The average quantity of aqueous vapour, or water held in the air, is estimated to be 54,460,000,000,000 tons. The annual amount of rainfall is estimated to be 186,240 cubic miles. If this rain were at any one moment equally spread over the land portion of the globe, it would cover all the continents with water three feet deep. Reflect now that water in its natural state is 773 times heavier than air. And now suppose that you had never heard or conceived of the principle of evaporation, and that you were required to lift up this vast mass of 54,460,000,000,000 tons of water one mile, two, three, four or five miles high into the air, and keep it suspended there. Well, what man, or all mankind combined cannot do, or begin to do, God did on that second day of creation, and does daily. Water as vapour occupies 1600 times larger space than water as liquid. Hence, water as vapour is lighter than air, and naturally ascends. That is the whole secret. How manifold are the works of God. (G. D. Boardman.)
