Embarked on board the Balandra; a one masted vessel of a hundred tuns; we made sail down the current. The weather continuing bad, we only went a few leagues & fastened the vessel to the trees on one of the islands. The Parana is full of islands; they are all of one character, composed of muddy sand, at present about four feet above the level of the water; in the floods they are covered. An abundance of willows & two or three other sorts of trees grow on them, & the whole is rendered a complete jungle by the variety & profusion of creeping plants. These thickets afford a safe harbour for many capinchas & tigers. The fear of these latter animals quite destroyed all pleasure in scrambling in the islands. On this day I had not proceeded a hundred yards, before finding the most indubitable & recent sign of the tiger. I was obliged to retreat; on every islands there are tracks; as in a former excursion the "rastro" of the Indians had been the constant subject of observation, so in this was the "rastro" del tigre".
The jaguar is a much more dangerous animal than is generally supposed: they have killed several wood-cutters; occassionally they enter vessels. There is a man now in the Bajada, who coming up from below at night time was seized by a tiger, but he escaped with the loss of the use of one arm. When the floods drive the tigers out of the islands; they are most dangerous, a few years since a very large one entered a church at St Fe. Two padres entering one after the other were killed, a third coming to see what was the cause of their delay, escaped with difficulty. The beast was killed by unroofing one corner of the room & firing at it. The tigers annually kill a considerable number of young oxen & horses. These islands undergo a constant round of decay & renovation. In the memory of the master several large ones had disappeared, others again had been formed & protected by vegetation.
