BY REV. S. W. FISHER. I have presupposed three things in reference to education. The field which it covers is also three-fold--the body, the intellect, and the heart. The body is the living temple of the soul. It is more than a casket for the preservation of the jewel; it is more than the setting of the diamond; it is more even than an exquisitely-constructed dwelling wherein the soul lives, and works and worships. It is a living, sensitive agent, into which the spirit pours its own life, through which it communes with all external nature, and receives the effluxes of God streaming from a material creation. It is the admirable organ through which the man sends forth his influence either to bless and vivify, or to curse and wither. By it, the immortal mind converts deserts into gardens, creates the forms of art, sways senates, and sheds its plastic presence over social life. The senses are the finely-wrought gates through which knowledge enters the sublime dome of thought; while the eye, the tongue, the hand, are the instruments of the Spirit's power over the outer world. The soul incarnate in such a body, enjoys a living medium of reciprocal communication between itself and all things without. Meanwhile the body itself does not arrive here mature in its powers; nor does it spring suddenly from the imbecility of the infant to the strength of the man. By slow development, by a gradual growth, in analogy with that of a tree whose life is protracted, it rises, after years of existence, to its appointed stature. Advancing thus slowly, it affords ample time for its full and free development.
