It is said that Washington never permitted his affairs to destroy his sense of humor. During the time of his occupancy here, an elderly woman was brought before General Putnam. She was believed to be a spy, although she stoutly denied it. It is said that the general, familiarly known as "Put," regarded the case of sufficient importance to be brought to the attention of his commander and insisted that she come with him to headquarters. She was an obstinate woman, and having no fear of capture, resented his treatment, absolutely refusing to enter the gate to the grounds. In vain was she reasoned with until at last, in desperation, the valiant general slung her on his back and brought her up to the house. As Washington witnessed his most courageous officer entering his house in this manner, he could not refrain from laughter, which only incensed the woman all the more. During conferences at headquarters, great care had to be taken lest they be surprised by the British. While one of these conferences was being held, word was sent out that the British were on their way. Without a moment's delay each officer hurried for his necessary adjuncts to meet the emergency. In the midst of the confusion, however, General Greene lost his head and could be heard above the din, calling loudly: "My wig, my wig; where is my wig?" His demand was so emphatic that the attention of the little group was instantly seized. General Lee was the first to regain his composure and with ready wit called out in an equally loud voice: "Behind the looking-glass, General." Greene, passing the mirror, found to his consternation that the wig was on his head. Overjoyed that he was not to go into battle wigless, he joined in the general laugh that followed. The report of the British approach proved false, however, and the officers returned to their consultation. After the estate had been confiscated, it was purchased by one Nathaniel Tracy, an intimate of Washington, whose principal home was in Newburyport, Massachusetts. Tracy was a very wealthy merchant, indeed one of the most brilliant financiers in the country, and his spectacular ventures had given him a prominent name in local history. Tracy was a large landowner, having estates practically all over the country, and while he owned the Vassall house, he rarely lived there, using it simply as a place where he could spend week-ends if he so desired.
