 On the 16th it snowed as hard as ever I knew. Cleared up at

 month. Wind easterly till the 14th, afterwards mostly westward. 



Extremely dry : seldom any clouds ; no rain. Every vegetable 

 almost" burnt up ; strawberry leaves, green plantain and others 

 so crisp as to crumble. In this month many cattle died for want 

 of food. 



Seasonable weather. 



Very dry. 



Very dry. 



Very dry. 



Seasonable weather toward the end of the month. This was the 

 driest summer and autumn ever remembered. Many springs dried 

 up that ran brisk before. My spring, a remarkably good one, 

 ran verv low and the water was unpleasant. 



On the i8th I felt three shocks of an earthquake about eight 

 minutes before 4 o'clock in the moi-ning. The first was severest. 

 It shook the house very much and waked me. The second was 

 less, and the third least of all. They succeeded each other at 

 about the one minute distance, and were felt all over the 

 continent 



On the 16th there was a brisk southerlv wind. The mercury about 

 noon at 71°, at 4 P.M.. at 69°. At 5 P. M. o'clock the wind came 

 from the northwest, hlew excessively hard, and did great damage 

 in the counfy. A prodigious quantity of rain fell. It cleared 

 up at 6 o'clock, but the wind continued blowing hard all night. 

 At S o'clock the mercury was at 43°, at 7 o'clock next morning 

 at 26°, at 9 o'clock at 24.5°, and following morning, viz.,the 18th, 

 the mercury Avas at 15°. 



No record, being hindered by business. 



Seasonable weather. 



Seasonable weather. 



Plenty of rain. Tlie season much colder than usual. Mercury 

 standing frequently between 60° and 70°. On the 22d, in the 

 morning, a black cloud came from the northward, soon overspread 

 the hemisphei'e and threatened much wind and rain, hut soon 

 blew over without much wind or rain. The sun shone clear, and 

 the weather calm, till toward noon, when clouds collected toward 

 the north and northwest. About 3 P. M. there was the most 

 threatening- appearance I ever b<^held, the clouds in some places 

 of a deep green, in others of a sooty hlack. At 45 minutes past 



3 it began to rain and blow, attended with remarkably severe 

 thunden but as the thunder stopped the clock I cannot say how 

 long it lasted, but suppose near half an hour, in which time the 

 most rain fell I ever saw. The wind did incredible damage 'n 

 s<^veral parts of the country. In St. Mary's county, it is said, 

 200 houses were blowTi down and many people killed. In every 

 county in Maryland much damage was" done by this gust, whicu 

 was the most "general ever remembered. It was all over New 

 York, the Jerseys, Pennsylvania. Maryland and Virginia, and 

 did much damage everywhere. How much further it extended, 

 eitber northward or southward, I have not heard.
