Here then is the mutual commerce of good offices in a manner lost among mankind, and every one reduc'd to his own skill and industry for his well-being and subsistence. The invention of the law of nature, concerning the stability of possession, has already render'd men tolerable to each other; that of the transference of property and possession by consent has begun to render them mutually advantageous: But still these laws of nature, however strictly observ'd, are not sufficient to render them so serviceable to each other, as by nature they are fitted to become. Tho' possession be stable, men may often reap but small advantage from it, while they are possess'd of a greater quantity of any species of goods than they have occasion for, and at the same time suffer by the want of others. The transference of property, which is the proper remedy for this inconvenience, cannot remedy it entirely; because it can only take place with regard to such objects as are present and individual, but not to such as are absent or general. One cannot transfer the property of a particular house, twenty leagues distant; because the consent cannot be attended with delivery, which is a requisite circumstance. Neither can one transfer the property of ten bushels of corn, or five hogsheads of wine, by the mere expression and consent; because these are only general terms, and have no direct relation to any particular heap of corn, or barrels of wine.

I have no kindness for you, and know you have as little for me. I will not, therefore, take any pains upon your account; and should I labour with you upon my own account, in expectation of a return, I know I shou'd be disappointed, and that I shou'd in vain depend upon
