Thomas Putnam of either conspiring with others, or directly charging people with witchcraft, in order to gain more land. Thomas is one of many who are capitalizing on the hysteria for their own gain. Abigail does not want land, but she wants John Proctor.

Giles is beside himself because his wife, Martha has been accused of witchcraft and is being held in jail. Giles feels somewhat responsible because he questioned her reading books he did not understand. However-Giles has a long history of legal issues with the people in the community. He has sued people many times. He is quite litigious, and this works against him.

The court is angry with his accusations, and literally throws him out of the room, where he will be dealt with later. When the court does turn their attention back to Gile's allegations against Putnam, he will be the one who ends up in jail.

Giles Corey comes to court in ACT III to file a deposition that Thomas Putnam is essentially encouraging his daughter to accuse people of witchcraft so that he can claim their land. When someone is tried and convicted of witchcraft, their land goes up for auction and can be purchased at an extremely reduced rate; therefore, if Putnam wanted someone's land, Giles Corey's claim is that he asks his daughter to accuse that person of witchcraft so that he can eventually buy their land:

Giles: My proof is there!

Pointing to the paper. If Jacobs hangs for a witch he forfeit up his property - that’s law! And there is none but Putnam with the; cointo buy so great a piece. This man is killing his neighbors for their land!

Danforth: But proof, sir, proof.

Giles,pointing at his deposition: The proof is there! I have it from an honest man who heard Putnam say it! The day his daughter cried out on Jacobs, he said she’d given him a fair gift of land.

Another important development here is that Giles refuses to reveal the name of the man who told him this information, because he hears that people who have signed the first deposition are being taken into custody. Giles refuses to damn another person to hang, and he is eventually pressed to death because he won't cooperate with questioning. Because he says nothing when asked if he is guilty of witchcraft, his sons are able to inherit his land and his property is not auctioned.

The first instance concerning Thomas Putnam's comments regarding a land dispute occurs in act one. While Thomas Putnam, John Proctor, and Giles Corey are visiting Reverend Parris's home, the men begin to argue about Reverend Parris's decision to call Reverend Hale to investigate witchcraft. Before Proctor leaves Parris's home, he asks Giles Corey to follow along and help him drag some lumber home. Thomas Putnam then interrupts and asks Proctor where the lumber is located that he plans on hauling home. When Proctor says that it is from his land by the riverside, Thomas Putnam responds by saying,

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 (Miller, 32).

When Proctor responds by saying that he purchased the land from Goody Nurse's husband five months ago, Putnam insists that all the land in between the river belonged to his grandfather, who happened to write it in his will. Proctor and Corey immediately dismiss Thomas Putnam's threats to "clap a writ" on them before they leave the Reverend's home. 

This part of the play occurs in Act III, when Giles Corey, Francis Nurse, John Proctor and a reluctant Mary Warren come to the court to try and put a stop to the madness that is going on. Giles Corey delivers a paper to Danforth stating that Putnam prompted his daughter to "cry witchery" on George Jacobs so that he could seize his land. Actually, throughout this entire scene, the only thing that Putnam says is "It is a lie", which Giles meets with customary vim and vigour by responding: "A fart on Thomas Putnam, that is what I say to that!"

Giles Corey goes on to unfold his case. He states:

If Jacobs hangs for a witch he forfeit up his property - that's law! And there is none but Putnam with the coin to buy so great a piece. This man is killing his neighbours for his land!

In addition, Giles Corey adds:

I have it from an honest man who heard Putnam say it! The day his daughter cried out on Jacobs, he said she'd given him a fair gift of land.

Of course, it is his reluctance to give the court the name of his informer that gets him into trouble and leads eventually to his death. Thus, in response to your question, unfortunately Putnam only says four words, but what is tragic is that he doesn't need to say more - the rules of the court are stacked against Corey and Proctor and others like them, providing Putnam with the loopholes he needs to commit his evil crime of getting his daughter to cry witchery on others for personal gain.

At this point, Giles Corey believes that Thomas Putnam is having his daughter cry witch against people on purpose.
Once a person is hanged for witchcraft, his land is taken away and is auctioned off to the highest bidder. It cannot be left to family of the hanged person. Thomas Putnam was one of the few men in Salem who had the means to buy the property. Giles feels Putnam is so greedy for land that he is willing to have his neighbors hanged for witchcraft to get it.

Later, Giles Corey found a way to get around this law. He refused to answer the indictment (accusation) of witchcraft against him. He would not answer yes or no to the accusation. Since he wouldn't answer, the court couldn't take his land away, and Giles was able to pass it down to his son. Instead of being hanged, Giles was "pressed to death" by having heavy rocks placed on his chest until he died. They were trying to get him to answer the indictment.

In act 3, Giles Corey presents a deposition against Thomas Putnam to Deputy Governor Danforth in an attempt to expose the court's proceedings as a fraud and to free a wrongly accused citizen. Giles Corey's deposition states that an honest, respected citizen overheard Thomas Putnam instructing his daughter to accuse George Jacobs of witchcraft so that Thomas could buy George Jacobs's forfeited property. Thomas Putnam knows that if a citizen confesses to being involved in witchcraft, the convicted citizen must forfeit their property. Giles Corey tells Deputy Governor Danforth that Thomas Putnam is the only citizen with enough money to buy Jacobs's property and is using the witch trials as a land grab. Unfortunately, Deputy Governor Danforth demands that Giles Corey name the person who overheard Thomas Putnam speaking to his daughter, and he refuses to tell him. Danforth then charges Giles Corey with contempt of court, and he is eventually pressed to death.
