Because when the air is damp it conveys the odours of flowers more effectively than it does when dry. Because the insects which the swallows pursue in their flight are flying low, to escape the moisture of the upper regions of the atmosphere. Because by wetting the outer coat of their feathers before the rain falls, by sudden dashes of water over the surface, they prevent the drops of rain from penetrating to their bodies through the open and dry feathers. Because they smell the fragrant perfume which is diffused in the air by its increasing moistness. "I will remember the works of the Lord: Surely I will remember thy wonders of old."—Psalm lxxvii. Because their skins are exceedingly sensitive to atmospheric influences, and they are oppressed and irritated by the changing condition of the atmosphere. Because those insects are highly sensitive to the state of the atmosphere, and when it is setting fine they build their webs, because they know instinctively that flies will be abroad. Because it shows that they are aware that the state of the atmosphere does not favour the flight of insects. Because it shows that they feel the state of the atmosphere to be favourable, which induces them all to leave their places of shelter. Because the birds are pleasurably excited by a favourable change in the atmosphere. Because owls scream when the weather is on the change; and when a patient is lingering on a death bed, the alteration in the state of the atmosphere frequently induces death, because the faint and expiring flame of life has not strength enough to adapt itself to the change. Because the insects, anticipating the approach of rain, remove their webs for preservation. "There shall the great owl make her nest, and lay, and hatch, and gather under her shadow: there shall the vultures also be gathered, every one with her mate."—Isaiah xxxiv. Because the bees feel instinctively that from the state of the atmosphere they may wander far in search of honey, without the danger of being overtaken by rain. Because the dampness of the atmosphere affects its pressure upon the body, and causes a temporary disturbance of the system. All general disturbances of the body, manifest themselves in those parts which are in a morbid state—as in a corn, a rheumatic bone, or a decayed tooth. Because plants are highly sensitive to atmospheric changes, and close their petals to protect their stamens. Because the moles know instinctively, that on the approach of wet, worms move in the ground; the moles therefore become active, and form their hills. Because magpies generally fly in company; but on the approach of wet or cold, one remains in the nest to take care of the young, while the other one wanders alone in search of food. Because the fishes swim near to the surface of the sea, and the birds assemble over the sea to catch the fish, instead of sitting on rocks, or wading on the shore. Because in stormy weather they cannot catch fish; and the earth-worms come up on the land when the rain falls. "And I said, Oh, that I had wings like a dove! for then would I fly away, and be at rest."—Psalm lv. Because birds are depressed by an unfavourable change in the atmosphere, and lose those joyful spirits which give rise to their songs. Because the electrical state of the atmosphere has the effect of making them feel uneasy and irritable, and they chase each other about to get rid of the irritability. Because it shows that the indications of unfavourable weather have set in, in the latitudes from which the birds come, and that they have taken an early flight to escape it. Because an east wind is a dry and dense wind, and suitable to the flight of the gossamer spider; the spider feeling instinctively the dryness of the air, throws out its web, and finds it more than usually buoyant upon the dense air. The observation of the changing phenomena which attend the various states of the weather is a very interesting study, though no general rules can be laid down that can be relied upon, because there are modifying circumstances which influence the weather in various localities and climates. To observe weather indications accurately, no phenomenon should be taken alone, but several should be regarded together. The character and the duration of the weather of the preceding days, the direction of the wind, the forms of the clouds, the indications of the barometer, the rise or fall of the thermometer, and the instinctive forewarnings of birds, beasts, insects, and flowers, should all be taken into account. Although no direct material advantages attend such a study, it induces a habit of observation, and develops the inductive faculty of the mind, which, when applied to more significant things, may trace important effects to their greater causes. "Go to the ant, thou sluggard; consider her ways, and be wise."—Prov. vi. |
