The boy refused any offer of money for the service, saying that it was his good turn as a Boy Scout. Boyce was interested in this and visited Baden-Powell before he left London to discover more of this. When he got back to the USA he set up the movement the Boy Scouts of America. By 1918, its number had risen to 300,000, and had reached the million mark before the end of the twenties.
