"The Merry Hearts," most of whom were in the ten o'clock division, exchanged swift glances, and then tried to conceal their amusement or embarrassment in various characteristic fashions. Madeline and Roberta, each wearing an expression of lamb-like innocence, stared inquiringly at Dr. Eaton. Bob stuffed her handkerchief into her mouth to keep from laughing out loud. Helen studied her note-book with an air of intense absorption. Babe, Babbie and Betty played with their fountain pens and tried vainly not to look ill at ease. The rest of the class, however, made no particular effort not to look interested, and Dr. Eaton, in spite of his impersonal attitude toward his young charges, must have detected something unusual in the air.
