None of the other Alpine summits on Italian territory can compare in height with the Grand Paradis, for though the Italian language extends in numerous instances to the central chain of the Alps, the political boundaries of Italy do not. {191} Switzerland holds possession of the valley of the Upper Ticino, whilst Austria still possesses the Upper Adige. The only rivers rising on the southern slope of the Alps, and belonging in their entirety, or nearly so, to Italy, are the Tagliamento and the Piave. In consequence of this violation of the natural frontiers there are many snow-clad Alpine summits which, though geographically belonging to Italy, are situated on the frontiers of the present kingdom, or even within Swiss or Austrian territory. Amongst these are the giant summits of the Ortler, the Marmolade, and the precipitous Cimon della Pala. The Monte della Disgrazia, however, to the south of the Bernina, is an Italian mountain; such is also, for the greater part, the mountain mass of the Camonica, bounded on the north by the Pass of Tonale, which plays so prominent a part in legendary history, and is commanded by the Adamo, or Adamello, whose glacier streams creep down to the Upper Adige. Farther to the east, in the valley of the Piave, the obelisk surmounting the huge pyramid of the Antelao pierces the line of perennial snow, and there are other peaks scarcely inferior to it in height.
