The waiter appeared, carrying the tray waiter-fashion on his hand.  It contained three very small cups of weak tea, and about five tiny wafers of the thinnest bread and butter.  There was a little sky-blue milk in a jug, and a few lumps of sugar in a little silver basin.  Mrs. Aylmer glanced at the meal as if she were about to give her sister-in-law and her niece a royal feast.  "This is most exciting," she said; "we will enjoy our tea when you, Florence, have explained yourself.  So you know Sir John Wallis.  When you see him again pray remember me to him."
