Among the Forces - Henry White Warren (books for 8th graders TXT) 📗

sale and culture.

The water that accumulates now, from rain and infiltration, is lifted out by the sun force as exhibited in wind on windmills. They groaningly work while men sleep.

The Netherlandish engineers are now devising plans to pump out the Zuyder Zee, an area of two thousand square miles. There is plenty of power of every kind for anything, material, mental, spiritual. The problem is the application of it. The thinker is king.

This is only one instance of numberless applications of old sun force. In this country coal does more work than every man, woman, and child in the whole land. It pumps out deep mines, hoists ore to the surface, speeds a thousand trains, drives great ships, in face of waves and winds, thousands of miles and faster than transcontinental trains. It digs, spins, weaves, saws, planes, grinds, plows, reaps, and does everything it is asked to do. It is a vast reservoir of force, for the accumulation of which thousands of years were required.


MOON HELP

At Foo-Chow, China, there is a stone bridge, more than a mile long, uniting the two parts of the city. It is not constructed with arches, but piers are built up from the bottom of the river and great granite stringers are laid horizontally from pier to pier. I measured some of these great stone stringers, and found them to be three feet square and forty-five feet long. They weigh over thirty tons each.

How could they be lifted, handled, and put in place over the water on slender piers? How was it done? There was no Hercules to perform the mighty labor, nor Amphion to lure them to their place with the music of his golden lyre.

Tradition says that the Chinese, being astute astronomers, got the moon to do the work. It was certainly very shrewd, if they did. Why not use the moon for more than a lantern? Is it not a part of the "all things" over which man was made to have dominion?

Well, the Chinese engineers brought the great granite blocks to the bridge site on floats, and when the tide lifted the floats and stones they blocked up the stones on the piers and let the floats sink with the outgoing tide. Then they blocked up the stones on the floats again, and as the moon lifted the tides once more they lifted the stones farther toward their place, until at length the work was done for each set of stones.

Dear, good moon, what a pull you have! You are not merely for the delight of lovers, pleasant as you are for that, but you are ready to do gigantic work.

No wonder that the Chinese, as they look at the solid and enduring character of that bridge, name it, after the poetic and flowery habit of the country, "The Bridge of Ten Thousand Ages."


MORE MOON HELP

Years ago, before there were any railroads, New York city had thousands of tons of merchandise it wished to send out West. Teams were few and slow, so they asked the moon to help. It was ready; had been waiting thousands of years.

We shall soon see that it is easy to slide millions of tons of coal down hill, but how could we slide freight up from New York to Albany?

It is very simple. Lift up the lower end of the river till it shall be down hill all the way to Albany. But who can lift up the end of the river? The moon. It reaches abroad over the ocean and gathers up water from afar, brings it up by Cape Hatteras and in from toward England, pours it in through the Narrows, fills up the great harbor, and sets the great Hudson flowing up toward Albany. Then men put their big boats on the current and slide up the river. Six hours later the moon takes the water out of the harbor and lets other boats slide the other way.

New York itself has made use of the moon to get rid of its immense amount of garbage and sewage. It would soon breed a pestilence, and the city be like the buried cities of old; but the moon comes to its aid, and carries away and buries all this foul breeder of a pestilence, and washes all the harbor and bay with clean floods of water twice a day. Good moon! It not only lights, but works.

The tide in New York Harbor rises only about five feet; up in the Bay of Fundy it ramps, rushes, raves, and rises more than fifty feet high.

In former times men used to put mill wheels into the currents of the tides; when they rushed into little bays and salt ponds they turned the wheels one way; when out, the other.


STAR HELP

"We for whose sake all Nature stands,
And stars their courses move."

Do the stars, that are so far away and seem so small, send us any help? Assuredly. Nothing exists for itself. All is for man.

Magnetism tells the sailor which way he is going. Stars not only do this, when visible, but they also tell just where on the round globe he is. A glance into their bright eyes, from a rolling deck, by an uneducated sailor, aided by the tables of accomplished scholars, tells him exactly where he is--in mid Atlantic, Pacific, Indian, Arctic, or Antarctic Ocean, or at the mouth of the harbor he has sought for months. We lift up our eyes higher than the hills. Help comes from the skies.

This help was started long since, with providential foresight and care. Is he steering by the North Star? A ray of guidance was sent from that lighthouse in the sky half a century before his need, that it might arrive just at the critical time. It has been ever since on its way.

The stars give us, on land and sea, all our reliable standards of time. There is no other source. They are reliable to the hundredth part of a second.

The Italian physicians, in their ignorance of the origin of a disease, named it the influenza, because they imagined that it came from the influence of the stars. No! There is nothing malign in the sweet influences of the Pleiades.

The stars are of special use as a mental gymnasium. On their lofty bars and trapezes the mind can swing itself higher and farther than on any other material thing. Infinity and omnipotence are factors in their problems. They also fill the soul of the rapt beholder with adoring wonder. They are the greatest symbols of the unweariableness of the power and of the minuteness of the knowledge of God. He calleth all their millions by name, and for the greatness of his power not one faileth to come.

Number the stars of a clear Eastern sky, if you are able. So multitudinous and enduring shall the influence of one good man be.


HELP FROM INSENSIBLE SEAS

Suppose one has been at sea a month. He has tacked to every point of the compass, been driven by gales, becalmed in doldrums. At length Euroclydon leaps on him, and he lets her drive. And when for many days and nights neither sun nor stars appear, how can he tell where he is, which way he drives, where the land lies?

There is an insensible ocean. No sense detects its presence. It has gulf streams that flow through us, storms whose waves engulf us, but we feel them not. There are various intensities of its power, the north end of the world not having half as much as the south. There are two places in the north half of the world that have greater intensity than the rest, and only one in the south. It looks as if there were unsoundable depths in some places and shoals in others.

The currents do not flow in exactly the same direction all the time, but their variations are within definite limits.

How shall we detect these steady currents when wind and waves are in tumultuous confusion? They are always present. No winds blow them aside, no waves drench their subtle fire, no mountains make them swerve. But how shall we find them?

Float a bit of magnetic ore in a pail of water, or suspend a bit of magnetized steel by a thread, and these currents make the ore or needle point north and south. Now let waves buffet either side, typhoons roar, and maelstroms whirl; we have, out of the invisible, insensible sea of magnetic influence, a sure and steady guide. Now we can sail out of sight of headlands. We have in the darkness and light, in calm and storm, an unswerving guide. Now Columbus can steer for any new world.

Does not this seem like a spiritual force? Lodestone can impart its qualities to hard steel without the impairment of its own power. There is a giving that does not impoverish, and a withholding that does not enrich.

Wherever there is need there is supply. The proper search with appropriate faculties will find it. There are yet more things in heaven and earth than are dreamed of in our philosophy.


THE FAIRY GRAVITATION

The Germans imagine that they have fairy kobolds, sprites, and gnomes which play under ground and haunt mines. I know a real one. I will give you his name. It is called "Gravitation." The name does not sound any more fairylike than a sledge hammer, but its nature and work are as fairylike as a spider's web. I will give samples of his helpful work for man.

In the mountains about Saltzburg, south of Munich, are great thick beds of solid salt. How can they get it down to the cities where it is needed? Instead of digging it out, and packing it on the backs of mules for forty miles, they turn in a stream of water and make a little lake which absorbs very much salt--all it can carry. Then they lay a pipe, like a fairy railroad, and gravitation carries the salt water gently and swiftly forty miles, to where the railroads can take it everywhere. It goes so easily! There is no railroad to build, no car to haul back, only to stand still and see gravitation do the work.

How do they get the salt and water apart? O, just as easily. They ask the wind to help them. They cut brush about four feet long, and pile it up twenty feet high and as long as they please. Then a pipe with holes in it is laid along the top, the water trickles down all over the loose brush, and the thirsty wind blows through and drinks out most of the water. They might let on the water so slowly that all of it would be drunk out by the wind, leaving the solid salt on the bushes. But they do not want it there. So they turn on so much water that the thirsty wind can drink only the most of it, and the rest drops
