From Ronco the path keeps level and then descends a little so as to cross the stream that comes down from Piora. This is near the village of Altanca, the church of which looks remarkably well from here. Then there is an hour and a half's rapid ascent, and at last all on a sudden one finds oneself on the _Lago Ritom_, close to the hotel. The lake is about a mile, or a mile and a half, long, and half a mile broad. It is 6000 feet above the sea, very deep at the lower end, and does not freeze where the stream issues from it, so that the magnificent trout with which it abounds can get air and live through the winter. In many other lakes, as, for example, the _Lago di Tremorgio_, they cannot do this, and hence perish, though the lakes have been repeatedly stocked. The trout in the _Lago Ritom_ are said to be the finest in the world, and certainly I know none so fine myself. They grow to be as large as moderate-sized salmon, and have a deep-red flesh, very firm and full of flavour. I had two cutlets off one for breakfast, and should have said they were salmon unless I had known otherwise. In winter, when the lake is frozen over, the people bring their hay from the farther Lake of Cadagna in sledges across the Lake Ritom. Here, again, winter must be worth seeing, but on a rough snowy day Piora must be an awful place. There are a few stunted pines near the hotel, but the hillsides are for the most part bare and green. Piora in fact is a fine breezy open upland valley of singular beauty, and with a sweet atmosphere of cow about it; it is rich in rhododendrons and all manner of Alpine flowers, just a trifle bleak, but as bracing as the Engadine itself. The first night I was ever in Piora there was a brilliant moon, and the unruffled surface of the lake took the reflection of the mountains. I could see the cattle a mile off, and hear the tinkling of their bells which danced multitudinously before the ear as fire-flies come and go before the eyes; for all through a fine summer's night the cattle will feed as though it were day. A little above the lake I came upon a man in a cave before a furnace, burning lime, and he sat looking into the fire with his back to the moonlight. He was a quiet moody man, and I am afraid I bored him, for I could get hardly anything out of him but "Oh altro"--polite but not communicative. So after a while I left him with his face burnished as with gold from the fire, and his back silver with the moonbeams; behind him were the pastures and the reflections in the lake and the mountains and the distant ringing of the cowbells.
