Progress is like the insidious change from youth to old age, except that progress does not mean decay. The change that is almost imperceptible and yet inexorable is much the same, however. You will see a community apparently changeless as the years pass by; and yet, when the years have gone and you look back, there has been a change. It is not the same. It never will be the same. It can pass through further change, but it cannot go back. Men look back sick sometimes with longing for the things that were and that can be no more; they live the old days in memory-but try as they will they may not go back. With intelligent, persistent effort they may retard further change considerably, but that is the most that they can hope to do. Civilization and Time will continue the march in spite of all that man may do.
