The property which now includes Edgewater was inherited by Isaac Cooper, the second son of Judge Cooper, on the death of his father in 1809. In the following year he began the erection of the house, which took nearly four years in building. Aside from its now venerable aspect, this solid residence, constructed of old-fashioned brick, preserves much of its original appearance as one of the largest dwellings in the village. It was modeled after a colonial residence in Philadelphia well known to the Cooper family. The style of the entrance hall, with the balanced symmetry of semicircular stairways that ascend to the upper floor, is singularly effective, while the carved wood of the interior, as seen in the doorcaps and mouldings, displays skillful workmanship. No house in Cooperstown commands so fine a general view of Otsego Lake as that which is to be seen from the porch of Edgewater. The surrounding ground includes over two acres, and extends to the waters of the lake, although now traversed by Lake Street, which made its way, by long usage, across the original property. The house is approached through the paths of an old time garden, thickly grown with shrubs, and shaded by a variety of trees. [Illustration: EDGEWATER] Isaac Cooper had married Mary Ann, daughter of General Jacob Morris, of Morris, Otsego county, and took possession of Edgewater as his residence on December 4, 1813. It is not difficult to understand the feeling of satisfaction, on being established in this beautiful home, which prompted Isaac Cooper, at the age of thirty-two years, to record the event in his diary thus: Moved--where I hope to end my Days--and I pray Heaven to allow this House and this Lot--whereon I this day brought my Family, to descend to my children and to my children's children, and may they increase in virtue and respectability, and become worthy of the blessings of Heaven. This diary is hardly more than a record of weather, with a single line of "general observations," under which head, from day to day, he makes brief mention of his doings, social engagements; births, marriages, and deaths among his friends; his own frequent illnesses: occasionally he moralizes, or indulges in a bit of self-criticism. A few entries selected from Isaac Cooper's diary will show its general character. It will be noticed that he refers to himself in the third person as "Mr. C." or "Mr. Cooper."
