In tlie sunnner ot liH 1 a sanitary survey nf tlie Obio Kiver along tbe 

 Sdutbern l)( niubiry (it Indiana was made, 'i'be work was startefl at Cin- 

 cinnati and samples of tbe river water were analyzed from tbis point to 

 tbe montli of tbe Wabasb Kiver. Tliey were collected at every mile witb 

 tbe exception of a sbort distance, wliere circumstances made it necessary 

 to take tbem every two miles. A study of tbe water and sewer system in 

 each city or town of sutbcient size to have such imi>rovements, was made. 

 Analyses, chemical and bacterial, were made of all water supplies, espe- 

 cial attention being given to those using the river for their source of 

 supplJ^ Manufacturing plants were visited, and if they were emptying 

 waste into the river, the kind, together with an estimate of tbe amount, 

 was noted. 



In tbe sunnner of 1012, a survey of the Wabash River from Bluffton to 

 its mouth was made and similar data collected. On both surveys a house- 

 boat e(inipped tor the lalmratory work and living ([uarters was used. Tbe 

 first summer a one-room houseboat was prepared, and although it was used 

 tbrougbout tbe summei', it was found to be rather small for the work. 

 Last sunnner a two-room bduseboat was built, special jittention being ]iaid 

 to tbe design. 



Tbis boat was found to be so well suited to tbe purpose that a stei'u 

 p.addle and an engine were installed, and it is to be used on White Kiver 

 next sunnner. 



Altbongb no innnediate results were looked for, yet an agitation was 

 started in lliree pl.-ices on tbe Ohio Ki\(M' nsulting in a tri'att-d water 

 supply tor one city and a change from tlie i-ivcr to a well suiijily in two
