Continuous recording of soundings throughout. Shortly after the return to the barrier the ship was forced to the north by a field of bergs surrounded by heavy pack-ice, and soundings reached a maximum of loiofm. (1847 m.) in 69° 54-8' 8, 03° 32-1' E. From this position the soundings again shoaled rapidly towards the land and after a steady slope a depth of 60 fm. (no m.) was obtained 3 cables off-shore, in 70° 04-6' S, 03° 49-2' E. Land was again approached a few miles farther east and the least sounding obtained was 117 fm. (214 m.). Course was then altered to avoid pack-ice and to stand off the coast during the dark hours, but the weather deteriorated rapidly during the night and it was not possible to resume the survey. THE CONTINENTAL SHELF OF ANTARCTICA This short survey of 140 miles of the ice barrier revealed the interesting fact that over this distance there was virtually no continental shelf in the sense generally understood. Unfortunately, the pack-ice which surrounds the Antarctic Continent throughout the greater part of the year in most sectors makes the approach difficult, and it is only during late summer or autumn that ships can expect to close the land. It is not possible, without much more information than we now possess,
