SO few people have any definite idea of the stage behind the scenes, or of the little busy world that congregates there nightly, in the production of a great spectacle like "Undine," requiring all the resources of music, scenery, the drama and the ballet, that, a few evenings since, I conceived it to be my duty to expose myself to demoralization for the public good.

The great public in front of the curtain only see the beautiful effects and the smooth movements, with no idea of the powers that are in exercise and the hidden springs that set at work all this great machinery. I shall not attempt to expose these secrets, but at the same time hope to give you some conception of life on the stage.

Upon expressing my wish to the management to be demoralized for this laudable purpose, they gave me their hearty approval, and on Tuesday night, at half-past seven, I bade good-bye for a brief evening to the great world outside, and passed within the realms of romance, clad in double-proof mail of morality, invulnerable to the combined attacks of naiads, coryphees and Amazons.

Has chaos come again? Will order ever come out of this wilderness of scenes, ropes, weights, pulleys, calcium burners, step ladders, gauze waters, tinseled cars, demon masks, gas tubes, sceptres, levers, crowns, eccentric iron rods, goblets, the fabulous Rhine treasures, tables, lounges, gongs and pistols? What secret charm is to resolve all these into their proper places and make them fill their parts in the production of grace and beauty?

There are few people visible on the stage. Two or three Amazons are sitting on the banquet-table, discussing a question in political economy, as to the relative profit of running sewing-machines and making warlike marches under the Rhine. Two demons are engaged in a friendly game of euchre on the Lurlei Berg, for the stage discipline has not yet commenced. Undoubtedly, after they have accomplished their unearthly mission, and the audience goes home, one of these demons will enjoy stewed oysters and ale in the upper world at the expense of the other. A coryphee is testing her pretty little toes in Sir Hubert's skiff. The seneschal and a scene-shifter are rehearsing Macbeth in the triumphal car which is shortly to ascend to Heaven with Sir Hubert and Undine. There is, as yet, little life on the stage, but it is very busy below in the dressing-rooms. The last stitches are being made, the last touches of rouge—for even the immortals use the same color that flushes the cheeks of Aurelia and Celeste—are being put on. Sir Hubert is cursing his refractory red tights. Undine is in despair over the loss of her crown, which she will find on the stage in the possession of an Amazon, who is strutting the boards for a brief minute as the Water Queen. Kuhleborn is arraying himself in his spotted mail, and the large green-room is swarming with naiads, fays and elves. The bell tinkles for the orchestra. The call-boy rushes down the stairs and cries "All up and dressed for the first act." His voice finds an echo above in the prompter, who shouts "Clear the stage." How that stage was cleared still remains a mystery to me. All the disjecta membra are in place. Outside you hear the overture, and now and then the buzz of the audience; and an inquisitive coryphee, who has cautiously pulled the curtain a trifle aside, informs me that it is a splendid house. The prompter is at the first entrance. The gas man is at the wheels. The property man is everywhere. The scene-shifters are in the wings. Way up in the flies, in a wilderness of ropes, men are taking their places. The calcium men are arranging their reflectors, which will soon flood the stage with their powerful, rich light. The trap men are at their stations. The banquet scene is set. Hubert, Baptiste, the Pilgrim and the Knights are in the narrow space between it and the curtain.

The Water Lily Ballet are in the wings on both sides, rattling away in French and German, standing upon their toes, stretching their limbs and preparing themselves for the dance. Westmael will have a solo, but she looks dejected, faint and spiritless, and a racking cough tells a sad story of the toil and weariness and excitement of the ballet. She is sick to-night. Another leans her head against a side-scene totally unmindful of what is going on in the physical pain she is suffering. Still others look weary and sad-eyed, while some are merry and voluble. But the great audience will know nothing of the aches and pains, the weariness and suffering. The strong will, the excitement and the rivalry will hide all this behind the temporary smile and the coquetry and fascinations of the dance. The ballet-master is hopping about from wing to wing with the proverbial Gallic sprightliness, which will, before the evening is over, change to utter distraction and tearing of hair at the possibility of a faux pas in the ballet or the total depravity of some leading instruments in the orchestra, which will be tearing a rhythm to tatters.

The orchestral prelude ceases. The stage manager casts his quick eye over the stage and gives the word. The gas man turns on the light. The bell tinkles and the curtain rises. While the banquet scene is progressing, the frightful declivity of the Lurlei Berg goes into position, and the gauzy waters of the Rhine are set, across which the moon is sending a tinsel shimmer.

Undine hurries through the wing and mounts to the dizzy height of the Lurlei Berg, in the meantime holding an animated conversation with the young man below, who will gallantly help her down the sloat, below the blue waters of the Rhine, to the Stalactite Cave, which a score of busy hands are already preparing for her reception. A young man in the opposite wing is preparing to play the invisible boatman for Sir Hubert and Baptiste, while I quietly go to the bottom of the Rhine by the down-stairs route, and anticipate the arrival of the trio, who do not express any astonishment whatever at finding me in the Naiad's home, but converse with each other very much in the strain of ordinary mortals.

In the meantime, overhead, the Stalactite Cave is set, and I hear the feet of the ballet dancers skimming over the floor. I get into the outskirts of the Cave by means of the stairs again, meeting a mortal on the way, eating a substantial Spitzenberg, and that Nemesis, the call-boy, in search of some of the Immortals, to find the Water Lily Ballet in full operation. There are no signs of weariness or dejection now. Every face is full of expression. Every limb is posed in elegance. There is pleasure for pain; smiles for dejection; fascination for weariness; coquetry for listlessness; and the Westmael, who looked so sad and weary, is flashing across the stage like a will o' the wisp, compelling, with her wonderful steps upon her toes, her pirouettes and postures, round upon round of applause from the audience, which comes to me behind the scenes like the pattering of rain upon the shingles, what time her rival, Venturola, already dressed for her solo in the Fish Ballet of the next act, is standing near me, closely scrutinizing, with her keen black eyes and nervous manner, every step of her great rival. Westmael comes off, panting like a deer in the chase. All the smiles and fascinations have gone, and in their place the weariness and sadness return to her face, and even Venturola regards her with pity, and the other dancers speak to her in low tones. She passes slowly, almost feebly, to her dressing-room, dropping the bouquet upon the floor which a frantic young man in front, with crimson face, has tossed to her.
