One of the many large brick mills in Millbury, the S&D Spinning Mill (originally Singletary Mill) sits on Singletary Brook, which historically provided power for the facility. The four-story mill building was constructed in 1846 and is believed to be the oldest extant mill structure in town. Beginning in the late 1820s, successive textile mills used the waterpower here, including the companies: Singletary Manufacturing Company, the Boston & Millbury Company, and Farnum & Jenks. Fires destroyed all mills on this site, sometimes within just a couple years of each other. The last mill was destroyed in 1846, and Mowry Farnum, who owned the site, rebuilt a brick mill here, which is what we see today. After a couple companies occupied the building, the Mayo Woolen Company (which was featured on here previously) purchased this mill in 1910, and renamed the structure Mayo Mill No. 2. In 1961 a newly formed company, S&D Spinning Mill Inc. occupied the building. They are best-known today as the sole-manufacturer of the yarn which fills Major League Baseballs! Manufacturing is not dead in New England!
