The encroachments of Slavery upon our national policy have been like those of a glacier in a Swiss valley. Inch by inch, the huge dragon with his glittering scales and crests of ice coils itself onward, an anachronism of summer, the relic of a bygone world where such monsters swarmed. But it has its limit, the kindlier forces of Nature work against it, and the silent arrows of the sun are still, as of old, fatal to the frosty Python. Geology tells us that such enormous devastators once covered the face of the earth, but the benignant sunlight of heaven touched them, and they faded silently, leaving no trace but here and there the scratches of their talons, and the gnawed boulders scattered where they made their lair. We have entire faith in the benignant influence of Truth, the sunlight of the moral world, and believe that slavery, like other worn-out systems, will melt gradually before it.
