The records in this collection cover a ten year period from 1916 through 1926 but the bulk of the collection consist of business correspondence between 1922 and 1924. There were apparently a couple of lumber companies to call themselves the San Augustine County Lumber Company (according to W. T. Block in his book East Texas Mill Towns and Ghost Towns). These records represent Angelina County Lumber Company which was formerly San Augustine County Lumber Company. There are several items of correspondence which bear the Angelina County Lumber Company name.
