As amusement is the object, the plays had better be comedy than tragedy; and no such delicate wordy duels as the "Scrap of Paper," should be attempted, as that requires the highest skill of two great actors.

After reading the part and committing the lines to memory, young actors must submit to many and long rehearsals. After many of these and much study, they must not be discouraged if they grow worse instead of better. Perseverance conquers all things, and at last they reach the dress rehearsal. This is generally a disappointment, and time should be allowed for two dress rehearsals. It is a most excellent and advantageous discouragement, if it leads the actors to more study.

The stage manager has a difficult rôle to play, for he may discover that his actors must change parts. This nearly always excites a wounded self-love, and ill-feeling. But each one should bear in mind that he is only a part of a perfect whole, and be willing to sacrifice himself.

If, however, plays are not successful and cease to amuse, the amateur stage can be utilized for tableaux vivants, which are always pretty, and may be made very artistic. The principle of a picture, the pyramidal form, should be closely observed in a tableau.

There should be a square of black tarletan or gauze nailed before the picture, between the players and the footlights. The drop curtain must be outside of this, and go up and down very carefully, at a concerted signal.

Although the pure white light of candles, or lime light, is the best for such pictures, very pretty effects can be easily made by the introduction of coloured lights, such as are produced by the use of nitrate of strontia, chlorate of potash, sulphuret of antimony, sulphur, oxymuriate of potassa, metallic arsenic, and pulverized charcoal. Muriate of ammonia makes a bluish-green fire, and many colours can be obtained by a little study of chemistry.

To make a red fire, take five ounces of nitrate of strontia dry, and one and a half ounces finely powdered sulphur; also five drachms chlorate of potash, and four drachms sulphuret of antimony. Powder the last two separately in a mortar, then mix them on paper and having mixed the other ingredients, previously powdered, add these last and rub the whole together on paper. To use, mix a little spirits of wine with the powder, and burn in a flat iron plate or pan; the effect is excellent on the picture.

Sulphate of copper when dissolved in water turns it a beautiful blue. The common red cabbage gives three colours. Slice the cabbage and pour boiling water on it. When cold add a small quantity of alum, and you have purple. Potash dissolved in the water will give a brilliant green. A few drops of muriatic acid will turn the cabbage water into crimson. Put these various coloured waters in globes, and with candles behind them they will throw the light on the picture.

Again, if a ghastly look be required, and a ghost scene be in order, mix common salt with spirits of wine in a metal cup, and set it upon a wire frame over a spirit lamp. When the cup becomes heated, and the spirits of wine ignites, the other lights in the room should be extinguished, and that of the spirit lamp hidden from the observer. A light will be produced that will make the players seem like the witches in Macbeth, "that look not like the inhabitants of the earth, but yet are of it."

The burning of common salt produces a very weird effect; for salt has properties other than the conservative, preserving, hospitable qualities which legend and the daily needs of mankind have ascribed to it.
