You have hit upon a little known piece of American history. It's a result of a surveying error about 1860 and resulted in awarding almost 1,000 square miles of New Mexico land to Texas. It's a fun story to read and as a piece of obscure trivia you will be one of the few to know that some towns in west Texas (Farwell and Plains come to mind) really belong in New Mexico. Enjoy:
