VISIT TO ANTISANA. 
On the 3rd of August, M. Boussingault 
and myself, accompanied by Don Jose Val- 
divieso, set off to visit the farm and moun- 
tain of Antisana. Antisana is one of the 
peaks of the Eastern Cordillera, situated 
S. 75? E. from Quito, at the distance, in 
a straight line, of thirty miles. The road 
across the upper or southern part of the 
Valley of Chillo. We crossed the ridge of 
El Chasque to the village of Conocoto, dis- 
tant about two leagues, a little beyond 
which the rivers of San Pedro and Pite, 
having collected the streams from the head 
of the

em extremity of the hill of Y ylalo, from the

Pedro, or Alangusin. Though destitute of 
accommodations, they are frequented for 
their medicinal virtues; although from the 
analysis of M. Boussingault, it does not 
eem they possess any other than those of 
hot water. That of San Pedro, at the 
southern point of the hill, is surrounded 
by an Indian village, the inhabitants of 
which, by some happy casualty, have re- 
mained masters of the soil, and form, by 
their activity, industry, and comparatively 
easy circumstances, a pleasing contrast to 
the abject mass of the Indigenes. They 
have tiled houses, and live stock, and 
manufacture coarse linens, and other tri- 
fling articles with which they trade as far 
as Pasto and Barbacoas. The climate 
here is mild and agreeable ; the elevation 
of San Pedro is 8,470 feet. The tempe- 
rature of the spring is 101°, We continued 
our route across the valley, which is level, 
and cultivated. The ridge of Pasuchoa, 
with its rocky peaks, divides the head of it 
into two compartments, of which the west- 
ern rises gradually towards the heights of 
Tiopullo, while the eastern ascends to- 
wards the roots of Sinchulagua, and Ru- 
minavi. The latter was on a subsequent 
occasion the object of an excursion by Pro- 
fessor Jameson and myself, during a visit 
to the estate of Don Vicente Aguino. The 
most interesting object in it is the cascade 
of the Piti, which, descending from Sin- 
chulagua, precipitates itself perpendicu- 
larly about 150 feet, into a wooded glen. 
All this tract is covered with thickets, 
rising sometimes to the dignity of forests. 
We found several shrubs and trees we 
had not before seen, especially the tree 
named by the inhabitants El Olivo, from 
its supposed resemblance to the olive. Ve- 
getation here is favoured by the abundance 
of humidity. The clouds, collected on all 
the surrounding peaks, dissolve in abun- 
dant showers, or rather storms, accompa- 
nied by electric explosions, so numerous, 
that it seems to rain as much fire as water. 
A friend of mine once counted forty-three - 
in five minutes. These storms often de- 
scend Ps the valley, and extend to 
Quito, because Pichincha forms part of-
