Edwin Day, prominently known in the cotton industry and as the tax assessor of Runnels county, was born in Marshall county, Mississippi, in 1865, a son of T.P. Day, who came with his family to Fort Worth, Texas, in 1872, and he is still in business in that city, one of its best known pioneer citizens and business men. He was also one of the first jewelers of Fort Worth. The son Edwin was reared and educated in that city, and he lived there until coming to Ballinger in 1897. In that year he embarked in the cotton gin business in this city, establishing the third cotton gin to be built in Runnels county, and he took a prominent part in the developement of the great cotton industry therein that culminated in 1908 with wagon receipts at Ballinger of over fifty thousand bales, the highest record of any town in the United States. Mr. Day sold his individual interests in the cotton gin, but he is still connected with the industry as manager of the local gin owned by N.A. Perry and Company at Brownwood.
In 1906 he was chosen as the tax assessor of Runnels county, and as it is an unwritten law of the Runnels county Democracy to give an official when his duties have been well performed a second term. Mr. Day had no opposition in the recent primary and was regularly elected on the 3d of November, 1908, and he is now serving his second term. A man of high honor and unquestioned integrity, he has made a most efficient officer, a strong champion of the full rendition law. He is one of Ballinger's most progressive and best citizens.
He married in Fort Worth Miss Hattie McCamant, daughter of Captain J.D. McCamant, a well known pioneer citizen. He was born in Grayson county, Virginia, and coming to Texas in 1855 he located in Hunt county. He remembers visiting Fort Worth as early as 1857, when it was a small and very insignificant outpost, the only store there at the time being owned by Julius Field. Captain McCamant served two terms as clerk of Hunt county before the war, and at the outbreak of the conflict he joined McCulloch's Company of Texas Rangers and was in service on the frontier of Texas for protection against Indians. After twelve months of this service he returned to Hunt county and organized the company of which he was elected captain and reported for duty to General Albert Pike in the Indian Territory, and continued in service there during the remainder of the war. He lived in Fort Worth from about 1880 until 1885. In 1881 he made a trip to Jones county, and in 1885 moved there permanently, where he is engaged in the mercantile business at McCamant, the postoffice having been named in his honor.
Mr. and Mrs. Day have one child, Delia. The Day home is one of the beautiful residences of Ballinger, located on Broadway near the corner of Phillips street.
