No force, power, or energy can be produced without their presence.
Our muscular strength, our nervous force, our very thoughts, our imagination, as well as digestion, respiration, circulation of the blood, depend on these elements.
Our sensations, our pleasures, our pains, depend upon them. All the excitement and depression in life are dependent on them.
The beauties of vegetation, all the various shades and colors of flower and blossom, the tints and odors, are dependent on them.
No phenomenon in nature, no matter how terrible, delightful, or enchanting, can be manifested without these elements.
No earthquake, thunder, storm, lightning, wind, hail, rain, snow, or ice could exist without them.
No light, heat, or motion—in fact, none of the physical forces, could be evolved without them.
Our atmosphere, ocean, seas, rivers, forests, are composed of them.
No art, science, mechanics, architecture, nor indeed anything that we now enjoy, could exist without them.
Gunpowder, dynamite, electricity, and all else are dependent on these elements.
