 it is likewise both limited and uncertain. It is limited by the local situation of the country, by the proximity or distance of its different provinces from the sea, by the number of its lakes and rivers, and by what may be called the fertility or barrenness of those seas, lakes, and rivers, as to this sort of rude produce. As population increases, as the annual produce of the land and labor of the country grows greater and greater, there come to be more buyers of fish, and those buyers, too, have a greater quantity and variety of other goods, or, what is the same thing, the price of a greater quantity and variety of other goods, to buy with. But it will generally be impossible to supply the great and extended market without employing a quantity of labor greater than in proportion to what had been requisite for supplying the narrow and confined one. 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 labor 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 extensive 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.

Though the success of a particular day's fishing may be a very uncertain matter, yet, the local situation of the country being supposed, the general efficacy of industry in bringing a certain quantity of fish to market, taking the course of a year, or of several years together, it may perhaps be thought, is certain enough; and it, no doubt, is so. As it depends more, however, upon the local
