he not be satisfied of this ? When the whole world  shaii 
een as thoroughly explored as England has been, 
then, but not till then, can it be expected any general geo- 
logical theory will be formed, which will stand the test of 
ages. Ere two decades of years are gone by, we trust the 
geologists of the United States will have done their part of 
this great and interesting work. 
Arr. IL1.—Notices of the Geology of Marthas’s Vineyard, 
ee and the Elizabeth Islands.- 
A short visit to the island of Martha’s Vineyard, in the 
not coloured in the map of Maclure; and they may not 
soon be visited by a geologist, who will have any better op- 
portunity to examine their structure than I had, although! 
confess my researches were hasty and imperfect. This 
—_— however, may furnish some assistance to succeeding 
rvers. 
Martha’s Vineyard is about twenty one miles in its great- 
est length, and from six to eight in its greatest breadth. It 
is divided into three townships ,- Edgartown, the most pop- 
ulous, occupying the south eastern part of the island ; Tis- 
ury, embracing the north western part, and Chilmark the 
western and southwestern parts. The name of this island, 
given by the aborigines, is Nope, or Capawock. These 
natives have long been celebrated in the annals of missions- 
it those, whose blood runs pure fram foreign mixture, 
are now nearly extint. A hybrid race, however, descende 
chiefly from the intermarriages of negroes and indians, are 
yet considerably numerous, perhaps about four hundred, who 
inhabit the western extremity of the island, in the vicinity 
of Gay head; and among them, there exists an organize 
christian church. The small island of Chabaquiddick. lies 
at alittle distance from the east end of the vineyard, a0 
Noman’s land. not far from the south western extremity: 
The Elizabeth islands. being about sixteen in number, are 
situated a few miles from the north west end of Martha’s.
