Governor Winslow, of Plymouth, who advised him to leave Seekonk, entered on his official duties in March, 1635–6. This was the only year that he held the office of Governor, between 1633 and 1644.[135] Mr. Williams must, therefore, have been at Seekonk, subsequently to the date of Governor Winslow’s accession to office. In Mr. Williams’ letter to Major Mason, he says, that he “began to build and plant at Seekonk.” He did not begin to plant, we may presume, till the middle of April, if so early.[136] In the same letter, he speaks of his removal as occasioning his “loss of a harvest that year,” from which remark we may reasonably infer, that the corn had attained a considerable growth before he left Seekonk, and consequently that he did not cross the river till the middle, perhaps, of June. On the 26th of July, a letter was received from Mr. Williams, by Governor Vane, informing him of the murder of Mr. Oldham, by the Indians of Block-Island.[137] This letter was written at Providence, and it proves, that Mr. Williams had removed thither previously to the 26th of July. We may safely conclude, that he left Seekonk, not far from the middle of June, 1636. The exact day will never, it is probable, be ascertained.[138] There is one circumstance, which, perhaps, misled Mr. Callender and Governor Hopkins respecting the year of Mr. Williams’ arrival. In a deed, signed by himself and wife, and dated December 20, 1661, he used these words: “Having, in the year one thousand six hundred thirty-four, and in the year one thousand six hundred thirty-five, had several treaties with Canonicus and Miantinomo, the two chief sachems of the Narragansets, and in the end purchased of them the lands and meadows upon the two fresh rivers, called Moshassuck and Wanasquatucket, the two sachems having, by a deed under their hands, two years after the sale thereof, established and confirmed the bounds of these lands.” The statement, that he had held several treaties with the Narraganset sachems, in 1634 and 1635, presents some difficulty. But we have already seen, that while at Plymouth and at Salem, he held some intercourse with these chiefs. In a manuscript letter, already quoted, he says: “I spared no cost towards them, and in gifts to Ousamequin and all his, and to Canonicus and all his, tokens and presents, many years before I came in person to the Narraganset; and therefore when I came, I was welcome to Ousamequin and to the old prince Canonicus, who was most shy of all English to his last breath.”
