original idea of keeping footing in Piedmont, or
whether they thought twice before they exposed
considerable force TO possible retreat through dan

bridge over the Tcino at this point, constructed on
arches of solid blocks OF granite strong enough for

originally constructed. When The Austrians retired

about three kilometers about two miles and small

causeway in most parts from 20 TO 30 feet above the
welrrigated fields, which evidently once formed the

been constructed with view TO fertilize these low
