For the Proclamation of 1763, what would you think a good compromise would be betweent the colonies and England at the time?

The Proclamation 0f 1763 reflected the reality that the British now in control of Canada had taken the place of the French in the fur trade.
The native American tribes were now trading furs with the British in Canada. To maintain the fur trade the British needed to keep the tribes happy. Keeping the tribes happy meant preventing incroachment of Native hunting grounds by the American colonists

The American colonies were founded on the idea of free land. The American colonists came to North America to own their own land and become rich. As more land east of the mountains was taken the colonists were determined to claim land west of the mountains.

During the French and Indian wars the colonist had started to move west. Daniel Boone and his fort was founded West of the mountains beyond the line drawn by the Proclamation of 1763. The British were trying to force these colonist back across the mountains and stop any more colonists following them.

The Conflict between the desire of the colonists for more land and the desire of the British to protect the lucrative fur trade had no room for compromise.
