He still had his tract of Baltimore land upon his hands, which the check to the prosperity of the city rendered for the time almost valueless; so he determined to build ironworks upon it, and a rolling-mill. In his zeal to acquire knowledge at first hand, he had a narrow escape from destruction in Baltimore. "In my efforts to make iron," he said, "I had to begin by burning the wood growing upon the spot into charcoal, and in order to do that, I erected large kilns, twenty-five feet in diameter, twelve feet high, circular in form, hooped around with iron at the top, arched over so as to make a tight place in which to put the wood, with single bricks left out in different places in order to smother the fire out when the wood was sufficiently burned. After having burned the coal in one of these kilns perfectly, and believing the fire entirely smothered out, we attempted to take the coal out of the kiln; but when we had got it about half-way out, the coal itself took fire, and the men, after carrying water some time to extinguish it, gave up in despair. I then went myself to the door of the kiln to see if anything more could be done, and just as I entered the door the gas itself took fire and enveloped me in a sheet of flame. I had to run some ten feet to get out, and in doing so my eyebrows and whiskers were burned, and my fur hat was scorched down to the body of the fur. How I escaped I know not. I seemed to be literally blown out by the explosion, and I narrowly escaped with my life." The ironworks were finally removed to Trenton, New Jersey, where to this day, under the vigorous management of Mr. Hewitt and his partners, they are very successful. During these active years Peter Cooper never for a moment lost sight of the great object of his life. We have a new proof of this, if proof were needed, in the Autobiography recently published of the eloquent Orville Dewey, pastor of the Unitarian Church of the Messiah, which Peter Cooper attended for many years. "There were two men," says Dr. Dewey, "who came to our church whose coming seemed to be by chance, but was of great interest to me, for I valued them greatly. They were Peter Cooper and Joseph Curtis.[2] Neither of them then belonged to any religious society, or regularly attended any church. They happened to be walking down Broadway one Sunday evening, as the congregation were entering Stuyvesant Hall, where we then temporarily worshiped, and they said:-- "'Let us go in here and see what _this_ is.' "When they came out, as they both told me, they said to one another:-- "'This is the place for _us_!'
