William Lewis Herndon, Lieutenant, U.S.N., Exploration of the Valley of the Amazon… (1853)
“ An hour’s travel brought us to the bottom of the hill, where we encountered the Chinchao valley coming down from the right. We crossed the stream that flowed through it, and travelled down the valley on its right bank, the road rising and falling on the sides of the hills. The character of the rock is a dark slate-stone, with occasional beds of gypsum. At seven miles from the tambo we passed the village of Chinchao, containing twelve houses and a church, with cotton, coffee, orange, and plantain trees scattered about the village. ”
