There is the conserved force of food. This is found primarily in the grass, the wheat, the rice, the fruit, which grow in our fields and orchards. The lower animals feed on these, and through the process of digestion and assimilation, they are transmuted into blood and bone and muscle—thus furnishing man, who stands at the top and the end of the creative process, with a more refined higher form of food. But whether in the shape of grass, rice, wheat, or in the more refined form of animal flesh, these various elements of food are only so much transmuted sunshine. Before they ever adorned the surface of our fields, or moved in the lowing herd over the meadow, they were held in solution in the sunshine. The food, the fuel, and the animal life of our earth are all traceable to the sun. There is the conserved force of flowing water. This turns the wheel, spins the thread, gins the cotton, weaves the cloth, and grinds the corn. All the force that water possesses for the performance of work, comes from the sun. The warm rays of the sun, coming down on southern seas and rivers, causes the waters thereof to evaporate, and then it is carried on the wings of north-bound winds to a colder clime. There the diffused waters gather themselves into clouds and fall in rain to flow down the rivers, thus exchanging their energy of position, which they have obtained from the sun, for the actual energy of the turning wheel. There is also the conserved force of moving winds. By the aid of this ships spread their sails, and pass from continent to continent with the products of the earth. Again all the force the winds possess for the accomplishment of work comes from the sun. The rays of the sun come down with great intensity upon certain parts of the earth and heat the atmosphere. Into these heated places come the winds from colder regions. Thus currents and counter-currents are created. By putting the wheel of the windmill into these currents this force is converted into the ground wheat and the drawn water. Thus all the different forms of force displayed in the growing forests, the waving harvest fields, the flying birds, the lowing herds, the rushing railway train, the whir of the spindle, the ring of the hammer, and the pulsating blood come directly from the sun. The force, too, seen in all these physical, vegetable, animal, commercial realms, is the exact equivalent of what was poured into them from the sun. The earth contains no other force capital than what was paid over to it by the sun. It has issued no currency of its own, not even enough to run a watch, or to send the blood once around the body, or even to transport a piece of bread to a starving man. All the force our earth possesses is borrowed, and if we were to cease to borrow, we would be bankrupt in a single day. We are to remember, too, that by so much force as the sun has parted with to our earth, and to other worlds which look to it for supplies, by so much has its own force been decreased.
