ON EXTINCT VOLCAN©!^. } 37 



To my great fatisfa^lion, after having traverfed pumice A quarry of 



(tones and volcanic fcoria?, I arrived at the foot of a quarry j^^^y^ "JJ^^^ j[^^ 



of lava, fr®m which hewn flones for building and millftones miliftoncs were 



were taken. This quarry was wrought in the open air, ^^^, Wroueht in th- 



was covered with a bed of mould about eighteen feet deep, open air, and

me from tracing the courfe of the lava, particularly as above Above it fcatter- 



this lava, nothing is to be found but fcattered blocks and fragments ^of 



fragments of lava, fcoriae, and pumice flones. I went to lava, fcoria, and 



the top of the mountain, however, in hopes of difcovering P""^'^^ **o"e. 



where the center might have been ; for the mountain of Agemberg not 



Agemberg, all the rocks of which are torrefied, and the * ^"J^*"' 



ftate of fcoriie, was not a crater. The rnountains, by tains furround- 



which it is furrounded on the weft, appeared tc me to be of'"g 'tj of the 



the fame nature, without any indication of the mouth from ♦^""^"^^"^^» 



which the fire ifiiied. 



The fummit of mount Agemberg Is very bare, but on The top of 



defcending a few paces, I foqnd a very pleafant copfe. A ^^]^,^'ie^Jf ^^^^* 



narrow path, which I took at a venture, led me, after fome down a pleafant

 By the fide of this grotto is another, inhabited by a hermit, ^"other inhabit- 

 with a table of volcanic ftone in the centre, which he ufes a third in \di'icl> 

 for different purpofes. A little higher up, I difcoveied a 's a" altar, a pi-

 pn one fide was a pigeon-houfe, and lower down, two or bafons of water, 

 three IJttle bafons of water bordered with fliells. 



I quitted this mountain with regret, to traverfe another. Another moun-

 pxifi:ence of a crater; but I could perceive no trace of™''"!^*

My examination was foon finiflied, and I refumed the ^" ^^e road to 

 road to the abbey of Haach. In this I found nothing but Saach^'pumice 

 pumice fipnes, lava; in fome places of the bafaltic kind, ftones, lava, i^ 

 fcoris, a few fragments of hornfione fchifius, and blocks IJfSc,*'l^"is,^*
