OPERATION AND MAINTENANCE. 



It has long been recognized that in the construction of drainage 

 improvements the services of men who make the planning and the 

 supervision of such work a specialty is a business necessity. State 

 drainage laws require that such men be employed on districts organ- 

 ized under the law. It is to be regretted that such laws do not also 

 provide for engineering supervision of the operation of the pumping 

 plant and in the maintenance of all the drainage improvements. 

 The successful and economical operation of the pumping plant and 

 the proper maintenance of the plant and the other drainage improve- 

 ments require the careful and constant attention of those who are 

 especially fitted by training and experience to do such work. On 

 many districts examined the operating expenses of the pumping 

 plant were unnecessarily large, the drainage improvements were 

 rapidly deteriorating, and large damage had occurred from the 

 partial or complete failure of some of the improvements. Such 

 districts did not have proper supervision. 



The presenl system of having a number of commissioners responsi- 

 ble for the administration of the affairs of the districts is wrong. 

 Much is lost, by this division of authority, and responsibility for any 

 feature of the administration is hard to (ix. Someone should be 

 hind by the districl to have full charge of the administration of the 

 district business, and ho should he made entirely responsible for the 

 -me,-- of -i| ( |, administration. As an example of the divided 

 authority, 'he records of one of the districts on the Illinois River 

 showed thai in the building of a house for the storage of coal at the
