attacks the aggressor with rage proportioned to the pain of the wound. On this account, whenever any of those beasts are to be destroyed, many men armed with spears unite together; the use of the musket alone is almost always dangerous; for unless the tiger is knocked down by the first ball, he leaps furiously to the place whence the fire proceeded, and tears the man that inflicted the wound. He, therefore, that does not choose to run the risk of his life, goes accompanied on each side by two spearmen, who pierce the tiger as it advances to attack him, after he has fired his musket. Taught by the danger of others, I found that bullets must not be rashly used against tigers. Travelling with six Mocobios, from the city of Santa Fè to the town of St. Xavier, I passed the night on the banks of the round lake, in the open air, as usual; the earth was our bed, the sky our covering. The fire, our nightly defence against tigers, shone for a while in the midst of us as we slept, but at length grew very low. In the middle of the night a tiger crept towards us. My Indian companions, that they might not appear distrustful of the friendship of the Spaniards, had begun the journey unarmed. Anticipating no danger, I had neglected to load my musket. At my direction, firebrands were dexterously hurled at the approaching tiger. At each throw he leapt back roaring, but resumed courage, and returned again and again, more threatening than before. Meantime I loaded my musket. But as the darkness deprived me of all hope of killing the tiger, and left me only the desire to escape, I loaded my musket with plenty of shot, and fired it off without a ball. The beast, alarmed at the horrid thundering, instantly fled, and we lay down to sleep again, rejoicing in our success. Next day, at noon, in a narrow path, bounded on one side by a lake, and on the other by a wood, we met two tigers, which would have been caught with a noose by the pursuing Mocobios, had they not fled and hidden themselves in the wood.
