Quicksand \Quick"sand`\, n.
   Sand easily moved or readily yielding to pressure;
   especially, a deep mass of loose or moving sand mixed with
   water, sometimes found at the mouth of a river or along some
   coasts, and very dangerous, from the difficulty of
   extricating a person who begins sinking into it.

         Life hath quicksands, -- Life hath snares!
                                                  --Longfellow.
