pavement ready to be cleaned with water from a hose 

 or by other means. Hand-sweeping is best to pick 

 up of coarse litter and horse droppings soon after 

 they appear upon the pavements. 



One of the most efficient ways used in Europe for 

 cleaning smooth pavements, such as asphalt, is by means 

 of sprinkled water speedily followed by scrap- ciwi 

 ing with rubber squeegees. In this case the with Rubber 

 dirt is first lubricated, then scraped away and 

 the pavements partially dried by the scraping. Machine- 

 scrapers hauled by horses are widely employed in Europe 

 to clean asphalt streets. There is no difficulty in carry- 

 ing this dirt through the sewers because the streets are 

 not allowed to become so heavily coated with refuse 

 before being cleaned that the quantity of dirt which 

 enters the sewers is large. Where the amount of dirt 

 on the pavement is great, most of it should first be 

 removed by brooms before the more thorough cleansing 

 with water begins. 



Sprinkling is not necessary on thoroughly well cleaned 

 pavements and in some cities it is not done. Sprinkling 

 does not cool the air appreciably, as is popu- 

 larly supposed, nor does it clean the streets. 

 The water runs to the sides of asphalt streets and there 

 forms pools which sometimes become offensive in hot 

 weather. Where the streets are continually used by 

 pedestrians, sprinkling causes annoyance while the pave- 

 ment is wet. As most streets are not thoroughly cleaned, 

 sprinkling is a favorite way to lay the dust. 



Macadam roads are among those which can be 

 sprinkled to good advantage. Sprinkling with oil is 

 losing favor in Europe, the benefit not being commen- 

 surate with the cost and inconveniences entailed. On
