Equally vain is the hammer of vociferation, unless the matter is brought home with warmth into our hearts. We have often sought to produce effect, and to influence our hearers, much as though the smith merely put the iron in fire, and barely warmed it; it is contrary to the nature of things to use the hammer while the material is not duly tempered. Thus I have frequently, brother, found myself in preaching. You have, above, the mystery of all effective speaking, in Parliament, at the bar, and in the pulpit; remembering the difference in the subjects, and the sources of heat. In the pulpit, we speak of the deep things of God; and we are to pray for, and to expect warmth from the Divine Spirit. You complain that you cannot get your voice into a manageable key, and yet to speak with liveliness and power. Many, with a bad voice, well-governed, have become powerful speakers; while others, with a good voice, have, in consequence of not mastering a natural key, and not being able to move themselves, been most ineffective speakers. I would direct you to fix your voice at its natural pitch, which you may easily do; you may then, with facility, raise and lower it according to the subject in hand. If you commence in too high a key, you cannot keep it up long. First, you cannot modulate it as the occasion may require; and you fall into an unpliable, tedious monotony, and all natural cadence, and emphasis is lost. Without attuning the voice into the natural key, effective oratory is impossible. Secondly, remember, not to speak in your throat, or nostrils. If the former, you must soon become hoarse, and harsh loudness follows; the glory and vivacity are then departed, and instead of facility and cheerfulness, you have the roarings of death—the breath failing, with forced screams, and harsh whisperings. Thirdly, raise your voice to the roof of your mouth; do not close your teeth against it, neither imprison it in the nostrils, but open your mouth naturally, and keep your voice within your lips, where it will find room enough to play its high, and its low intonations, to discourse its flats, and sharps, to utter its joys, and sorrows. When you thus have your voice under control, instead of you being under its control, dragging you about in all disorder, you will find it your servant, running upon your errands, up and down, all through the camp, alternating in energy, and pliability, to the end of the sermon; and not becoming cold and weak, scarcely bearing you through, like Bucephalus, Alexander the Great’s horse, which, mortally wounded, just brought his master out of the battle, and then expired. Fourthly, remember, not to press too much upon your breath, when you have attained the natural use of it, by using very long sentences,
