Thej found placed at nearly equal distances apart, sta 

 tions consisting of dwelling-houses built of well-cut stone 

 These stations were a kind of caravanserai, and were 

 called Tambos, and Inca-houses. Some were surrounded 

 by a kind of fortification ; others were constructed for 

 baths with arrangements for conducting hot water. The 

 largest of them were designed for the use of the family

There were two great artificial Peruvian paved roads 

 or systems of roads, covered with flat stones, or some-

 the wide and arid plain between the Pacific Ocean and 

 the chain of the Andes, and the other over the ridges of
