It is a losing trade, it is said, which a workman carries on with the alehouse; and the trade which a manufacturing nation would naturally carry on with a wine country may be considered as a trade of the same nature. I answer, that the trade with the alehouse is not necessarily a losing trade. In its own nature it is just as advantageous as any other, though perhaps somewhat more liable to be abused. The employment of a brewer, and even that of a retailer of fermented liquors, are as necessary divisions of labour as any other. It will generally be more advantageous for a workman to buy of the brewer the quantity he has occasion for than to brew it himself, and if he is a poor workman, it will generally be more advantageous for him to buy it by little and little of the retailer than a large quantity of the brewer.
