How does Putnam coerce Parris to declare witchcraft in Act I?

In many ways, Putnam proves to be as malevolent as Abigail
or Parris.  Unlike both of them, Putnam is fairly clear and direct about what he wants
to do and what he covets.  He recognizes that both his wife will be pleased and he will
benefit with more accusations.  His wife will be happy because her own paranoia about
her dead children will be satiated.  At the same time, Putnam would be able to
consolidate more land with the more people accused, something that Corey brings out in
Act III.  Putnam makes it very clear that by starting to make the case of witches to the
crowd that has gathered downstairs will accomplish two things.  The first thing
accomplished would be that individual attention would be focused away from what the
girls were doing in the woods that night, and also from Ann's insistence that Betty
speak with Tituba about her dead babies.  The other thing accomplished would be that
Parris would become extremely powerful being a minister in a time where fear of witches
and concerns of witchcraft would have held over the town.  It is for this reason that
Putnam convinces and coerces Parris to speak of witchcraft
immediately.
