Energy, at the call of passion, they possess in abundance, but not that which is manifested in sustained and persevering labour: and as they seldom concern themselves enough about remote objects to establish good political institutions, the incentives to industry are further weakened by imperfect protection of its fruits. Successful production, like most other kinds of success, depends more on the qualities of the human agents, than on the circumstances in which they work: and it is difficulties, not facilities, that nourish bodily and mental energy. Accordingly the tribes of mankind who have overrun and conquered others, and compelled them to labour for their benefit, have been mostly reared amidst hardship. They have either been bred in the forests of northern climates, or the deficiency of natural hardships has been supplied, as among the Greeks and Romans, by the artificial ones of a rigid military discipline. From the time when the circumstances of modern society permitted the discontinuance of that discipline, the South has no longer produced conquering nations; military vigour, as well as speculative thought and industrial energy, have all had their principal seats in the less favoured North.

No one undergoes, without murmuring, a greater amount of occasional fatigue and hardship, or has his bodily powers, and such faculties of mind as he possesses, kept longer at their utmost stretch, than the North American Indian; yet his indolence is proverbial, whenever he has a brief respite from the pressure of present wants. Individuals, or nations, do not differ so much
