I have reason to think from what I have seen, that there are compara- 

 tively few localities where these North Carolina hill gravels can be suc- 

 cessfully worked at present ; that in any event the returns — considering 

 the risk — will be small; that no "bonanza" need be expected, though 

 local deposits of very rich gravel will undoubtedly be found ; and that no 

 operations can be successful unless the strictest economy is observed in all 

 the details both of management and worJcing.
