We rode in this smoke all the way to Elmira; and it did 
not leave there until about 8 P. M., when the wind veered to 
about N. N. W. and soon cleared it entirely away. 
I made such inquiries as I could during my short stay ; 
and learned the following additional facts. ’ 
A gentleman in the train preceding me, met the smoke 
about 40 miles west of Binghamton at 34 P. M. or about one 
hour previous to its reaching Binghamton. At Elmira it 
made its appearance about 3 P. M. with a cool, strong, 
westerly wind. 
There were no fires (as far as I could learn) in the woods 
of the vicinity ; and yet the smoke was more dense than I 
have ever seen it, with the woods burning in plain sight of 
the valley. 
The wind at Elmira was southerly in the morning; and 
thermometer at 75° to 80°. 
The barometer was as follows: 
9 A. M. 28°74 inches. 6 P. M. 28°84. 9 P.-M. 29 in. 
The thermometer at 9 P. M. 55°. These figures are not 
exact, as the instruments were not first class; and observa- 
tions were roughly made. The fact is certain, however, that 
the smoke was traveling eastward at the rapid rate of nearly 
40 miles per hour; that it was preceded bya high thermome- 
ter and low barometer; that at the time of its appearance there 
was a rapid change of wind, with a great increase of force; 
and that as it disappeared the barometer rose, the thermome- 
ter fell; and the wind changing still farther, gradually died 
out. 
Now this area of low barometer occupied nearly the 
entire day (morning till night) in passing over Elmira, and 
was no doubt central near there about the time of the smoke 
appearing. 
By the “ weather report” of that kai (Friday at 1 A. M.) 
IT learn as follows: 
“The low barometer which was Wednesday. night over 
Wisconsin moved rapidly eastward, and is now central north 
of Lake Erie, extending probably over a large region. Hx-
