If it is a commodity of home growth or manufacture, less labor comes to be employed in raising and producing it. If it is a foreign commodity of which the tax increases in this manner the price, the commodities of the same kind which are made at home may thereby, indeed, gain some advantage in the home market, and a greater quantity of domestic industry may thereby be turned toward preparing them. But though this rise of price in a foreign commodity may encourage domestic industry in one particular branch, it necessarily discourages that industry in almost every other. The dearer the Birmingham manufacturer buys his foreign wine, the cheaper he necessarily sells that part of his hardware with which, or, what comes to the same thing, with the price of which he buys it. That part of his hardware, therefore, becomes of less value to him, and he has less encouragement to work at it. The dearer the consumers in one country pay for the surplus produce of another, the cheaper they necessarily sell that part of their own surplus produce with which, or, what comes to the same thing, with the price of which they buy it. That part of their own surplus produce becomes of less value to them, and they have less encouragement to increase its quantity. All taxes upon consumable commodities, therefore, tend to reduce the quantity of productive labor below what it otherwise would be, either in preparing the commodities taxed, if
