tainous Diftf i6ls of Bou-jeiah ; and brought, in fliort Bars, tb 

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

 Plenty of the Oar upon the Mountains Dwee and Z'lkkar. 

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

 fometimes of Cirinaher ; though no Works have been carried 

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

 The Lead Oars at Jihhel Rtj-fafs near Hammam Leef, at Lead 

 Wannapjreeje^ and among the Beni Bootaleh, 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 extra6l, by thef(^ 

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



The Silver and Copper Mines of the Tingitanians are looked j^^ Copper 

 upon with an envious Eye by the Regencies of Algiers ^ndiTd-^c'over,2 

 Tunis ; though poffibly their own Mountains , by further 

 Searches and Experiments, may be found to contain the like 

 Materials. About thirty Years ago, the Deysoiuf^gkrswQvt 

 encouraged, by fome Spanifli Renegadoes, to fearch for Silver 

 Oar in the Mountain oi Fern an. They would probably have^,,^^ copper. 

 met with better Succefs in trying for Copper, as they have Jt^fJ^er-' 

 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 flioot into no 

 fmall Quantity of Tin Grains. The Mountain likewife of^^wTmoiga. 

 Tmolga abounds with Stones of the fame Quality 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, ai Mahomet a good crop 

 Befs Plowfhares, is applicable enough to This Branch of the pher's st'one 

 Natural Hiftory I am now explaining. ThisPerfon, {whomVlj'!'" ^"""^ 

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

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

 Subjects ; but having the Reputation of being acquainted with 

 the [W6^=] Kymia, (as thefe People call the Philofophef s Stone,) 

 Ibrahim Hojiah, then Dey oi Algiers, engaged to reftore Him 

 to His former Dignity, upon Promife of being let into the
