WAIFS. Stolen goods waived or scattered by a thief in his flight in order to 
effect his escape. 
     2. Such goods by the English common law belong to the king. 1 Bl. Com. 
296; 5 Co. 109; Cro. Eliz. 694. This prerogative has never been adopted here 
against the true owner, and never put in practice against the finder, though 
against him there would be better reason for adopting it. 2 Kent, Com. 292.
