Seeing no men, we sent two boats with Diego Mendez up the stream.

They were not gone a half league, when, watching from the _Consolacion_ we marked a strange and horrid thing.

There came without wind a swelling of the sea.
Our ships tossed as in tempest, and there entered the river a wall of sea water.

Meeting the outward passing current, there ensued a fury with whirlpools.

It caught the boats.
