Rick knew that was one of the many world-wide private scientific organizations operating under the International Council of Scientific Unions. He also knew of the growing importance of radio astronomy, but he hadn't known the Egyptians were in on it.

"Apparently some unusual trouble developed during the tuning of the instrument," Winston went on. "Earlier this afternoon I had a phone call from Cairo, and a request to help our Egyptian colleagues iron out the bugs. I accepted."

Rick sat upright in his chair. Winston going to Cairo? How did this concern Scotty and him?

"My proposal is this," Winston concluded. "The Egyptians are short of technicians and we may need help. I'll leave the day after Christmas, returning within ten days. If you two can pay half your expenses, and help me half the time, I'll take you with me."

Both boys jumped to their feet. Rick looked anxiously at his father.

Hartson Brant smiled. "According to Parnell's schedule, you'll be back just in time for school at the end of the holidays. If you want to go, of course."

Rick let out a wild yell of exuberance that brought his sister Barby running to the library. She looked at the group with wide eyes. "Rick! Was that you?"

He grinned at her. "It wasn't a wounded buffalo, Sis. Guess what? We're going to Egypt!"

Barby's pert face lengthened. "I don't suppose I can go, too?"

Parnell Winston walked over and ruffled her blond hair. "Not this time, Barby. But I'll make you a promise. The next field expedition under my supervision will include my wife, you, and Jan Miller."
