Seeker of To-Morrow

I had set up my laboratory in the wilds of the Peak District in Derbyshire, in England, where work could be carried on with the minimum of interference. From this laboratory I had dispatched into the unknown, presumably the future, a multitude of objects, including several live creatures such as rats, mice, pigeons and domestic fowl. In no case could I bring back anything I had made to vanish. Once gone, the subject was gone forever. There was no way of discovering exactly where it had gone. There was nothing but to take a risk and go myself.
