F. P. GULLIVER — NANTUCKET SHORELINES 



half century, however, there have been two forelands built out in front of 

 this maturely developed shoreline. One of these forelands is the low 

 bathing beach in front of 'Sconset bluffs, and the discussion of its forma- 

 tion will be left to a later paper. The other is what the writer would 

 call Miacomet foreland, which has been built out in front of Weweeder 

 and Miacomet ponds, to the west of the Weweeder Life Saving station, 

 about 3 miles south of the town (figure 2). 



In September, 1903, the writer made a planetable survey of this fore- 

 land, marking several stations on the foreland and on the former shore- 

 line with iron pipes sunk in the sand, to enable accurate measurement of

the advance and retreat of the shoreline to be made in this region. This 

 planetable map, showing the location of these fixed stations, is here re- 

 produced on a scale of 1 : 10,000. The line A-B was measured with a 

 tape and found to be 1,179.34 feet. These two stations, A and B, were 

 occupied by the planetable and the other stations shown on the map 

 were located by graphic triangulation. Offsets to the shoreline were 

 measured at many points, so that the high and low tide lines, as given 

 on this map, are practically correct for the scale. The detailed surface 

 form, showing dune ridges and hollows between the dunes, was obtained 

 by means of many intermediate planetable stations.
