"Sis!" [Illustration: "Hello!"] "I know, Billy," Mary Frances sobbed. "I know!--Father can't come, and everything is ready. Oh, dear! Oh, oh,--de--ar!" "Oh, I say, Sister," said Billy; "I'll pretend I'm Father--won't that do? And--oh, yes! I'll show you how to fold a napkin into 'Cinderella's slipper!'" "Where did you learn how?" Mary Frances began to dry her tears. "Not on land, and not on sea Did this knowledge come to me. When I learned, I had on my hat-- Where was I? Now, riddle me that? * * * * * No, lady fair, not up in the air-- On a boat in the river." [Illustration: "Oh, dear! Oh, oh,--de--ar!"] "Silly Billy!" exclaimed Mary Frances. "Please show me the trick now, will you?" "Yes," said Billy, "and then I'll eat Father's share, as well as mine, of a very 'grand' lunch--if my nose isn't deceiving me." "Well," said Mary Frances, "that will help some; but please fold the napkin." And Billy showed her this: [Illustration: "I'll show you how to fold a napkin."] [Illustration: 1. Fold napkin twice, making it fourfold. Make crease through the center, as shown in =Figure I= 2. Fold each end along _dotted_ line in =Figure I= over to center crease. Then the napkin will be in the form of =Figure II= 3. Fold napkin again along _dotted_ line in =Figure II= over to center. Then it will look like =Figure III= 4. Fold the napkin together along center crease, bring one side exactly over the other. Then the napkin will look like =Figure IV= 5. Fold one side along _dotted_ line in =Figure IV=, turning end _under_, and bringing it up as shown in =Figure V= 6. Fold along _dotted_ line in =Figure V=, bringing point "a" _over_ to meet letter "b". Then the napkin will look like =Figure VI= 7. Tuck the end =A= into opening A-B, folding along dotted line in =Figure VI=, and stand slipper as in =Figure VII=. Fold back and spread open the top, into which slip candy or flowers] Mary Frances was so pleased with the Cinderella's slipper that she folded all the napkins on the lunch table. "Looks like a hotel table," said Billy. "Well, Billy," said Mary Frances, "I know fancy folded napkins aren't so nice for home--but you don't mind." "Indeed, no," said Billy; "I feel proud." * * * * * While they were at lunch there came a knock and a boy from the store handed in a box of candy and a little note addressed to _Miss Mary Frances._ [Illustration: A box of candy and a little note] "Ahem," said Billy, as Mary Frances opened the box, and offered him some candy "since Father couldn't come, he sent a sweet guest in his place." "It isn't very nice to eat up your guest," laughed Mary Frances. "Mary Frances," asked Billy, "what's better than a cream chocolate?" "Two cream chocolates, I guess," said Mary Frances, passing the box--"but, Billy, listen: [Illustration: "What's better than a cream chocolate?"] "Dear Miss Mary Frances:
