The blizzard first breaks up the sea ice, then piles it as drift pack against thesouthern side of the Tongue. The jagged tilted slabs of this pack ice shelter thedrifting snow, and give origin to sastrugi of exceptional size. It is obvious that thedrift snow which has helped to round off the weather side of this Tongue is carriedin enormous quantities across it, forming immense drifts to leeward, that is, onits northern side. It may be suggested that these drifts, forming at first on seaice, if the sea ice does not break away the same year, may eventually pass into asjDecies of barrier formation, partly ice, partly old snow. That this Tongue is afloat is, we think, proved by the entiie absenc
