208 LETTER TO DR. KETCHELL. 



and geographical position of the county were favorable to such a 

 course ; as being long and narrow, and surrounded on three sides 

 by water, there was little chance for error in laying down its topo- 

 graphy entirely with the plane-table. That portion already sur- 

 veyed by. the general government, has simply been revised without 

 going over all its details. 



It is presumed that the characters used in delineating the topo- 

 graphy will be comprehended without explanation. The salt 

 meadow can be readily distinguished from the upland ; the culti- 

 vated land from the wooded ; and the cedar swamps from the dry 

 forest. 



In submitting this Map to the citizens of the county, I beg to 

 express the hope that it will meet their expectations ; and I will 

 add the conviction that, coupled with Professor Cook's Geological 

 Report, it will be of great value not only to them but to every 

 citizen of the State. 



Very respectfully. 



Your obedient servant, 



EGBERT L. VIELE.
