On the pass Valparola, the contrary dip of the beds is just as 

 clearly seen, though the erosion has only jiroceeded down to the St. 

 Cassian Beds. For the last hour or so of the ascent to this Pass one 

 walks over the debris of these beds, and meets with plenty of 

 detached blocks of the strata to impress one with their highly fossil- 

 iferous and often oolitic character. Looking down from the Pass 

 into the valley beneath, with the village of St. Cassian lying below, 

 the structure of the valley can be clearly seen as the eye traces the 

 strike of the several series of strata in the side of the mountain. 

 Subjoined is a section of one side of the Yalley of St. Cassian.
