. . . In the year 1907 he built a new home for the store -- a large modern, three-story, fire resistant structure. In the early ninteen-hundreds, Ambrose, in partnership with first E. M. Letts and second James L. Brenchley, engaged in the business of lumber manufacture. The partnerships purchased tracts of virgin timber in Pennsylvnia and New York and carried out the entire process from cutting the trees to selling the lumber in the wholesale markets of the county [country?].

In 1895 Ambrose built a house at Shunk in which he and family lived from 1895 until 1915. George Hine, then owner of the house, in the autumn of 1961, had a new roof installed. The wood shingles removed from the north slope of the house roof were the original ones placed in 1895, thus a remarkable roof life of 65 plus years. In 1895, in the Shunk area, shingles were made by handshaving rather than sawing as in some places. This method yielded shingles split with the grain of the wood, "straight grain," which accounts for the long service.

Ambrose sold the store in 1915. In the autumn of that year, he removed to Utica, New York, where he entered a partnership in a lumber and building supplies company trading in the name of Shiffer Lumber Company. The company failed, resulting in considerable financial loss to Ambrose E. Following liquidation of the company, Ambrose developed a lumber sales service by which he was sales representative in the Utica area for several lumber producers. During the late 1930s he gradually gave up work activity for retirement. He died 27 February 1932 in the Homeopathic Hospital, Utica, New York, and is buried in West Hill Cemetery, Shunk, Sullivan County, Pennsylvania.
