122 Report of the Board of Shell Fish Commissioners 



veyed and described with reference to triangulation stations on ," 

 shore. 



6. A duplicate series of nine polyconic projections have been 

 constructed on which the sextant positions, which determine 

 the location of the legal boundaries of the natural bars in Anne 

 Arundel County, have been plotted. A similar duplicate series 

 of projections showing the location of the legal boundaries of 

 the natural bars and crabbing grounds of Somerset County are 

 in process of construction as this report goes to press. 



These projections, together with the angle and sounding 

 record books which have also been duplicated, constitute the 

 original records of all positions established by the Commis- 

 sion and will be filed, one series in the office of the Commission 

 at Annapolis', the other in the office of the Coast and Geodetic 

 Survey in Washington. 



7. A large edition of a series of four charts, prepared from 

 the projections above mentioned and from data previously 

 gathered by the Coast and Geodetic Survey, showing the , 

 natural oyster bars of Anne Arundel County waters and waters 

 adjacent thereto; the location and names of all landmarks used 

 in making the survey ; the boundaries of the waters within the 

 territorial limits of the county and the boundary of the water 

 not within these limits but open for leasing with the county ; 

 the lines showing the 6, 18, 30 and 60-foot curves, with various 

 other topographical features, have been published by the Coast 

 and Geodetic Survey on the scale of 1 part in 20,000 and filed 

 with the Commission for distribution. 



8. A progress map has also been prepared and published by 

 the Coast and Geodetic Survey, on a scale of 1 part in 100,000 

 covering in outline the entire area of the county and giving the 

 scheme of the projections and published charts, showing all 

 triangulation stations and boundary lines of county and 

 adjacent waters. 



9. A series of 13 leasing charts have been constructed by the 

 Commission covering the entire area surveyed in Anne Arundel 

 County and are on file in the office of the Commission at An- 

 napolis. Those covering areas in which lots, leased for oyster 

 culture, are limited to ten acres are on a scale of 1 part in
