wish I could remember how that time machine was built and operated," said Dr. Bird reflectively, as he sat in his private laboratory in the Bureau of Standards some time later, "but Jumor did his work well. I can't even remember what the thing looked like."

"Well, Doctor, our trip below wasn't a loss. We removed a very real menace to the established order of things and we have got rid of Saranoff temporarily. It will take him some time to return here from Russia."

"Three weeks or less," said Dr. Bird pessimistically. "However, we have gained one other thing. Did you notice this?"

He pulled what looked like a watch from his pocket. Carnes regarded it with a puzzled expression.

"No, Doctor, what is it?"

"It is a very small camera which takes pictures one-half inch by seven-eighths. I had several opportunities to use it. I wasn't sure that it would work on such short waves, but it did. When Saranoff tries to return to this country, he will find that every immigration inspector and every member of the border patrol has an excellent likeness of him. That may hinder his entrance into the country for a little while."


A CLASSIFICATION OF THE UNIVERSE

A classification of everything in the universe, from the smallest thing yet measured, the electron, less than a millionth of a millionth of an inch in extent, to the biggest, a star system of a thousand million trillion miles, was described recently by Prof. Harlow Shapley of Harvard in a lecture at the commerce center of the College of the City of New York.
