 quarter of a yard, and afterwards closed again so 

 exactly that scarcely any mark of the injury was left. 

 At Colares, about 20 miles from Lisbon, and two 

 miles from the sea, on the last day of October, the 

 weather was clear, and uncommonly warm for the 

 season. About four o'clock in the afternoon there 

 arose a fog, which came from the sea, and covered

 felt, which was quickly succeeded by a second and 

 third; and at the same time several light flames of 

 jfire issued from the mountains resembling the kind-

 the buildings moved from east to west. In another 

 situation, from whence the sea coast could he dis-

 the Fojo a great quantity of smoke, very thick, but 

 not very black. This still increased with the 

 fourth shock, and afterwards continued to issue in 

 a greater or less degree. Just as the subterraneous 

 rumblings were heard, the smoke was always ob-
