From The Story of Dartmouth, by Dr. John P. Martin:
This photo of Sterns’ corner taken about 1930, shows the Governor Wentworth cannon in the same position as seen today near the Portland Street show-window of Dartmouth Furnishers, Ltd. The other large structure two doors north was the first brick building: of Dartmouth, erected by Luther Sterns as a store and dwelling about 1864. In a section of his dry-goods establishment, was the local Post Office. One of Dartmouth’s famous residents who called in for morning mail was the great Joseph Howe.
