Mark H. Salls poses with his daughter in his Rural Free Delivery wagon, circa 1912. Mr. Salls was the rural mail carrier for the town of Potsdam, Route #2. In the 1913 Potsdam Directory, he was listed as residing at 20 Garden St. with his wife, Nellie B. The name of his young daughter is not known. Rural Free Delivery was not widespread in the United States until 1902; prior to that, postal patrons residing in rural areas had to pick up mail themselves at distant post offices or pay private carriers for delivery. The rural delivery of mail uses a network of rural routes traveled by carriers such as Mr. Salls to deliver and pick up mail for free from the roadside mailboxes that are still familiar to us today. The Potsdam Public Museum submitted this photo. If anyone knows the location of the shot or the name of Mr. Sallss daughter, they are asked to contact themuseum at 265-6910 or firstname.lastname@example.org. The museum is located at 2 Park St. and is open from 10 a.m. to 4 p.m. Tuesdays through Saturdays.
