The Thames salmon used to be reckoned the most recherché; but since so
many steam-boats have been introduced upon the surface of that noble
river, and the tunnel has been built, introducing their greatest
enemies, human beings, both above and below their liquid habitation,
they have fled to the ocean for protection, and are now no longer
discernible from their once commoner brethren. But the Severn salmon is
now esteemed the best; the crimped is in the highest favour with the
gourmets. It would be useless to make any observations about this fish,
as it is well known to range as one of the highest order.
