It is, perhaps, even more difficult to determine how far the Franz Josef Land archipelago stretches to the eastward. From all we saw, I should judge that Wilczek Land cannot be of any great extent; but there may nevertheless be new islands farther to the east. This seems probable, indeed, from the fact that in June and July, 1895, we remained almost motionless at about 82° 5' north latitude, in spite of a long continuance of northerly winds; whence it seemed that there must be a stretch of land south of us obstructing, like a long wall, the farther drift of the ice to the southward. But it is useless to discuss this question minutely here, as it, too, will doubtless be answered authoritatively by the English expedition. Another feature of Northbrook Island which greatly interested me was the evidence it presented of changes in the level of the sea. I have already mentioned that Jackson's hut lay on an old strand-line or terrace about from 40 to 50 feet high, but there were also several other strand-lines, both lower and higher. Thus I found that Leigh Smith, who also had wintered on this headland, had built his hut upon an old strand-line 17 feet above the sea-level, while at other places I found strand-lines at a height of 80 feet. I had already noticed such strand-lines at different elevations when I first arrived in the previous autumn at the more northern part of this region (for example, on Torup's Island). Indeed, we had lived all winter on such a terrace. Jackson had found whales' skeletons at several places about Cape Flora. Close to his hut, for instance, at a height of 50 feet, there lay the skull of a whale, a balæna, possibly a Greenland whale (Balæna mysticetus?). At a point farther north there lay fragments of a whole skeleton, probably of the same species. The underjaw was 18 feet 3 inches long; but these bones lay at an elevation of not more than 9 feet above the present sea-level. I also found other indications that the sea must at a comparatively recent period have risen above these low strand-terraces. For instance, they were at many points strewn with mussel-shells. This land, then, seems to have been subjected to changes of level analogous to those which have occurred in other northern countries, of which, as above mentioned, I had also seen indications on the north coast of Asia.
