For the present I shall only remark that so long as the quantity of a natural agent is practically unlimited,it cannot,unless susceptible of artificial monopoly,bear any value in the market,since no one will give anything for what can be obtained gratis.

• 这里我仅仅指出，只要某种自然要素的数量实际上是无限的，则除非能被人垄断，否则它在市场上就不会有任何价值，因为没有人会用东西换取可以无偿得到的东西。
