Upon Asking At A House
Whether Robbers Were Numerous, I Was Answered, "The Thistles
Are Not Up Yet;" - The Meaning Of Which Reply Was Not At
First Very Obvious.
There is little interest in passing over
these tracts, for they are inhabited by few animals or birds,
excepting the bizcacha and its friend the little owl.
The bizcacha [1] is well known to form a prominent feature
in the zoology of the Pampas. It is found as far south as
the Rio Negro, in lat. 41 degs., but not beyond. It cannot,
like the agouti, subsist on the gravelly and desert plains of
Patagonia, but prefers a clayey or sandy soil, which produces a
different and more abundant vegetation. Near Mendoza, at
the foot of the Cordillera, it occurs in close neighbourhood
with the allied alpine species. It is a very curious
circumstance in its geographical distribution, that it has never
been seen, fortunately for the inhabitants of Banda Oriental, to
the eastward of the river Uruguay: yet in this province there
are plains which appear admirably adapted to its habits.
The Uruguay has formed an insuperable obstacle to its
migration: although the broader barrier of the Parana has
been passed, and the bizcacha is common in Entre Rios, the
province between these two great rivers. Near Buenos Ayres
these animals are exceedingly common. Their most favourite
resort appears to be those parts of the plain which during
one-half of the year are covered with giant thistles, to the
exclusion of other plants.
