When I was reading through the newspaper pages I found these interesting ads which tell a lot about the importance of the local mill and who their agents were. Here are the details of the newspaper, etc...
THE ISLANDER, Or Prince Edward Island Weekly Intelligence and Advertiser,
Vol. XXII, Charlottetown, Friday, September 16, 1864. No. 1126
Below is an image from page 129 of Meacham's 1880 Atlas of Prince Edward Island. The world famous Stanfield's Underwear had it's beginnings here on Prince Edward Island at this mill in Tryon.
For more information about Stanfields go to: http://www.stanfields.com/ . The following is from their website:
Charles E. Stanfield had no idea when he immigrated to Canada in 1855 that he would found the firm that is a leader in its field today. Charles, along with his brother-in-law, Samuel E. Dawson, founded the Tryon Woolen Mills in Tryon, P.E.I. in 1856. Ten years later he sold his interests to Samuel and moved to Nova Scotia where he founded the Truro Woolen Mills in 1870. It was believed to be the first factory of its kind in Canada.
