Travel at night.—Night travel has most of the disadvantages of travel in storm. Although the weather may be more agreeable, visibility, even during brilliantly moonlit nights, is much poorer and travel should be slower. The precautions are the same as for storm travel; in addition, each group of four should be equipped with a headlight, and the battery should be worn so that the cells will be kept warm. The life of the cells will be longer if the light is used intermittently, and small portions of the route remembered until it is necessary to use the light again. The man with the light should remember the handicap of those behind, and that the farther behind they are, the greater is their handicap. |
