[Theodore Roosevelt] was a naturalist on the broadest grounds, uniting much technical knowledge with knowledge of the daily lives and habits of all forms of wild life.

Science has done more for the development of western civilization in one hundred years than Christianity did in eighteen hundred years.

I do not think I exaggerate the importance or the charms of pedestrianism, or our need as a people to cultivate the art. I think it would tend to soften the national manners, to teach us the meaning of leisure, to acquaint us with the charms of the open air, to strengthen and foster the tie between the race and the land. No one else looks out upon the world so kindly and charitably as the pedestrian; no one else gives and takes so much from the country he passes through.
