to the army on business, were my companions on the journey.
The Colorado, as I have already said, is nearly eighty
miles distant: and as we travelled slowly, we were two days
and a half on the road. The whole line of country deserves
scarcely a better name than that of a desert. Water is found
only in two small wells; it is called fresh; but even at this
time of the year, during the rainy season, it was quite brackish.
In the summer this must be a distressing passage; for
now it was sufficiently desolate. The valley of the Rio
Negro, broad as it is, has merely been excavated out of the
sandstone plain; for immediately above the bank on which
the town stands, a level country commences, which is interrupted
only by a few trifling valleys and depressions. Everywhere
the landscape wears the same sterile aspect; a dry
gravelly soil supports tufts of brown withered grass, and
low scattered bushes, armed with thorns.

Shortly after passing the first spring we came in sight of
a famous tree, which the Indians reverence as the altar of
Walleechu. It is situated on a high part of the plain; and
hence is a landmark visible at a great distance. As soon as a
tribe of Indians come in sight of it, they offer their adorations
by loud shouts. The tree itself is low, much branched,
and thorny: just above the root it has a diameter of about
three feet. It stands by itself without any neighbour, and
was indeed the first tree we saw; afterwards we met with a
few others of the same kind, but they were far from common.
Being winter the tree had no leaves, but in their place
numberless threads, by which the various offerings, such as
cigars, bread, meat, pieces of cloth, etc., had been suspended.
