scent, was a mquntain of peculiar symmetry, resembl.ng the seg- 
ment of a spheroid. I named it ‘tthe Dome”. Our road led along 
its base to the north; another path leading to Janos, a frontier town 
. in Sonora, passes down the:Mimbres on the south side. The 
Mimbres was traversed only a mile; for that distance its valley 
was truly beautiful, about one mile wide of rich fertile soil, densely 
covered with cotton wood, walnut, ash, &c. It it is a rapid, dash- 
ing stream, about fifteen feet wide. and three deep, affording suffi- 
* cient water to irrigate its beautiful yalley. It is filled with trout. 
At this place we found numberless Indian lodges, which had the ; 
appearance of not having been occupied for sometime. We turned — 
westward and ascended all the way to our camp. a 
e mountains appeared to be formed chiefly of a reddish amyg- 
daloid and a brown altered sandstone, with chaledonic coating. In — 
places, immense piles of conglomerate protruded; disposed in regu- 
lar strata, dipping to the south at an angle of 45°. There wasalso 
one pile of volcanic glass brittle, in strata about a half an inch 
thick, dipping 45° to the south. The character of the coungey and 
ed 
its growth to-day are very similar to those of yesterday; several new 
plants and shrubs, amongst which was the cercocarpus parvifolius, 
a curious rosaceous shrub, “‘with a spiral, feathery tail, projecting 
from each calyx when the plant is in,seed.”” The spiral tailed or 
barbed seed-vessels fall when ripe, and, impelled by the wind, work 
into the ground by a gyratory motion. The cedar seen to-day was 
also very peculiar; in leaf resembling the common cedar of the _ 
‘ States, but the body like the pine, except that its bark was much — 
q rougher.. (For the rest of to-day’s growth, see catalogue of plants ©
