Tweed's earliest boyhood recollection is associated with the discovery, not far from his home, of a spring, possessed, it was claimed, of great curative powers. He was then four years old. Young Tweed was feeling out of sorts, when the High Constable of the city, Jacob Hays, visited the shop of his father to order some chairs. The child was sitting quietly in a corner. On learning the child was not well, the High Constable recommended that a bottle of water from a newly found spring be procured. Hays assured the parental chairmaker that the waters were of greater efficacy than any from the most famous European spas. They had cured him of a complaint of many years’ standing. The High Constable's suggestion was acted upon forthwith. The bottle of water cost a few cents, for the owner of the spring was making the most of it.
