Nor were the troubles of the drivers limited to the dogs. The whip which is used for sledge teams consists of a very short handle and a very long lash. In the hands of an expert it is a most effective weapon, being capable of producing a resounding crack or a stinging blow wherever the wielder desires. But in the hands of a novice it is, like the Australian stock-whip, prone to do everything that the wielder does not wish. The amateur driver of a team, growing impatient as his dogs set off at full speed in various directions, and, besides tangling the harness, upset the sledge and themselves and very nearly himself as well, lashed out viciously at the worst offender; but the lash, instead of bringing the creature to his senses, curled back and hit the striker across the face, or twined round the legs of his companion, with disastrous results. Meanwhile the Eskimo driver was going from one group to another, trying to explain the mysteries of the art, much to the amusement of the onlookers and the indignation of the inexperienced amateurs. During the wait at Disko, another form of Arctic travelling was practised by the officers of the expedition. This was the use of the Eskimo kayak. The kayak is a long narrow canoe, entirely covered in with a waterproof covering. The voyager sits in the middle in a small round hole, the covering lapping over the edges and being fastened round the waist. The kayak is thus made as buoyant as a life-belt, whether floating on an even keel or upside down. By reason of their build, they are peculiarly "cranky" craft, turning over at the least provocation, and so require extremely careful handling, unless one is an adept at swimming and diving. The experience of one of the officers made this clear. He had securely strapped himself in, when, by a false stroke of the paddle, he overturned the kayak. He could not get it back again and was unable to loosen the cover; there was only one way of escape, and that possible alone to a man familiar with being under water. Loosening his clothes, he wriggled out of them and came to the surface just in time to avoid drowning.
