 falls that occurred last winter. 



Of special importance may be mentioned the connecting of 

 our two largest water-mains with the high pressure main on 

 Southern Boulevard. This was demanded by a change made by 

 the Water Department, which at once produced extremely low

 kept in a very orderly and clean condition. The summons system
