6.^ There is a mound loeatecl on tlie Pence farm, on Flatroek River, Flat- 

 rock townsliip. two miles northeast of Clifford; explored by Dr. 

 Arwine in 1898. Bones, ashes and arrow-points were found. 



7. There is a mound one and one-half miles east of the last mentioned 



(No. 6) on James Hagar's farm. Never explored.

Microscopical ()R(;a.\is.ms Found in the LaFayette (Ind.) 



Reservoir. 



Severance Burrage. 



The reservoir of the city of LaFayette is located in a park on Oak- 

 land Hill, the highest point of land east of the city, with an altitude of 

 about two hundred feet above the level of the Wabash River. The reser- 

 voir itself is built up above the surrouhding land level, and the survey 

 head of the reservoir is given as two hundred and thirty-two feet. The 

 reservoir is not quite two hundred feet square, has a depth of twenty- 

 eight feet, and a capacity of four million two hundred thousand gallons. 

 The water with which this reservoir is supplied is obtained from the 

 regular city supply wells, wnich are driven forty or more feet into the 

 bed of the Wabash River. The water from these wells is remarl^ably 

 pure and free from organisms. A recent bacteriological analysis showed 

 but one germ to a cubic centimeter, and a microscopical examination was 

 a complete blank. Of course, this remarkable purity is at once lost when 

 this water is pumped up to the reservoir and exposed to the air and sun- 

 light. 



It is the purpose of this paper to give a census of the micro-organisms, 

 exclusive of the bactei*ia, found in this reservoir water, the figures being 

 obtained from twenty microscopical analyses, covering a period of five 

 years:
