The lo-west monthly points reached average the same in Philadelphia and 

 Kanawha county ; the highest monthly temperatures average, for the year, the 

 same in Philadelphia and Greenbrier county, while the average of the lower 

 extremes is less in the latter locality. Kanawha county and Cincinnati show 

 very similar extremes, the former being slightly more moderate in high tem- 

 peratures, with a still greater depression in low tcmj)eratures, giving a pretty 

 wide thermometrical range, though the mean temperature is very nearly the 

 same as that of Cincinnati.^ As elsewhere in the interior or continental area, 

 or basin of the Mississippi, the extremes are greater than on the coast of lake 

 or ocean. Thus the table above, as might be expected, gives Philadelphia a 

 temperature less liable to extremes. 



The followang table includes a record of temperature, as furnished by authori- 

 ties and in periods as folloAvs : Lewisburg, two years, (Agricultural Report;) 

 Richmond, four years, (Darby's U. S.;) Washington, thirteen years, (Army 

 Meteorological Register;) Baltimore, four years, (record, "Fort McHenry ;) Phil- 

 adelphia, thirty-two years, (Daily Inquirer;) Cincinnati, twenty years, (Ray;) 

 St. Louis, twenty-eight years, (record, Jefferson Barracks.)

The mildness of the winter and spring temperature at Lewisburg is remarka- 

 ble, and must result in part, at least, from the prevalence of southerly and 

 southwesterly winds at that season. It will be seen that the summer tempera- 

 ture is lower than that of any other point named. The purity of the summer 

 air at this point modifies the efiects of the heat, and relieves it of sultriness and 

 the depressing influence of a vitiated atmosphere. 



The average of the five hottest days in five years, from 1832 to 1836 inclu- 

 sive, according to the record of J. H. Diss Debar, taken in Doddridge county, 

 very near the geographical and thermal centre of the State, is 90° Fahrenheit, 

 and the average of the coldest days, for the same period, 6° Fahrenheit. 



From the extremely broken character of the surface there are sheltered 

 localities upon which the summer sun must pour a merciless flood of fiery 

 beams, and high plateaus, or elevated slopes, over which the wintry wind must
