This is good literature, and worthy the great poet; the science of it I would not be so willing to vouch for.

The poets, more perhaps than the scientists, have illustrated and held by the great law of alternation, of ebb and flow, of turn and return, in nature. An equilibrium, or, what is the same thing, a straight line, Nature abhors more than she does a vacuum. If the moisture of the air were uniform, or the heat uniform, that is, in equilibrio, how could it rain? what would turn the scale? But these things are heaped up, are in waves. There is always a preponderance one way or the other; always “a steep inequality.” Down this incline the rain comes, and up the other side it goes. The high barometer travels like the crest of a sea, and the low barometer like the trough. When the scale kicks the beam in one place, it is correspondingly depressed in some other. When the east is burning up, the west is generally drowning out. The weather, we say, is always in extremes; it never rains but it pours: but this is only the abuse of a law on the part of the elements which is at the bottom of all the life and motion on the globe.

The rain itself comes in shorter or longer waves,—now fast, now slow—and sometimes in regular throbs or pulse-beats. The fall and winter rains are, as a rule, the most deliberate and general, but the spring and summer rains are always more or less impulsive and capricious. One may see the rain stalking across the hills or coming up the valley in single file, as it were. Another time it moves in vast masses or solid columns, with broad open spaces between. I have seen a spring snowstorm lasting nearly all day that swept down in rapid intermittent sheets or gusts. The waves or pulsations of the storm were nearly vertical and were very marked. But the great fact about the rain is that it is the most beneficent of all the operations of nature; more immediately than sunlight even, it means life and growth. Moisture is the Eve of the physical world, the soft teeming principle given to wife to Adam or heat, and the mother of all that lives. Sunshine abounds everywhere, but only where the rain or dew follows is there life. The earth had the sun long before it had the humid cloud, and will doubtless continue to have it after the last drop of moisture has perished or been dissipated. The moon has sunshine enough, but no rain; hence it is a dead world—a lifeless cinder. It is doubtless true that certain of the planets, as Saturn and Jupiter, have not yet reached the condition of the cooling and ameliorating rains, while in Mars vapor appears to be precipitated only in the form of snow; he is probably past the period of the summer shower. There are clouds and vapors in the sun itself,—clouds of flaming hydrogen and metallic vapors, and a rain every drop of which is a burning or molten meteor. Our earth itself has doubtless passed through the period of the fiery and consuming rains. Mr. Proctor thinks there may have been a time when its showers were downpourings of “muriatic, nitric, and sulphuric acid, not only intensely hot, but fiercely burning through their chemical activity.” Think of a dew that would blister and destroy like the oil of vitriol! but that period is far behind us now. When this fearful fever was past and the earth began to “sweat;” when these soft, delicious drops began to come down, or this impalpable rain of the cloudless nights to fall,—the period of organic life was inaugurated. Then there was hope and a promise of the future. The first rain was the turning-point, the spell was broken, relief was at hand. Then the blazing furies of the fore world began to give place to the gentler divinities of later times.

The first water,—how much it means! Seven tenths of man himself is water. Seven tenths of the human race rained down but yesterday! It is much more probable that Alexander will flow out of a bung-hole than that any part of his remains will ever stop one. Our life is indeed a vapor, a breath, a little moisture condensed upon the pane. We carry ourselves as in a phial. Cleave the flesh, and how quickly we spill out! Man begins as a fish, and he swims in a sea of vital fluids as long as his life lasts. His first food is milk; so is his last and all between. He can taste and assimilate and absorb nothing but liquids. The same is true throughout all organic nature. ’Tis water-power that makes every wheel move. Without this great solvent, there is no life. I admire immensely this line of Walt Whitman’s:—

“The slumbering and liquid trees.”

The tree and its fruit are like a sponge which the rains have filled. Through them and through all living bodies there goes on the commerce of vital growth, tiny vessels, fleets and succession of fleets, laden with material bound for distant shores, to build up, and repair, and restore the waste of the physical frame.

Then the rain means relaxation; the tension in Nature and in all her creatures is lessened. The trees drop their leaves, or let go their ripened fruit. The tree itself will fall in a still, damp day, when but yesterday it withstood a gale of wind. A moist south wind penetrates even the mind and makes its grasp less tenacious. It ought to take less to kill a man on a rainy day than on a clear. The direct support of the sun is withdrawn; life is under a cloud; a masculine mood gives place to something like a feminine. In this sense, rain is the grief, the weeping of Nature, the relief of a burdened or agonized heart. But tears from Nature’s eyelids are always remedial and prepare the way for brighter, purer skies.

I think rain is as necessary to the mind as to vegetation. Who does not suffer in his spirit in a drought and feel restless and unsatisfied? My very thoughts become thirsty and crave the moisture. It is hard work to be generous, or neighborly, or patriotic in a dry time, and as for growing in any of the finer graces or virtues, who can do it? One’s very manhood shrinks, and, if he is ever capable of a mean act or of narrow views, it is then.

Oh, the terrible drought! When the sky turns to brass; when the clouds are like withered leaves; when the sun sucks the earth’s blood like a vampire; when rivers shrink, streams fail, springs perish; when the grass whitens and crackles under your feet; when the turf turns to dust; when the fields are like tinder; when the air is the breath of an oven; when even the merciful dews are withheld, and the morning is no fresher than the evening; when the friendly road is a desert, and the green woods like a sick-chamber; when the sky becomes tarnished and opaque with dust and smoke; when the shingles on the houses curl up, the clapboards warp, the paint blisters, the joints open; when the cattle rove disconsolate and the hive-bee comes home empty; when the earth gapes and all nature looks widowed, and deserted, and heart-broken,—in such a time, what thing that has life does not sympathize and suffer with the general distress?

The drought of the summer and early fall of 1876 was one of those severe stresses of weather that make the oldest inhabitant search his memory for a parallel. For nearly three months there was no rain to wet the ground. Large forest trees withered and cast their leaves. In spots, the mountains looked as if they had been scorched by fire. The salt sea-water came up the Hudson ninety miles, when ordinarily it scarcely comes forty. Toward the last, the capacity of the atmosphere to absorb and dissipate the smoke was exhausted, and innumerable fires in forests and peat-swamps made the days and the weeks—not blue, but a dirty yellowish white. There was not enough moisture in the air to take the sting out of the smoke, and it smarted the nose. The sun was red and dim even at midday, and at his rising and setting he was as harmless to the eye as a crimson shield or a painted moon. The meteorological conditions seemed the farthest possible remove from those that produce rain, or even dew. Every sign was negatived. Some malevolent spirit seemed abroad in the air, that rendered abortive every effort of the gentler divinities to send succor. The clouds would gather back in the mountains, the thunder would growl, the tall masses would rise up and advance threateningly, then suddenly cower, their strength and purpose ooze away; they flattened out; the hot, parched breath of the earth smote them; the dark, heavy masses were re-resolved into thin vapor, and the sky came through where but a few moments before there had appeared to be deep behind deep of water-logged clouds. Sometimes a cloud would pass by, and one could see trailing beneath and behind it a sheet of rain, like something let down that did not quite touch the earth, the hot air vaporizing the drops before they reached the ground.
