There came a time when his deep unconsciousness was invaded by a very strange and wonderful sensation.

He no longer felt himself lying motionless in bed, as he had been doing for so long.

He seemed rather to be floating, as one might float along the current of a strong, swift stream.

He felt no bed under him, though what it was that held him up he couldn't guess, and it never occurred to him to wonder.

All he knew was that his pains had vanished, that his body was scarcely palpable, and that the smooth, gliding motion--if motion it could be called--was the most exquisite sensation he had ever felt.
