[From tne Cincinnati Grzette of yesterda} r .] 
Un the fever prevailing about Springfield. 
Cincinnati Reading-Room , Sept. 27, 1819. 
I learn mat an U uusual degree of sick¬ 
ness prevails now. through the country 
between this and Hamilton, about Spring- 
field and the head branches of Millcreek, 
although most other parts of this country 
is remarkably healthy this year, particu¬ 
larly the town, and along the neighbor¬ 
hood of the river. 
Some suppose this sickness to have ori¬ 
ginated from the big pond 4 or 5 miles 
this side of Hamilton; but as the sick-, 
ness now rages '8 or 10 miles south of the 
pond, in a district where there is no stag¬ 
nant water, I am led to believe, from the 
inquiries I have made, that it is more ow¬ 
ing to the unusual dryness of the season, 
and consequent scarcity of water to sa- 
j turate the air with moisture sufficient to 
; prevent it from being too great a non-con - 
| ductor, than to any redundancy of stag¬ 
nant water. The streams of water are 
i very low, and many oi them quite dry, 
I as might be expected in a country where 
the hills are so little elevated. The cause 
is therefore rather to be sought for in the 
i water used for culinary uses and drink¬ 
ing, than in the air.
