I was not cramped for money.

So I determined to experiment with six machines--three young men and three young women.

I planned that each person should be unconscious of the part he or she was playing, and that each pair should be thrown constantly together--not in society, mind you, for my theory was that conditions must be right.

Through a trusted and highly paid agent I hired my people--the men.

Through another, who was a woman, I hired those of the opposite sex.
