"Well," said he, smiling, "of course that is what they _are_ for. Where there are salmon, there are likely to be salmon-nets, Tay or Thames; but of course they are not always in use; we don't want salmon _every_ day of the season." I was going to say, "But is this the Thames?" but held my peace in my wonder, and turned my bewildered eyes eastward to look at the bridge again, and thence to the shores of the London river; and surely there was enough to astonish me. For though there was a bridge across the stream and houses on its banks, how all was changed from last night! The soap- works with their smoke-vomiting chimneys were gone; the engineer's works gone; the lead-works gone; and no sound of rivetting and hammering came down the west wind from Thorneycroft's. Then the bridge! I had perhaps dreamed of such a bridge, but never seen such an one out of an illuminated manuscript; for not even the Ponte Vecchio at Florence came anywhere near it. It was of stone arches, splendidly solid, and as graceful as they were strong; high enough also to let ordinary river traffic through easily. Over the parapet showed quaint and fanciful little buildings, which I supposed to be booths or shops, beset with painted and gilded vanes and spirelets. The stone was a little weathered, but showed no marks of the grimy sootiness which I was used to on every London building more than a year old. In short, to me a wonder of a bridge. The sculler noted my eager astonished look, and said, as if in answer to my thoughts-- "Yes, it _is_ a pretty bridge, isn't it? Even the up-stream bridges, which are so much smaller, are scarcely daintier, and the down-stream ones are scarcely more dignified and stately." I found myself saying, almost against my will, "How old is it?" "Oh, not very old," he said; "it was built or at least opened, in 2003. There used to be a rather plain timber bridge before then."
