of mice alone I obtained no less than eight kinds. [4] The
largest gnawing animal in the world, the Hydrochaerus capybara
(the water-hog), is here also common. One which I
shot at Monte Video weighed ninety-eight pounds: its
length from the end of the snout to the stump-like tail, was
three feet two inches; and its girth three feet eight. These
great Rodents occasionally frequent the islands in the mouth
of the Plata, where the water is quite salt, but are far more
abundant on the borders of fresh-water lakes and rivers.
Near Maldonado three or four generally live together. In
the daytime they either lie among the aquatic plants, or
openly feed on the turf plain. [5] When viewed at a distance,
from their manner of walking and colour they resemble pigs:
but when seated on their haunches, and attentively watching
any object with one eye, they reassume the appearance
of their congeners, cavies and rabbits. Both the front and
side view of their head has quite a ludicrous aspect, from
the great depth of their jaw. These animals, at Maldonado,
were very tame; by cautiously walking, I approached within
three yards of four old ones. This tameness may probably
be accounted for, by the Jaguar having been banished for
some years, and by the Gaucho not thinking it worth his
while to hunt them. As I approached nearer and nearer
they frequently made their peculiar noise, which is a low
abrupt grunt, not having much actual sound, but rather arising
from the sudden expulsion of air: the only noise I know
at all like it, is the first hoarse bark of a large dog. Having
watched the four from almost within arm's length (and they
me) for several minutes, they rushed into the water at full
gallop with the greatest impetuosity, and emitted at the
