The Memoirs of Napoleon, V4, 1800

When the First Consul contemplated the building of the Pont des Arts we had a long conversation on the subject. I observed that it would be much better to build the bridge of stone. The first object of monuments of this kind, said I, is public utility. They require solidity of appearance, and their principal merit is duration. I cannot conceive, General, why, in a country where there is abundance of fine stone of every quality, the use of iron should be preferred.
