"To be sure, go on," said Bea with interest and creasing down a hem with much satisfaction in the thought that her hands looked very pretty and white, almost as pretty as Ernestine's.

"Well you see," began Kitty, as Kat retired under her hat in a spasm of unusual modesty, "when we came in from recess this afternoon, Kat wanted to sit in my side of the seat, and told me to act as if I was she, so I thought it was to be a lark of some kind and did, but dear me——"

"Well go on," said Ernestine with languid curiosity, as Kittie paused to laugh at some recollection.

"Just as soon as we got in Miss Howard told us to put books away; then she gave us the breeziest lecture and was as solemn as an owl. I couldn't imagine what was up. Susie Darrow was crying with her handkerchief to her nose, Kat looked as if she was sitting on pins and needles, and I really thought that Sadie Brooks and May Moor would eat us up, the way they actually glared at us. Well, the first thing I knew, Miss Howard was saying something about a needle in Susie Barrow's pen, that she had stuck her nose with, and she wanted whoever had put it there to come to her desk. That's the way she always does, you know; never calls a name unless she finds she has to, and bless you! who should I see walking off but Kat, and what does Miss Howard do but take her ruler and give her fifteen slaps on the hand. Kat, I'm meaner'n dirt, and you're a jewel; you did beat, I'll own up."

"No such thing, you beat yourself," came in a sepulchral growl from under the hat.

"Well I'm sure I don't see the point," said Ernestine with impatience. "It was very rude and unlady-like to put a needle in Susie's pen and you deserved your fifteen slaps."

"Just wait 'till I finish, will you," cried Kittie, as the hat maintained perfect silence, "Kat didn't do it, but she heard that I did, and that I was going to be whipped, so she took my seat and jumped up the minute Miss Howard spoke, and the only way I found out was when Miss Howard said, 'Now Kittie you must beg Susie's pardon before the school.' Then I knew something was up, and just popped right out of my seat and said that that was Kat, not me, and didn't it make a hub-bub, and didn't Miss Howard look funny!"

"It was lively," broke in Kat, and coming out from under the hat as if inspired with the recollection, "Miss Howard looked as blank as you please, and like to have never gotten at the straight of it; but after awhile lame Jack told how he had seen Sadie and May fix it themselves, and plan to tell it was Kittie, and oh didn't they look cheap, and didn't they creep off to-night and take every book along?"

"But wasn't Kat just too dear and good to take a whipping to save me," cried Kittie, throwing both arms around her twin in a hug full of devotion. "I'll never forget it, Kat Dering, never!"

"Well you'd better," said Kat, on whom praise and glory rested uneasily, though she looked pleased and returned the hug with interest. "You'd have done it for me, I know, and I would again for you any day. Let's go out on the roof; it's much cooler than here."
