CHAPTER XLIX.

OSCILLATING THROUGH SPACE.--EARTH'S SHELL ABOVE ME.[14]

[14] For detail illustration of the earth shell, as explained in

this chapter, see the plate.

Continued my companion:

"We have just now crossed the line of gravitation. We were drawn

downward until at a certain point, to which I called your attention at

the time, we recently crossed the curved plane of perfect rest, where

gravity ceases, and by our momentum are now passing beyond that plane,

and are now pressing against the bond of gravitation again. This shell

in which gravity centers is concentric with that of the earth's

exterior, and is about seven hundred miles below its surface. Each

moment of time will now behold us carried farther from this sphere of

attraction, and thus the increasing distance increases the force of the

restraining influence. Our momentum is thus retarded, and consequently

the rapidity of our motion is continually decreasing. At last when the

forces of gravitation and mass motion neutralize each other, we will

come to a state of rest again. When our motion in this direction ceases,

however, gravitation, imperishable, continues to exert its equalizing

influence, the result being a start in the opposite direction, and we

will then reverse our course, and retrace our path, crossing again the

central band of attraction, to retreat and fly to the opposite side of

the power of greater attraction, into the expanse from which we came,

and that is now above us."

"Can this oscillation ever end? Are we to remain thus, as an unceasing

pendulum, traversing space, to and fro across this invisible shell of

attraction from now until the end of time?"

"No; there are influences to prevent such an experience; one being the

friction of the attenuated atmosphere into which we plunge each time

that we cross the point of greater gravity, and approach the crust of

the earth. Thus each succeeding vibration is in shorter lines, and at

last we will come to a state of perfect rest at the center of gravity."

"I can only acquiesce in meek submission, powerless even to argue, for I

perceive that the foundations for my arguments must be based on those

observed conditions of natural laws formerly known to me, and that do

not encompass us here; I accept, therefore, your statements as I have

several times heretofore, because I can not refute them. I must close my

eyes to the future, and accept it on faith; I cease to mourn the past, I

can not presage the end."

"Well spoken," he replied; "and while we are undergoing this necessary

delay, this oscillating motion, to which we must both submit before we

can again continue our journey, I will describe some conditions inherent

in the three spheres of which the rind of the earth is composed, for I

believe that you are now ready to receive and profit by facts that

heretofore you would have rejected in incredulity.

"The outer circle, coat, or contour, of which you have heard others

besides myself speak, is the surface crust of our globe, the great

sphere of land and water on which man is at present an inhabitant. This

is the exposed part of the earth, and is least desirable as a residence.

It is affected by grievous atmospheric changes, and restless physical

conditions, such as men, in order to exist in, must fortify against at

the expense of much bodily and mental energy, which leads them,

necessarily, to encourage the animal at the expense of the ethereal. The

unmodified rays of the sun produce aerial convulsions that are marked by

thermal contrasts, and other meteorological variations, during which the

heat of summer and the cold of winter follow each other periodically and

unceasingly. These successive solar pulsations generate winds, calms,

and storms, and in order to protect himself against such exposures and

changes in material surroundings, man toils, suffers, and comes to

believe that the doom, if not the object, of life on earth is the

preservation of the earthy body. All conditions and phases of nature on

this outer crust are in an angry struggle, and this commotion envelops

the wretched home, and governs the life of man. The surrounding cyclones

of force and matter have distorted the peaceful side of what human

nature might be until the shortened life of man has become a passionate,

deplorable, sorrowful struggle for physical existence, from the cradle

to the grave. Of these facts man is practically ignorant, although each

individual is aware he is not satisfied with his condition. If his

afflictions were obvious to himself, his existence would be typical of a

life of desolation and anguish. You know full well that the condition of

the outer sphere is, as I have described it, a bleak, turbulent surface,

the roof of the earth on which man exists, as a creeping parasite does

on a rind of fruit, exposed to the fury of the ever-present earth

storms.

"The central circle, or medial sphere, the shell, or layer of

gravitation, lies conformably to the outer configuration of the globe,

about seven hundred miles towards its center. It stretches beneath the

outer circle (sphere) as a transparent sheet, a shell of energy, the

center of gravitation. The material crust of the earth rests on this

placid sphere of vigor, excepting in a few places, where, as in the

crevice we have entered, gaps, or crevices, in matter exist, beginning

from near the outer surface and extending diagonally through the medial

and inner spheres into the intra-earth space beyond. This medial sphere

is a form of pure force, a disturbance of motion, and although without

weight it induces, or conserves, gravity. It is invisible to mortal

eyes, and is frictionless, but really is the bone of the earth. On it

matter, the retarded energy of space, space dust, has arranged itself as

dust collects on a bubble of water. This we call matter. The material

portion of the earth is altogether a surface film, an insignificant skin

over the sphere of purity, the center of gravitation. Although men

naturally imagine that the density and stability of the earth is

dependent on the earthy particles, of which his own body is a part, such

is not the case. Earth, as man upon the outer surface, can now know it,

is an aggregation of material particles, a shell resting on this

globular sphere of medial force, which attracts solid matter from both

the outer and inner surfaces of earth, forming thereby the middle of the

three concentric spheres. This middle sphere is the reverse of the

outer, or surface, layer in one respect, for, while it attracts solids,

gases are repelled by it, and thus the atmosphere becomes less dense as

we descend from the outer surfaces of the earth. The greater degree of

attraction for gases belongs, therefore, to the earth's exterior

surface."

"Exactly at the earth's exterior surface?" I asked.

"Practically so. The greatest density of the air is found a few miles

below the surface of the ocean; the air becomes more attenuated as we

proceed in either direction from that point. Were this not the case, the

atmosphere that surrounds the earth would be quickly absorbed into its

substance, or expand into space and disappear."

"Scientific men claim that the atmosphere is forty-five geographical

miles in depth over the earth's surface," I said.

"If the earth is eight thousand miles in diameter, how long would such

an atmosphere, a skin only, over a great ball, resist such attraction,

and remain above the globe? Were it really attracted towards its center

it would disappear as a film of water sinks into a sponge."

"Do you know," I interrupted, "that if these statements were made to men

they would not be credited? Scientific men have calculated the weights

of the planets, and have estimated therefrom the density of the earth,

showing it to be solid, and knowing its density, they would, on this

consideration alone, discredit your story concerning the earth shell."

[Illustration: THE EARTH AND ITS ATMOSPHERE.

The space between the inner and the outer lines represents the

atmosphere upon the earth. The depth to which man has penetrated the

earth is less than the thickness of either line, as compared with the

diameter of the inner circle.]

"You mistake, as you will presently see. It is true that man's ingenuity

has enabled him to ascertain the weights and densities of the planets,

but do you mean to say that these scientific results preclude the

possibility of a hollow interior of the heavenly bodies?"

"I confess, I do."

"You should know then, that what men define as density of the earth, is

but an average value, which is much higher than that exhibited by

materials in the surface layers of the earth crust, such as come within

the scrutiny of man. This fact allows mortals of upper earth but a vague

conjecture as to the nature of the seemingly much heavier substances

that exist in the interior of the earth. Have men any data on hand to

show exactly how matter is distributed below the limited zone that is

accessible to their investigations?"

"I think not."

"You may safely accept, then, that the earth shell I have described to

you embraces in a compact form the total weight of the earth. Even

though men take for granted that matter fills out the whole interior of

our planet, such material would not, if distributed as on earth's

surface, give the earth the density he has determined for it."

"I must acquiesce in your explanations."

"Let us now go a step further in this argument. What do you imagine is

the nature of those heavier substances whose existence deep within the

earth is suggested by the exceedingly high total density observed by man

on upper earth?"

"I am unable to explain, especially as the materials surrounding us

here, seemingly, do not differ much from those with which my former life

experience has made me acquainted."

"Your observation is correct, there is no essential difference in this

regard. But as we are descending into the interior of this globe, and

are approaching the central seat of the shell of energy, the opposing

force into which we plunge becomes correspondingly stronger, and as a

consequence, matter pressed within it becomes really lighter. Your own

experience about your weight gradually disappearing during this journey

should convince you of the correctness of this fact."

"Indeed, it does," I admitted.

"You will then readily understand, that the heavy material to which

surface-bred mortals allude as probably constituting the interior of the

earth, is, in fact, nothing but the manifestation of a matter-supporting

force, as exemplified in the sphere of attractive energy, the seat of

which we are soon to encounter on our journey. Likewise the mutual

attraction of the heavenly bodies is not a property solely of their

material part, but an expression in which both the force-spheres and the

matter collected thereon take part.

"Tell me more of the sphere in which gravitation is intensest."

"Of that you are yet to judge," he replied. "When we come to a state of

rest in the stratum of greater gravity, we will then traverse this

crevice in the sheet of energy until we reach the edge of the earth

crust, after which we will ascend towards the interior of the earth,

until we reach the inner crust, which is, as before explained, a surface

of matter that lies conformably with the external crust of the earth,

and which is the interior surface of the solid part of the earth. There

is a concave world beneath the outer convex world."

"I can not comprehend you. You speak of continuing our journey towards

the center of the earth, and at the same time you say that after leaving

the Median Circle, we will then ascend, which seems contradictory."

"I have endeavored to show you that matter is resting in or on a central

sphere of energy, which attracts solid bodies towards its central plane.

From this fundamental and permanent seat of gravity we may regard our

progress as up-hill, whether we proceed towards the hollow center or

towards the outer surface of the globe. If a stick weighted on one end

is floated upright in water, an insect on the top of the stick above the

water will fall to the surface of the liquid, and yet the same insect

will rise to the surface of the water if liberated beneath the water at

the bottom of the stick. This comparison is not precisely applicable to

our present position, for there is no change in medium here, but it may

serve as an aid to thought and may indicate to you that which I wish to

convey when I say 'we ascend' in both directions as we pull against

Gravity. The terms up and down are not absolute, but relative."

Thus we continued an undefined period in mind conversation; and of the

information gained in my experience of that delightful condition, I have

the privilege now to record but a small portion, and even this statement

of facts appears, as I glance backward into my human existence, as if it

may seem to others to border on the incredible. During all that time--I

know not how long the period may have been--we were alternately passing

and repassing through the partition of division (the sphere of gravity)

that separated the inner from the outer substantial crust of earth. With

each vibration our line of travel became shorter and shorter, like the

decreasing oscillations of a pendulum, and at last I could no longer

perceive the rushing motion of a medium like the air. Finally my guide

said that we were at perfect rest at a point in that mysterious medial

sphere which, at a distance of about seven hundred miles below the level

of the sea, concentrates in its encompassing curvature, the mighty power

of gravitation. We were fixed seven hundred miles from the outer surface

of the globe, but more than three thousand from the center.
