There are probably but few who will dissent from this decision; and we will add, that in our opinion, a preservation so extraordinary, exclusive of a Providential interposition which some will think they discern in it, affords an argument for manual labor schools, or physical education, more pointed, and perhaps conclusive, than all which this indefatigable agent has said himself, or gleaned from the testimony of others, although this composes an amount of evidence of the most convincing kind. In the report alluded to, the Agent himself observes that "God has revealed his will to man upon the subject of education. It is written in the language of nature, and can be understood without a commentary. This revelation consists in the universal consciousness of those influences which body and mind exert upon each other--influences innumerable, incessant, and all-controlling; the body continually modifying the state of the mind, and the mind ever varying the condition of the body. "Every man who has marked the reciprocal action of body and mind, surely need not be told that mental and physical training should go together. Even the slightest change in the condition of the body often produces an effect upon the mind so sudden and universal, as to seem almost miraculous. The body is the mind's palace; but darken its windows, and it is a prison. It is the mind's instrument; sharpened, it cuts keenly--blunted, it can only bruise and disfigure. It is the mind's reflector; if bright, it flashes day--if dull, it diffuses twilight. It is the mind's servant; if robust, it moves with swift pace upon its errands--if a cripple, it hobbles on crutches. We attach infinite value to the mind, and justly; but in this world, it is good for nothing without the body. Can a man think without the brain?--can he feel without nerves?--can he move without muscles? The ancients were right in the supposition that an unsound body is incompatible with a sound mind. [They looked only for the _mens sana in corpore sano_.] He who attempts mental effort during a fit of indigestion, will cease to wonder that Plato located the soul in the stomach. A few drops of water upon the face, or a feather burnt under the nostril of one in a swoon, awakens the mind from its deep sleep of unconsciousness. A slight impression made upon a nerve often breaks the chain of thought, and the mind tosses in tumult. Let a peculiar vibration quiver upon the nerve of hearing, and a tide of wild emotion rushes over the soul. The man who can think with a gnat in his eye, or reason while the nerve of a tooth is twinging, or when his stomach is nauseated, or when his lungs are oppressed and laboring; he who can give wing to his imagination when shivering with cold, or fainting with heat, or worn down with toil, can claim exemption from the common lot of humanity.
