 pp. 147, 150. 



The papers of Baylies and West are of historical interest as the first published ac- 

 counts of Gay Head. The contorted beds and fossils are mentioned, but the cliffs are 

 supposed to have been formed by a volcano.

and Arts, 7, pp. 31-43. Paper read before Acad. Nat. Sci., Philadelphia, July 15,

Refers the beds and Gay Head to the Tertiary system and compares them to 

 those at Alum Bay, on the Isle of Wight. 



1824. Hitchcock, Edward. Notices of the geology of Marthas Vineyard and the Elizabeth 



Islands: Am. Jour. Sci. and Arts, 7, pp. 240-248. 



Recognizes three formations at Marthas \ r ineyard: (1) Alluvium (the outwash 

 plain) ; (2) diluvium (the morainal area) ; and (3) plastic clay formation. Places the 

 plastic clay in the Tertiary system.
