report was published in the University Quarterly} A series 

 of analyses of the Kaw river at Lawrence has also been 

 made, and a report on the analyses of the water, made during 

 several months of the year 1903, will appear in the Division of 

 Hydrography, United States Geological Survey. During the 

 last year we have made some analyses of the waters of the 

 Neosho river system. There are quite a number of cities on 

 the upper waters of this stream that are dependent on small 

 creeks running into the Neosho for their supply. We refer 

 especially to Florence, Peabody, Marion, Council Grove, White 

 City, and Cottonwood Falls. Beginning with Emporia, the 

 following cities are dependent on the Neosho river directly for 

 their water, viz. : Burlington, lola, Chanute, Parsons, and 

 Oswego. Analyses of Burlington and lola water were made 

 some time ago. The source of the Parsons water is a small 

 stream and pond tributary to the Neosho. The following towns, 

 situated on or near the Neosho river, are not yet supplied by 

 public water- works : LeRoy, Neosho Falls, Yates Center, Hum- 

 boldt, Erie, and Chetopa. We have taken up especially the 

 water-supply of Chanute, Oswego, and Chetopa. 



THE NEOSHO RIVER SYSTEM. 



The city of Chanute is one of the largest of those that draw 

 their public water-supply from the Neosho river. On May 1 

 of this year one of us- visited this city for the purpose of getting 

 samples of the water for analysis. The water-works, which are 

 owned by the city, are about one and a half miles east of the 

 city, on the west bank of the river. Worthington pumps are 

 used to pump the water from the river to the settling-basins 

 during the night, and to force it into the city mains during the 

 day. Although the pump-house is well above the river bank, 

 the pumps are down nearly to the river level, so as to avoid 

 suction as much as possible. 



There are two settling-basins, which are said to have a ca- 

 pacity of 2,500,000 gallons each. These basins are lined with 

 cement, and are connected through a gallery filled with gravel 

 and sand. The material in the filter is, however, not often 

 changed. The basins are cleaned about once a year, or when-
