I observed to him, that less was known of this continent than of the

parts of the globe; but that all the efforts yet made, had still left
a large portion almost entirely unknown. I asked if he did not think it

"No, no," said he; "the benefits of civilization could not have been so

existed. The intense heat of a climate, lying on each side of the Line,
at once disinclines men to exertion, and renders it unnecessary. Vegetable
diet is more suited to them than animal, which favours a denser population.
Talent is elicited by the efforts required to overcome difficulties
and hardships; and their natural birth-place is a country of frost and
