tainous Diftrids of Bou-jeiah ; and brought, in iliort Bars^ to 

 the Markets of that Place, and Algiers. They have a great 

 Plenty of the Oar upon the Mountains 7)wee and Zikkar. 

 That of the latter is rich and ponderous, with a Mixture 

 fometimes of C'mnaher ; though no Works have been carried 

 on, as far as I could be informed, at either of thefe Places. 

 The Lead Oars at Jibbel Rij-fafs near Hammam Leef, at Lead. 

 WannapjreeJ'e, and among the Bern Booialeh, are all of them 

 very rich ; and might certainly be obtained in great Quanti- 

 ties, provided their Mines were under a better Regulation. 

 The Method they have to refine It, is by putting Layers of 

 Wood and Oar alternately upon each other ; and fetting the 

 Pile afterwards on Fire, they will frequently extraol, by thefe 

 Means, eighty Pounds of Metal from one Quintal of the Oar. 



The Silver and Copper Mines of the T'lngitanians are looked ^„ copper 

 upon with an envious Eye by the Regencies of Algiers and ,f *^J„tw' 

 Timis ; though polfibly their own Mountains , by further 

 Searches and Experiments, may be found to contain the like 

 Materials. About thirty Years ago, the "Deysoi Algiers wqxq 

 encouraged, by fome Spanifj Renegadoes, to fearch for Silver 

 Oar in the Mountain of Fernan. They would probably have^,,^, ^ί.//»?^- 

 met with better Succefs in trying for Copper, as they have ii^'^fj" ρ"^-' 

 here feveral large Strata of ponderous Stones, tinged all over"^"' 

 with green Efflorefcences. One of the Specimens , that I 

 brought with me from that Place, feems alfo to ihoot into no 

 fmall Quantity of Tin Grains. The Mountain likewife of -^^^ Tmoiga. 

 Tmolga abounds with Stones of the fameQuahty with the for- 

 mer ; being, in all Appearance, very ftrongly impregnated 

 with Copper. But as none of thefe Oars (if they be really 

 fuch) have been put to the Teft, a fmall Share only of fuch 

 Riches, as may be called fubterraneous, can be claimed by thefe 

 Regencies, For the Story, they are pleafed to tell, οϊ Mahomet a good crop 

 Be/s Plowfliares, is applicable enough to This Branch of the plL'^'siine 

 Natural Hiitory I am now explaining. ThisPerfon, (whomKi^.'^" ^'""" 

 have had Occafion, more than once, to mention in the King- 

 dom of Tunis,) had the Misfortune to be dethroned by his 

 Subjedls; but having the Reputation of being acquainted with 

 the [^<^*^= 1 Kymia, (as thefe People call the Philofopher's Stone,)
