The Commission has on file atlases of all the boroughs except Rich- 

 mond, which show in detail on a scale of 50 or 60 feet to an inch, the 

 use, height, and approximate dimensions of all buildings as well as many 

 other details concerning them. These atlases are kept up to date by- 

 frequent revision and were constantly referred to in preparing the dis- 

 tricting maps. Only the data given in the atlases of greatest value in 

 districting is shown above.
