In mid-afternoon we came to the mouth of a big and swift affluent entering from the right. It was undoubt- edly the Bandeira, which we had crossed well toward its head, some ten days before, on our road to Bono- facio.

On the sheer banks where ’we Handed we had to push the canoes for yards or rods ^through the branches of the submerged trees, hacking and hewing. There were occasional bays and ox-bows from which the current had shifted. In these the coarse marsh grass grew tall.
