The Nipmuc regrouped around their former Praying towns and were able to maintain a certain amount of autonomy using the remaining lands to farm or sell timber. The population of the tribe was reduced as several outbreaks of smallpox returned in 1702, 1721, 1730, 1752, 1764, 1776 and 1792. Land sales continued unabated, much of it used to pay for legal fees, personal expenses, and improvements to the reserve lands. By 1727, Hassanamisset was reduced to 500 acres from the original 7,500 acres with that land incorporated into the town of Grafton, Massachusetts, and in 1797, Chaubunagungamaug Reserve was reduced to 26 of their 200 acres. The switch to the cattle industry also disrupted the native economy, as the colonists' cattle ate the unfenced lands of the Nipmuc and the courts did not always side with the Native Americans, but the Native Americans rapidly adopted the husbandry of swine since the changes in economy and loss of remaining pristine lands reduced ability to hunt and fish. Since the Native Americans had few assets besides land, much of the land was sold to pay for medical, legal and personal expenses, increasing the number of landless Native Americans. With smaller numbers and landholdings, Indian autonomy was worn away by the time of the Revolutionary War, the remaining reserve lands were overseen by colony- and later state-appointed guardians that were to act on the Native Americans' behalf. However, the Hassanamisco guardian Stephen Maynard, appointed in 1776, embezzled the funds and was never prosecuted.
