It has always struck me that the phrase, "There is a time for all things," had a wider meaning than we usually attach to it. I think that the seed of all discoveries, past and present, was scattered ages ago--perhaps at the very creation of the world--in the mind of man; that when it had rested there long enough, and the season of its ripening came, up grew the stalk and the ear, and the harvest was gathered, and mankind garnered it up as a provision for them and their heirs for ever. The sense of beauty lay for generation and generation, germinating in the intellects and hearts of men; and, when the time came, a whole harvest of it was gathered at one time in the statues and pictures and temples of ancient Greece. But it was only the greater and more flourishing portion of the increase that grew in that birth-place of gods and heroes. The seed was scattered over a wider surface; and, if we could recover proofs of it, I should not at all fear to bet you two half-pints to one, that there were sculptors and painters in Asia and in Egypt, equal, in their several manners, to Phidias and Apelles. When printing, in the same way, had lain in furrow the proper time, the first blades of it began to appear in many regions at the same period. With steam it is the same; and, when the next invention is brought into practical use, it will be found that the thought of it had agitated hundreds of minds by the Rhine, by the Thames, by the Hudson, and perhaps by the sacred Ganges, or the still more sacred Nile.
