1 8 Survey of Oyster Bars, Somerset County, Md. 



From June 25 to November 6, when the field work in Somerset and Wicomico 

 counties was practically completed, the usual routine of field and office work was followed 

 without material interruption except that resulting from the moving of the house boat 

 Oyster from Crisfield to Manokin River on July 13, then to Piney Island on August 27, 

 and to Wicomico River, on August 30, where she remained until her removal to Nanti- 

 coke River on September 30. 



From this latter date the work in Wicomico County predominated, and when the 

 field surveys were practically completed on November 6 the entire party left by rail for 

 Worcester County, it being impracticable to move the house boat to the waters of that 

 locality. 



At the close of the survey work in Worcester Courity in the last part of December, 

 office work relating to Somerset and Wicomico counties was actively commenced at 

 Baltimore and was continued without material interruption until March 23, 1908, 

 when a subparty went to Worcester and Somerset counties to finish some details of field 

 work in those sections required for the preparation of the technical reports and oyster 

 charts. 



The very large amount of work of computation and drafting necessary to make the 

 results of the survey of the previous season available for publication was nearly com- 

 pleted on May 2, when it was transferred to the Government quarters on the house boat 

 Oyster, which left Baltimore on the same day with the party and outfit for her anchorage 

 off Solomons Island, in the Patuxent River. 



The active field work in Calvert County dates from May 2, but from that time until 

 the filing of this report and the oyster charts of Somerset County the chief of party, in 

 addition to his regular field duties, was frequently at Baltimore and Washington to look 

 after their final preparation for publication.

 records for future use in connection with the preparation of new editions of charts of the waters of 

 Maryland.
