 they can never be multiplied so as to hurt the public, though they may so as to hurt one another. The quantity of grocery goods, for example, which can be sold in a particular town, is limited by the demand of that town and its neighborhood. The capital, therefore, which can be employed in the grocery trade cannot exceed what is sufficient to purchase that quantity. If this capital is divided between two different grocers, their competition will tend to make both of them sell cheaper, than if it were in the hands of one only: and if it were divided among twenty, their competition would be just so much the greater, and the chance of their combining together, in order to raise the price, just so much the less. Their competition might perhaps ruin some of themselves; but to take care of this is the business of the parties concerned, and it may safely be trusted to their discretion. It can never hurt either the consumer or the producer; on the contrary, it must tend to make the retailers both sell cheaper and buy dearer, than if the whole trade was monopolized by one or two persons. Some of them, perhaps, may sometimes decoy a weak customer to buy what he has no occasion for. This evil, however, is of too little importance to deserve the public attention, nor would it necessarily be prevented by restricting their numbers. It is not the multitude of ale-houses, to give the most suspicious example, that occasions a general disposition to drunkenness among the common people; but that disposition arising from other causes necessarily gives employment to a multitude of alehouses.

The persons whose capitals are employed in any of those four ways are themselves productive laborers. Their labor, when properly directed, fixes and realizes itself in the subject or vendible commodity upon which it is bestowed, and
