the rate would proportionably fall, and as the produce would at the same time be diminished, its price would rise; he would be compensated for the tax, by charging it to the consumer, and no part would fall on rent; but this is impossible, at least with respect to some proportion of the capital, and consequently in that proportion the tax will be paid by the farmers during their leases, and by landlords at their expiration. This additional tax, as far as it fell unequally on manufacturers, would under such circumstances be added to the price of their goods; for there can be no reason why their profits should be reduced below the general rate of profits, when their capitals might be easily removed to agriculture.[26] CHAPTER XVII. ON SUDDEN CHANGES IN THE CHANNELS OF TRADE. A great manufacturing country is peculiarly exposed to temporary reverses and contingencies, produced by the removal of capital from one employment to another. The demands for the produce of agriculture are uniform, they are not under the influence of fashion, prejudice, or caprice. To sustain life, food is necessary, and the demand for food must continue in all ages, and in all countries. It is different with manufactures; the demand for any particular manufactured commodity, is subject not only to the wants, but to the tastes and caprice of the purchasers. A new tax too may destroy the comparative advantage which a country before possessed in the manufacture of a particular commodity; or the effects of war may so raise the freight and insurance on its conveyance, that it can no longer enter into competition with the home manufacture of the country to which it was before exported. In all such cases, considerable distress, and no doubt some loss, will be experienced by those who are engaged in the manufacture of such commodities; and it will be felt not only at the time of the change, but through the whole interval during which they are removing their capitals, and the labour which they can command, from one employment to another.
