One hundred years ago neither dwelling, church, nor city greeted the eye that gazed over the broad expanse of the unfilled prairies. Here were no accumulations of wealth, no signs of human habitation, except a few Indians wandering in groups or assembled in their wigwam villages. The evidences of art and industry were meagre, and of accumulated knowledge small, because the natives were still the children of nature and had gone but a little way in the mastery of physical forces or in the accumulation of knowledge. The relative difference in their condition and that of those that followed them is the contrast between barbarism and civilization.
