FIRST EDITION, Senate issue, of what is considered “one of the most significant of all government reports on western and southern Texas” (Jenkins). Emory was tasked with determining the official American-Mexican boundary line, which still remains largely unchanged 150 years after his original survey, which is considered one of the most important surveys ever conducted. “This extensive report is the foundation work on the exploration and mapping of the United States-Mexico border” (Reese).
