of the latter. This is the case where buildings 

 intervene. On the other hand, where the street 

 spaces join that of the river, they add materially 

 to its value in the landscape. 



The arrangement recommended need not interfere 

 with using the river as a source of power, since the 

 power can easily be carried on a \vire to any suitable 

 place for a factory. The construction of dams, 

 while interfering with the effect of running water, 

 may sometimes substitute for this the reflections of 

 still water and a desirable place for boating. \\hen 

 a dam is placed above a city and the water of the 

 river is carried in a canal to some lower point for the 

 development of power, the normal flow of water 

 through the river channel below the dam is, of course,
