You are early in the woods. Nature's children are not yet astir. The silence is profound; but it is a fruitful, uplifting silence. There are no sounds to strike the most delicate strings in that wondrous harp of your inner ear. But if your spiritual ear is attentive you should catch those forest voices that fall softer than silence and speak of peace and purity, truth and beauty.
Soon the silence is broken. Curiously, the first sound you hear comes from advanced civilization, the rumble of a train fifteen miles away. On a still morning like this one can hardly stand five full minutes on any spot in the whole state of Iowa without hearing the sound of a train. There are no more trackless prairies, no more terrors of blizzards. Pioneer days have passed away. The railroads have brought security, comfort, prosperity, intelligence, and the best of the world's work, physical and mental, fresh at the door every morning.
Whirr! There goes a ruffed grouse from the snow, scarce a rod ahead. In a moment, up goes another. Too bad to rout them from their bed under the roots of a fallen tree. Farther on a rabbit scurries from another log. There is his "form" fresh in the snow.
The river, away down below, begins to boom and crack. The ice is like the tight head of a big bass drum, but the drummer is inside and the sound comes muffled. The frost is the peg which tightens all the strings of earth and makes them vibrant. The tinkle of sleigh bells on the wagon road fully a mile away comes with peculiar clearness.
When the sun is more than half way from the horizon to the meridian, Nature begins to wake up. A chickadee emerges from his hole in the decaying trunk of a red oak and cheeps softly as he flies to the branch of a slippery elm. His merry "chick-a-dee-dee-dee-dee" brings others of his race, and away they all go down to the red birches on the river bottom. The metallic quanks of a pair of nuthatches call attention to the upper branches of a big white oak. A chickadee and one of the nuthatches see a tempting morsel at the same time. A spiteful peck from nuthatch leaves him master of the morsel and the field. But the chickadee does not care. He flies down and spies a stalk of golden-rod above the snow on which there is a round object looking like a small onion. Chickadee doesn't know that this is the spherical gall of the trypeta solidaginis, but he does know that it contains a fat white grub. He knows, too, that there is a beveled passage leading to a cell in the center and that the outer end of this passage is protected by a membrane window. After some balancing and pirouetting he smashes the window with his bill, runs his long tongue down the passageway, gulps the grub and away he flies to join his comrades down in the birches, chirping gaily as he goes.
Downy woodpecker "pleeks" his happiness as he excavates the twig of a silver maple. Probably he has found the larvæ which the wood wasp left there in the fall. The big hairy woodpecker flies across the clearing with a strident scream. Next to the crow and the jay he is the noisiest fellow in the winter woods. He hammers away at a decaying basswood and the chips which fall are an inch and a half long. His hammering is almost as loud as the bark of a squirrel in the trees across the river. The blood-red spot on the back of his head has an exquisite glow in the sunshine, and you get a fine look at it, for he is busily working little more than a rod from where you stand. He does wonderful work with that strong bill. One decaying basswood found recently was eighteen inches in diameter and the woodpeckers had drilled big holes clear through it. The pile of their chips at the base would have filled a bushel basket.
By the time you have reached the spring the woods are full of life and sound, and the spring itself adds to the winter music. The rocks where it bubbles out are thickly covered with hoar frost. One of the big blocks of limestone in its causeway is covered with ice, clear and viscid as molten glass. The river is bridged over with ice twenty inches thick, save only the little gulf stream into which the spring pours its waters. From the surface of this stream thin smoky wreaths of vapor rise and are changed into crystals by the frosty air. But the waters of the spring gush forth as abundantly and musically now as they did in the hot days of last July, and the clam-shell with which you then drank is still in its place by the rock. The pure, melodious, beautiful spring makes its own environment, regardless of surroundings. Its sources are in the unfailing hills. It suggests the lives of some men and women whose friendship you enjoy, and who are ever ready to refresh you on life's way.
The wind of last night has carried much of the snow over the top of the ridge and deposited it in this sheltered slope of the river cañon. Here are wind-formed caves of sculptured snow, vaulted with a tender blue. Turrets and towers sparkle in the splendid light. All angles are softened, and everywhere the lines of the snow curves are smooth and flowing. The drift sweeps down from the footpath way on the river bank to the ice-bound bed of the river in graceful lines. Where the side of the cañon is more precipitous there is equal beauty. Each shrub has its own peculiar type amidst the broken drift. The red cedar, which is Iowa's nearest approach to a pine, except in a few favored counties, hangs from the top of the crag heavily festooned with feathery snow. Those long creeping lines on which the crystals sparkle are only brambles, and that big rosette of rusty red and fluffy white is the New Jersey tea. Those spreading, pointed fingers of coral with a background of dazzling white are the topmost twigs of the red osier dogwood. The strip of shrubs with graceful spray, now bowed in beauty by the river's brink, is a group of young red birches, and this bunch of downy brown twigs, two feet above the snow, sparkling with frost particles, is the downy viburnum. The great tangle of vine and lace work mixed with snow is young hop hornbeam, supporting honeysuckle.
