THE ARCTIC REGIONS. 43 is well-known that the sun shines at the North Pole continuously for 6 months, and then sinks down below the horizon, producing a night of 6 months' duration. But a closer examination of the subject will show that the statement is only roughly true, and requires to be modified in several particulars before it can be accepted as scientifically accurate. In the first place we must distinguish between the Pole and the Polar regions. The Pole is merely a point, and all the inhabitants of the original ancient home, if there was one near the North Pole, could not have lived precisely at this single point. The Polar or the Arctic regions, on the other hand, mean the tracts of land included between the North Pole and the Arctic circle. But the duration of day and night, as well as the seasons, at different places within the Arctic regions cannot be, and are not, the same as at the point called the North Pole. The characteristics of the circum-polar region may indeed be derived from the strictly Polar characteristics; but still they are so unlike each other that it is absolutely necessary to bear this distinction in mind in collecting evidence of a circum-polar Aryan home in ancient times. Men living round about the Pole, or, more accurately speaking, in regions between the North Pole and the Arctic circle, when these regions were habitable, were sure to know of a day and night of 6 months, but living a little southward from the Pole, their own calendar must have been different from the strictly Polar calendar; and it is, therefore, necessary to examine the Polar and the circum-polar charac- teristics separately, in order that the distinction may be clearly understood. The terrestrial Poles are the termini of the axis of the earth, and we have seen that there is no evidence to show that this axis ever changed its position, relatively to the earth, even in the earliest geological eras. The terrestrial poles and the circum-polar regions were, therefore, the same
