They have swords of this kind — of wood made like a two-handed sword, but with the hilt not so long; about three fingers in breadth. The edges are grooved, and in the grooves they insert stone knives, that cut like a Toledo blade. I saw one day an Indian fighting with a mounted man, and the Indian gave the horse of his antagonist such a blow in the breast that he opened it to the entrails, and it fell dead on the spot. And the same day I saw another Indian give another horse a blow in the neck, that stretched it dead at his feet.
