In pursuance of previous adjournment, the two commissioners met this day at the office of 

 the joint commission. Seilor Salazar stated that after he separated from Mr, Emory on llie 

 20th August, 1855, he reviewed with his parties the difTerent lines of the Lianulary ; that is to 

 say, the paralhl 31^ 47', the meridian, ami tlie puralkd 31° 20', on which lines the ^^loxican 

 commission executed the following work : 



From the point south of El Carrizalillo, on which was erected a monument, he oLiscrvi'd 

 minutely on Polaris to determine the prime vertical on hoth sides, cast and west. The prlnio 

 vertical and the parallel 31° 47' were connected hy a trlanguIiUion — on the east side with tliat 



which had been made at the initial point, and on the west side with the intersection of meri- 

 dian. "Hy this triangulation five points to the east were fixed, at which points he caused to he 

 erected monuments of stone, with mortar, hccause he found not one established by the United 

 States commission in said direction. 



The monument at the road was reconstructed of stone, with mortar. Upon all of tb(Mn w.m 

 InscriLod the abridged inscription agr^'od upon. This line wa^^ then marked with ton monu- 

 ments, Tliat at the west end he caused to be erected of dressed stone with mortar, and 

 inscribed with the complete inscription agreed upon, similar to that which was erected at tlio 

 initial point en the Rio Bravo. 



Mr. Salazar stated that lie observed at the south end of the meridian for latitude and lontri- 

 tude, his results differing very little from those of the United States commission ; that from 

 this point was carried north a triangulation which was connected at the north end with that 

 made on the parallel 31° 47', and was used to determine the position of said end on the parallel 

 and on the meridian ; that these two extreme points were left where tlie United States com- 

 mission established them ; that having found no monument l>etween them, he caused one to be 



erected intermediate, in sight of the Ojo de los Mosquitos, of dressed stone laid in mortar, with 

 the usual inscriptions ; that the monument at the south end was erected of dressed stone and 

 mortar with inscriptions similar in all respects to those at the north end and at the initial point. 

 On the parallel 31*^ 20', besides the observations he made at the intersection, he observed for lati- 

 tude at San Luis springs, at San Bernardino, and San Pedro river ; he found monuments at the two 

 first named points, but none at the last ; that his observations proved that the points were on 

 the parallel 31° 20', and he caused monuments to be erected at these points with mortar, 



w 



having the usual inscriptions upon them, and that he thought it proper to erect a monument 

 of the same kind in Guadalupe Pass. 



Mr. Emory stated his entire satisfaction with what bad been done by Mr. Salazar, and gave 

 his assent thereto, except with regard to the monument at San Pedro river. He desired to call 

 in Mr. Weyss, who was with Mr. Von Hippel when the monument was erected on the San Pedro. 

 His own recollection was, that a very substantial monument had been erected at the San Pedro 

 by the United States commission. 



Mr. "Weyss was brought before the commissioners, and stated that a monument of dressed 

 stone, with the usual inscription, was erected on the parallel 31° 20', three thousand eight 

 hundred and twenty-five feet west of the San Pedro river. The maps and views were exhibited 

 showing the exact locality of this monument, Mr. Emory stated, if the Indians had destroyed 

 that monument it was all very well ; but if it was still standing, there might be some discrep- 

 ancy, amoimting, possibly, to 1" of arc, or one hundred feet between the latitude of the monu-
