Gould's school principal was credited with getting him a job as a bookkeeper for a blacksmith. A year later, the blacksmith offered him half interest in the blacksmith shop, which he sold to his father during the early part of 1854. Gould devoted himself to private study, emphasizing surveying and mathematics. In 1854, he surveyed and created maps of the Ulster County, New York, area. In 1856, he published "History of Delaware County, and Border Wars of New York," which he had spent several years writing.
