Co'il Mines worked in France. I59 



defTos, diftinguifhed by his knowledge and his zeal for im- 

 provinj the iron manufaftory, has announced indications of 

 coal at^Montefquieu near Fo'ix ; and Duhamcl, the engineer, 

 has found I'oaie alfo at Mas-'dAzil. 



Department of /lube. 



No coal mines are worked in Aube : the general compofi- 

 tlon of the ftrata of the earth, which exhibit only chaik or 

 beds of (hells, affords no reafon to conceive any hope of dif- 

 covering colle&ions of this combuftible mineral, unlefs it be 

 at great depths, and after having traverfed the whole thick- 

 nefs of the beds of chalk and (liells. 



It receives no coals but thofe which are conveyed on the 

 Seine, or which are carried up by La Marne and the river 

 Aube. 



Department of Aude. 



Coals are found in the neighbourhood of Cafcaftel (8), 

 Quintillan, Ruchan, and the mountains of Fabrezan. ^ 



The mines worked near Cafcaftel, Quintillan, and Segur, 

 furnifli about 14000 myriagrammes of fuel per annum. 



The produ£li of the other mines are not known, nor do 

 we pofTel's any certain information refpcfting the price at 

 which the coal? are fold. It is probably very low, beciufe 

 there is very little confumption for thefe mines. 



The proprietors complain loudly of the roads, and wiih 

 they were repaired ; which would facilitate the tranfportatioa 

 of coals to Perpiirnan. 



It would be uieful alfo, if it were poflible, to provide 

 means for conveying the produdts of the mines of Fabreian 

 to the banks of the Aude. 



Department of yk-ejron. 



This department (g) is one of the moft abundant in coal 

 mines. It is interciling alfo on account of feveral other mi- 

 neral fabllances, and particularly of thofe proper for fupply- 

 ing fulphales of alumine and of iron (common alum and 

 green copperas), which are found there in great plenty in the 

 cantons of Milhau, Saint-Affrique, and feveral others.^ 



The collections of coal known near Craiifac, Vialarcts, 

 Livignac, and Mnntignac, and the neighbouring places oa 

 the border;; or at a little diftance from the river Lot, arc ine.x- 

 hauftii)Ie, and for the moft part can be very cafily c.vtrafted. 



In the year 3 llieie mines produced above 500,000 myria- 

 grammes, and the price was not mure than live cents per 



niyria-
