"There is one interesting thing about it though. They're also including a live animal with the instruments. A cat I believe. They want to see what effect the cosmic rays will have on a living creature."

The girl turned a shocked face toward him as they walked up the steps to the front door of the house. Trent could see a panel in the center of the door that opened from the inside, and over it, the sign, Doctor is in, please ring.

"But I think that's positively cruel!" Joan Drake said earnestly. "Subjecting an innocent animal to what may be certain death!"

Fred laughed at her concern. "Hold on, now. You should be the last one to take such an attitude. Doesn't medical science experiment on animals to find out about human ailments?"

"That's different," the girl insisted, opening the door and leading the way into a long hall. "Doctors know what they are doing—but this is a sheer waste of life ..."


Trent let the dog pull him down the hall toward a door at the end which he knew opened on the backyard where the Great Dane was kept.

"Seems to me it's much the same thing," he answered her. "Scientists want to explore the mysteries of space, and the only way to do it is with an animal. Or would you like to make the trip—maybe I can arrange it? Would make a big story, just the one I've been waiting for."

"I believe you would at that!" she mocked, opening the rear door. "Here, give me the leash."

Trent handed over the leash to her and watched as she released the huge dog. Brutus flicked out a long tongue once again and caught the girl's cheek in a wet caress before she straightened.
