constructed for baths with arrangements for conducting hot water; the larger were designed for the use of the family of the Monarch himself. I had previously seen, measured, and drawn with care, buildings of the same kind in a good state of preservation at the foot of the volcano of Cotopaxi, near Callo. Pedro de Cieça, writing in the 16th century, called them "Aposentos de Mulalo."[3] In the pass between Alausi and Loxa, called the Paramo del Assuay,—(a much frequented route across the Ladera de Cadlud, 14568 French or 15526 English feet above the level of the sea, or almost equal to the height of Mont Blanc),—as we were leading our heavily laden mules with great difficulty through the marshy ground on the elevated plain del Pullal, our eyes meanwhile were continually dwelling on the grand remains of the Inca's road, which with a breadth of twenty-one English feet ran by our side for above a German mile. It had a deep under-structure, and was paved with well-cut blocks of blackish trap-porphyry. Nothing that I had seen of the remains of Roman roads in Italy, in the South of France, and in Spain, was more imposing than these works of the ancient Peruvians, which are moreover situated, according to my barometric measurements, at an elevation of 12440 (13258 English) feet above the sea, or more than a thousand feet higher than the summit of the Peak of Teneriffe.
