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 
pressure in the large main from which we were taking the water.

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