Putnam.] 236 [March 16, 



Note. — It is a pleasure to me to acknowledge ray obligation to Dr. St. Julien 

 Ravenel for the great assistance kindly rendered by him during my examina- 

 tion of the South Carolina beds; he, having been the first to see the commer- 

 cial value of these beds and a constant student of their features since their 

 discovery, is now the person best acquainted with their phenomena. I account 

 it a very fortunate thing that I had his guidance over a considerable part of the 

 region I traversed.
