'If we would ascend the highest member of the mountain group, the Monte Cavo, we must make the circuit of the north flank of the mountains of Marino, on the edge of the Albano Lake, and Rocca di Tassa, a picturesque village in the hollow mountain side, from which we climb through woods, abounding in _Galanthus nivalis_ and _Corydalis cava_, to that summit which was the _arx_ of Jupiter Latialis, and to which the thirty Latian cities ascended in solemn procession to offer their annual sacrifice. The place is now occupied by a convent, under the wall of which I gathered _Orinthogalum nutans_; and from its neighborhood I enjoyed a panoramic view, surely the most glorious, in its combination of natural beauty and grandeur of historical recollections, to be found anywhere on earth. The eye ranged from Terracina on one side to Veii on the other, and beyond Veii to the hills of Sutrium and Nepete, once covered by the Cimmian forests, then deemed an impenetrable barrier between the interior of Etruria and Rome. Below my feet the Alban mountain, with all its forest-covered folds, and in one of them the dark-blue Lake of Nemi; that of Albano, I think, was invisible. To the north, in the dim distance, the Eternal City, to the west the eternal sea, for eastern boundary, the long line of Sabine mountains from Soracte past Tibur and away towards Proeneste. The range then passed behind the Alban group, but re-appeared to the south-east as the mountain crescent of Cora and Pometia, enclosing between its horns the Pontine marshes, which lay spread out below as far as the sea line, extending east and west from Terracina in the bay of Fondi, the Volscian Anxur, to the angle of the coast where rises suddenly, between the marshes and the sea, the mountain promontory of Circeii, celebrated alike in history and in fable. Within the space visible from this one point, the destinies of the human race were decided. It took the Romans nearly five hundred years to vanquish and incorporate the warlike tribes who inhabited that narrow tract, but, this being accomplished, two hundred more sufficed them to complete the conquest of the world. During the frequent and latterly prolonged residence at Avignon, Mr. Mill, carrying on his botanical propensities, had become very well acquainted with the vegetation of the district, and at the time of his death had collected a mass of notes and observations on the subject. It is believed to have been his intention to have printed these as the foundation of a flora of Avignon.
