The river was at flood and we had an easy time of it so far as travelling was concerned.

Our investigations and photographing sometimes consumed half a day, but in the other half we made good progress, eight or nine miles without trying.

The rations were limited in variety, but were abundant of their kind, being almost entirely bread and black coffee.

When we tried, we made great runs, one day easily accomplishing about forty miles.

The San Juan was now a powerful stream, as we saw on passing.
