 of these come forward to the actual edge of the scarp, 

 and as there is no stone quite near the surface, the 

 gradual crumbling away of the sandy earth where they 

 first took root, threatens to leave the trees without 

 support. Now the Beech is evidently a tree with a 

 strong instinct of self-preservation and no small degree
