Its edges were so angular, and its size so great, that I at first mistook it for a rock in situ, and took out my compass to observe the direction of its cleavage.

The plain here was not quite so level as that nearer the coast, but yet it betrayed no signs of any great violence.

Under these circumstances it is, I believe, quite impossible to explain the transportal of these gigantic masses of rock so many miles from their parent-source, on any theory except by that of floating icebergs.
During the two last days we met with signs of horses, and with several small articles which had belonged to the Indians--such as parts of a mantle and a bunch of ostrich feathers--but they appeared to have been lying long on the ground.

Between the place where the Indians had so lately crossed the river and this neighbourhood, though so many miles apart, the country appears to be quite unfrequented.

At first, considering the abundance of the guanacos, I was surprised at this; but it is explained by the stony nature of the plains, which would soon disable an unshod horse from taking part in the chase.
