Brett said, "Father was insistent that we make every advance test possible. We have already used two of them. We are going to test the others today." "Now," exclaimed Frannie. "Do it now--Frank will want to see it." Dr. Gryce lifted one of the vehicles. In his hand it seemed light as alemite. He placed it on a taboret and we sat grouped around it. "I shall send it into Time," he said quietly, "with its size unchanged, with no motion in Space, so that always in relation to us it will remain right here--I am going to send it back into other ages of Time." He turned to me earnestly. "We wanted you here, Frank, because you are so good a friend to me and my children. But for a selfish reason as well. When Brett goes out into Space and Time tonight, I want your keen eye to follow him. Your ability to record so accurately on the clocks what you see at any given instant----" He was referring to my experience at the Table Mountain observatory--my first work when my training period was over. I had, indeed, a curiously keen vision for astronomical observation, and a quickness of finger upon the clock to record what I saw. In transit work I was extremely accurate; even now they were asking the Postal Division for my services at Table Mountain in the forthcoming transit of Venus. Dr. Gryce was saying, "Your accuracy is phenomenal, Frank--your figures as you observe what little we see of this flight will help me--set my mind at rest that Brett is making no errors." He ended with a smile, "So you realize we have a selfish motive in wanting you."
