cents per myriagramme, delivered at the mine. There are 

 very few means of difpofing of them. 



Dcpartinent of the Upper Alps, 



Coal mines are found (4) in the commune of Saint Martin 

 de Querieres, and in the neighbourhood : the fame obferva- 

 tions may be applied to thefe coal mines as have already 

 been made in regard to thofe of the Lower Alps. They have 

 however a more certain and an eafier fale, in confequence of 

 the neighbourhood of the town of Brianpon, where the con- 

 fumptiou is very confiderable, as wood is exceedingly fcarce 

 in that canton. 



Department of the Maritime Alps. 



A grant was palled in the year 9, of tlie coal mine (5) in the 

 neighbourhod of Roquebrune. The grantee has lately an- 

 nounced that the firft attempts were not fuccefsful. It, 

 however, appears that fome of this fuel is dug up in feveral 

 places in the neighbourhood of Monaco. Thele mines might 

 acquire a certain degree of importance, if the coals were of a 

 good quality, and if thev were exported through the port of 

 Monaco, or if manufaftories of iron articles were eftabliflied 

 in that department, or in the environs of the mines. 



If the iron ore of the mines of Elba was treated in this de- 

 partment, or in that of Var, the iron obtained might give 

 rife to manufaftories of this kind ; but thefe confiderations 

 require farther information, which will no doubt excite the 

 attention of govermnent. 



Department of Ardeche. 



CoaIs are found (6) in feveral cantons of this department, , 

 and particularly in the environs of Jaiijac, Privas, Aubenas, 

 Vallon, and Saint Marcel'd'Ardeche. Thefe mines, in gene- 

 ral, are badly worked. They are interefting, however, in 

 di fie rent points of view; firft, on account of the confumptioa 

 occafioned bv the numerous manufa£lories of the country ; 

 and in the fecond place of the facility of carriage down the 

 Rhone. 



No data fufficiently exaft have yet been obtained in regard 

 to the produils of thefe mines: they arc certainly confiderable, 

 and would become much more produftive and profitable, if 

 the works were better conducted. The common price of 

 coals in that country is about 8 cents per myriagramme. 



An engineer of mines, if fettled in this department, might 



introduce improvements in the working of thefe coal mines, 



which are exceedingly defirable. He could employ himfelf 



alfoon other objects ufeful to the induftry of the inhabitants.
