midday
`` A lion is there , senhor , devouring the carcass from which he has driven the vultures away . '' In a short time the correctness of the youth 's observation was proved by the party coming upon , and driving away , a puma which had previously disturbed the vultures at their banquet on the carcass of an unfortunate ox . The next morning Pizarro 's capacity for tracking the wilderness was proved by the party coming on the broad trail of the troops . Soon afterwards they discovered the men themselves taking their midday siesta . Not long after that the united party came within scent of the Atlantic , and on the afternoon of the same day galloped into the town of Buenos Ayres . Descriptions , however graphic or faithful , are for the most part misleading and ineffective . Who ever went to a town or a region , and found it to resemble the picture of it which had been previously painted on his imagination by description ?
