The night comes for the purpose of checking our busy employment, and introducing an interval of repose between the links of our action and our aspiration. It draws its dim curtain around the field of toil. It buries the objects of our handiwork in darkness, and involves them with uncertainty. It comes to the relief of the exhausted body and the tired brain. Our powers, harmonizing with the diurnal revolutions of the earth, fail with the failing light, and a merciful Providence casts around us this mantle of shadow, and snatches us from our occupation.
