fea-fhore ; and at the end of forty hours an 

 excellent lime is produced. One-third of 

 this and two-thirds of puzzolana, mixed 

 together with water, form a cement which 

 unites and hinds the pieces of lava here 

 ufed inftead of bricks and ftonts ; and to 

 give, as they affirm, a greater flrength and 

 folidity to the cement, they mix with it 

 pounded pumice of their own country. 



Lavas are ufed as mateiials for the build- 

 ing of houfes, not only by the inhabitants; 

 of Felicuda, but by thofe of all the other 

 Eolian iiles, each ufing thofe of their own 

 ifland ; and it is the pradice, not only in 

 the country but even in cities, to build with 

 fuch flones as the environs afford, efpecially 

 when they are mountainous. I therefore, 

 wherever I went, conftantly examined the 

 materials of which the villages, towns, and 

 cities through which I paffed were built ; 

 which frequently afforded me a light and 

 diredlion in my enquiries relative to the fqi^ 

 fil fubftances of thofe countries.
