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.
