intervals in the rooms above, an old friend of his accosted him, as he stood at the door of the grocery. "I have been building," said his visitor, "a glue factory for my son; but I don't think that either he or I can make it pay. But you are the very man to do it." "I'll go and see it," said Peter Cooper. He got into his friend's wagon and they drove to the spot, which was near the corner of Madison Avenue and Twenty-ninth Street, almost on the very spot now occupied by an edifice of much note called "The Little Church Round the Corner." He liked the look of the new factory, and he saw no reason why the people of New York should send all the way to Russia for good glue. His friend asked two thousand dollars for the establishment as it stood, and Peter Cooper chanced to have that sum of money, and no more. He bought the factory on the spot, sold his grocery soon, and plunged into the manufacture of glue, of which he knew nothing except that Russian glue was very good and American very bad. Now he studied the composition of glue, and gradually learned the secret of making the best possible article which brought the highest price in the market. He worked for twenty years without a book-keeper, clerk, salesman, or agent. He rose with the dawn. When his men came at seven o'clock to work, they found the factory fires lighted, and it was the master who had lighted them. He watched closely and always the boiling of his glue, and at mid-day, when the critical operation was over, he drove into the city and went the round of his customers, selling them glue and isinglass, and passed the evening in posting his books and reading to his family.
