The frozen ocean was firm enough to have allowed of the passage of a park of artillery, or the erection of a monument, and many were the excursions on its surface until the sudden lowering of the temperature rendered all exertion so exhausting that they had to be discontinued. The pedestrians were out of breath after taking a few steps, and the dazzling whiteness of the glittering snow could not be endured by the naked eye; indeed, the reverberation or flickering glare of the undulatory reflection of the light from the surface of the snow, has been known to cause several cases of blindness amongst the Esquimaux. A singular phenomenon due to the refraction of rays of light was now observed: distances, depths, and heights lost their true proportions, five or six yards of ice looked like two, and many were the falls and ludicrous results of this optical illusion. On October 14th the thermometer marked 3° Fahrenheit below zero, a severe temperature to endure, especially when the north wind blows strongly. The air seemed to be made of needles, and those who ventured out of the house were in great danger of being frost-bitten, when death or mortification would ensue if the suspended circulation of the blood were not restored by immediate friction with snow. Garry, Belcher, Hope, and other members of the little community were attacked by frost-bite, but the parts affected being rubbed in time they escaped without serious injury. It will readily be understood that all manual labour had now become impossible. The days were extremely short, the sun was only above the horizon for a few hours and the actual winter, implying entire confinement within doors, was about to commence. The last Arctic birds forsook the gloomy shores of the Polar Sea, only a few pairs of those speckled quails remained which the Indians appropriately call “ winter birds,” because they wait in the Arctic regions until the commencement of the Polar night, but they too were soon to take their departure. Lieutenant Hobson, therefore, urged on the setting of the traps and snares which were to remain in different parts of Cape Bathurst throughout the winter. These traps consisted merely of rough joists supported on a square, formed of three pieces of wood so balanced as to fall on the least touch--in fact, the same sort of trap as that used for snaring birds in fields on a large scale. The end of the horizontal piece of wood was baited with venison, and every animal of a moderate height, a fox or a marten, for instance, which touched it with its paw, could not fail to be crushed. Such were the traps set in the winter over a space of several miles by the famous hunters whose adventurous life has been so poetically described by Cooper. Some thirty of these snares were set round Fort Hope, and were to be visited at pretty frequent intervals.
