From the ridge on which Tizzano stands, which is the third of these Apennine spurs, to the next, the fourth, is but a little way; one looks across from one to the other. Nevertheless it is a difficult piece of walking, because in the middle of the valley another ridge, almost as high as the principal spurs, runs down, and this has to be climbed at its lowest part before one can get down to the torrent of the Enza, where it runs with a hollow noise in the depths of the mountains. So the whole valley looks confused, and it appears, and is, laborious. Very high up above in a mass of trees stood the first of those many ruined towers and castles in which the Apennines abound, and of which Canossa, far off and indistinguishable in the haze, was the chief example. It was called 'The Tower of Rugino'. Beyond the deep trench of the Enza, poised as it seemed on its southern bank (but really much further off, in the Secchia valley), stood that strange high rock of Castel-Nuovo, which the peasant had shown me that morning and which was the landmark of this attempt. It seemed made rather by man than by nature, so square and exact was it and so cut off from the other hills. It was not till the later afternoon, when the air was already full of the golden dust that comes before the fall of the evening, that I stood above the Enza and saw it running thousands of feet below. Here I halted for a moment irresolute, and looked at the confusion of the hills. It had been my intention to make a straight line for Collagna, but I could not tell where Collagna lay save that it was somewhere behind the high mountain that was now darkening against the sky. Moreover, the Enza (as I could see down, down from where I stood) was not fordable. It did not run in streams but in one full current, and was a true river. All the scene was wild. I had come close to the central ridge of the Apennines. It stood above me but five or six clear miles away, and on its slopes there were patches and fields of snow which were beginning to glimmer in the diminishing light. Four peasants sat on the edge of the road. They were preparing to go to their quiet homesteads, and they were gathering their scythes together, for they had been mowing in a field. Coming up to these, I asked them how I might reach Collagna. They told me that I could not go straight, as I had wished, on account of the impassable river, but that if I went down the steep directly below me I should find a bridge; that thence a path went up the opposite ridge to where a hamlet, called Ceregio (which they showed me beyond the valley), stood in trees on the crest, and once there (they said) I could be further directed. I understood all their speech except one fatal word. I thought they told me that Ceregio was _half_ the way to Collagna; and what that error cost me you shall hear.
