 line and permit a tower or belfry or other such feature to be carried up 

 on the street line, a feature which would hardly be possible under Section 

 9, paragraph (d), except on a street over 100 feet wide. On a 100-foot 

 frontage this dormer provision will mean that the dormer on the street 

 line at the height limit can be 60 feet wide ; by the time it has gone up 10 

 feet it can be only 50 feet wide ; by the time it has gone up 30 feet it can 

 be only 30 feet wide, and by the time it has gone up 60 feet it will be 

 reduced to a point. This rule will create at least three limiting planes which 

 intersect the setback plane, as shown on the accompanying diagram.

Sec. 9, Par. (d). If a street, park or open space is 150 feet or more 

 Tu clear width in front of a building, a tower may be built directly across 

 the whole front of the building provided the tower does not cover more 

 than 25 per cent of the area of the lot. On a street 100 feet wide a tower 

 can be built across the whole front of the building provided that it sets back 

 25 feet from the street line and also that it does not occupy more than 25 

 per cent of the area of the lot. If the building has 200 feet frontage on 

 a 100-foot street, a tower with a 50-foot frontage may be built on the 

 street line to any height and then splay back on either side in a ratio of
