LeGrande Survey of 1833. Made in era of Mexico rule in Texas for John Beales, who through partnerships, acquired 70,000,000 acres of land and gained the title of "Texas" largest land king. Alexander LeGrande's survey covered about 2,000 miles in west Texas, Oklahoma Panhandle and Eastern New Mexico then south to the 32nd parallel. Hardship and tragedy plagued LeGrande's abandoned survey. First exploration here is usually credited to Capt. R. B. Marcy, U.S. Army; LeGrande's work was years earlier. #3055
