 water, see c. 



"Where the water flowing swiftly into a basin 

 forms an island at the inlet, it will take about the 

 shape of d; following the outer banks, the swiftly 

 flowing stream by its strong pressure on both sides 

 will somewhat round the ends. But if the river 

 widens into a lake by gently filling a deep basin, 

 rather than rushing into it, then e may be assumed 

 as the natural shape, for here the river doesn't round 

 off both sides, but forms in a slow current on the 

 right, a long spit on the left bank, beyond which 

 the quiet water, no longer in a powerful stream, pro- 

 ceeds and gently flows round the higher ground. 

 Very seldom, on the other hand, does a stream flow 

 into such a basin as is generally made out, after the 

 model of a bottle, see /. 



"Let the surface and shelving of an island on the 

 same principle be constructed in accordance with 

 the probable effect of the terrain and the water which 

 washes it. The equal shelving on all sides and the 

 equality of height throughout is the commonest 

 mistake. I fell into this error at first ; g is bad and 

 b is good. 



"But even the best forms may be bettered by 

 plantations skilfully arranged covering the spots 

 that appear less satisfactory and giving more variety 

 to the surface without disturbing the harmony, con- 

 cerning which the right feeling certainly must again 

 decide; united taste and experience, recognizing the
