an Eruption of Mount Vefuvius. 7 3 
were {hewn three grottoes, from which iffues a conftant 
extreme cold wind, and at times with impetuofity, and a 
noife like water dafhing upon rocks. They are fhvtt up 
with doors like cellars, and are made ufe of as fuch, as 
alfo to keep proviiions freih and to cool liquors. I had 
never feen thefe ventaroli before. In my letter to Dr. 
maty, upon the nature of the foil round Naples, I have 
mentioned others of the fame kind that I had met with 
on Vefuvius, Etna, and in the I {land of Ifchia'A 
We obferved, that the trail of country completely co- 
vered with a Jlratum of the volcanic matter above men- 
tioned was about two miles and a half broad, and as 
much in length, in which fpace the vines and fruit trees 
were totally {tripped of their leaves and fruit, and had 
the appearance of being quite burnt up; but, to my 
great furprize, having vilited that country again two 
days ago, I faw thofe very trees, which were apple, pear, 
peach, and apricot, in blolfom again, and fome with the 
fruit already formed, and of the lize of hazel-nuts. The 
vines there had alfo put forth frefh leaves, and were in

r oentaroli\ and the inhabitants of that town, by means of leaden pipes, conduct 
the frefh air from them into the very rooms of their houfes, fo that by turning a 
cock they can cool them to any degree. Some who have refined flill more upon 
this luxury, by fmaller pipes, bring this cold air under the dining table, fo as to 
cool the bottle of liquor upon it.
