Four small islands, named after the second engineer on board the 'Discovery,' 

 lie about twelve miles to the N. of Winter-quarters Bay, and about four miles to 

 the S.-W. of Mount Erebus. Off Tent Island, which is given in Fig. 2, a very large 

 number of Weddell Seals produce their young every spring, and it was here that 

 a large camp was formed while attempts were made to saw a channel in the ice 

 for the liberation of the ship in 1904. 



The gravel areas upon the summit of these rocky islets are occupied in the 

 summer months by scores of nesting Skua Gulls. The rock is entirely volcanic, 

 and the four islets are probably remnants of a once continuous land-mass, forming 

 part of Ross Island.
