in the character which is
required in the laborers, in the different cases. A cotton plantation
in the south can be cultivated by slaves. A grain farm in the middle
states can be worked by hired laborers; but a northern grass farm,
with all its oxen, cows, sheep, poultry, and horses, can only be
successfully managed by the work of the owner."

"Is that the reason why they have slaves at the south?" asked Marco.

"It is a reason why slaves can be profitable at the south. In
cultivating cotton or sugar, a vast proportion of all the work done
in the year is the same. Almost the whole consists of a few simple
processes, such as planting, hoeing, picking cotton, &c., and this is
to be performed on smooth, even land, where set tasks can be easily
assigned. But the work on a grass farm is endlessly varied. It would
not be possible to divide it into set tasks. And then it is of such a
nature, that it could not possibly be performed successfully by the
mere labor of the hands. The _mind_ must be employed upon it. For
instance, even in getting in hay, in the summer season, the farmer has
to exercise all his judgment and discretion to avoid getting it wet by
the summer showers, and yet to secure it in good time, and with proper
dispatch. A cotton planter may hire an overseer to see to the getting
in of his cotton, and he can easily tell by the result, whether he
has been faithful or not. But hay can not be got in well, without the
activity, and energy, and good judgment, which can come only from the
presence and immediate supervision of an owner. This produces vast
differences in the nature of the business, and in the whole state of
society in the two regions."

"What are the differences?" asked Marco.

"Why, in the first place," said Forester, "the fact that cotton and
sugar can be cultivated by hired overseers, with slaves to do the
work, enables rich men to carry on great plantations without laboring
themselves. But a great grass farm could not be managed so. A man may
have one thousand acres for his plantation at the south, and with a
good overseer and good hands, it will all go on very well, so far as
his profit is concerned. They will produce a great amount of cotton,
which may be sent to market and sold, and the planter realize the
money, so as to make a large profit after paying all his expenses. But
if a man were to buy a thousand acres of grass land, and employ an
overseer and slaves to cultivate it, every thing woul
