Scope of the Paper 



During the past year the writer has continued his studies of the recent 

 changes in the shorelines of the island of Nantucket, and the results of 

 such study are given in this paper. Details of the changes are presented 

 in the following areas: Great point, Coskata, Haulover break, Surfside, 

 Maddaket, Smith point, Brant point, Nantucket harbor, and Coatue (see 

 figure 1). 



This second paper on Nantucket shorelines describes some of the de- 

 tailed work of 1902-1903. The first point considered will be the long arm 

 projecting from the north of the island toward Monomoy point, which 

 projects southward from the elbow of cape Cod. 



Great Point 



Great point and Monomoy are two great masses of sand worn respect- 

 ively from the east side of Nantucket and the east side of cape Cod, carried 

 along by the action of the waves, tides, and currents to the north from 

 Nantucket, to the south from cape Cod, and then blown up by the winds
