No description could give an adequate idea of the glory which flushed the northern sky, converting it into a vast dome of fire, but after the magnificent spectacle had been enjoyed for about half an hour, it suddenly disappeared-not fading gradually away after concentration of its rays, or a diminution of its splendour, but dying abruptly, as if an invisible hand had cut off the supply of electricity which gave it life. It was time it was over, for the sake of Thomas Black, for in another five minutes he would have been frozen where he stood ! CHAPTER XIX. A NEIGHBOURLY VISIT. On the 2nd December; the intensity of the cold decreased. The phenomena of the lunar halo and Aurora Borealis were symptoms which a meteorologist would have been at no loss to interpret. They implied the existence of a certain quantity of watery vapour in the atmosphere, and the barometer fell slightly, whilst the thermometer rose to 15° above zero. Although this temperature would have seemed very cold to the inhabitants of a temperate zone, it was easily endured by the colonists. The absence of wind made a great difference, and Hobson having noticed that the upper layers of snow were becoming softer, ordered his men to clear it away from the outer approaches of the enceinte. Mac-Nab and his subordinates set to work zealously, and completed their task in a few days. The traps were now uncovered and re-set. A good many footprints showed that there were plenty of furred animals about the cape, and as they could not get any other food, it was probable that the bait in the snares would soon attract them. In accordance with the advice of Marbre the hunter, a reindeer trap was constructed in the Esquimaux style. A trench was dug twelve feet deep, and of a uniform width of ten feet. A see-saw plank, which would rebound when lowered, was laid across it. A bait of herbs was placed at one end of the plank, and any animal venturing to take them, was inevitably flung to the bottom of the pit, and the plank immediately returning to its former position, would allow of the trapping of another animal in the same manner. Once in, there was no getting out. The only difficulty Marbre had to contend with in making his trap, was the extreme hardness of the ground to be dug out, but both he and the Lieutenant were not a little surprised at finding beneath some five feet of earth and sand a bed of snow, as hard as a rock, which appeared to be very thick. After closely examining the geological structure of the ground, Hobson observed: “This part of the coast must have been subjected to intense cold for a considerable length of time a great many years ago. Probably the ice rests on a bed of granite, and the earth and sand upon it have accumulated gradually.” “Well, sir, our trap won’t be any the worse for that, the reindeer will find a slippery wall, which it will be impossible for them to climb.” Marbre was right, as the event proved.
