He had brought with him from America, as we have seen, a model of a bridge of his own construction and invention, which model had been adopted in England for building bridges under his own direction. He employed part of his time, while at our house, in bringing this model to high perfection, and this accomplished to his wishes. He afterwards, and according the model, made a bridge of lead, which he accomplished b/ moulding different blocks of lead, which, when joined together, made the form that he required. This was most pleasant amusement for him. Though he fully relied on the strength of his new bridge, and would produce arguments enough in proof of its infallible strength, he often demonstrated the proof by blows of the sledge-hammer, not leaving anyone in doubt on the subject. One night he took off the scaffold of his bridge and seeing that it stood firm under the repeated strokes of hammer, he was so ravished that an enjoyment so great was not to be sufficiently felt if confined to his own bosom. He was not satisfied without admirers of his success. One night we had just gone to bed, and were surprised at hearing repeated strokes of the hammer. Paine went into Mr. Bonneville's room and besought him to go and see his bridge: come and look, said he, it bears all my blows and stands like a rock. Mr. Bonneville arose, as well to please himself by seeing a happy man as to please him by looking at his bridge. Nothing would do, unless I saw the sight as well as Mr. Bonneville. After much exultation: "nothing, in the world," said he, "is so fine as my bridge"; and, seeing me standing by without uttering a word, he added, "except a woman!" which happy compliment to the sex he seemed to think, a full compensation for the trouble caused by this nocturnal visit to the bridge. A machine for planing boards was his next invention, which machine he had executed partly by one blacksmith and partly by another. The machine being put together by him, he placed it on the floor, and with it planed boards to any number that he required, to make some models of wheels. Mr. Bonneville has two of these wheels now. There is a specification of the wheels, given by Mr. Paine himself. This specification, together with a drawing of the model, made by Mr. Fulton, were deposited at Washington, in February 1811; and the other documents necessary to obtain a patent as an invention of Thomas Paine, for the benefit of Madam Bonneville. To be presented to the Directory of France, a memorial on the progress and construction of iron bridges. On this subject the two pieces here subjoined will throw sufficient light.
