Answer:
Thomas Putnam accuses his neighbors of witchcraft so that he can cheaply buy their land.
Explanation:
The Crucible (1953) is Arthur Miller's tragedy play in which many innocent people of Salem are falsely accused of witchcraft, arrested, tried wrongly and nineteen of them are hanged to death.
There are many references throughout the play that Thomas Putnam is a greedy and rich landowner who want to grab other's property/land by hook or by crook. He accuses not only John Proctor of witchcraft but many others of his neighbors as well.
Some references from the playing mentioning this fact are;
Putnam: <em>Why, we are surely gone wild this year. What anarchy is this? That tract is in my bounds, it’s in my bounds, Mr. Proctor.
</em>
Proctor: <em>In your bounds! indicating Rebecca: I bought that tract from Goody Nurse’s husband five months ago.

Proctor:<em> </em><em>Your grandfather had a habit of willing land that never belonged to him, if I may say it plain.</em>

Giles Voice: "<em>Thomas Putnam is reaching out for land!"</em>
Giles:<em>"And there is none but Putnam with the; coin to buy so great a piece. This man is killing his neighbors for their land!"</em>
