Boundary between Guatemala and Mexico

Oaxaca: Gabino Marquez, 1882. 225 by 155mm (8¾ by 6 inches). 8 vo. 112 pp. Original printed purple wrappers. In Spanish. 

Good; the front wrapper chipped with a portion of the top half torn away; wrappers barely holding. Cigarette burn to page 27 (through to page 28), not affecting text. 

An extensive discussion on the convention of December 7, 1877, over the Guatemala-Mexico border, which at that time was not settled. As a result of the convention a mixed group of Mexican and Guatemalan engineers were tasked with surveying and making plans for a definitive border. Later, after the surveyors failed to complete their work by 1879, the U.S. State Department played a vital role in defining the border by arbitrating the long-running dispute between the two countries. The treaty over the Guatemala-Mexico boundary was signed in New York City in 1882.
