here had the four necessaries of life "en el campo," -- pasture
for the horses, water (only a muddy puddle), meat and
firewood. The Gauchos were in high spirits at finding all
these luxuries; and we soon set to work at the poor cow. This
was the first night which I passed under the open sky, with
the gear of the recado for my bed. There is high enjoyment
in the independence of the Gaucho life -- to be able at any
moment to pull up your horse, and say, "Here we will pass
the night." The death-like stillness of the plain, the dogs
keeping watch, the gipsy-group of Gauchos making their
beds round the fire, have left in my mind a strongly-marked
picture of this first night, which will never be forgotten.

The next day the country continued similar to that above
described. It is inhabited by few birds or animals of any
kind. Occasionally a deer, or a Guanaco (wild Llama) may
be seen; but the Agouti (Cavia Patagonica) is the commonest
quadruped. This animal here represents our hares. It
differs, however, from that genus in many essential respects;
for instance, it has only three toes behind. It is also nearly
twice the size, weighing from twenty to twenty-five pounds.
The Agouti is a true friend of the desert; it is a common
feature of the landscape to see two or three hopping quickly
one after the other in a straight line across these wild plains.
They are found as far north as the Sierra Tapalguen (lat.
37 degs. 30'), where the plain rather suddenly becomes greener
and more humid; and their southern limit is between Port
Desire and St. Julian, where there is no change in the nature
of the country. It is a singular fact, that although the
Agouti is not now found as far south as Port St. Julian, yet
