Another effect of water is seen in the superficial deposit of water-rounded boulders (Fig. 256), whIch the artist however has strewn rather too freely in unlikely positions. In Fig. 257 we have a plarlorm of marine denudation with a wave-cut arch; following this level to the right the eye detects further relics of the same platform. The manner of representing the crags on the right at the top is a conventional one,seen in many such pictures, an.d perhaps related to cal... (查看原文)
