WATER MARGINS 159 



foot of the rising ground on the right is somewhat 

 harsh and unnatural. A great improvement could 

 easily be effected by a moderate amount of navvy's 

 work, if it were directed to running a sharp-pointed 

 bay into the rising ground on the right, and tipping 

 the earth taken out into the square corner on the near 

 right hand; saving the bed of rushy growth and 

 planting it back on the new edge and into the bay. 

 The exact position of the excavation would be chosen 

 by following any indication towards a hollow form in 

 the ground above, and by considering how its lines 

 would harmonise with the lines already existing. 

 The two sides of the bay would also be eased down 

 after the manner of those hollow places one some- 

 times sees by pond or lake in rising ground where 

 cattle or wild creatures come down to drink.
