but impossible if the standard maps were correct. But this was not all. It seemed that this river of 1,000 kilometres in length was really the true upper course of the Aripuanan proper, in which case the total length was nearly 1,500 kilometres.

Since then the Castanho had fallen; our measurements showed it to be slightly smaller than the other; the volume of the river after the junction was about 4,500 cubic metres a second. This was in 7° 34´.
We were glad indeed to see Pyrineus and be at his attractive camp. We were only four hours above the little river hamlet of São João, a port of call for rubbersteamers, from which the larger ones go to Manaos in two days. These steamers mostly belong to Senhor Caripe. From Pyrineus we learned that Lauriadó and Fiala had reached Manaos on March 26.
