"I smelled a rat when I saw that carryall by Bill's door, but I never dreamed that Miss Miller had planned it. I thought perhaps some of our folks were coming down to surprise us, and I was delighted to think it fell on your birthday," said Zan.
Then the Guide told how she first got the idea to surprise them in return for their secrets.
"Well, the doctor seems thoroughly pleased with our experiment, doesn't he?" said Hilda, remembering the wondering looks of all of the parents.
"Indeed he is! He told me, just before leaving, that the remarkable improvement in Zan and Nita far surpassed the others," said Miss Miller.
"Me! Why, I am always all right! What did he mean?" questioned Zan, astonished.
"He missed a most familiar habit, and said that the improvement was to be continued," laughed the Guide.
"Ha, ha! Zan, he meant your slang!" cried Elena.
"Oh, but I haven't quit that yet! I shall some day!" added Zan.
"You have dropped so much of it that it is remarked by those who have not heard you in a month, but to yourself it may not seem such an improvement," explained Miss Miller.
