Crampons are not for use on rocks, except possibly when iced, but they are particularly necessary on steep grass mountains, like the Höfats.
Spectacles and Grease.
Both spectacles and grease are very necessary on glacier expeditions. The spectacles can either be smoked glasses or, better still, the new green-yellow glasses. I prefer 1½ inch convexo-concave glasses in strong steel or horn frames without any wire netting.
The best grease for the face which I know is the Pomade Sèchehaye; but there are other similar preparations which rightly depend upon colour for their effectiveness. Lanoline is too thin. Blackening the face and all round the eyes with burnt cork is also an efficient remedy against sunburn, and suffices in the case of loss or breakage of spectacles. Or a mask of paper, with eye-slits, can be made.
Field-glass.
A Zeiss 8-power monocular prismatic glass weighs about a ½ lb., and can be carried in the pocket without any case for instant use.
The binocular glasses are too cumbersome.
This glass can also be used for sweeping terrain for chamois, but for detailed work a 30-power aluminium telescope is better.
Less effective, but lighter to carry, and sufficient for most alpine prospecting, is the pocket telescope, made by Messrs. Ross, for sporting purposes. It is about 4 inches in length, and weighs only a few ounces.
