An old blacksmith relized he was soon going to quit working so hard. So he picked out Santa to become his apprentice. The old fellow was crabby and exacting.
'Don`t ask me a lot of questions, ' he told Santa. 'Just do whatever I tell you to do.'
One day the old blacksmith took an iron out of the forge and laid it on the anvil.
'Get the hammer over there, ' he said. 'When I nod my head, hit it real good and hard.'
Now the town is looking for a new blacksmith.

Edwin Drood
