The ordinary deciduous fruit trees are cultivated, of course with 
irrigation, very successfully, and the climate is sufficiently warm for 
the grapevine and sweet-potato to nourish. Cotton, however, though 
grown experimentally on the college farm at Las Cruces (and there 
attacked by Aletia), will not do sufficiently well to be worth cultivating 
for i)roflt. 
Thus, though the region is a warm one for the temperate zone, it can 
not by any means be described as subtropical or approaching thereto* 
All that can be said is that there are certain suggestions of the tropical 
region further south, e. g., the abundant presence of the neotropical 
butterfly (Synchloe lacinia) and the presence of some genera of Coccidse, 
such as Ceroplastes, Tachardia, and Prosopophora, which are rather 
neotropical than nearctic. 
2. Santa Fe, in the northern part of the Territory, watered by 
mountain streams (usually almost dry), about 7,000 feet above sea level. 
The comparatively cool summer forms a pleasant contrast to the Mesilla 
Valley, while the winter, although cold, is mild for a place of such 
altitude, owing to the protection afforded by surrounding forest-covered 
mountains and the general soutlrwest slope. 
As in the Mesilla Valley, the apple, peach, pear, plum, and apricot 
are successfully grown, though sometimes injured by late frosts. It 
is, perhaps, the only place in the United States where these fruits are 
grown at and above 7,000 feet, though I speak here without certain 
information of what may be done in Arizona and southern California. 
Some small fruits, such as raspberries, succeed excellently. The fig 
and the sweet-potato, which grow well in the Mesilla Valley, will not 
do in Santa Fe, and it is too high even for grapes, excepting one or 
two hardy varieties. 
Santa Fe, judged by its fauna and flora, is distinctly in what I 
have called the sub-alpine zone, but it is near the upper limit. In 
Colorado I had considered the mid alpine to go down to about 0,500 
feet, though from lack of positive information this was only supposed 
to be an approximation to the truth. Probably it was very nearly cor- 
rect for Custer County, Colo., since we find at Santa Fe (7,000 feet), 
the upper limit of the sub-alpine, the more southern latitude and the 
southwestern exposure accounting for the extra 500 feet. 
At such an altitude one would expect at least some mid-alpine fea- 
tures, and on the whole I have been surprised that they are not more 
prominent than observation has shown them to be. At the same time, 
one sees at once strong differences from the fauna and flora of the 
Mesilla Valley, which will necessitate further subdivision of the sub- 
alpine zone, doubtless on such lines as have been already indicated by 
Dr. Merriam and Mr. Coville for points farther west. Thus, what may 
be termed the region of Solatium elceagnifolium extends up the Rio 
Grande Valley from El Paso to Albuquerque, but at Santa Fe this 
conspicuous roadside Solanum is wanting. Here, in its place, one meets
