The valley of the Pesio is about twelve miles long, and runs 
downwards to the north. It rises in limestone mountains of con- 
siderable height, the culminating point being Monte Marguareis, 
8800 feet in altitude. The view from many summits of the 
Piedmont plain, backed by the alpine chain from Monte Viso to 
Monte Rosa, is grand in the extreme. Many lateral valleys join 
the main valley throughout its entire length, each with its torrent. 
The lower valley is very park-like, and this characteristic continues 
as far up as Certosa, the meadows bordering the river being 
shaded by fine old chestnuts, and quantities of poplars, willows, 
walnuts, and fruit trees, whilst the slopes are covered with 
chestnut forests. Higher up beech and pines take the place of 
the chestnuts; and there is a rich sprinkling of ash, wych-elms
