The gigantic springs of the country that have not been caught in any of the great natural basins are mostly confined to the limestone region of the Middle and Southern States,—the valley of Virginia and its continuation and deflections into Kentucky, Tennessee, northern Alabama, Georgia, and Florida. Through this belt are found the great caves and the subterranean rivers. The waters have here worked like enormous moles, and have honeycombed the foundations of the earth. They have great highways beneath the hills. Water charged with carbonic acid gas has a very sharp tooth and a powerful digestion, and no limestone rock can long resist it. Sherman's soldiers tell of a monster spring in northern Alabama,—a river leaping full-grown from the bosom of the earth; and of another at the bottom of a large, deep pit in the rocks, that continues its way under ground.

There are many springs in Florida of this character, large underground streams that have breathing-holes, as it were, here and there. In some places the water rises and fills the bottoms of deep bowl-shaped depressions; in other localities it is reached through round natural well-holes; a bucket is let down by a rope, and if it becomes detached is quickly swept away by the current. Some of the Florida springs are perhaps the largest in the world, affording room and depth enough for steamboats to move and turn in them. Green Cove Spring is said to be like a waterfall reversed; a cataract rushing upward through a transparent liquid instead of leaping downward through the air. There are one or two of these enormous springs also in northern Mississippi,—springs so large that it seems as if the whole continent must nurse them.

The Valley of the Shenandoah is remarkable for its large springs. The town of Winchester, a town of several thousand inhabitants, is abundantly supplied with water from a single spring that issues on higher ground near by. Several other springs in the vicinity afford rare mill-power. At Harrisonburg, a county town farther up the valley, I was attracted by a low ornamental dome resting upon a circle of columns, on the edge of the square that contained the court-house, and was surprised to find that it gave shelter to an immense spring. This spring was also capable of watering the town or several towns; stone steps led down to it at the bottom of a large stone basin. There was a pretty constant string of pails to and from it. Aristotle called certain springs of his country "cements of society," because the young people so frequently met there and sang and conversed; and I have little doubt this spring is of like social importance. There is a famous spring at San Antonio, Texas, which is described by that excellent traveler, Frederick Law Olmsted. "The whole river," he says, "gushes up in one sparkling burst from the earth, with all the accessories of smaller springs,—moss, pebbles, foliage, seclusion, etc. Its effect is overpowering. It is beyond your possible conception of a spring."

Of like copiousness and splendor is the Caledonia spring, or springs, in western New York. They give birth to a white-pebbled, transparent stream, several rods wide and two or three feet deep, that flows eighty barrels of water per second, and is alive with trout. The trout are fat and gamy even in winter.

The largest spring in England, called the Well of St. Winifred, at Holywell, flows less than three barrels per second. I recently went many miles out of my way to see the famous trout spring in Warren County, New Jersey. This spring flows about one thousand gallons of water per minute, which has a uniform temperature of fifty degrees winter and summer. It is near the Musconetcong Creek, which looks as if it were made up of similar springs. On the parched and sultry summer day upon which my visit fell, it was well worth walking many miles just to see such a volume of water issue from the ground. I felt with the boy Petrarch, when he first beheld a famous spring, that "were I master of such a fountain I would prefer it to the finest of cities." A large oak leans down over the spring and affords an abundance of shade. The water does not bubble up, but comes straight out with great speed, like a courier with important news, and as if its course underground had been a direct and an easy one for a long distance. Springs that issue in this way have a sort of vertebra, a ridgy and spine-like centre that suggests the gripe and push there is in this element.

What would one not give for such a spring in his back yard, or front yard, or anywhere near his house, or in any of his fields? One would be tempted to move his house to it, if the spring could not be brought to the house. Its mere poetic value and suggestion would be worth all the art and ornament to be had. It would irrigate one's heart and character as well as his acres. Then one might have a Naiad Queen to do his churning and to saw his wood; then one might "see his chore done by the gods themselves," as Emerson says, or by the nymphs, which is just as well.

I know a homestead, situated on one of the picturesque branch valleys of the Housatonic, that has such a spring flowing by the foundation walls of the house, and not a little of the strong overmastering local attachment that holds the owner there is born of that, his native spring. He could not, if he would, break from it. He says that when he looks down into it he has a feeling that he is an amphibious animal that has somehow got stranded. A long, gentle flight of stone steps leads from the back porch down to it under the branches of a lofty elm. It wells up through the white sand and gravel as through a sieve, and fills the broad space that has been arranged for it so gently and imperceptibly that one does not suspect its copiousness until he has seen the overflow. It turns no wheel, yet it lends a pliant hand to many of the affairs of that household. It is a refrigerator in summer and a frost-proof envelope in winter, and a fountain of delights the year round. Trout come up from the Weebutook River and dwell there and become domesticated, and take lumps of butter from your hand, or rake the ends of your fingers if you tempt them. It is a kind of sparkling and ever-washed larder. Where are the berries? where is the butter, the milk, the steak, the melon? In the spring. It preserves, it ventilates, it cleanses. It is a board of health and a general purveyor. It is equally for use and for pleasure. Nothing degrades it, and nothing can enhance its beauty. It is picture and parable, and an instrument of music. It is servant and divinity in one. The milk of forty cows is cooled in it, and never a drop gets into the cans, though they are plunged to the brim. It is as insensible to drought and rain as to heat and cold. It is planted upon the sand, and yet it abideth like a house upon a rock. It evidently has some relation to a little brook that flows down through a deep notch in the hills half a mile distant, because on one occasion, when the brook was being ditched or dammed, the spring showed great perturbation. Every nymph in it was filled with sudden alarm and kicked up a commotion.

In some sections of the country, when there is no spring near the house, the farmer, with much labor and pains, brings one from some uplying field or wood. Pine and poplar logs are bored and laid in a trench, and the spring practically moved to the desired spot. The ancient Persians had a law that whoever thus conveyed the water of a spring to a spot not watered before should enjoy many immunities under the state, not granted to others.

Hilly and mountainous countries do not always abound in good springs. When the stratum is vertical, or has too great a dip, the water is not collected in large veins, but is rather held as it falls, and oozes out slowly at the surface over the top of the rock. On this account one of the most famous grass and dairy sections of New York is poorly supplied with springs. Every creek starts in a bog or marsh, and good water can be had only by excavating.

What a charm lurks about those springs that are found near the tops of mountains, so small that they get lost amid the rocks and debris and never reach the valley, and so cold that they make the throat ache! Every hunter and mountain-climber can tell you of such, usually on the last rise before the summit is cleared. It is eminently the hunter's spring. I do not know whether or not the foxes and other wild creatures lap at it, but their pursuers are quite apt to pause there to take breath or to eat their lunch. The mountain-climbers in summer hail it with a shout. It is always a surprise, and raises the spirits of the dullest. Then it seems to be born of wildness and remoteness, and to savor of some special benefit or good fortune. A spring in the valley is an idyl, but a spring on the mountain is a genuine lyrical touch. It imparts a mild thrill; and if one were to call any springs "miracles," as the natives of Cashmere are said to regard their fountains, it would be such as these.
