"To tread the same dull circle round and round;"-- The parson often discourses touching the round of his parochial duties; and who does not sympathize with the diurnal editor at the thought of the harassing duties devolving upon him, "in circles incessant." The man of the world, and the sensualist, dance the giddy round of pleasure. The judge goes his circuit, to bring men to justice in this world, and the self-denying missionary traverses his, to save them from it in the next. It is very true that the periphery of the circles traversed by some persons and objects, is greater than that of others. One man walks the circumference of his duties in a single day; another in a week; while it may require the whole life of the third to perform the journey. Many members of Congress make speeches in circles, whether arguing abstruse points of constitutional law, or the claims of a party candidate; as do lawyers their cases at the bar, proving the foregoing proposition by the following, and inferring the following from the foregoing. Cast a stone into a lake or a mill-pond, and it will produce a succession of motions, circle following circle in order, and extending the radius until they disappear in the distance. The political movements of nations are circular. Under the severe pressure of despotism the people rise in their fury, and snap their chains asunder. A republic follows; degenerating first into a rude and wild democracy; and thence into a cruel and more turbulent anarchy. As a relief from the evils of this, the people, sighing for repose, fly back again into the arms of despotism. But with a people who have once tasted the sweets of liberty, this kind of tranquillity is short. Maddened by wrongs, real or supposed, they are soon prepared again to rush into the death-dance of revolution. The "one eternal principle" of the Chinese, forming "the first link in the great material chain" of their system, is represented by a circle. Time wings his flight in circles, and every year rolls round within itself. Hence the poets sing of "the circling years." The sun turns round upon his own axis; and the moon "changes monthly in her circled orb." The other celestial bodies all wheel their courses in circles around the common centre. The moons of Jupiter revolve around him in circles, and he carries them along with him in his periodical circuit round the sun. Saturn always moves within his rings, and thus adorned himself, walks in circles through the regions of space:-- "And other planets circle other suns."
