Extract

In 1877 and the following year Colonel H. W. Feilden published the results of his scientific investigations on the coasts of Smith Sound and the channel to the north. In 1896 he made contributions to the geology of Kolguev, Waigats, and Novaya Zemlya in two other papers. These are reprinted, together with one previously unpublished, in the appendix to Mr. H. J. Pearson's book, “Beyond Petsora Eastward” (1899). As the earlier work appears to have been forgotten by some writers upon glacial subjects, and the last-named might very easily escape their notice, I urged Colonel Feilden to give a summary of his chief results in some generally accessible periodical. Shortly afterwards, on being unexpectedly called away for service in South Africa, he requested me to undertake the task. For the sake of brevity, I restrict myself mainly to the investigations which throw light on the formation of Boulder-clay and its associated sands and gravels, because these establish two points: (1) that such deposits are sometimes formed beneath the sea; (2) that the land in these Arctic regions has been elevated, in places not less than a thousand feet, since either some time in or the close of the Glacial epoch.
