At Valparaiso Darwin found an old school-mate, 

 with whom he took up his residence, making daily 

 trips into the surrounding country, ever showing that 

 care and earnest research that forms so prominent a 

 feature in all his work. One of the rides which he 

 took along the base of the Andes was to the hacienda

 was almost entirely composed of shells, while the

 minute portions of organic matter. In this deposit 

 the young naturalist saw further evidence of the vast 

 upheaval which had taken place here, and the pres-

 above the present ocean level was viewed by him 

 with no little interest and wonder. 



Many mines were visited in the neighbouring 

 country, there being at that time a mining craze for 

 gold and copper. The life of the miners was one to

 continuing until dark, with scarcely any intermission. 

 They received for their labour five dollars per month, 

 and food which consisted of the following : For

 an earthquake stopped the flow, which did not re-
