Henry Rowe Schoolcraft,
Incentives to the Study of the Ancient Period of American History
“ Already science and exact investigation have accomplished the most auspicious and valuable results. The spirit of research has enabled us to unlock many secrets, which have remained sealed up for centuries. History has gleaned largely from the spirit of criticism; Ethnology has already reared a permanent monument to her own intellectual labors, and promises in its results, to unravel the intricate thread of ancient migration, and to untie the gordian knot of nations. ”
