An evening red and a morning gray Will set the traveller on his way; But an evening gray and a morning red Will pour down rain on the pilgrim’s head. A greenish color of the sky near to the horizon, often shows that we may expect more wet weather. The most beautiful and varied tints are seen in autumn, and in that season the purple of the falling leaf is often a sign of a continuation of fine weather. When the clouds become more colored than ordinary, and particularly when red prevails, it sometimes indicates an east wind. _Cocks_, when they crow at unwonted hours, often foretell a change of weather. We have often noticed this before rain. But this is by no means so certain a sign as many others; because, at particular seasons, and in particular kinds of weather, cocks habitually crow all day. During the calm, still, dry, dark, and warm weather sometimes occurring in the winter months, and which may be called the halcyon days of our climate, cocks keep a constant crowing all night and day. There appear to be three principal cock crowings in ordinary weather, namely, about midnight or soon after, about three in the morning, and at daybreak; the latter is never omitted. We have noticed, however, that when cocks crow all day, in summer particularly, a change to rain has frequently followed. _Cream and Milk_, when they turn sour in the night, often indicate thereby that thunder storms will probably shortly take place. The effect is referable to the electricity of the air at the time. _Currents of Air_ change their course frequently in the higher regions of the air first, and are afterwards continued to the earth’s surface; hence we can often foresee a change of the wind by observing the way in which the clouds above move. Both the strength of a coming gale, and the point of the compass from which it will blow, may usually be foreseen some time beforehand by noticing the velocity and direction of the clouds floating along in the upper current, or by means of balloons. _Dolphins or porpoises_, when they come about a ship, and sport and gambol on the surface of the water, betoken a storm; hence they are regarded as unlucky omens for sailors. According to ancient fable, they formerly offered themselves in times of storm to convey shipwrecked mariners to the shore; but this is, of course, a story of mere human invention. _Dogs_, before rain, grow sleepy and dull, and lie drowsily before the fire, and are not easily aroused. They also often eat grass, which indicates that their stomachs, like ours, are apt to be disturbed before a change of weather. It is also said to be a sign of change of weather when dogs howl and bark much in the night; they certainly do this much at the full moon, which has given rise to the saying relative to the _dogs that bay at the moon_. Dogs also dig in the earth with their feet before rain, and often make deep holes in the ground.
