“What mountains are those?” I inquired of a barber-surgeon, who, mounted like myself on a grey burra, joined me about noon, and proceeded in my company for several leagues. “They have many names, Caballero,” replied the barber; “according to the names of the neighbouring places so they are called. Yon portion of them is styled the Serrania of Plasencia; and opposite to Madrid they are termed the Mountains of Guadarama, from a river of that name, which descends from them; they run a vast way, Caballero, and separate the two kingdoms, for on the other side is Old Castile. They are mighty mountains, and though they generate much cold, I take pleasure in looking at them, which is not to be wondered at, seeing that I was born amongst them, though at present, for my sins, I live in a village of the plain. Caballero, there is not another such range in Spain; they have their secrets too—their mysteries—strange tales are told of those hills, and of what they contain in their deep recesses, for they are a broad chain, and you may wander days and days amongst them without coming to any termino. Many have lost themselves on those hills, and have never again been heard of. Strange things are told of them: it is said that in certain places there are deep pools and lakes, in which dwell monsters, huge serpents as long as a pine tree, and horses of the flood, which sometimes come out and commit mighty damage. One thing is certain, that yonder, far away to the west, in the heart of those hills, there is a wonderful valley, so narrow that only at midday is the face of the sun to be descried from it. That valley lay undiscovered and unknown for thousands of years; no person dreamed of its existence, but at last, a long time ago, certain hunters entered it by chance, and then what do you think they found, Caballero? They found a small nation or tribe of unknown people, speaking an unknown language, who, perhaps, had lived there since the creation of the world, without intercourse with the rest of their fellow creatures, and without knowing that other beings besides themselves existed! Caballero, did you never hear of the valley of the Batuecas? Many books have been written about that valley and those people. Caballero, I am proud of yonder hills; and were I independent, and without wife or children, I would purchase a burra like that of your own, which I see is an excellent one, and far superior to mine, and travel amongst them till I knew all their mysteries, and had seen all the wondrous things which they contain.”
