iv PREFACE 



been found most certain in application and useful in results 

 are shown in these chapters. 



In the development of the subject, the various reports of 

 the Committee of the New England Water Works Association 

 on Meter Rates, which were drawn by the author as Chairman 

 of the Committee, are taken as a starting point. Additional 

 explanatory and statistical matter is added, many kindred 

 subjects are investigated and practical methods of application 

 that have been tested by experience are added. 



Diagrams are used to show the meter rates now in force in 

 many American cities. These are drawn to permit ready com- 

 parison. Free use has been made of the Committee's reports 

 and data and also of the writings of others, especially of those 

 who were and are personal friends of the author, and who 

 are also solid, substantial water works men who have contributed 

 to the development of the meter business, and who have helped 

 to establish the principles of fair rates. 



If some of these quotations are old, it does not follow that 

 the business is not developing. It rather indicates that some 

 of the underlying principles do not change and that they were 

 recognized by practical water works men long ago.
