a traditional Easter custom in northern England, Scotland, Northern Ireland and the Isle of Man . Each person taking part rolls a hard-boiled egg down a slope, and if it is not damaged at the bottom they will be lucky in various ways. Egg-rolling was introduced into the US in 1877 by Dolly Madison, the wife of President James Madison . It was originally done at Easter on Capitol Hill in Washington, DC , and later in the grounds of the White House (1), where it still happens every year, except in time of war. It also takes place in many local communities.
