My de ar Mr. Eo 11 ard: 
Your letter is duly received. I will always 
be glad to give you what information 1 can respecting my plant gath 
erings on the boundary line. 
The San Luis Mountains constitute^together with their exten¬ 
sion, the Animas range of New Mexico,- the backbone of the Conti¬ 
nent. To the southward they connect with the Sierra Madre. The 
San Luis Mts. were spoken of in the old boundary report as the 
"Sierra Madre", but at the present day, they are always called the 
San Luis range, the Sierra Madre proper lying wholly south of the 
United States. 
Almost all of the plants and animals found in the San Luis 
are also found in the Animas range, of New Mexico. The San Luis 
in New Mexico, divides the Animas from the San Luis. The 
latter(San Luis) lies principally in Mexico, but its northern third 
(about) is in New Mexico. The specimens collected were practical¬ 
ly from the international line, or just south of it. All of the 
highest peaks were visited. Monument No. 65(rebuilt) of the new 
survey is on the highest point of the San puis Mountains crossed by 
the Mexican line. All of the highest peaks are south of the bound 
ary line crossing. The distance, on the boundary line from the 
middle ot the Rio Grande River to the monument on the summit of the 
San Luis Mts(65) is 5217&30 meters.
