I n a paper published in the preceding volume of this Journal, an account was given of the glacial phenomena observed in Spitsbergen by Dr. Gregory and myself during our visit with Sir Martin Conway in 1896. The work accomplished that year was practically confined to observations made in the valleys lying to the east of Ice Fjord, namely Advent Vale and Sassendal, with their tributary glens and connecting passes. Over this district there is no approach to a continuous sheet of ice; our detailed investigations were therefore limited to an examination of the small glaciers occurring over restricted areas, or debouching into the larger lateral valleys, from the icefields to the north. The time at our disposal that year did not admit of an expedition on to the inland ice, marked in the chart as occurring farther north, of which we caught glimpses on more than one occasion from the summits of the Sassendal peaks. From the views, however, which we obtained, this district promised to afford admirable material for the study of ice-action on a large scale. As no information could be procured regarding the character of the interior of the northern part of West Spitsbergen, save that the chart bore the mysterious legend ‘high inland ice,’ a term which we had found on previous occasions to be synonymous with ‘unexplored,’ I decided to revisit the island, and was fortunate in persuading Sir Martin Conway to join me on an expedition during the summer of 1897 into the interior
