Without calling in question the policy, which dictated this alteration of the tax, I may be permitted to doubt whether it gave any great stimulus to accumulation. If the profits of the fisherman and others engaged in the trade, were doubled in consequence of more fish being consumed, capital and labour must have been withdrawn from other occupations to engage them in this particular trade. But in those occupations capital and labour were productive of profits, which must have been given up when they were withdrawn. The ability of the country to accumulate was only increased by the difference between the profits obtained in the business in which the capital was newly engaged, and those obtained in that from which it was withdrawn.
Whether taxes be taken from revenue or capital, they diminish the taxable commodities of the state. If I cease to expend 100l. on wine, because by paying a tax of that amount I have enabled Government to expend 100l. instead of expending it myself, one hundred pounds worth of goods are necessarily withdrawn from the list of taxable commodities. If the revenue of the individuals of a country be 10 millions, they will have at least 10 millions worth of taxable commodities. If by taxing some, one million be transferred to the disposal of Government,
