Besides a perfect tooth of the Toxodon, and many scattered bones, I found two immense skeletons near each other, projecting in bold relief from the perpendicular cliff of the Parana.

They were, however, so completely decayed, that I could only bring away small fragments of one of the great molar teeth; but these are sufficient to show that the remains belonged to a Mastodon, probably to the same species with that which formerly must have inhabited the Cordillera in Upper Peru in such great numbers.

The men who took me in the canoe said they had long known of these skeletons, and had often wondered how they had got there: the necessity of a theory being felt, they came to the conclusion that, like the bizcacha, the mastodon was formerly a burrowing animal! In the evening we rode another stage, and crossed the Monge, another brackish stream, bearing the dregs of the washings of the Pampas.
OCTOBER 2, 1833.
We passed through Corunda, which, from the luxuriance of its gardens, was one of the prettiest villages I saw.

From this point to St.Fe the road is not very safe.

The western side of the Parana northward ceases to be inhabited; and hence the Indians sometimes come down thus far, and waylay travellers.
