The general character of the island and its ecological features 

 as regards the vegetation have been described by Lewis and Miss 

 Shaw in the report previously mentioned. While the vegeta- 

 tional environments are of interest in connection with the con- 

 sideration of the fauna, it would be superfluous to restate here 

 the data to be found in that publication, especially in the section 

 on "Ecology of Penikese" by Miss Margaret F. Shaw. It is 

 necessary to give only a single quotation from Lewis (below) 

 and to say that the small rocky island is practically devoid of 

 trees, and, except where denuded of all vegetation in some of 

 the nesting grounds of terns, is given over to grasses and other 

 small plants, with rarely a low growing shrub or willow. 



"The island Penikese is a remnant of the terminal moramr 

 now seen in the Elizabeth Islands. It is about two thirds of a 

 mile long and half as broad, with a broadly spatulate point for 

 convenience of reference called Tub Point, extending further 

 to the east for another third of a mile. Its contour is dominated 

 by low hills on the main body of the island, with depressions here 

 and there which may be ponds of a rather temporary character
