Now they reach the crest of the spur , and , passing over it , still travelling in an easterly direction , descend into the valley beyond until they reach the margin of a small stream flowing northward . Here they pause in the shadow of an enormous granite rock of very remarkable appearance , for it bears a most extraordinary resemblance to the head and neck of an Indian -- I know it well ; and among us it is called ` The Inca 's Head ' . They sit down beneath this rock and proceed to eat and drink -- for it is now two hours past midday -- binding the Englishman 's feet and releasing his hands to enable him to feed himself . Now the meal is over , and the party resume their march , going northward along the western bank of the stream and plunging ever deeper into the valley . The soil here is once more rich and fertile , being overgrown with long , rank grass -- through which they leave a trail easy to follow -- and dense masses of mimosa and other bush . Now it is evening , the valley grows dark , and the party prepare to camp for the night ; they have found a suitable spot , quite close to the river bank , and are lighting a large fire .
