Significantly, he left room to inscribe the first crossing of the Atlantic Ocean by an American steamship. There were originally 7 natural pools and springs that existed within the massive property. Peale took advantage of these natural pools and utilized them to improve his massive garden. He hollowed out the source of the spring into an artificial cave, which he then lined with masonry. This spring fed a greenhouse with a glass ceiling. Unfortunately only two of the original seven pools remain today. The other five have either disappeared due to natural reasons or have been diverted to another location. There used to exist a spring within the "Summer House" until that was diverted along with two pools that existed by the kitchen that fed into a well and one that existed near the lower half of the stable. These have since disappeared and it is unknown exactly how the last two disappeared. To the southeast was a pool with a ten-foot fountain that was fed by pipes from the spring. Next to the pool was a garden shed onto which Peale painted a "gate" to disguise it. On the "gate" were symbols and figures representing Congress, America, Truth, Wisdom, Temperance, and Mars, the Roman God of war. The ruins of Peale's cave and greenhouse still stand. The cave is now underneath the stump of a coffee tree, but the deteriorating masonry is still visible. The greenhouse's walls are to the west, and are mostly overgrown with brush and ivy while the location of Peale's pond has been paved over by a driveway. While the condition of the gardens and greenhouses may have deteriorated during the unforgiving embrace of time, they once used to be magnificent, with numerous flora of all kinds scattered all throughout the greenhouses and on the grounds. The flora included a fig tree to the south side of the small gardener's cottage along with a box tree only a couple of yards away. This tree was replaced several times during the history of Belfield. There were numerous transplanted trees that are scattered throughout the land but throughout all the years, only one tree can be described as the strongest and longest lasting. This is the old hickory tree that was and still is standing near the greenhouses. After purchasing the property from Peale, William Logan Fisher and wife Sarah Lindley Fisher lived on the estate. Sarah Lindley Fisher attracted a lot of guests when she arrived to the estate. Together the two had three children. The first was Sarah Lindley in 1818, the second, Charles William in 1820, and finally Mary Rodman in 1822.
