Report on the boundary survey primarily "devoted to defending [Gray's] position in his conflict with John Bartlett, who seems to have trouble with everyone involved," as noted by Wagner-Camp. The report is perhaps more important for the accompanying maps, "Map of the Portion of the Boundary for the United States and Mexico, from the Pacific Coasts to the Junction of the Gila and Colorado Rivers...and the Rio Gila, from near its Intersection, with the Southern Boundary of New Mexico..." (54.6x124.7 cm.) and "That Part of Disturnell's Treaty Map in the Vicinity of the Rio Grande and Southern Boundary of New Mexico..." (22x27.5 cm.). The first details the American Southwest from Los Angeles east to the Rio Grande; both are quite important for studying the boundary survey.
