The labouring man, who is using his limbs the greater part of his life in lifting heavy weights, &c. sweats them with the weight of clothes which he has on him, which softens the integuments and the flesh, leaving the muscles to stand out in more conspicuous relief when they are exposed; whilst the Indian, who exercises his limbs for the most of his life, denuded and exposed to the air, gets over his muscles a thicker and more compact layer of integuments which hide them from the view, leaving the casual spectator, who sees them only at rest, to suppose them too decidedly inferior to those which are found amongst people of his own colour. Of muscular strength in the legs, I have met many of the most extraordinary instances in the Indian country, that ever I have seen in my life; and I have watched and studied such for hours together, with utter surprise and admiration, in the violent exertions of their dances, where they leap and jump with every nerve strung, and every muscle swelled, till their legs will often look like a bundle of ropes, rather than a mass of human flesh. And from all that I have seen, I am inclined to say, that whatever differences there may be between the North American Indians and their civilized neighbours in the above respects, they are decidedly the results of different habits of life and modes of education rather than of any difference in constitution. And I would also venture the assertion, that he who would see the Indian in a condition to judge of his muscles, must see him in motion; and he who would get a perfect study for an Hercules or an Atlas, should take a stone-mason for the upper part of his figure, and a Camanchee or a Blackfoot Indian from the waist downwards to the feet.
