which was sewn down to that which was already fixed. The other end was left open, and had two triangular flaps that overlapped each other, and which were fastened up when we were inside by pieces of tape. Lastly, the forfar was nailed down to the poles to prevent the tent getting out of shape. The cord which was used for climbing served for the tent; it was passed over the crossed poles and underneath the ridge of the roof, and the two ends—one fore and the other aft—were easily secured to pieces of rock. Such a tent costs about four guineas, and its weight is about twenty-three pounds; or, if the lightest kind of forfar is used, it need not exceed twenty pounds. When it was fastened up for transport it presented the appearance shown in the portrait of Meynet at p. 234, and it could be unrolled and set up by two persons in three minutes; a point of no small importance during extreme weather. [Illustration: Diagram to show manner of fastening tent-poles] [Illustration: THE AUTHOR’S MOUNTAIN TENT.] This tent is intended, and adapted, for camping out at high altitudes, or in cold climates. It is not pretended that it is perfectly waterproof, but it can be made so by the addition of mackintosh to the roof; and this increases the weight by only two and a half pounds. It is then fit for general use.(52) It may be observed that the pattern of this tent is identical in all essential points with that arrived at (after great experience) by Sir Leopold M’Clintock for Arctic work, and frequent use by many persons, under varied conditions, has shown that the pattern is both practical and substantial.
