And still there came that silver tone From the shrivelled lips of the toothless crone, (Let me never forget till my dying day The tone or the burden of her lay,) "Passing away! passing away!” LESSON CXLIV. That Silent Moon. GEORGE W. DOANE. THAT silent moon, that silent moon, Have passed beneath her placid eye, How oft has Guilt's unhallowed hand, Profaned her pure and holy light! But dear to her, in summer eve, By rippling wave, or tufted grove, Dispersed along the world's wide way, When friends are far, and fond ones rove, How powerful she to wake the thought, How powerful, too, to hearts that mourn, ― And oft she looks, that silent moon, On couch, whence pain has banished sleep: O, softly beams her gentle eye On those who mourn, and those who die. But beam on whomsoe'er she will, And fall where'er her splendors may, There's pureness in her chastened light, There's comfort in her tranquil ray: What power is hers to soothe the heart What power, the trembling tear to start! The dewy morn let others love, Or bask them in the noontide ray; 35* LESSON CXLV. The Midnight Mail. HANNAH F. GOULD. "Tis midnight—all is peace profound! They come they pause a moment - when, Hast thou a parent far away' ? Who shared thine infant glee? If aught like these, then thou must feel That strings thy heart, till morn appears, Perhaps thy treasure 's in the deep, Thy parent's hoary head no more Thy son from out the wave! - nor death restore Thy prattler's tongue perhaps is stilled; May be, the home where all thy sweet And while, alternate o'er my soul Till morn shall bring relief, LESSON CXLVI. The Progress of Knowledge. S. G. GOODRICH CONTEMPLATE for a moment the progress of science within the last forty years. Geology has almost entirely grown up within the present century. All former ages had dozed in ignorance and indifference over its mighty revelations. The bones of the mastodon and the ichthyosaurus had been occasionally discovered, and some dreaming philosophers had wondered whence they came; but the knowledge of whole races of animals and vegetables, that lived, and flourished, and perished on this earth before the creation of man, and the existence of the present order of things, of long ages that rolled over the world before any being was here to record its history, — of great revolutions which rent the granite ribs of the earth, like shreds, and fires that dissolved mountains as in the crucible of a chemist; — all these facts, now indisputably established, are the discoveries — the revelations — of our own day. In mineralogy, chemistry, natural history, and natural philosophy, there has been an almost entire revolution. Old theories have become exploded, old errors abandoned, and philosophy founded on facts has become established. And two things are here specially to be remarked. Philosophy, before a sealed book to all but the learned, is now as familiar as household goods. Philosophy is no longer hidden within a sanctuary, to which a privileged class only are admitted; but the doors are thrown wide to the world, and whosoever will, may enter in and partake of its privileges. Science is not only familiar, but it is rendered practical and useful by application to the arts of life. Chemistry is no longer the mystery of the alchemist, nor the black art of the juggler. It is no longer the perquisite of the scholar nor the plaything of universities. It is in our schools and academies, it is in our workshops, — in the hands of mechanics and farmers, practical men, who are every day turning it to practical account. Mankind had before enslaved the horse and the ox, and taught them to toil in his service; they had before taught the rivers to turn the wheel of the mill, the waters to bear the ships, and the winds to speed them on their way; but it is within the present century that Philosophy has been chained to the car of human art, and been made to work for the comfort and pleasure of man. Philosophy, forty years ago a proud, privileged thing, the tool and instrument of the |
