Then lifting up his eyes from off the book
  He on his guest a look of science threw:—
 ‘He that would fish must firstly bait the hook;—
  No fishes nibble here until you do.’
 Our hero took the hint, and forthwith drew
  From out his fob the heart case that he tanned,
 When, years agone, a fatted ox he slew;
  Its contents o'er with wishful eyes he scann'd,
And dropped a part thereof into the wizzard's hand.
