"Oh, we are not building big ones yet," answered David. "These are little fellows. Models, you know. The big ones may come later. Six of the junior and senior fellows have been working on them all summer. We started it in the manual training course. After we had learned to hammer things out of silver, and do wood carving and a few other little useful accomplishments, I suggested a flying machine to Professor Blitz and he fell to it like a ripe peach. It was too late to do anything last spring except talk, however. But we are almost ready now, after our labors this summer."
"Ready for what?" demanded Grace. "If you are not going to fly yourselves."
"For our exhibition. Why don't you come and see it at the gym. next Friday night?"
"We can't. We aren't invited," answered Nora, tossing back her saucy little curls.
"I'll invite you," said David. "This will admit four young ladies to the High School gym.," he continued, taking out a card and writing on it, "At 7.30 Thursday evening."
"Then everybody isn't invited?" demanded Jessica.
"No, not everybody," replied David. "Just a chosen few. And you must be sure to come, too, Miss Pierson," he added, turning to Anne, who, all this time, had been silently listening to the conversation.
"I should love to," she answered, giving him a grateful glance.
"I'll leave you here," said David, turning in at a graveled driveway that led to the Nesbit house, a very large and ornate building standing far back from the street in the midst of a well-kept lawn.
"I wish Miriam would take a few lessons in manners from her brother," murmured Grace, when they were out of hearing distance.
