MODERN METHODS OF STREET CLEANING 



about 2 P.M. at certain times, that is, on principal 

 market days, as many as sixteen wagons are required 

 for this work. 



The cleaning of the sewer catch basins, of which there 

 are about 7000, is accomplished by special gangs, one 

 in each cleaning district. The mud wagons used in 

 removing this refuse are of iron and of 1.9 cubic yards 

 capacity. The cost of cleaning each basin is reckoned 

 at $1.66 for the year. Of this $.95 are charged to the 

 Board of Works and $.71 to the department of street 

 cleaning. 



The cab stands and numerous narrow alleys are 

 washed regularly once, and sometimes twice, a week, 

 in summer. 



The streets are sprinkled in the day from April 1 

 until October 1. All the principal streets are sprinkled, 

 including those of the suburbs, by sprinkling- 

 wagons. The carriageways and sidewalks of 

 other streets are sprinkled by means of hose carried 

 from place to place on reels or drum carts. Three 

 different kinds of sprinkling- wagons are used: 



1. Wagons with turbine pumps for the broad streets 

 of the new city. These wet a path 11 yards wide. 



2. Miller's patent wagon for the wider streets of the 

 old city. These have a capacity for wetting a path 

 8 yards wide. 



3. Wagons with rose sprinklers for the narrower 

 streets. These have a capacity for sprinkling a path 

 6 yards wide. 



The area sprinkled daily, including night sprinkling, 

 amounted to 2,393,403 square yards in 1907. 



For the removal of snow, the eight cleaning districts 

 are each divided into eight subdistricts. Each of these
