“I do not speak with any fondness but the language of coolest history, when I say that Boston commands attention as the town which was appointed in the destiny of nations to lead the civilization of North America.”

“The Anglo-Saxon hive have extirpated Paganism from the greater part of the North American continent; but with it they have likewise extirpated the greater portion of the Red race. Civilization is gradually sweeping from the earth the lingering vestiges of Paganism, and at the same time the shrinking forms of its unhappy worshippers.”
