HISTORY. References to a spring house appear frequently in descriptions of Green Spring Farm during the nineteenth century.[103] The well watered character of the farm, possessing springs of its own and traversed by Turkey Cock Run, was an advantage of great value to all its owners. Quite possibly the presence of the springs was decisive in enabling both the Mosses and Fountain Beattie to make dairying a substantial part of the farm's operations. In the 1830's, many of the types of equipment and utensils typically used in making and preserving butter, cheese, and fresh milk were listed in inventories of personal property at the farm. During this period and later, the presence of the Little River Turnpike would have made it feasible to sell dairy products regularly in Alexandria, six miles away, and in the District of Columbia, nine miles away.[104] It is equally likely that a spring house was also one of the focal points of the farm's cider and brandy-making activities at those times when the orchards flourished. After the sale of the farm by Fountain Beattie in 1917, the level of its operations gradually decreased. By 1940, the spring house stood unused, as neither dairying nor orchard activities were carried on. Therefore, when the Straights ordered the renovation of the main house in 1942, it was suggested that the spring house be converted into a residence for the farm's caretaker. Conversion of the spring house into a residence was carried out under the direction of Walter Macomber of Washington, D.C., who also had been in charge of remodeling the main house. Using the basic stone shell of the house, which was structurally sound, a two-story house was designed with living room, bedroom, kitchen, and utility (heater) room on the first floor and a bedroom, bathroom, and storage area on the second floor.[105] (See figure 19.) In this work, new materials were used, except that slate shingles taken from the main house (where the roof was being replaced) were used for roofing the spring house. In 1961, the second major remodeling of the house enlarged it and attempted to reduce the dampness due to its location in the midst of the springs. The architects for this work were Keyes, Lethbridge & Condon of Washington, D.C. As a result of this work, the roof was raised to permit construction of a new bedroom and storage room on the second floor. On the first floor, enclosure of a porch permitted the addition of a bathroom and closet to the downstairs bedroom. Substantial remodeling of the kitchen was also undertaken, in which a closet was converted into cabinets, new flooring was laid, and new kitchen fixtures were installed.
