That heat can come directly from the Sun seems an impossibility without some medium of contact, which through the coldness and a barrenness of space does not seem to exist.
As we arrive at certain altitudes in the mountains, we find perpetual snow and ice, and the same class of atmosphere is encountered anywhere else rising in a balloon to similar heights. It would be natural to expect an increasing warmth as we get away from the Earth toward the Sun, but the reverse being the case, it is hard to imagine what the temperature of space 1,000 miles away must be.
The question is likely to be asked, if the Sun does not send out heat, how is it obtained?
The answer will be in accordance with the first proposition in this brief work. All heat is obtained by Friction, in absence of which there can be no heat. The Earth gets its heat mostly by friction through its atmosphere.
The mass of atmosphere surrounding our planet is like an ocean made up of gases and elements that produce both water and land. The revolution of the Earth through that atmosphere at the rate of 1,000 miles an hour, seventeen miles a minute, or nearly four miles every second, is something as incomprehensible to our minds as the distance to the Sun. Only for this friction for a certain distance from the surface, the same condition of cold would no doubt exist on the surface as on the tops of the high ranges of mountains.
The Earth is producing its own warmth by friction in its atmosphere the same as a wagon-wheel would do by being rapidly revolved inside of a loose tire. The atmosphere is virtually a tire surrounding us, through which the Earth revolves, and by Friction produces the warmth as really as a man warms his hands by rubbing them together.
That the Sun can be an inconsumable body of fire, or that it can become extinct is a most preposterous belief.
That the Sun is a vast body of earth and water hardly admits of a doubt, and its warmth and light is due to the same influence largely that the Earth and every other planet experiences.
There is not and cannot be a complete consumption of material in the immutable affairs of Nature, as there must be an eternal and exhaustless interchange of supply and demand. While our forest and other fuel supply is being burned, another is growing and something forming to keep up the balance.
In Nature nothing is lost, neither can there be increase; design is limitless, and resources inexhaustible; duplicates are never known in form, species, features, and thoughts; thus showing one of Nature’s most positive laws, that mankind shall not accept one central thought, creed, or purpose to be universally followed, as such an order of things would entirely preclude the writing of the few hints herein offered, as the encouragement of any new device for man’s benefit of body or mind, thus leaving everything in a state of stagnation wherein thrift, learning, and progress would be unknown.
