Knowing that he has not the pleasure of Mrs. Smythe's acquaintance, he turns to the back of the card, and reading there (just the sort of thing he had expected to find) the endorsement, "With Lady Fitzbattleaxe's compliments," he at once grasps the situation, and sends off a note to 150 Queen's Gate, to the effect that he has much pleasure in accepting Mrs. Smythe's kind invitation. He feels quite safe. Lady Fitzbattleaxe and her set, all of whom he knows, will be there; and she wouldn't have sent the card unless she had reason to know that the thing was going to be well done. Unattached bachelors who dance have, in fact, little difficulty in getting their fill of dancing in the season if they lay themselves out for doing so. A young lady can't, as a rule, be asked without at the same time sending a card to her mother or other chaperon, whom the hostess may, from considerations of space or otherwise, not want to have; whereas your dancing-man takes up very little room, brings no one but himself, shifts for himself, and is indeed more or less positively useful toward promoting the avowed object of the gathering. Aware of this, it is a not uncommon practice with dance-going bachelors to interrogate a partner whom they feel a wish to meet again as to the locales of her coming dance-engagements, and thereupon, through the medium of some friend of that potent and wonderful class, the Know-everybodys, to manage somehow to procure for themselves cards of invitation to the houses and parties indicated, whosoever and wherever they may be.

But now, supposing Lady This or Mrs. That to have made up her mind to give a ball, where will she give it? At home, no doubt, in the great majority of cases; but if her rooms happen to be small, or she wishes to avoid the nuisance of having her own house turned upside down (as it must be for a couple of days at the least if a ball is to be held in it), she may prefer—I am assuming expense to be no object—to hire some public rooms, like Willis's, or an empty house for the occasion; of which alternatives it is ten to one that the latter will be adopted. True it is that the ball-room at Willis's (in old days so well known as Almack's), though far too narrow for its length, offers a floor of superlative smoothness, and that its position, in the very heart of the St. James's quarter, leaves nothing to be desired; but the place is so generally associated with festivities of the public and semi-public classes that anybody giving a private dance there may feel sure that the guests will not regard it as quite the same sort of thing as a dance in a private house. The empty-house plan is not open to this objection. Owing its origin, doubtless, to the prodigious amount of house-building that has been going on of late in fashionable London, it has become quite a recognized institution of these last few seasons; and it certainly saves the ball-giver a world of trouble. There stand plenty of newly-built first-class mansions in Belgravia that have not yet found tenants, thoroughly finished off, externally and internally, so far as floors and doors and windows and staircases go, but of course entirely unfurnished. One of these is selected and hired (at a cost that would make some people gasp) for the determined evening. An upholsterer is turned in to put up temporary mirrors, chandeliers and curtains, and lay down temporary carpets; a florist, following, covers bare mantelpieces with captivating layers of cut-roses, ferns and mosses, and empties a whole conservatoryful of plants and flowers into halls and passages; essential Gunter, always equal to any accumulation of occasions, sends in the conventional foods and drinks, and a competent staff of waiters to dispense them; from equally essential and omnipresent Coote and Tinney's comes a detachment of competent musicians; and hey, presto! the empty house bursts into light and life and music, and, exulting in its Cinderella finery, welcomes the guests with all the air of an establishment that has been accustomed to this kind of thing for years.

It is not always an easy matter to time one's arrival at a private ball quite satisfactorily. The old hands have of course certain general rules to go by: for instance, if the invitation-card has borne the words "Small and early" in one corner, that dancing may be expected to begin by eleven o'clock or thereabouts; but in the absence of any such guide it is almost impossible to predict with accuracy the time when arrivals will set in; and so one oftentimes falls into the Scylla of over-lateness in anxiety to steer clear of the Charybdis of over-earliness, or vice versâ. I call to mind a ball at the close of last season to which I went expressly to meet certain friends, and thought to have hit off the happy mean by entering the ball-room just twenty minutes before midnight; but, lo! the musicians had not yet taken possession of their corner, and sofas and chairs were but sparsely occupied by some couple of dozen specimens of that portion of the fair sex who in outward seeming not attractive, for dancing purposes, to the frivolous male, yet for some inscrutable reason always put in the earliest appearances in ball-rooms.

It is all very well to cry out against dances that don't begin till near midnight as absurd and reprehensible; but, after all, their lateness is easily accounted for. In May and June from six to half-past seven in the evening are the pleasantest of hours for driving in the Park or strolling to see others drive there. Nobody willingly goes home till those pleasant hours are over; so no wonder that dinners tend to begin at a quarter- or even half-past eight; that they consequently are not over much before eleven; and that people who have, after that, to look in and gossip for ten minutes at somebody or other's drum, do not find themselves at the ultimate evening engagement, the ball, much before the stroke of twelve. The balls of the London season will not become much earlier, methinks, until some thorough revolution takes place in the likings and habits of the folk who give and go to them.

Suppose, then, the arrival accurately timed, or, at any rate, any fault on the side of over-earliness corrected by a judicious waste of minutes in the cloak- and tea-rooms down stairs. At the top of the inevitable staircase, or just inside her drawing-room, our hostess stands ready with smile and hand-shake for each and every guest announced by the sonorous butler. Many of the younger men (who have received cards by one or other of the side-winds above spoken of) she has very likely never seen or heard of till this moment; but no matter—they and she are equally equal to the occasion. Perhaps the lady who has sent the stranger a card "with her compliments" hears him announced, and stepping forward introduces him to the hostess. If not, the hardly formidable ordeal of a polite bow and a hand-shake passes him on into the ball-room, where, once arrived, he looks about for friends, and proceeds to engage dances, and (let us hope) enjoy them without the slightest sense of strangeness in the strange house, provided only that he has chanced upon a fair sprinkling of his own set there. Who the master of the house may be he probably, if an average careless Gallio, knows little and cares less. Indeed, Paterfamilias is usually content to sink his own personality and be a nonentity for the nonce on the night of his wife's dancing-party.

The suite of drawing-rooms, usually two rooms occupying the whole of the first floor, have been gutted of furniture and stripped of carpets to form the ball-room. The floor is hardly ever of polished wood in modern London houses, but the boards are smooth, and a very tolerable surface for dancing purposes is produceable by the simple process of washing them over with milk. Some people, not caring to go to the trouble of having carpets taken up, content themselves with a holland cloth tightly stretched over the carpeting, which is indeed preferable to that abomination, a beeswaxed floor, but is, at best, but heavy traveling for the dancers, and apt, too, to tear during the evening into dangerous foot-ensnaring holes.

Are you a connoisseur in costumes? The men's dress is, of course, the same, in general appearance, all the Western world over, and the only varieties in a London ball-room are the better or worse styles of tailoring and an occasional white waistcoat. Fortunately, the fair sex, with all the colors of the rainbow and all the inspirations of the fashion-books and dressmakers at command, can and do give a kaleidoscopic plentitude of variety to the scene. Débutantes just "come out" in society are conventionally confined to simple white, but their more experienced sisters may indulge in any combinations of tulle and other gauzy substance, white or colored, with ribbons, flowers, and all the materials and devices known to millinery, at discretion; to all which the rich and stately velvets and silks of the chaperoning matrons form an effective background.

And now for the introductions. There is no getting on at all in a private dance, nor indeed in any London society, without introductions. Society rigidly requires of every man that he submit to the process as a preliminary to addressing even a remark anent the weather to a lady—much more before asking of her such a favor as a dance. But a man who goes much to dances soon grows somewhat wary in this matter. He learns to shun the overtures of the seemingly benevolent people—above all, the master of the house—who proffer willingness to introduce him to partners; for has not experience taught him that such folk are always actuated by the desire (laudable enough, perhaps) of procuring partners for some lady friend whose personal attractions are not, by themselves, calculated to bring them? No, he prefers, the selfish wretch! to seek and choose for himself—first, to look about and determine to which of all the strange faces in the room he would wish to be introduced, and then to set about finding out means of getting introduced to them.

It is a misfortune that the present habits of society, placing the fair sex in the position of waiting to be asked by would-be male partners, as well for dances as for life-partnerships, do not at the same time, in the former as they do in the latter case, countenance their meeting undesired proposals with a direct negative. It is fully admitted in principle, and is said to be experienced in practice, that a lady may reply to the question, "Will you marry me?" with a conclusive "No." But the same answer, given to the stock ball-room interrogatory, "May I have the (honor/pleasure) of a dance?" would be conventionally reprobated as discourteous, and is practically impossible. The natural consequence is, that the fair answerer is driven to all manner of distressing—sometimes almost amusingly distressing—shifts and equivocations, merely to escape the necessity of dancing with men whom she doesn't wish to dance with, but who insist on asking her to do so. Sometimes she salves her conscience by the device of arranging beforehand with a brother or other near relative that she shall be understood to be engaged to him for every and any dance that may be asked for by a person undesired. At other times she will have mislaid her programme, or "think mamma will want to be gone" before the proposed dance is reached. To young ladies thus embarrassed a practice which has recently gained some hold at private balls, of supplying no dance-programmes at all, has afforded a novel and most happy relief. For when one man has asked for (and perhaps fondly noted on his ample cuff) "the third dance from now," another "the second galop," and a third "the fourth round," she is so genuinely bewildered as to how many and what dances she is and is not engaged for that it becomes alike easy to checkmate proposals by the reply "engaged," and at any time in the course of the evening to give an immediate dance to any favored partner, in sheer hopelessness of remembering to whom, if at all, it has already been promised, and on the chance that the unknown will not appear to claim it.
