"During the afternoon we were nearly becalmed, and witnessed some
magnificent eruptions of Mount Erebus, the flame and smoke being
projected to a great height; but we could not, as on a former occasion,
discover any lava issuing from the crater; although the exhibitions of
to-day were upon a much grander scale....

"Soon after midnight (February 16-17) a breeze sprang up from the
eastward and we made all sail to the southward until 4 A.M., although we
had an hour before distinctly traced the land entirely round the bay
connecting Mount Erebus with the mainland. I named it McMurdo Bay, after
the senior lieutenant of the Terror, a compliment that his zeal and skill
well merited."[10] It is now called McMurdo Sound.

In making the mistake of connecting Erebus with the mainland Ross was
looking at a distance upon the Hut Point Peninsula running out from the
S.W. corner of Erebus towards the west. He probably saw Minna Bluff,
which juts out from the mainland towards the east. Between them, and in
front of the Bluff, lie White Island, Black Island and Brown Island. To
suppose them to be part of a line of continuous land was a very natural
mistake.

Ross broke through the pack ice into an unknown sea: he laid down many
hundreds of miles of mountainous coast-line, and (with further work
completed in 1842) some 400 miles of the Great Ice Barrier: he penetrated
in his ships to the extraordinarily high latitude of 78° 11´ S., four
degrees farther than Weddell. The scientific work of his expedition was
no less worthy of praise. The South Magnetic Pole was fixed with
comparative accuracy, though Ross was disappointed in his natural but
"perhaps too ambitious hope I had so long cherished of being permitted to
plant the flag of my country on both the magnetic Poles of our globe."
