In almost any position you can imagine the Earth to revolve around the Sun, one of these sides or ends must be partially and at times wholly exposed to the Sun’s rays, and the effect, it seems natural to suppose, would make the interior horizons light as the exterior. The water, it is believed, on any body acts as a reflector and is a giver of light from every planetary body in some degree. It is all gas, to talk about the gaseous condition and nature of the Sun, and “other worlds than ours.” They would at best be a very poor investment and not worth the labor and genius of a power able to create; 160 acres of good land in any productive locality would be worth more than 1,000 such whirling pyrotechnics of space. It is altogether too presumptive to suppose that our little Earth with all its boasted cities, and boroughs thrown in, can be the only habitation for poor, vain and sinful man. XV. METEORS. These are nothing more or less than dust particles thrown from volcanic eruptions on some planet, and in countless numbers drifting through time and space till sucked into the atmosphere of some other orb. Whoever doubts the influence of friction ought to be convinced by watching these meteoric specks falling through our atmosphere of a clear evening, although the process goes on as much in day as night time. While falling in space this dust must gain an inconceivable speed, as a feather without resistance falls as rapidly as a ball of lead. The contact with our atmosphere ignites and evidently consumes them into gas before reaching the Earth. They used to be called falling stars, but if they were of inferior magnitude it is quite probable there would have been many a badly bumped head before this time, from the numbers that have fallen. XVI. ATTRACTION OF GRAVITATION. This seems to be a question not fully settled by sufficient authority. It seems as if this term were incorrectly applied and that suction would be a better name for the agency. That bodies fall to the ground when dropped, or return when thrown or shot into the air is nothing more than a stick of wood thrown into a stream floats with the current and drifts to the bank. Most people when asked which side of a fan you feel the air from, when fanning yourself, naturally reply from the side toward you, but by trying the experiment you will soon discover that the air comes after the passage of the fan, only filling the space or vacuum the fan has made. It has often been asked why people trying to board a train in motion are so apt to be drawn under the wheels, and legs and arms crushed. It is the same reason as with the fan, a large vacuum is being produced and proportionate suction occurs to fill it.
