(and it must be remembered that “day” and “night” in those regions are very equivocal terms).  There are, besides, a cooking-apparatus, of which the fire is made in spirit or tallow lamps, one or two guns, a pick and shovel, instruments for observation, pannikins, spoons, and a little magazine of such necessaries, with the extra clothing of the party.  Then the provision, the supply of which measures the length of the expedition, consists of about a pound of bread and a pound of pemmican per man per day, six ounces of pork, and a little preserved potato, rum, lime-juice, tea, chocolate, sugar, tobacco, or other such creature comforts.  The sled is fitted with two drag-ropes, at which the men haul.  The officer goes ahead to find the best way among hummocks of ice or masses of snow.  Sometimes on a smooth floe, before the wind, the floor-cloth is set for a sail, and she runs off merrily, perhaps with several of the crew on board, and the rest running to keep up.  But sometimes over broken ice it is a constant task to get her on at all.  You hear, “One, two, three, haul” all day long, as she is worked out of one ice “cradle-hole” over a hummock into another.  Different parties select different hours for travelling.  Captain Kellett finally considered that the best division of time, when, as usual, they had constant daylight, was to start at four in the afternoon, travel till ten P.M., breakfast then, tent and rest four hours; travel four more, tent, dine, and sleep nine hours.  This secured sleep, when the sun was the highest and most trying to the eyes.  The distances accomplished with this equipment are truly surprising.  Each man, of course, is dressed as warmly as flannel, woollen cloth, leather, and seal-skin will dress him.  For such long journeying, the study of boots becomes a science, and our authorities are full of discussions as to canvas or woollen, or carpet or leather boots, of strings and of buckles.  When the time “to tent” comes, the pikes are fitted for tent-poles, and the tent set up, its door to leeward, on the ice or snow.  The floor-cloth is laid for the carpet.  At an hour fixed, all talking must stop.  There is just room enough for the party to lie side by side on the floor-cloth.  Each man gets into a long felt bag, made of heavy felting literally nearly half an inch thick.  He brings this up wholly over his head, and buttons himself in.  He has a little hole in it to breathe through.  Over the felt is sometimes a brown holland bag, meant to keep out moisture.  The officer lies farthest in the tent,—­as being next the wind, the point of hardship and so of honor.  The cook for the day lies next the doorway, as being first to be called.  Side by side the others lie between.  Over them all Mackintosh blankets with the buffalo-robes are drawn, by what power this deponent sayeth not, not knowing.  No watch is kept, for there is little danger of intrusion.  Once a whole party was startled by a white bear smelling
