As we passed through this chain of bergs we observed large masses continually falling from them, giving proof of their rapid destruction, even in this high latitude, and forming long streams of heavy loose fragments to leeward of them.

A great many whales were seen, chiefly of the common black kind, greatly resembling, but said to be distinct from, the Greenland whale: sperm, as well as hunchbacked whales, were also observed; of the common black species we might have killed any number we pleased: they appeared chiefly to be of unusually large size, and would doubtless yield a great quantity of oil, and were so tame that our ships sailing close past did not seem to disturb them.
