CHAP. 82.—PROGNOSTICS DERIVED FROM CLOUDS.

When clouds are seen moving in a clear sky, wind may be expected in the quarter from which they proceed; but if they accumulate in one spot, as they approach the sun they will disperse. If the clouds are dispersed by a north-east wind, it is a presage of high winds, but if by a wind from the south, of rain. If at sunset the clouds cover the heavens on either side of the sun, they are indicative of tempest; if they are black and lowering in the east, they threaten rain in the night, but if in the west, on the following day. If the clouds spread in large numbers from the east, like fleeces of wool in appearance, they indicate a continuance of rain for the next three days. When the clouds settle on the summits of the mountains,¹ there will be stormy weather; but if the clouds clear away, it will be fine. When the clouds are white and lowering, a hailstorm, generally known as a "white"² tempest, is close at hand. An isolated cloud, however small,³ though seen in a clear sky, announces wind and storm.

1 Theophrastus states to a similar effect, and it is confirmed by the experience of those who live in mountainous countries.

2 We still hear of the "white squalls" of the Mediterranean.

3 "`Behold, there ariseth a little cloud out of the sea, like a man's hand.'—And it came to pass in the meanwhile, that the heaven was black with clouds and wind, and there was a great rain."—1 Kings, xviii. 44, 45.
