Note 28 — ON STEPPES AND DESERTS.
Henry G. (Henry George) Bohn translation
p. 11.—“Preferring to keep within a cooler climate.”
Throughout the whole of Mexico and Peru we find the trace of human civilisation confined to the elevated table-lands. 131We saw the ruins of palaces and baths on the sides of the Andes, at an elevation of from 10,230 to 11,510 feet. None but northern tribes migrating from the north towards the equator could have remained from preference in such a climate.
