The oceans, seas and lakes contain water enough to cover the entire surface of the earth to a depth of six hundred feet, if the earth's surface were actually round.
In huge reservoirs, which we call oceans, the earth's waters are stored for our use. Those vast volumes of water rest on the surface of a whirling sphere travelling through space at fearful speed. The slightest derangement, the slightest lack of balance in our motion round the sun, the slightest shifting of the poles, and mountains of water miles high would sweep over the continents and wipe out—not only one small city—but the entire human race. ——
Our existence here requires a precision so great that our minds can but feebly grasp it. Change the temperature of your body by but a few degrees and you die. But you travel through space safely, with a freezing ocean of ether about you. You travel in company with suns that throw out endless billions of degrees of heat. You are protected in a travelling hothouse, regulated exactly to suit your feeble strength and all your wants. ——
Did you ever see the small, black nose of a pug dog pressed against the window of a flying express train?
Have you ever seen that pug barking at the landscape whirling by?
Have you ever reflected on the utter inability of that pug to realize the marvellous intelligence and power that are whirling him along as he barks and wags his tail and enjoys himself calmly?
Kind reader, you and all of us, whirling along in this magnificently conducted express train called the earth—whirling onward to a destiny worthy of our habitation—are so many poor little pug dogs looking out at nature's marvels and looking out with less than pug-dog appreciation.
THE EARTH IS ONLY A FRONT YARD
The philosophers, political economists, lawmakers, editors, sociologists, and all the other would-be deep thinkers of this earth, are really engaged in a pretty small business.
We are like a swarm of human beings cast away on some desert island. This earth is our island, a little island in space, and it is a desert island and a badly arranged island in more ways than one. Many of us lack good dwellings, some of us lack food, all of us are worried about the future. The island is infested with mosquitoes and with diseases that we have not learned to conquer. There are many criminals on it that prey upon the honest people—criminals at the top and criminals at the bottom of society.
