the savage, with his narrow sphere of observation and his short-lived tradition, lacks the very elements of that experience which alone could set his mind at rest in face of the ever-changing and often menacing aspects of nature. No wonder, therefore, that he is thrown into a panic by an eclipse, and thinks that the sun or the moon would surely perish, if he did not raise a clamour and shoot his puny shafts into the air to defend the luminaries from the monster who threatens to devour them. No wonder he is terrified when in the darkness of night a streak of sky is suddenly illumined by the flash of a meteor, or the whole expanse of the celestial arch glows with the fitful light of the Northern Streamers.(722) Even phenomena which recur at fixed and uniform intervals may be viewed by him with apprehension, before he has come to recognise the orderliness of their recurrence. The speed or slowness of his recognition of such periodic or cyclic changes in nature will depend largely on the length of the particular cycle. The cycle, for example, of day and night is everywhere, except in the polar regions, so short and hence so frequent that men probably soon ceased to discompose themselves seriously as to the chance of its failing to recur, though the ancient Egyptians, as we have seen, daily wrought enchantments to bring back to the east in the morning the fiery orb which had sunk at evening in the crimson west. But it was far otherwise with the annual cycle of the seasons. To any man a year is a considerable period, seeing that the number of our years is but few at the best. To the primitive savage, with his short memory and imperfect means of marking the flight of time, a year may well have been so long that he failed to recognise it as a cycle at all, and watched the changing aspects of earth and heaven with a perpetual wonder, alternately delighted and alarmed, elated and cast down, according as the vicissitudes of light and heat, of plant and animal life, ministered to his comfort or threatened his existence. In autumn when the withered leaves were whirled about the forest by the nipping blast, and he looked up at the bare boughs, could he feel sure that they would ever be green again? As day by day the sun sank lower and lower in the sky, could he be certain that the luminary would ever retrace his heavenly road? Even the waning moon, whose pale sickle rose thinner and thinner every night over the rim of the eastern horizon, may have excited in his mind a fear lest, when it had wholly vanished, there should be moons no more.
