Effective means were afterwards taken to detect the minute incipient pimples with which the disease was always ushered in, and never afterwards was it allowed to reach serious proportions. It was destroyed in its earliest germ, and thus much power and vitality and thousands of lives were saved to the State.

THE HARP.

"Music….the emanation of the concentrated light of the soul….The language of the angels."

The harp is our principal musical instrument. We have one that is portable and in form like a lyre; but our great harp is much larger than yours, differently constructed, and far more effective, combining, as it does, in its tones all the delicacy, expression, and oneness of a single executant, with the brilliancy and power of a combined body of performers.

It rests on a ball firmly placed on a massive pedestal, which is easily moved from one place to another by means of small wheels. The ball on which the harp rests revolves in a socket, so that the instrument can easily be placed in the position the performer desires, and then, by means of a bolt, fixed firmly in its place. No support from the executant is needed. The harp does not rest upon him in any way, and he has, at the same time, entire power over every part.

The instrument is divided into fourths, that is, into four sets of chords. The first only of these four sets is touched by the player, but on any of the first set being intoned, each corresponding string of the three other sets, all of which are stouter and more powerful than the set played upon, resounds in harmony.

The power given out by the three sets of strings is proportioned to the sound produced on the first set by the performer, as the force of an echo is stronger or weaker according as the sound producing it is increased or diminished in volume.

In the framework of the harp there are conducting strings of electricity, which unite all the rest with the first set and with each other. The electricity is generated by a liquid contained in a small tube, and is set in motion by the movement of the strings of the first set of chords. The tube can be placed in or removed from the instrument with the greatest ease; without it, the first set alone responds to the player's touch.

The musician has the power of varying and depressing the notes of the instrument in a marvellous manner, so as to produce instantaneously the most delicate or the most powerful sounds, with endless modulations and variety of tone. I have heard echoes and responses given out as though the music had been breathed from a great distance;—the gentlest whispers were alternated with all the force of a band of music.
