1- The following tables and graphs pbce in convenient storage the results of several years of ca refu l surveying and at the same titne provide rudjmentary interpretation of resu Its by comparing: eros ion rates. The reader will find listed in the bibliography pertinent pubLished papers which analyze these coastal erosion data in great detail. The Marindin Surveys Mr. Henry Marindin, an assistant to the Superintendent of the U . S. Coast and Geodetic Survey, conducted a most interesting and

... hwhile series of measurements which allowed him to determine the rates of erosion on the cliffs and beaches of Outer Cape Cod (Marindin , ·1889, 1891). These were made from August 1887 through 1889. lines in Provincetown Harbor were surveyed in 1890. In brief, Marindin established a series of points , 229 in all,approx imately 300 meters apart along almost the entire eastern coast of Cape Cod and on around the Provincelands hook (Figures 1-6F ). From these points, which he marked in the field by oake n stakes, he pub I ished measured distances and elevations over the ground more or less at ri ght angles to the coast. The elevations were established on a mean sea level daf'.um that he derived from tidal observations made at Chatham, in 1887. Marindin located his or igins in terms of latitude and long. itude but, because of a change in the geodetic grid , it is necessa ry to correct his origins by subtracting· 0. 6 secE>nd from each of his latitudes in order to plot the points on contemporary charts. This survey, .which was carried out under the usual adversities of scrubby vegetation and variable weather,technica lly was an excellent job . After repeating some of his measurements we fully appreciate Marindin 1 s difficulties and accompl ishments.
