Of late years it is becoming common not to give entertainments at one's residence, but to hire public rooms set apart for that purpose. There is a large house in the upper part of Fifth avenue, which is fitted up exclusively for the use of persons giving balls, suppers, or receptions. It is so large that several entertainments can be held at the same time on its different floors, without either annoying or inconveniencing the others. The proprietor of the establishment provides everything down to the minutest detail, the wishes and tastes of the giver of the entertainment being scrupulously respected in everything. The host and hostess, in consequence, have no trouble, but have simply to be on hand at the proper time to receive their guests. This is a very expensive mode of entertaining, and costs from 5000 to 15,000 dollars, for the caterer expects a liberal profit on everything he provides; but to those who can afford it, it is a very sensible plan. It saves an immense amount of trouble at home, and preserves one's carpets and furniture from the damage invariably done to them on such occasions, and averts all possibility of robbery by the strange servants one is forced to employ. Still, many who possess large and elegant mansions of their own prefer to entertain at their own homes. On such occasions, the lady giving the entertainment issues her invitations, and usually summons the famous Brown, the Sexton of Grace Church, to assist her in deciding who shall be asked beyond her immediate circle of friends. Mr. Brown is a very tyrant in such matters, and makes out the list to suit himself rather than to please the hostess. He has full authority from her to invite any distinguished strangers who may be in the city. Upon the evening appointed a carpet is spread from the curbstone to the front door, and over this is placed a temporary awning. A policeman is engaged to keep off the crowd and regulate the movements of the carriages. About nine o'clock magnificent equipages, with drivers and footmen in livery, commence to arrive, and from these gorgeous vehicles richly dressed ladies and gentlemen alight, and pass up the carpeted steps to the entrance door. On such occasions gentlemen are excluded from the carriage if possible, as all the space within the vehicle is needed for the lady's skirts. The lady is accompanied by a maid whose business it is to adjust her _toilette_ in the dressing room, and see that everything is in its proper place. At the door stands some one, generally the inevitable Brown, to receive the cards of invitation. Once admitted, the ladies and gentlemen pass into the dressing rooms set apart for them. Here they put the last touches to their dress and hair, and, the ladies having joined their escorts, enter the drawing room and pay their respects to the host and hostess. When from one to two thousand guests are to be received, the reader may imagine that the labors of the host and hostess are not slight.
