meter to its various consumers. According to Mr. J. H. 

 Fuertes,* the company is never able to account for more 

 than 80 per cent of the water, although by rigid inspections 

 and immediate stoppage of all leaks they are able to keep 

 close to this limit. If a small supply, distributed through only 

 about 30 miles of street mains, with every inducement for 

 both water company and consumer to keep down the leaks, 

 is subject to such a loss, it may be regarded as ideal when 

 80 per cent of the water-consumption is accounted for. The 

 following table from Mr. Fuertes' reportf gives other data, 

 showing how, from the best evidence possible, the amount not 

 accounted for varies from 16 to 43 per cent.
