 ORGANIZATION OF THE INTERNATIONAL BOUNDARY COMMISSION. 



Under the provisions of the convention of July 29, 1882. revised 

 by that of February 18, 1889, between the United States and Mexico, 

 providing for an International Boundary Survey to re-locate the exist- 

 ing frontier line between the two countries west of the Rio Grande, 

 the President of the United States directed the appointment of Lieut. 

 Col. J. W. Barlow. Corps of Engineers; First Lieut. David I). (Tail- 

 lard, Corps' of Engineers; and Mr. A. T. Mosman, assistant, United 

 States Coast and Geodetic Survey, members of a commission, who, 

 with corresponding appointees of the Mexican Government, should 

 form an International Boundary Commission to carry into effect the 

 provisions of those conventions. Senor Don Jacobo Blanco, engineer 

 in chief, and Senores Felipe Valle and Jose Tamborrel, associate 

 engineers, were appointed on the part of Mexico, but they subse- 

 quently withdrew from the Commission and their places were filled 

 by the appointment of Senores Valentin Gama and Guillermo B. y 

 Puga. The first meeting, all of the members being present, was held 

 at the Mexican custom-house in Juarez on November 17, 1891, when 

 the International Boundary Commission came into formal existence. 

 Complete organization of the personnel, transportation, and camp 

 equipage of the surveying parties was effected subsequently. 



The Mexican and American parties had separate organizations and 

 worked independently in the field, though frequently passing one 

 another or camping in juxtaposition. On taking the Held at El Paso. 

 Texas, in February, L892, the United States party consisted of the 

 three commissioners and about 60 civilian employees, with a trans- 

 portation outfit of seven 4-mule baggage wagons, three 6-mule water- 

 tank wagons, three 2-mule light spring wagons, one 2-mule buck- 

 Jboard, one 4-mule ambulance. 25 mules for packing, 83 mules in all,
