CHAPTER XVII.

THE APPROACH OF WINTER.

It was the 21st of September. The sun was then passing through the autumnal equinox, that is to say, the day and night were of equal length all over the world. These successive alternations of light and darkness were hailed with delight by the inhabitants of the fort. It is easier to sleep in the absence of the sun, and darkness refreshes and strengthens the eyes, weary with the unchanging brightness of several months of daylight.

We know that during the equinox the tides are generally at their greatest height; we have high water or flood, for the sun and moon being in conjunction, their double influence is brought to bear upon the waters. It was, therefore, necessary to note carefully the approaching tide at Cape Bathurst. Jaspar Hobson had made bench marks some days before, so as to estimate exactly the amount of vertical displacement of the waters between high and low tide; he found, however, that in spite of all the reports of previous observers, the combined solar and lunar influence was hardly felt in this part of the Arctic Ocean. There was scarcely any tide at all, and the statements of navigators on the subject were contradicted.

"There is certainly something unnatural here !" said Lieutenant Hobson to himself.

He did not in fact know what to think, but other cares soon occupied his mind, and he did not long endeavour to get to the rights of this singular peculiarity.

On the 29th September the state of the atmosphere changed considerably. The thermometer fell to 41° Fahrenheit, and the sky became covered with clouds which were soon converted into heavy rain. The bad season was approaching.

Before the ground should be covered with snow, Mrs Joliffe was busy sowing the seeds of Cochlearia (scurvy grass) and sorrel, in the hope that as they were very hardy, and would be well protected from the rigour of the winter by the snow itself, they would come up in the spring. Her garden, consisting of several acres hidden behind the cliff of the cape, had been prepared beforehand, and it was sown during the last days of September.

Hobson made his companions assume their winter garments before the great cold set in, and all were soon suitably clothed in the linen under vests, deerskin cloaks, sealskin pantaloons, fur bonnets, and waterproof boots with which they were provided. We may also say that the rooms were suitably dressed; the wooden walls were hung with skins, in order to prevent the formation upon them of coats of ice in sudden falls of temperature. About this time, Rae set up his condensers for collecting the vapour suspended in the air, which were to be emptied twice a week. The heat of the stove was regulated according to the variations of the external temperature, so as to keep the thermometer of the rooms at 50° Fahrenheit. The house would soon be covered with thick snow, which would prevent any waste of the internal warmth, and by this combination of natural and artificial protections they hoped to be able successfully to contend with their two most formidable enemies, cold and damp.

On the 2nd October the thermometer fell still lower, and the first snow storm came on; there was but little wind, and there were therefore none of those violent whirlpools of snow called drifts, but a vast white carpet of uniform thickness soon clothed the cape, the enceinte of fort, and the coast. The waters of the lake and sea, not yet petrified by the icy hand of winter, were of a dull, gloomy, greyish hue, and on the northern horizon the first icebergs stood out against the misty sky. The blockade had not yet commenced, but nature was collecting her materials, soon to be cemented by the cold into an impenetrable barrier.

The " young ice " was rapidly forming on the liquid surfaces of sea and lake. The lagoon was the first to freeze over; large whitish-grey patches appeared here and there, signs of a hard frost setting in, favoured by the calmness of the atmosphere. and after a night during which the thermometer had remained at 15° Fahrenheit, the surface of the lake was smooth and firm enough to satisfy the most fastidious skaters of the Serpentine.
