 of the geology of sixteen counties. 



Chapter 1. by Mr. E. B. Andrews, gives an account of the Surface- 

 geology of South-eastern Ohio ; and the same observer contributes the 

 following six chapters on the local geology of as many counties. 

 Finally, Prof. Edward Orton contributes three chapters on the geo-

 About 100 miles inland from the port of Cohija silver-mines have 

 been discovered which are of great promise ; the present annual out-

Divides the formations of the island into six principal groups : — 

 1. Masses of various igneous rocks forming the highest part of the 

 island at its S.W. end. 2. A long series of unfossiliferous tuffs, clays, 

 and conglomerates. 3. Yery fossiliferous siliceous beds (land, fresh- 

 and brackish-water shells, &c.). 4. Series similar to 2. 5. A thick 

 formation of limestones and calcareous clays and sand, forming a third 

 of the island (corals, marine shells, &c.). 6. A calcareous series lying 

 unconformably on the last, and containing land, freshwater, and marine 

 forms of species now living on the island and in the surrounding sea.
