BAILEY AND BARTOW : CITY WATER-SUPPLIES. 239 



ever the mud has accumulated sufficiently. At the time the 

 sample was taken the water in the river was only slightly 

 above medium height, and was clearer than usual for that time 

 of the year, as it had not been rendered turbid by recent rains. 



The capacity of the pump is 1,000,000 gallons per day, but it 

 is not running up to its maximum. The river is usually much 

 higher in the latter part of May and in June, but gets to the 

 worst and lowest stage in August or September. At the latter 

 date it does not flow rapidly and is covered with a green scum, 

 indicating vegetable growth. When the water is at its flood 

 stage, the river carries a large amount of silt, dead animals, 

 trees and all sorts of floating rubbish. A stream runs into the 

 river some distance north of the city, which in high water is 

 liable to bring considerable contamination to the water, as there 

 are slaughter-houses upon its banks. 



During the flood stage of the Neosho, the water covers the 

 bottoms and is up around the pump-house, but it has not cov- 

 ered the basins for some years. The city water is not very ex- 

 tensively used for drinking purposes, as many of the people 

 still use wells and cisterns. There were some cases of typhoid 

 fever, but there are not sufficient data to tell whether they are in 

 families using city water or not. The city has a sewer system, 

 which it is rapidly extending. The outlet is into the river, at 

 a point below the w^ater-works. The pipes of the water com- 

 pany are also being extended rapidly into the outlying parts of 

 the city, to accommodate the increasing population. 



The analysis which is given below, from what has been said, 

 evidently represents the water when in a good condition, better 

 than the average. A sample was taken from the river opposite 

 the pumping station, from the second settling-basin, and from 

 the city mains in Doctor Lardner's office.
