MODERN METHODS OF STREET CLEANING 



Waring which showed that the refuse could be over- 

 hauled and the marketable ingredients separated and 

 sold advantageously by the city, but the results of these 

 experiments have not led to any important changes in 

 the plant or methods of disposition followed by the city. 



In the borough of Brooklyn a private corporation has 

 a contract for the final disposition of ashes, street 

 sweepings, and rubbish. This company has thirteen 

 receiving stations located at various points in the 

 borough. The carts of the Street Cleaning Depart- 

 ment deliver their loads at these receiving depots, 

 and, after the marketable portions have been sorted 

 out, the refuse is conveyed in iron receptacles on electric 

 trolley cars to low-lying land where the material is 

 tipped. Refuse destructors have been constructed at 

 two of these stations. 



That portion of the refuse which consists of paper 

 and other inflammable matter has been experimented 

 with by the city to determine the conditions under 

 which it can be burned in destructors. These experi- 

 ments indicate that about 2.2 pounds of water can be 

 evaporated at 212 F. per pound of rubbish. The city 

 has several small destructors, but this system has not 

 as yet been extensively employed for disposing of any 

 part of the city's wastes. In fact, the care which these 

 plants receive discourages the belief that first class 

 destructor works would be successful. 



Before 1896 snow was removed by the department

streets by contracts drawn up and let, after 

 public bidding, by the Street Cleaning Department. 

 The regular force is quite incapable of dealing with this
