A market which, from requiring only one thousand, comes to

require annually ten thousand ton of fish, can seldom be

supplied, without employing more than ten times the quantity of

labour which had before been sufficient to supply it. The fish

must generally be sought for at a greater distance, larger

vessels must be employed, and more expensive machinery of every

kind made use of. The real price of this commodity, therefore,

naturally rises in the progress of improvement. It has

accordingly done so, I believe, more or less in every country.
