AMONG THE FORCES

WHY WRITTEN

Fairies, fays, genii, sprites, etc., were once supposed to be helpful to some favored men. The stories about these imaginary beings have always had a fascinating interest. The most famous of these stories were told at Bagdad in the eleventh century, and were called _The Arabian Nights' Entertainment_. Then men were said to use all sorts of obedient powers, sorceries, tricks, and genii to aid them in getting wealth, fame, and beautiful brides.

But I find the realities of to-day far greater, more useful and interesting, than the imaginations of the past. The powers at work about us are far more kindly and powerful than the Slave of the Ring or of the Lamp.

The object of writing this series of papers about applications of powers to the service of man, their designed king, is manifold. I desire all my readers to see what marvelous provision the Father has made for his children in this their nursery and schoolhouse. He has always been trying to crowd on men more helps and blessings than they were willing to take. From the first mist that went up from the Garden the power of steam has been in every drop of water. Yet men carried their burdens. Since the first storm the swiftness and power of lightning have been trying to startle man into seeing that in it were speed and force to carry his thought and himself. But man still plodded and groaned under loads that might have been lifted by physical forces. I have seen in many lands men bringing to their houses water from the hills in heavy stone jars. Gravitation was meant to do that work, and to make it leap and laugh with pearly spray in every woman's kitchen. The good Father has offered his all-power on all occasions to all men.

I desire that the works of God should keep their designed relation to thought. He says, Consider the lilies; look into the heavens; number the stars; go to the ant; be wise; ask the beasts, the fowl, the fishes; or "talk even to the earth, and it showeth thee."

Every flower and star, rainbow and insect, was meant to be so provocative of thought that any man who never saw a human book might be largely educated. And every one of these thoughts is related to man's best prosperity and joy. He is a most regal king if he achieve the designed dominion over a thousand powerful servitors.

It is well to see that God's present actual powers in full play about us are vastly beyond all the dreams of Arabian imagination. It leads us to expect greater things of him hereafter. That human imagination could so dream is proof of the greatness of its Creator. But that he has actually surpassed those dreams is prophecy of more greatness to come.

I desire that my readers of this generation shall be the great thinkers and inventors of the next. There are amazing powers just waiting to be revealed. Draw aside the curtain. We have not yet learned the A B C of science. We have not yet grasped the scepters of provided dominion. Those who are most in the image and likeness of the Cause of these forces are most likely to do it.


THE MAN WHO NEEDED 452,696 BARRELS OF WATER

A man once had a large field of wheat. He had toiled hard to clear the land, plow the soil, and sow the seed. The crop grew beautifully and was his joy by day and by night. But when it was just ready to head out it suddenly stopped growing for want of moisture. It looked as if all his hard work would be in vain. The poor farmer thought of his wife and children, who were likely to starve in the coming winter. He shed many tears, but they could not moisten one little stalk.

Suddenly he said, "I will water it myself." The field was a mile square, and it needed an inch of water over it all. He quickly figured out that there were 27,878,400 square feet in a square mile. On every twelve square feet a cubic foot of water was needed. A cubic foot of water weighs sixty-two and a third pounds. Hence it would require 74,754 tons of water. To draw this amount 74,754 teams, each drawing a ton, would be required. But they would tramp the wheat all down. Besides, the nearest water in sufficient quantity was the ocean, one thousand miles away over the mountains. It would take three months to make the journey. And, worse than all else, the water of the ocean is so salt that it would ruin the crop.

Alas! there were three impossibilities--so many teams, so many miles, so long time--and two ruins if he could overcome the impossibilities--trampling down the wheat and bringing so much salt. Alas, alas! what could he do but see the poor wheat die of thirst and his poor wife and children die of hunger?

Suddenly he determined to ask the sun to help him. And the sun said he would. That was a very little thing for such a great body to do. So he heated the air over the ocean till it became so thirsty that it drank plenty of water, choosing only the sweet fresh water and leaving all the salt in the ocean. Then the warm air rose, because the heat had expanded it and made it lighter, and the other air rushed down the mountains all over that side of the continent to take its place. Then the warm air went landward in an upper current and carried its load of water in great piles and mountains of clouds; it lifted them over the great ranges of mountains and rained down its thousands of tons of sweet water a thousand miles from the sea, so gently that not a stalk of wheat was trampled down, nor was a single root made acrid by any taste of brine.

Besides the precious drink the sun brought the most delicate food for the wheat. There was carbonic acid, that makes soda water so delicious, besides oxygen, that is so stimulating, nitrogen, ammonia, and half a dozen other things that are so nutritious to growing plants.

Thus the wheat grew up in beauty, headed out abundantly, and matured perfectly. Then the farmer stopped weeping for laughter, and in his joy he remembered to thank, not the sun, nor the wind, but the great One who made them both.


THE SUN'S GREAT HORSES

There was once a man who had thousands of acres of mighty forests in the distant mountains. They were valueless there, but would be exceedingly valuable in the great cities hundreds of miles away, if he could only find any power to transport them thither. So he looked for a team that could haul whole counties of forests so many miles. He saw that the sun drew the greatest loads, and he asked it to help him. And the sun said that was what he was made for; he existed only to help man. He said that he had made those great forests to grow for a thousand years so as to be ready for man when he needed them, and that he was now ready to help move them where they were wanted.

So he told the man who owned the forest that there was a great power, which men called gravitation, that seemed to reside in the center of the earth and every other world, but that it worked everywhere. It held the stones down to the earth, made the rain fall, and water to run down hill; and if the man would arrange a road, so that gravitation and the sun could work together, the forest would soon be transported from the mountains to the sea.

So the man made a trough a great many miles long, the two sides coming together like a great letter V. Then the sun brought water from the sea and kept the trough nearly full year after year. The man put into it the lumber and logs from the great forests, and gravitation pulled the lumber and water ever so swiftly, night and day, miles away to the sea.

How I have laughed as I have seen that perpetual stream of lumber and timber pour out so far from where the sun grew them for man. For the sun never ceased to supply the water, and gravitation never ceased to pull.

This man who relentlessly cut down the great forests never said, "How good the sun is!" nor, "How strong is gravitation!" but said continually, "How smart I am!"


OLD SUN HELP

Holland is a land that is said to draw twenty feet of water. Its surface is below sea level. Since 1440 they have been recovering land from the sea. They have acquired 230,000 acres in all. Fifty years ago they diked off 45,000 acres of an arm of the sea, called Haarlem Meer, that had an average depth of twelve and three quarters feet of water, and proposed to pump it out so as to have that much more fertile land. They wanted to raise 35,000,000 tons of water a month a distance of ten feet, to get through in time. Who could work the handle?

The sun would evaporate two inches a year, but that was too slow. So they used the old force of the sun, reservoired in former ages. Coal is condensed sunshine, still keeping all the old light and power. By a suitable engine they lifted 112 tons ten feet at every stroke, and in 1848, five years after they began to apply old sun force, 41,675 acres were ready for
