It is probable that the constituents are combined as follows: 



Silica and insoluble residue. . . 1.43 Magnesium carbonate 5.G2 



Iron and alumina oxids 0.56 Sodium cblorid 5.()9 



Calcium carbonate 30.05 Sodium sulfate 5. 08 



Calcium sulfate 0.12 



SANITARY ANALYSIS, PARTIAL. 



Total solids 49.9200 Nitrates and nitrites 0.0120 



Free ammonia O.OOOfi Chlorin 3.4500 



Albuminoid ammonia 0.0300 



An analysis of the Stranger, made by Mr. J. G. Hall in May, 1894, 

 showed that 100,000 parts contained 27.00 total solids, consisting 

 essentially of calcium sulfate and calcium carbonate. The amount 

 of sodium chlorid was small, T.21 parts. As this stream is quite 

 small its waters do not contribute very materially to the waters of the 

 Kaw as delivered at its mouth; in fact it is but little larger than 

 several other creeks that flow into the river both from the north and 

 the south sides. 



These constituents may best be compared by the graphic method. 

 From this it can be seen at a glance what is the source of the import- 

 ant mineral constituents of the Kaw river.
