delineated. 1
The whole map is exceedingly minute, and the
localities mostly correctly named, but there are
some errors of position, both absolute and relative,
such that I suppose the map to have been con-
structed mainly from a simple view of the country,
and that no angles and very few compass-bearings
have been taken. The margins of the map correspond
so nearly with the actual parallels and
meridians, that they may be assumed to represent
the cardinal points of the compass, as on an
ordinary map, without sensible error.
The country represented extends from Cotopaxi
on the north to the base of Tunguragua on the
south, and from the plain of Callo (at the western
foot of Cotopaxi) on the west to the river Puyu, in
the forest of Canelos, on the east. It includes an
area of something less than an equatorial degree,
namely, that comprised between o 40' and i 33'
S. lat., and between o 10' \V., and near o c
50' E.
of the meridian of Quito. In this space are re-
presented six active volcanoes (besides Cotopaxi),
viz.-
i. El Volcan cle los Mulatos, east a little south
from Cotopaxi, and nearly on the meridian of the
Rio cle Ulva, which runs from Tunguragua into the
Pastasa. The position of this volcano corresponds
to the Quilindana of most maps a name which
does not occur on Guzman's, nor is it known to any
of the actual residents of the country. A group of
mountains running to north-east, and terminating in
