I ON A PIECE OF CHALK 27 



and these great grinders crunch, in the dark woods 

 of which the forest-bed is now the only trace, it is 

 impossible not to feel that they are as good 

 evidence of the lapse of time as the annual rings 

 of the tree stumps. 



Thus there is a writing upon the wall of cliffs
