FOR STORM.
41. If the clouds be of different heights, the sky above being grayish or dirty blue, with hardly any wind stirring; the wind, however, changing from W. to S., or sometimes to S. E., without perceptibly increasing in force.
42. If there be a clouded sky, and dark clouds driving fast (either with the wind or more from the south), under the higher clouds, violent gusts of wind.
43. If there be long points, tails, or feathers hanging from thunder or rain-clouds, five, six, or more degrees above the horizon, with little wind in summer, thunder may be expected; but the storm will be generally of short duration.
44. If there be a light blue sky, with thin, light, flying clouds, whilst the wind goes to the south without much increase in force; or a dirty-blue sky, where no clouds are to be seen; storm.
45. If the sun be seen double, or more times reflected in the clouds, expect a heavy storm.
46. If the sun set with a very red sky in the east, expect stormy wind.
47. If two or three rings be seen round the moon, which are spotted and spread out, expect a storm of long continuance.
48. If porpoises and whales sport about ships.
49. If sea-gulls and other birds fly inland.
50. Storms are most frequent in December, January and February. In September, there are generally one or two storms. If it blow in the day, it generally hushes toward evening; but if it continue blowing then, it may be expected to continue. The vernal equinoctial gales are stronger than the autumnal.
