Good mountain aneroids, graduated to 5000 metres, are made by Casella, London, and by Usteri-Reinacher, Zurich. Even on an ordinary expedition they are interesting, and can be useful to elucidate one’s position in thick weather.
A compass must always be carried. Hughes, 59 Fenchurch Street, E.C., make an excellent liquid-filler compass which renders the needle very steady.
Maps.
The best map of the district must always be carried with the party.
Water-bottle and Drinking-cup.
I have for many years used bottles made of Para rubber with wide (1¼-inch) mouth and screw stopper. Contents 1 litre, weight 6 ounces, price 6½ marks (H. Schwaiger, Munich). If cured for a few days with weak white wine and water or coffee they do not impart any taste to contents, even if left in for a couple of days. When empty, they take next to no room.
The full bottle must, of course, be perched on top of the other things in the sack.
Guides prefer a tin or aluminium receptacle to hold two or three litres, and the goatskin bottles usual in Dauphiné are also very practical. As a drinking-cup I know nothing better than the ¼-litre oval aluminium mug of the Federal troops.
Carry an aluminium dessertspoon.
