seemed imminent, they would suddenly undergo a change that looked like curdling, and when clouds do that no rain need be expected. Time and again I saw their continuity broken up, saw them separate into small masses,--in fact saw a process of disintegration and disorganization going on, and my hope of rain was over for that day. Vast spaces would be affected suddenly; it was like a stroke of paralysis: motion was retarded, the breeze died down, the thunder ceased, and the storm was blighted on the very threshold of success.
I suppose there is some compensation in a drought; Nature doubtless profits by it in some way. It is a good time to thin out her garden, and give the law of the survival of the fittest a chance to come into play. How the big trees and big plants do rob the little ones! there is not drink enough to go around, and the strongest will have what there is. It is a rest to vegetation, too, a kind of torrid winter that is followed by a fresh awakening. Every tree and plant learns a lesson from it, learns to shoot its roots down deep into the perennial supplies of moisture and life.
But when the rain does come, the warm, sun-distilled rain; the far- traveling, vapor-born rain; the impartial, undiscriminating, unstinted rain; equable, bounteous, myriad-eyed, searching out every plant and every spear of grass, finding every hidden thing that needs water, falling upon the just and upon the unjust, sponging off every leaf of every tree in the forest and every growth in the fields; music to the ear, a perfume to the smell, an enchantment to the eye; healing the earth, cleansing the air, renewing the fountains; honey to the bee, manna to the herds, and life to all creatures,--what spectacle so fills the heart? "Rain, rain, O dear Zeus, down on the plowed fields of the Athenians, and on the plains."
There is a fine sibilant chorus audible in the sod, and in the dust of the road, and in the porous plowed fields. Every grain of soil and every root and rootlet purrs in satisfaction, Because something more than water comes down when it rains; you cannot produce this effect by simple water; the good-will of the elements, the consent and approbation of all the skyey influences, come down; the harmony, the adjustment, the perfect understanding of the soil beneath and the air that swims above, are implied in the marvelous benefaction of the rain. The earth is ready; the moist winds have wooed it and prepared it, the electrical conditions are as they should be, and there are love and passion in the surrender of the summer clouds. How the drops are absorbed into the ground! You cannot, I say, succeed like this with your hose or sprinkling-pot. There is no ardor or electricity in the drops, no ammonia, or ozone, or other nameless properties borrowed from the air.
Then one has not the gentleness and patience of Nature; we puddle the ground in our hurry, we seal it up and exclude the air, and the plants are worse off than before. When the sky is overcast and it is getting ready to rain, the moisture rises in the ground, the earth opens her pores and seconds the desire of the clouds.
Indeed, I have found there is but little virtue in a sprinkling-pot after the drought has reached a certain pitch. The soil will not absorb the water. 'Tis like throwing it on a hot stove. I once concentrated my efforts upon a single hill of corn and deluged it with water night and morning for several days, yet its leaves curled up and the ears failed the same as the rest. Something may be done, without doubt, if one begins in time, but the relief seems strangely inadequate to the means often used. In rainless countries good crops are produced by irrigation, but here man can imitate in a measure the patience and bounty of Nature, and, with night to aid him, can make his thirsty fields drink, or rather can pour the water down their throats.
I have said the rain is as necessary to man as to vegetation. You cannot have a rank, sappy race, like the English or the German, without plenty of moisture in the air and in the soil. Good viscera and an abundance of blood are closely related to meteorological conditions, unction of character, and a flow of animal spirits, too; and I suspect that much of the dry and rarefied humor of New England, as well as the thin and sharp physiognomies, are climatic results. We have rain enough, but not equability of temperature or moisture,--no steady, abundant supply of humidity in the air. In places in Great Britain it is said to rain on an average three days out of four the year through; yet the depth of rainfall is no greater than in this country, where it rains but the one day out of four. John Bull shows those three rainy days both in his temper and in his bodily habit; he is better for them in many ways, and perhaps not quite so good in a few others: they make him juicy and vascular, and maybe a little opaque; but we in this country could well afford a few of his negative qualities for the sake of his stomach and full-bloodedness.
We have such faith in the virtue of the rain, and in the capacity of the clouds to harbor and transport material good, that we more than half believe the stories of the strange and anomalous things that have fallen in showers. There is no credible report that it has ever yet rained pitchforks, but many other curious things have fallen. Fish, flesh, and fowl, and substances that were neither, have been picked up by veracious people after a storm. Manna, blood, and honey, frogs, newts, and fish-worms, are among the curious things the clouds are supposed to yield. If the clouds scooped up their water as the flying express train does, these phenomena could be easier explained. I myself have seen curious things. Riding along the road one day on the heels of a violent summer tempest, I saw the ground swarming with minute hopping creatures. I got out and captured my hands full. They proved to be tree-toads, many of them no larger than crickets, and none of them larger than a bumblebee. There seemed to be thousands of them. The mark of the tree-toad was the round, flattened ends of their toes. I took some of them home, but they died the next day. Where did they come from? I imagined the violent wind swept them off the trees in the woods to windward of the road. But this is only a guess; maybe they crept out of the ground, or from under the wall near by, and were out to wet their jackets.
I have never yet heard of a frog coming down chimney in a shower. Some circumstantial evidence may be pretty conclusive, Thoreau says, as when you find a trout in the milk; and if you find a frog or toad behind the fire-board immediately after a shower, you may well ask him to explain himself.
When I was a boy I used to wonder if the clouds were hollow and carried their water as in a cask, because had we not often heard of clouds bursting and producing havoc and ruin beneath them? The hoops gave way, perhaps, or the head was pressed out. Goethe says that when the barometer rises, the clouds are spun off from the top downward like a distaff of flax; but this is more truly the process when it rains. When fair weather is in the ascendant, the clouds are simply reabsorbed by the air; but when it rains, they are spun off into something more compact: 't is like the threads that issue from the mass of flax or roll of wool, only here there are innumerable threads, and the fingers that hold them never tire. The great spinning-wheel, too, what a humming it makes at times, and how the footsteps of the invisible spinner resound through the cloud-pillared chambers!
The clouds are thus literally spun up into water; and were they not constantly recruited from the atmosphere as the storm-centre travels along,--was new wool not forthcoming from the white sheep and the black sheep that the winds herd at every point,--all rains would be brief and local; the storm would quickly exhaust itself, as we sometimes see a thunder-cloud do in summer. A storm will originate in the far West or Southwest--those hatching-places of all our storms--and travel across the continent, and across the Atlantic to Europe, pouring down incalculable quantities of rain as it progresses and recruiting as it wastes. It is a moving vortex, into which the outlying moisture of the atmosphere is being constantly drawn and precipitated. It is not properly the storm that travels, but the low pressure, the storm impulse, the meteorological magnet that makes the storm wherever its presence may be. The clouds are not watering-carts, that are driven all the way from Arizona or Colorado to Europe, but growths, developments that spring up as the Storm-deity moves his wand across the land. In advance of the storm, you may often see the clouds grow; the condensation of the moisture into vapor is a visible process; slender, spiculæ-like clouds expand, deepen, and lengthen; in the rear of the low pressure, the reverse process, or the wasting of the clouds, may be witnessed. In summer, the recruiting of a thunder-storm is often very marked. I have seen the clouds file as straight across the sky toward a growing storm or thunder-head in the horizon as soldiers hastening to the point of attack or defense. They would grow more and more black and threatening as they advanced, and actually seemed to be driven by more urgent winds than certain other clouds. They were, no doubt, more in the line of the storm influence. All our general storms are cyclonic in their character, that is, rotary and progressive. Their type may be seen in every little whirlpool that goes down the swollen current of the river; and in our hemisphere they revolve in the same direction, namely, from right to left, or in opposition to the hands of a watch. When the water finds an outlet through the bottom of a dam, a suction or whirling vortex is developed that generally goes round in the same direction. A morning-glory or a hop-vine or a pole-bean winds around its support in the same course, and cannot be made to wind in any other. I am aware there are some perverse climbers among the plants that persist in going around the pole in the other direction. In the southern hemisphere the cyclone revolves in the other direction, or from left to right. How do they revolve at the equator, then? They do not revolve at all. This is the point of zero, and cyclones are never formed nearer than the third parallel of latitude. Whether hop-vines also refuse to wind about the pole there I am unable to say.
All our cyclones originate in the far Southwest and travel northeast. Why did we wait for the Weather Bureau to tell us this fact? Do not all the filmy, hazy, cirrus and cirro-stratus clouds first appear from the general direction of the sunset? Who ever saw them pushing their opaque filaments over the sky from the east or north? Yet do we not have "northeasters" both winter and summer? True, but the storm does not come from that direction. In such a case we get that segment of the cyclonic whirl. A northeaster in one place may be an easter, a norther, or a souther in some other locality. See through those drifting, drenching clouds that come hurrying out of the northeast, and there are the boss-clouds above them, the great captains themselves, moving serenely on in the opposite direction.
Electricity is, of course, an important agent in storms. It is the great organizer and ring-master. How a clap of thunder will shake down the rain! It gives the clouds a smart rap; it jostles the vapor so that the particles fall together more quickly; it makes the drops let go in double and treble ranks. Nature likes to be helped in that way,--likes to have the water agitated when she is freezing it or heating it, and the clouds smitten when she is compressing them into rain. So does a shock of surprise quicken the pulse in man, and in the crisis of action help him to a decision.
What a spur and impulse the summer shower is! How its coming quickens and hurries up the slow, jogging country life! The traveler along the dusty road arouses from his reverie at the warning rumble behind the hills; the children hasten from the field or from the school; the farmer steps lively and thinks fast. In the hay-field, at the first signal-gun of the elements, what a commotion! How the horserake rattles, how the pitchforks fly, how the white sleeves play and twinkle in the sun or against the dark background of the coming storm! One man does the work of two or three. It is a race with the elements, and the
