The question of the exclusion of light, rather than 

 any insurmountable engineering problem, seems likely 

 to limit the height of buildings in America, in the near 

 future, as it does already in many European cities. 

 Groups of tall buildings on narrow streets put the 

 pavement in a constant state of gloom even on bright 

 days. It is probable, therefore, that the height of 

 the building on a street will be limited by the street's 

 width, or the distance from the street at which the 

 highest stories rise.
