   spretta to sprit, spring.]
   A sudden and energetic effort, as in an emergency; an
   increased exertion for a brief space.

         The long, steady sweep of the so-called ``paddle''
         tried him almost as much as the breathless strain of
         the spurt.                               --T. Hughes.

   liquor from a cask; to rush from a confined place in a small
   stream or jet; to spirt.

         Thus the small jet, which hasty hands unlock, Spurts in
         the gardener's eyes who turns the cock.  --Pope.
