Thus the enormous quantity of cotton which grows every summer in the southern states, is packed in bags, very tight, and is hauled to the rivers and creeks, and there it is put into steamboats and sent to the great seaports, and at the seaports it is put into ships, which carry it to England or to the northern states, to be manufactured; and it is so valuable, that it will bring a price sufficient to pay all the persons that have been employed in raising it, or in transporting it.

But the grass that grows in the northern countries can not be transported.

The mills for manufacturing cotton may be in one country, and the cotton be raised in another, and then, after the cotton is gathered, it may be packed and sent thousands of miles to be manufactured.

But the sheep and oxen which are to eat the hay, can not be kept in one country, while the grass which they feed upon grows in another.

The animals must live, in general, on the very farm which the grass grows upon.
