136 NATURE NEAR LONDON. 



V, stretch apart and glitter, and every dip of the oars 

 and the sHppery oar blades themselves, as they rise 

 out of the water, reflect the sunshine. The boat 

 appears but to touch the surface, instead of sinking 

 into it, for the water is transparent, and the eye can 

 see underneath the keel. 



Here, by some decaying piles, a deep eddy whirls

 from you, dark shadowy spots fluctuate to and fro in

 from below^ a ceaseless succession of irregular circles 

 as if the water there expanded from a centre, marking 

 the verge of its outflow with bubbles and raised lines
