304 PHILOSOPHICAL TRANSACTIONS. [aNNO 1753, 



as at a great distance, from the same point. About 5 the sky was a little over- 

 cast with clouds, but the air continued in a dead calm. Suddenly a violent 

 rushing noise was heard; the sky seemed to open, and emitted a flash of light- 

 ning ; but no noise of thunder ; and a stream of wind instantly ensued, the vio- 

 lence of which nothing could resist. 



This stream of wind, so far as can be traced by its effects, arose from a glin 

 called AUgolan, and continued its course for 3 miles from s. e. to n. w. The 

 violent current of it seemed to be confined to a space about l6 feet in breadth, 

 and the whole body of the air in motion did not exceed 6o feet, as may be com- 

 puted from some of the particulars which happened in the little village of Lisna- 

 cloon in the parish of Termonomungan, and the edge of the parish of Urney. 

 At the distance of a mile to the s. e. of this village, it cut a line through several 

 clamps of turf, which were standing in a bog, and threw down all the clamps in 

 this line. Thence it crossed the river Derge, in the same line, and dashed up 

 the water with great noise and violence. Thence, in the same line, and at the 

 space of half a mile, it took the village of Lisnacloon, carrying away fences, 

 the roofs of houses, and the tops of stacks. It then burst with incredible vio- 

 lence through a cow-house, and cut a passage of l6 feet quite through it, and 

 carried some of the ribs of the house before it 400 yards into the field; the rest 

 of the house was a little ruffled. A woman who was gone into the cow-house 

 a minute before, was knocked down by one of the ribs falling. She declared 

 that it was a dead calm the minute before; when, on a sudden, she saw a flash 

 of lightning, and heard and felt the violent storm, but heard no thunder. A 

 man being in the same field, but out of the line, in which the stream of wind 

 passed, felt no wind, but heard a mighty rushing noise, and saw the timber, 

 thatch, turf, and dust of the houses, fly by him, at the distance of 40 yards. 

 He saw a flight of rooks dashed down in the same field. In this village are se- 

 veral other inhabited houses, both on the north and south sides of the course of 

 this stream, none of which were in the least ruflied. The air continued still 

 among these houses ; and the inhabitants stood astonished, on seeing the sudden 

 devastation so near them. 



After passing this village, the stream was continued in the same line, but with 

 less violence, to a large hill in the parish of Urney, called Muckle, and on the 

 north side of the hill, at the distance of a mile from Lisnacloon, burst open the 

 door of a weaver, and broke down a web in his loom. As at this last place 

 it entered a large bog, which is extended for 3 miles, it could be traced no 

 farther. 



The time, in which this stream passed through the village of Lisnacloon, was 

 about 5 minutes. It was succeeded immediately by a torrent of rain.
