Chiltern Hundreds
From BiblePortal Wikipedia
Webster's Dictionary [1]
A tract of crown land in Buckinghamshire and Oxfordshire, England, to which is attached the nominal office of steward. As members of Parliament cannot resign, when they wish to go out they accept this stewardship, which legally vacates their seats.
The Nuttall Encyclopedia [2]
A wardship of beech forests on the Chiltern Hills against robbers, that at one time infested them; now a sinecure office, the acceptance of which enables a member of Parliament to resign his seat if he wishes to retire, the office being regarded as a Government one.
