^{page 221 note †} Some of these observations have been briefly recorded in the Summary of Progess for 1897 and 1898. Sec also Harker, “Glaciated Valleys in the Cuillins, Skye,” Geol. Mag. 1899, pp. 196–199. In the following pages the subject is developed more fully than would be convenient in an official publication.

^{page 222 note *} The maps illustrating the present paper are, Scotland (one-inch), sheets 70 and 71; Skye (six-inch), sheets 38, 39, 44, 45, 49, and 50. A reduced copy of the six-inch map of the Cuillins, with additional names and heights, is given in No. 25 of the Scottish Mountaineering Club Journal, issued January 1898. For some corrections of the topography of the ridges, see a rough sketch map by C. Pilkington, pub. 1890 (Manchester); also Douglas, W., S.M.O.J., vol. iv. pp. 209–213, 1897Google Scholar: and A. Harker, ibid., vol. vi. pp. 1–13, 1900.

^{page 223 note *} “The lofty Coolin Mountains of Skye …. formed of themselves a centre of dispersion, but the northern parts of the island were overflowed by the ice that crest out from the great glens of Ross.”—The Great Ice Age, p. 83 nf third edition, 1894.

^{page 223 note †} It would perhaps be more accurate to say that if, at an early stage, the Scottish ice did obtain a footing among the Skye mountains, it has left absolutely no trace of its occupation; and the episode, if it ever occurred, is not to be reckoned with as a factor in the glaciation of the area as it is now to be studied.

^{page 224 note *} This remark applies to the occasional boulders, some of large size, found in places along and above the sealochs. Where the present coast-line lies near what was the boundary of the Scottish ice, as in many places between Broadford and Loch Ainort, we find on the beach more numerous fragments of foreign rocks, doubtless washed out of the ground-moraine of the Scottish ice-sheet.

^{page 231 note *} Harta Corrie is the only exception, and here we have already seen that, at the maximum glaciation, the ice when it reached the curve no longer followed the direction of the valley.

^{page 233 note *} Something comparable with this has been described by Dr W. T. Blanford in the Great Glen of Scotland (“On a Particular Form of Surface, apparently the Result of Glacial Erosion, seen on Loch Lochy and Elsewhere,” Quart. Journ. Geol. Soc., vol. lvi. pp. 198–203, pl. ix., 1900Google Scholar). There are, however, considerable differences between the two cases.

^{page 239 note *} The principal difficulty was in finding sufficiently calm weather. In a wind it was found impossible to keep the boat in place while a sounding was made and the position determined.
