have been explained so easily at first would now be as difficult of explanation, At last she was in the great public vestibule, which she was now visiting for the third time, and of which, at her last visit, she had taken the bearings accurately. The door was there—closed, indeed, but it opened f to the hand, the hall and on e stairs and o n g the passages there had been gas, but here there was no light beyond that given by the little taper which she carried. When accompanied by the porter she had not feared the darkness, but now there was something in the obscurity which made her dread to walk the length of the room up to the mustard jar. She paused, and listened, and trembled. Then she thought of the glories of Thompson Hall, of the genial warmth of a British Christmas, of that proud legislator who was her first cousin, and with a rush she made good the distance, and laid her hand upon the copious delf. She looked round, but there was no one there; no sound was heard; not the distant creak of a shoe, not a rattle from one of those thousand doors. As she paused with her fair hand upon the top of the jar, while the other held the white cloth on which the medicinal compound was to be placed, she looked like Lady Macbeth as she listened at Duncan’s chamber door.

There was no doubt as to the sufficiency of the contents. The jar was full nearly up to the lips. The mixture was, no doubt, very different from that good, wholesome English mustard which your cook makes fresh for you, with a little water, in two minutes. It was impregnated with a sour odor, and was, to English eyes, unwholesome of color. But still it was mustard. She seized the horn spoon, and without further delay spread an ample sufficiency on the folded square of the handkerchief. Then she commenced to hurry her return.

But still there was a difficulty, no thought of which had occurred to her before. The candle occupied one hand, so that she had but the other for the sustenance of her treasure. Had she brought a plate or saucer from the salon, it would have been all well. As it was, she was obliged to keep her eye intent on her right hand, and to proceed very slowly on her return journey. She was surprised to find what an aptitude the thing had to slip from her grasp. But still she progressed slowly, and was careful not to miss a turning. At last she was safe at her chamber door. There it was, No. 333.

CHAPTER II.
MRS. BROWN’S FAILURE.

With her eye still fixed upon her burden, she glanced up at the number of the door—333. She had been determined all through not to forget that. Then she turned the latch and crept in. The chamber also was dark after the gaslight on the stairs, but that was so much the better. She herself had put out the two candles on the dressing-table before she had left her husband. As she was closing the door behind her she paused, and could hear that he was sleeping. She was well aware that she had been long absent—quite long enough for a man to fall into slumber who was given that way. She must have been gone, she thought, fully an hour. There had been no end to that turning over of napkins which she had so well known to be altogether vain. She paused at the centre-table of the room, still looking at the mustard, which she now delicately dried from off her hand. She had had no idea that it would have been so difficult to carry so light and so small an affair. But there it was, and nothing had been lost. She took some small instrument from the washing-stand, and with the handle collected the flowing fragments into the centre. Then the question occurred to her whether, as her husband was sleeping so sweetly, it would be well to disturb him. She listened again, and felt that the slight murmur of a snore with which her ears were regaled was altogether free from any real malady in the throat. Then it occurred to her that, after all, fatigue perhaps had only made him cross. She bethought herself how, during the whole journey, she had failed to believe in his illness. What meals he had eaten! How thoroughly he had been able to enjoy his full complement of cigars! And then that glass of brandy, against which she had raised her voice slightly in feminine opposition. And now he was sleeping there like an infant, with full, round, perfected, almost sonorous workings of the throat. Who does not know that sound, almost of two rusty bits of iron scratching against each other, which comes from a suffering windpipe? There was no semblance of that here. Why disturb him when he was so thoroughly enjoying that rest which, more certainly than anything else, would fit him for the fatigue of the morrow’s journey?

I think that, after all her labor, she would have left the pungent cataplasm on the table and have crept gently into bed beside him, had not a thought suddenly struck her of the great injury he had been doing her if he were not really ill. To send her down there, in a strange hotel, wandering among the passages, in the middle of the night, subject to the contumely of any one who might meet her, on a commission which, if it were not sanctified by absolute necessity, would be so thoroughly objectionable! At this moment she hardly did believe that he had ever really been ill. Let him have the cataplasm; if not as a remedy, then as a punishment. It could, at any rate, do him no harm. It was with an idea of avenging rather than of justifying the past labors of the night that she proceeded at once to quick action.

Leaving the candle on the table, so that she might steady her right hand with the left, she hurried stealthily to the bedside. Even though he was behaving badly to her, she would not cause him discomfort by waking him roughly. She would do a wife’s duty to him as a British matron should. She would not only put the warm mixture on his neck, but would sit carefully by him for twenty minutes, so that she might relieve him from it when the proper period should have come for removing the counter-irritation from his throat. There would doubtless be some little difficulty in this—in collecting the mustard after it had served her purpose. Had she been at home, surrounded by her own comforts, the application would have been made with some delicate linen bag, through which the pungency of the spice would have penetrated with strength sufficient for the purpose. But the circumstance of the occasion had not admitted this. She had, she felt, done wonders in achieving so much success as this which she had obtained. If there should be anything disagreeable in the operation, he must submit to it. He had asked for mustard for his throat, and mustard he should have.

As these thoughts passed quickly through her mind, leaning over him in the dark, with her eye fixed on the mixture lest it should slip, she gently raised his flowing beard with her left hand, and with her other inverted rapidly, steadily but very softly fixed the handkerchief on his throat. From the bottom of his chin to the spot at which the collar-bones meeting together form the orifice of the chest, it covered the whole noble expanse. There was barely time for a glance, but never had she been more conscious of the grand proportions of that manly throat. A sweet feeling of pity came upon her, causing her to determine to relieve his sufferings in the shorter space of fifteen minutes. He had been lying on his back, with his lips apart, and as she held back his beard, that and her hand nearly covered the features of his face. But he made no violent effort to free himself from the encounter. He did not even move an arm or a leg. He simply emitted a snore louder than any that had come before. She was aware that it was not his wont to be so loud—that there was generally something more delicate and perhaps more querulous in his nocturnal voice, but then the present circumstances were exceptional. She dropped the beard very softly—and there on the pillow before her lay the face of a stranger. She had put the mustard plaster on the wrong man.
