MANY INVENTIONS 19

went to live in the little village of Powick, about three
miles out of Worcester. He enjoyed his work, and
had the new experience of establishing relations with
a number of children, with whom he soon became a
favourite. Long afterwards, in his declining years he
found much gratification in making friends with
children, and referred to it quaintly as " a vicarious
phase of the philoprogenitive instinct." It was at

style. It was at Powick, too, in a physical and

invented his " Velocimeter," a little instrument for
showing by inspection the velocity of an engine, and
two or three other devices. He had inherited his
father's constructive imagination, and his father's

" probably the most remarkable inventor who ever
lived," was a self-trained man, and that Sir Benjamin
