After this "aside," which explained the secret motive for the murder he had just committed in so rude a manner, the captain took upon his shoulders the body of the Guaycurus, and concealed himself with it in the thicket, from which he had so skilfully drawn his enemy. The reader must not conclude, from what we have just related, that the captain was a ferocious and sanguinary man. Don Diogo enjoyed amongst his companions a merited reputation for kindness and humanity, but the circumstances in which he was placed at that moment were exceptional. It was evident that if the Guaycurus spy, whom he had surprised and so pitilessly killed, had perceived him first, he would have stabbed him without hesitation. For that matter, the captain had taken care to say as much himself to the marquis. The war which was commencing was one of treachery and ambush. Time was precious; he therefore hastened to despoil his victim, in whose vestments he clothed himself. By a fortunate coincidence the two men were about the same size. The Indians possess a particular talent, not only for personation, but even put themselves into the very skin of those whose features they wish to borrow. With very trifling exceptions, the painting of the Guaycurus chiefs is all the same, and as their bearing differs very little, when an Indian of pure race assumes their costume, he easily attains a complete disguise. In a few instants the dead man was despoiled; only the captain took care to place under the enemy's poncho his own pistols and knife. After having carefully concealed his own vestments in a hole which he dug for that purpose, the captain assured himself that profound silence reigned around him; then, reassured or nearly so, he took the corpse again upon his shoulders, attached a large stone to its neck, to prevent it from floating, and, carefully separating the branches of the thicket (the roots of which were planted in the water), he pushed it gently into the river, without making the least noise. This delicate operation terminated, the captain glided again into the thicket, with a smile of satisfaction. Two hours thus passed away, during which the mysterious silence of the desert was not disturbed. Diogo began to weary of the length of his task; he was seeking some means of bringing it to an end, and of joining the Guaycurus, who could not, in all probability, be far removed, when a slight trembling of the dry leaves awakened his attention. He soon perceived the step of a man who was approaching him; this man, although walking cautiously, did not appear to think the situation dangerous enough to demand great precautions--hence this trembling which, slight as it was, had not escaped the delicate and experienced ear of the captain. But what was this man, and what did he want? These questions that Diogo addressed to himself, and which were impossible for him to answer, only resulted in alarming him seriously for his personal safety.
