MODERN METHODS OF STREET CLEANING 



stables them in buildings which the city owns or rents. 

 The number of horses used by the city in cleaning the 

 streets in 1907 was 2064. The average cost of keeping 

 these horses was $490 per horse per year. This is some- 

 what in excess of the cost to private corporations of 

 keeping horses in New York City. Self-propelled vehi- 

 cles have not so far been employed. 



Refuse other than garbage is transported by water by 

 means of barges or scows. These scows are of three 

 Disposition principal kinds. There is a flat scow which 

 otifer'than i g unloaded by hand when used for dumping 

 Garbage refuse at sea and by a mechanical orange-peel 

 bucket when used for filling in low-lying land. A 



v O 



mechanical dumping scow, known as the "Barney," 

 consists of two sections of a boat so built and placed 

 as to make practically one craft. The load is carried 

 between the two sections. When the load is to be 

 discharged the two sections are separated by means of 

 a mechanical arrangement and the contents fall out. 

 The Barney dumper is used only for transporting refuse 

 to sea. The third type of scow is a self-dumping, self- 

 propelling catamaran called the "Delehanty." The 

 refuse is carried in pockets suspended between the 

 two hulls. The city owns 42 deck scows and 3 Dele- 

 hanty catamarans. 



The principal plant and apparatus owned by the 

 Street Cleaning Department include, beside the stables, 

 dumps, and scows, 1120 garbage and ash carts, 254 

 paper carts, 87 water carts, 63 sweeping machines, and 

 2064 horses. 



The following table will give an idea of the money 

 cost spent each year by the Street Cleaning Depart- 



ment for various purposes:
