“Whatever made you think about birds?” asked Katherine wonderingly. “You jump from one subject to another like a flea. I don’t see how you can keep your mind on your work long enough to invent anything. By the way, how is that thingummy of yours going? You’re as mum as an oyster about it.”

“Pretty well,” replied Justice. “I’m hampered though, by not having the right kind of help, and not being able to get some of the things I need.”

Katherine looked at him scrutinizingly. He looked tired and rather worn. The nonsensical boy had vanished and a man stood in his place, a man with a heavy responsibility on his shoulders. Justice had that way of changing all in an instant from a boy to a man. At times he would go frolicking about the house till you would have sworn he was not a day older than Slim and the Captain; an instant later he was all gravity, and looked every day of his twenty-six years.

Katherine always stood in awe of him whenever that change took place. He seemed so old and wise and experienced then that she felt hopelessly ignorant and childish beside him. She liked him best when he seemed like the other boys.

“What do you think of my Winnebagos?” she asked him, leading him away from the subject of his work. He always got old looking when he talked about it.

“Greatest bunch of girls I ever saw,” he replied heartily. “Never came across such an accomplished lot in all my life. Each one’s more fun than the next. Hinpoha’s a beauty, and Gladys is a dainty fairy, and Sahwah looks like a brown thrush, and Migwan’s a regular Madonna. And, say—would you mind telling me how you do it, anyway?”

“Do what?”

“Stick together like that. I thought girls always squabbled among themselves. I never thought they could do things together the way you girls do.”

“Camp Fire Girls can do things together!” Katherine informed him with emphasis. “You boys think you’re the only ones that know anything about teamwork. Teamwork is our first motto.”

“I guess it must be,” admitted Justice. “You certainly are a team.”
