Nations burn with internal fire of thought and affection, which wastes while it works. We shall find finer combustion and finer fuel. Intellect is a fire: rash and pitiless it melts this wonderful bone-house which is called man. Genius even, as it is the greatest good, is the greatest harm. Whilst all thus burns, — the universe in a blaze kindled from the torch of the sun, — it needs a perpetual tempering, a phlegm, a sleep, atmospheres of azote, deluges of water, to check the fury of the conflagration; a hoarding to check the spending, a centripetence equal to the centrifugence; and this is invariably supplied.
The railroad dirt-ears are good excavators, but there is no porter like Gravitation, who will bring down any weights which man cannot carry, and if he wants aid, knows where to find his fellow laborers. Water works in masses, and sets its irresistible shoulder to your mills or your ships, or transports vast boulders of rock in its iceberg a thousand miles. But its far greater power depends on its talent of becoming little, and entering the smallest holes and pores. By this agency, carrying in solution elements needful to every plant, the vegetable world exists.
But as I said, we must not paint the farmer in rose-color. Whilst these grand energies have wrought for him and made his task possible, he is habitually engaged in small economies, and is taught the power that lurks in petty things. Great is the force of a few simple arrangements; for instance, the powers of a fence. On the prairie you wander a hundred miles and hardly find a stick or a stone. At rare intervals a thin oak-opening has been spared, and every such section has been long occupied. But the farmer manages to procure wood from far, puts up a rail-fence, and at once the seeds sprout and the oaks rise. It was only browsing and fire which had kept them down. Plant fruit-trees by the roadside, and their fruit will never be allowed to ripen. Draw a pine fence about them, and for fifty years they mature for the owner their delicate fruit. There is a great deal of enchantment in a chestnut rail or picketed pine boards.
Nature suggests every economical expedient somewhere on a great scale. Set out a pine-tree, and it dies in the first year, or lives a poor spindle. But Nature drops a pine-cone in Mariposa, and it lives fifteen centuries, grows three or four hundred feet high, and thirty in diameter, — grows in a grove of giants, like a colonnade of Thebes. Ask the tree how it was done. It did not grow on a ridge, but in a basin, where it found deep soil, cold enough and dry enough for the pine; defended itself from the sun by growing in groves, and from the wind by the walls of the mountain. The roots that shot deepest, and the stems of happiest exposure, drew the nourishment from the rest, until the less thrifty perished and manured the soil for the stronger, and the mammoth Sequoias rose to their enormous proportions. The traveller who saw them remembered his orchard at home, where every year, in the destroying wind, his forlorn trees pined like suffering virtue. In September, when the pears hang heaviest and are taking from the sun their gay colors, comes usually a gusty day which shakes the whole garden and throws down the heaviest fruit in bruised heaps. The planter took the hint of the Sequoias, built a high wall, or — better — surrounded the orchard with a nursery of birches and evergreens. Thus he had the mountain basin in miniature; and his pears grew to the size of melons, and the vines beneath them ran an eighth of a mile. But this shelter creates a new climate. The wall that keeps off the strong wind keeps off the cold wind. The high wall reflecting the heat back on the soil gives that acre a quadruple share of sunshine, —
“Enclosing in the garden squareA dead and standing pool of air,”and makes a little Cuba within it, whilst all without is Labrador.
The chemist comes to his aid every year by following out some new hint drawn from nature, and now affirms that this dreary space occupied by the farmer is needless; he will concentrate his kitchen-garden into a box of one or two rods square, will take the roots into his laboratory; the vines and stalks and stems may go sprawling about in the fields outside, he will attend to the roots in his tub, gorge them with food that is good for them. The smaller his garden, the better he can feed it, and the larger the crop.
