The plain of Lombardy is so broad, and the road to Milan by Novara is so much on a level with its general surface, that the eye catches the distant Apennines only at the more elevated points. The screen which here, and for miles after leaving Turin, shuts out the view of the Apennines, is the Colina. The Colina is a range of lovely hills, which rise to a height of rather more than 1200 feet, and run eastward along the plain a few miles south of the Milan road. Soft and rich in their covering, picturesque in their forms, and indented with numerous dells, they look like miniature Alps set down on the plain, nearly equidistant from the great white hills on the north and the purple peaks on the south. The sun was near his setting; and his level rays, passing through fields of vapour,--presages of storm,--and shorn of the fiery brilliancy which is wont at eve to set these hills on a blaze, fell softly upon the dome of the Superga, and lighted up the white villas which stud the mountain by hundreds and hundreds throughout its whole extent. Vividly relieved by the deep azure of the vineyards, and looking, from their distance, no bigger than single blocks, these villas reminded one of a shower of marble, freshly fallen, and glittering in pearly whiteness in the setting rays. The road, which to me had an almost sacred character, being the beginning of my journey to Rome, was a straight line,--straight as the arrow's flight,--between fields of rich meadow land, and rows of elms and poplars, which ran on and on, till, in the far distance, they appeared to converge to a point. It was a broad, macadamized, substantial highway, of about thirty feet in width, having a white line of curb-stones placed eight or ten paces apart; outside of which was an excellent pathway for foot passengers. On the left rose the Alps, calm and majestic, clothed in the purple shadows of evening.
