Instead of introducing our readers to the gay assemblage of this lady's guests, we will take them to the dressing-room of the fairest among them, the beautiful, the gay, the brilliant Caroline Danby. As the door of this inner temple of beauty opens at the touch of our magic wand, its inmate is seen standing before a mirror, and her eye beams, and her lip is smiling with anticipated triumph. Does there seem vanity in the gaze she fastens there? Look on that form of graceful symmetry, on those large black eyes with their jetty fringes, on the rich coloring of her rounded cheeks, and the dewy freshness of her red lip, and you will forget to censure. But see, the mirror reflects another form--a form so slender that it seems scarcely to have attained the full proportions of womanhood, and a face whose soft gray eyes and fair complexion, and hair of the palest gold, present a singular contrast to the dark yet glowing beauty beside her. This is Mary Grayson, the orphan cousin of Caroline Danby, who has grown up in her father's house. She has glided in with her usual gentle movement, and light, noiseless step, and Caroline first perceives her in the glass. "Ah, Mary!" she exclaims, "I sent for you to put this diamond spray in my hair; you arrange it with so much more taste than any one else." Mary smilingly receives the expensive ornament, and fastens it amidst the dark, glossy tresses. At this moment the doorbell gives forth a hasty peal, and going to the head of the stairs, Mary remains listening till the door is opened, and then comes back to say, "Mrs. Oswald, Caroline, and Philip." "Pray, go down and entertain them till I come, Mary"--and seemingly nothing loth, Mary complies with the request. In the drawing-room to which Mary Grayson directed her steps stood a stately looking lady, who advanced to meet her as she entered, and kissing her affectionately, asked, "Are you not going with us this evening?"
