"It appears," continued Bainbridge, on the following evening, "that Hili-li was subject to the recurrence about once in forty-seven years of a strange thermic phenomenon, the mean duration of which was about fifty hours. This change had occurred twenty-one times in the preceding thousand years; its duration had once been as brief as thirty hours, and at another time had lasted one hundred and twenty hours. The interval between two of its visitations had once been somewhat less than eight years; whilst at the period of Pym and Peters' presence in Hili-li, it had not occurred for eighty-six years and some months. For some reason that could not be conjectured, at these times the wind-currents, generally varying but slightly in force and duration, changed, the wind coming from a point of the compass almost diametrically opposite to its usual direction, and increasing in velocity and force to that of a tempest or blizzard. The result was, that in a very few hours the temperature of Hili-li fell to about zero Fahrenheit, if in December or January; to 60° or 70° Fahrenheit below freezing, if in July or August. During the first few hours of the change, owing to the extremely moist state of the atmosphere for many miles in all directions from the crater of Hili-li, there occurred a heavy snowfall--which, however, diminished as the temperature fell, until at somewhat above the zero point it ceased. "The government of Hili-li, by laws and by the encouragement of custom, did much to prevent damage from these storms--which, as I have intimated, were a combination of hurricane and snow-storm, with a very sudden and rapid fall of temperature; and when the interval between two of them was not greater than twenty years, the provisions made by the state were ample to prevent loss of life. By the law of the land, residence houses had to be built in such a manner that at least one room in each house could be warmed by a fire. Fire for purposes of warmth was never in Hili-li required, except during these storms; and all cooking was done on a peculiar stove made chiefly of gold, the fuel of which was either fish oil, or another oil termed by the boatmen who sold it 'continent oil'--or, rather, by a name corresponding in the Hili-li language to those words in the English. The law further provided that on the premises of each home wood should be kept, ready for use, in chests of a size convenient for two persons to carry into the room in which it was to be burned. By this means, the worst that could happen to a family was that its members might suddenly at any time be confined to a single room, comfortably warmed, for from thirty to a hundred hours, or thereabouts. Even if there should be very little food in any one home, or if the wood supply should be neglected, the next door neighbor could be relied upon for succor.
