the coast trends S.E. from Adelie Land, and could 
not possibly have been sighted from Wilkes's position. 
Wilkes reported having sighted land or appearance of land 
3000 feet high several times, seen over the fast ice, and 
he was within a few miles of a coast beyond Sabrina Land, 
which he called Knox Land. He then stood to the north 
and reported land ahead trending north in 64 0 , which he 
called Termination Land, but we now know that this 
does not exist. 
Captain Wilkes's theory has been proved to be quite 
correct — that there is a continuous land forming a coast- 
line of 2000 miles and more, and he certainly made out 
the distant land on several occasions, as Balleny and 
Dumont D'Urville had done before him, but his subsequent 
controversies are to be deplored.
