Men began to see that the operations of Nature were not subject to interference. That eclipses were not caused by the wrath of God--that comets had nothing to do with the destruction of empires or the death of kings, that the stars wheeled in their orbits without regard to the actions of men. In the sacred East the dawn appeared. What have the wordly done? A few years ago a few men became wicked enough to use their senses. They began to look and listen. They began to really see and then they began to reason. They forgot heaven and hell long enough to take some interest in this world. They began to examine soils and rocks. They noticed what had been done by rivers and seas. They found out something about the crust of the earth. They found that most of the rocks had been deposited and stratified in the water--rocks 70,000 feet in thickness. They found that the coal was once vegetable matter. They made the best calculations they could of the time required to make the coal, and concluded that it must have taken at least six or seven millions of years. They examined the chalk cliffs, found that they were composed of the microscopic shells of minute organisms, that is to say, the dust of these shells. This dust settled over areas as large as Europe and in some places the chalk is a mile in depth. This must have required many millions of years. Lyell, the highest authority on the subject, says that it must have required, to cause the changes that we know, at least two hundred million years. Think of these vast deposits caused by the slow falling of infinitesimal atoms of impalpable dust through the silent depths of ancient seas! Think of the microscopical forms of life, constructing their minute houses of lime, giving life to others, leaving their mansions beneath the waves, and so through countless generations building the foundations of continents and islands. Go back of all life that we now know--back of all the flying lizards, the armored monsters, the hissing serpents, the winged and fanged horrors--back to the Laurentian rocks--to the eozoon, the first of living things that we have found--back of all mountains, seas and rivers--back to the first incrustation of the molten world--back of wave of fire and robe of flame--back to the time when all the substance of the earth blazed in the glowing sun with all the stars that wheel about the central fire. Think of the days and nights that lie between!--think of the centuries, the withered leaves of time, that strew the desert of the past! Nature does not hurry. Time cannot be wasted--cannot be lost. The future remains eternal and all the past is as though it had not been--as though it were to be. The infinite knows neither loss nor gain.
