EXPERIMENT STATION REPORTS. 209 



water is used for long periods. Such conditions are unnecessary and 

 further, are very dangerous. 



The results obtained from the examination of the College swimming 

 pool show very conclusively that a swimming pool must be checked 

 constantly by bacteriological procedure. The College pool has been 

 examined daily during the school year. I wish to again repeat that 

 the svstem of chlorination is verv unsatisfactory and should be replaced 

 preferably by liquid chlorination. 



Two disinfectants were submitted for examination. Both of them 

 failed to show anv germicidal value even when full strength was used.

I wish to thank you in behalf of myself and all the members of the 

 Bacteriological Section Staff for your invariable courtesy and helpful 

 spirit in all our mutual undertakings. 



Respectfullv.
