MODERN METHODS OF STREET CLEANING 



stances producing a change in the condition of the 

 streets, they may shift from one undertaking to an- 

 other. Thus a workman may leave sweeping for 

 sanding, or, in case of snow, may set aside other duties 

 temporarily to put salt on the carriageways. 



The orderlies are generally provided with short- 

 handled brooms and scoops and either have hand-carts or 

 are in close proximity to places for the temporary storage 

 of the refuse which they remove from the pavements. 



The night work consists in watering the streets and 

 then either (a) sweeping them with horse brooms or 

 horse-propelled squeegees, or (6) flushing them with 

 a stream from a hose accompanied by work with hand 

 brooms or squeegees. The best results, but the slow- 

 est and most expensive, are obtained with hand hose 

 and squeegees. 



In every case the cleaning begins with a thorough 

 sprinkling of the streets in some cities this covers 

 the sidewalks. In Paris the preliminary wetting is 

 followed by sweeping with a rotary broom and in 

 many cases by squeegees propelled by horses. Rotary 

 brooms, and rotary or fixed rubber squeegees hauled 

 by horses are much used in nearly all cities. 



The throw of the brooms and squeegees is, in most 

 cases, pushed by hand brooms or squeegees into piles 

 and left for collecting carts to remove. 



In Paris, much street dirt is flushed into the sewers. 

 The sewers of Paris are unprovided with catch basins, 

 and when built were intended to be sufficiently capa- 

 cious to carry off all the refuse which might get into 

 them. In other cities much of the finely comminuted 

 street refuse goes to the sewers also, but some of it 

 is caught by catch basins.
