 third of a mile away.

So very offensive as to alarm all water takers. 



It caused such a prejudice that the supply was rejected, although the pollution 

 was of short duration. 



Strong fishy odor and taste; also odor of "smartweed." Popular complaint 

 was dead fish in water mains. 



Odor and taste were fishy, popularly attributed to dead fish; but this is absurd, 

 as the odor is that of live fish. 



Odor pondy and fishy; bad water; publicly condemned. Board of health 

 interfered, yet analysis showed that water was not unhealthful. 



Very rank, water smelled bad, particularly when warmed. Tasted bad, but 

 not injurious to health. Looked better than tasted or smelled. 



Water became unfit for use, musty or cucumber taste and smell, odor very 

 strong in hot water; water l)ecame slimy, making it exceedingly hard to filter.

I am much interested to know that you are taking up an investigation of algpe 

 and organisms, and I very much hope you will favor me witli all circulars and 

 information which you may issue relating to the same. I have not attempted 

 to fill out the circular on the back of your letter, l3ut so many cases of trouble of 

 this kind have come to my attention that any Usting of them would be very 



difficult. 



I am devoutly thankful that science in this particular instance has got beyond 

 the pursuit of science for recreation's sake and is doing good and endeavoring 

 again directly to be of much use to mankind. I beUeve your work is the first 

 done in line of either cure or prevention from alga' conducted in a rational man- 

 ner, or so far as I know even attempted, and I have been connected with or well 

 informed on public water supplies and their management all my professional 



life of some thirty-five years. The worst case I know of is at the reservoir. 



A special commission is at this moment charged with the duty of advising 

 whetlier or not property worth some two million dollars is to be abandoned on 

 account of annual trouble from algse.
