There are perhaps three horizons, or beds, in which these substances 

 might be expected to occur. The uppermost of these has been removed 

 from the region under consideration, and is the upper Elmdale gas-bear- 

 ing bed. The next is the one from which the gas occtirs at Elmdale, re- 

 ported to me to be 700 feet below the first. This would be some 600 to 

 6-50 feet below the river level. Another mighr occur at 1.000 or 1.200 

 feet below the surface. It is also possible that the basal Cherokee shales 

 niighc prove productive, but this is very doubtful. The Cherokee shales 

 are productive in eastern Kansas and Oklahoma. 



I believe this field is worth a thorough test for the existence of these 

 materials. It is too large for one or two wells to test it out thoroughly, 

 unless by accident the first ones happen to hit the most favorable places. 



Algae of Kansas Reservoirs.^ 



ixTRODrcnox. 



This report has been prepared with a two-fold purpose. First, it is 

 intended to serve as an aid to the sanitary engineer by explaining the 

 harmful effects of heavy growths of microorganisms in the city water 

 reservoirs, and by describing the organisms causing trouble and the 

 best methods for their eradication. Second, it is the first report of the 

 survey of the algse of Kansas by the University. 



This survey was planned several years ago by Prof. W. C. Stevens and 

 Dr. Grace M. Charles of the Department of Botany and Prof. C. C. • 

 Young and Miss Myrtle Greenfield of the Water and Sewage Laboratory 

 of the State Board of Health. As a part of this plan, adapted es- 

 pecially to the need of the sanitary engineer, I began in 1915 to study 

 the algse of the surface water reservoirs of the cities of Kansas. 

 Through the generosity of Mr. Young, I was provided with reference 

 works and the standard conveniences for collecting the samples over the 

 state, and for making the analyses. 



In elassif3ring the 110 species of algae listed in this report, the follow- 

 ing books were found most valuable. '"Sylloge Algarum," by De Tcni; 

 •'Minnesota Algae. Vol. I." by Miss Tilden; Wolle's "Fresh-Water Algae 

 of the United States"; "The Green Algs of North America," by Stokes; 

 "The Algse of the Fresh Waters of Connecticut," by Conn; "Synopsis 

 des Diatcmees de Belgique." by Van Heurick; and "Die Naturlichen 

 Pflanzenfamilien,'' by Engler and Prantl. 



The key adopted in this bulletin is based upon that given by Miss 

 Tilden for the Myxophyceas, F. S. CoUins for the Heterokontae and 

 ChlorophycesB, with the exception of the family Desmidiaces. where 

 Stokes' classification is used. Shut was the authority for the Bacillarieae. 



(I take this opportunity of expressing my appreciation for advice 

 and suggestions throughout the progress of the work to Miss Charles 

 and Miss Greenfield.)
