"I don't know yet; he won't tell me."
"Yes, I'll tell you to-morrow," said her brother. "But what's this about Father going away, Mother? Are we going too?"
"Supper am ready, chilluns!" exclaimed the voice of Dinah, the cook, and that ended the talk about secrets for the time being.
"But when are you going to tell me yours?" Nan managed to whisper to her brother when the dessert was being served.
"Come down to the lumberyard to-morrow afternoon," he whispered. "It's almost done."
Without telling Flossie or Freddie anything about it. Nan slipped off by herself the next afternoon, and from the watchman in her father's lumberyard learned that Bert and another boy were in one of the sheds. As Nan came closer she could hear the noise of hammering and sawing.
"Oh, Bert, what are you making?" cried Nan, as she saw her brother and Tommy Todd busy with sticks, boards, hammer and nails.
"This is the Bird!" cried Bert, waving a hammer at something that, so far, did not look like much of anything.
