16th. We travelled across the ice-mountain. After we had walked for a while, we saw a dense cloud in the north-east. We saw it both above and below us and, when it finally reached us, it made our clothes dampish but our hair became really wet, which is interesting. It hid the horizon from us and we could see neither sun nor moon nor, indeed, the surrounding mountain peaks. We had no idea which way to turn, fearing that on one side we should fall over the precipice and put an end to the farce just as a Lapp did a few years ago, or that we should fall the other way and end up in a river that had cut so far down into the snow that merely looking down made us dizzy. We could see no more than 4 feet in front of us. We were in the same situation as an inexperienced sailor who, in a storm at sea when the land is out of sight, fears cliffs on all sides and has no compass. Even the Lapps think it hard going when they find themselves in this sort of situation. But, even though we had no guide, good fortune led us to a reindeer trail made recently by someone canying goods over to Norway, and that showed us the way.
