March 31st. (92) A contrary wind forced us to stay on the river bank until midday. We saw a part of the cane fields devastated by a fire spreading from a nearby forest. Nomadic Indians set the forest alight everywhere they set up camp for the night; during the dry season vast provinces would be in flames if it was not for the extreme hardness of the wood, which does not completely burn. We found trunks of desmanthus and mahogany (cahoba) that were hardly burned more than 2 inches deep.
