level. 
‘The fall of the Rio Grande, from the northern border of the Terri- 
tory to the point where it cuts the New Mexico, Texas, and Chihuahua 
boundaries, is about 3,500 feet. The ranges generally rise from 2,000 
to 5,000 feet above the mesas and high table-lands. Mount Baldy, 18 
miles from Santa Fé, is 12,202 feet high; Mount Taylor, in the Sierra 
Mateo, is 11,200 feet high. ; 
The Rio Grande, Rio Pecos, Canadian, and San Juan are the princi- 
pal rivers of the Territory. The first rises in the mountains of southern 
Colorado, crosses the northern border of New Mexico at a central point, 
and follows a nearly direct course through the Territory to its southern 
boundary. This stream is not navigable at any point within the Ter- 
ritory. The valley of the Rio Grande, having an average width of 
8 or 9 miles and a length of about 400, includes large areas of most ex- 
cellent farming and fruit iands. The Rio Pecos, a large affluent of the 
Rio Grande, drains the mideastern and southeastern portions of the 
Territory, and the Canadian River and its tributaries the northeastern 
portion. The western part is drained by the San Juan, Zuiii, Gila, 
and other affluents of the Colorado River of the West. No lakes of | 
considerable size have as yet been discovered in the Territory. 
The water-courses of New Mexico, compared with those of her north- 
ern neighbor, Colorado, are few and of small volume. In the last- 
named State at least ten large and powerful rivers rise in the central 
mountain region, and, re-enforced by numerous tributaries, pass to and 
beyond the borders of the State. In New Mexico but two rivers, the 
Rio Grande and Rio Pecos, flow for a considerabie distance within the 
limits of the Territory. The two other important streams, the Rio San 
Juan and Canadian, flow, respectively, through the northwestern and 
northeastern corners of the Territory. The San Juan River, as well as 
the Rio Grande, rises in southern Colorado. 
‘‘Tt is not uncommon for a river to be considerably larger toward its 
source than at its mouth. Many of the important streams that flow 
from the Black Hills into the Missouri are lost on their way through 
the plains; this is especially the case with rivers in the arid regions of 
New Mexico and Arizona.” 
The high mountains of the Main Range extend southward into New 
Mexico for a distance of about 100 miles, reaching the neighborhood of 
Santa Fé. South of this there is a semi-tropical region. ‘There is of 
necessity a wide difference in the extremes of temperature, but with the 
exceptions of the cold seasons of the higher lands at the north, the 
climate is temperate and equable. The summer days in the lower 
valley are sometimes quite warm, but as the dry atmosphere rapidly 
absorbs the perspiration of the body, it prevents the debilitating ef- 
fect experienced where the air is heavier and more saturated with 
moisture. The nights are cool and refreshing. The winters, except iu 
the mountains at the north, are moderate, but the difference between
