1835 letter of Col. Nicholas Copeland to his son-in-law Martin Bridgman of Arkansas, enticing him to move to Texas. The letter discusses the price of land and cattle, as well as the profitability of crops such as cotton and corn. Copeland adds a note for Harry Currin, a free African-American, stating that Texas is a safe place to settle. His land grant (settlement & fortification) described in the letter was 25 miles west of the Trinity River just before crossing the Navasota River. This letter was written at Robbins' Ferry on the Old San Antonio Road at the crossing of the Trinity River (letters went east from there to be carried & put in the US mail system).
