The cliffs are carved into many fantastic and bewildering shapes. Before we have got very far we are brought up short by an immense hole or funnel, cut clean-lipped from the short turf, and just the shape of one of those paper twists shop-keepers make for sweets. It is much larger in circumference than the Funnel at Tol Pedn. No railing protects the edge; people at the Lizard are supposed to have their wits about them. By lying down flat and approaching cautiously, we can peer over and see that here also the sea runs in on the floor. This is one of the cliff vagaries made within the memory of man. On the night of February 19, 1847, the hole appeared suddenly, yet so quietly that no one knew of it until it was seen. There had apparently been a shell or roof which had given way as the sea scooped out the earth from below. Yet that such a sudden catastrophe is possible shows how little we know about what goes on under our feet. A little further on a column of spray shoots in fluffy steam from a blow-hole every few seconds after the last billow has fallen away. Near it a huge boulder perched on a great plinth balances at an uncertain angle. How did it get there? At every turn "chairs" of stone extend a silent invitation to us to seat ourselves and gaze at the ships passing and repassing in a silent and endless procession. The Serpentine rock streaked with hornblende, felspar, slate and green-stone, shows changing colours like a pigeon's breast. It weathers into columns and pillars and arches and caverns, as if on purpose to delight the hearts of children of a larger growth, too old for spades and pails. Only a mile or two away at Kynance Cove these wonders come to perfection in the torn and twisted rocks lying in masses on the shore, which is covered with shining sand in summer but scoured black and stony by the rough seas in winter. By Caerthillian Cove we may pass to Pentreath beach and Yellow Carn and thus to Kynance. At places the cliffs have broken away forming a natural quarry and here come the people from the little town above, and search for well-coloured fragments of serpentine to fashion into candlesticks, and brooches, and ash-trays to sell to tourists. Dark red is a rare and popular colour and dark green also; chocolate with splashes of green, like variegated marble, is often seen. There is little fishing to be done on this wild rigid coast, and beyond some rough farming and their "serpentine" shops, it is hard to see what the population live upon. The rocks at the Lizard are split more often horizontally than vertically, and instead of being sharp upright columns as the granite fragments are at Land's End, these are broad lumps giving a curious sense of steady untiring watching with uplifted heads.
