ClimaioUxju. Those features of the meteorology which go to make 

 up the climate have been coiiii)ile(l and i)ul)lished by J. Warren Smith^ 

 in a report covering the state of ()hio as a whole and earlier as Section 

 71, South-central Ohio (IDIO) in the general summary of climatological 

 data for the United States. It is from the introductory matter of the 

 latter report, as more .si)ecifically describing conditions in our area 

 than the general bnlh'tiii, that tlie direct (|uotations given below were 

 taken. 



No recoi-ds have been taken within the area itself but the data 

 given for sumounding towns, since they are reasonably concordant, 

 give, it is believed, an accurate idea of the larger climatic features affect- 

 ing vegetation. "J'he stations selected are: Lancaster, about five miles 

 north of the area with a record twelve years in length, from 1896 to 

 1908; Logan, about 10 miles east of the area, with records for sixteen 

 years, from 1884 to 1900 ; ( 'ircleville, about 15 miles west of the area, 

 with records of twenty years, from 1888 to 1908 ; JMcArthur, about 

 twenty miles to the south, with records for the live years from 1894 

 to 1899, and parts of three additional years; whih' the observations 

 of the regular Weather Bureau station at Cohuubus, thirty-five miles 

 northwest, with records extending back to 1878, have In^en used for 

 comparison. 



The monthly mean temperatures in degrees Farenheit of those 

 stations whose records are available are as follows: 



The highest and lowest temperatures ever recorded are 102° and 

 ■21° at Cireleville, 99° and -21° at Lancaster, 104° and -20° at Colum- 

 bus. The highest temperature is usually reached in July, but August 

 is nearly as hot. The lowest temperatures are sometimes reached ii;
