THE BLUE-RIDGE, WARM-SPRING, &c. 221 



Notes. 



a. From the foot of the Blue-Ridge to the Gap is cat- 

 led two miles . From the Gap to the foot on the weftex'n 

 fide it is called one mile. 



b. During eleven days refidence at Staunton and in 33 

 obfervations, the mercury in the barometer did not rife 

 above 29.10, nor fall below 28.70. The thermometer 

 varied from 55 to 82, and the weather was fometimes 

 very clear and dry, and fometimes very cloudy with hard 

 rain. 



c. Thefe are called Warm-Spring Mountains, the 

 Warm Springs being near the foot at the weftern fide. 



d. This is not the top of the Ridge ; I could not go 

 up at this time, and when I returned 1 had not my baro- 

 meter : By ocular obfervation it appeared to me nearly, 

 if not quite, as high above the road on the firft mountain 

 as the top of the Blue Ridge above the Gap. 



e. During 29 days refidence at the Red Springs, the 

 mercury in the barometer varied only o. 1 9 ; the thermo- 

 meter varied 3 1 degrees and the weather was at the two 

 eKtremes of wet and dry.
