myriagrammes per annum. The coals cost about 15 cents 

 per myrlagramme at the pits. The mean price at Paris is 

 33 cents. 



Departments of the Pyrenees, Upper, Lower, and Eastern. 

 These three departments have no coal mines worked. 

 Indications have been announced in the department of the 

 Eastern Pyrenees near Prades, and in the environs of Livia, 

 in that of the Lower Pyrenees, at a small distance from 

 Salies; but hitherto they have aflbrded very little hopes. 



Departments of tlie Upper and Loioer Rhine. 



The coal mines worked in these two departments (36) 



are not of much importance. They are, however, valuable 



" for the resources which they afford to thp cantons where 



they are situated. The product of them amounts to about 



200jOOO myriagrammes per annum. 



At Lamperlosch, in the canton of Soultz, in the Lower 

 Rhine, strata of sand containing asphaltum are worked. 

 This bituminous substance is separated, by particular pro- 

 cesses, from the earthy matters with which it is united, and 

 employed in commerce. It is applied to the same pur- 

 poses as pilch, and when mixed with grease is used for 

 daubing over the pivots of machines, axles. Sec. 



Department of the Rhine and Moselle. 

 Several researches have been made in this department in 

 the hope of meeting with coals ; but it does not appear that 

 any mines have yet been worked in it. Some of the coals 

 it consumes are brought from the departments of La Saarre 

 and La Roer, but the greater part come from the mines 

 situated on the right bank of the Rhine. It is estimated tiiat 

 these mines furnish annually 150,000 myrlagrannnes. 



Department of the Rhone. 

 Coal mines are known in several places of tills depart- 

 ment (37), and particularly in that part which borders on 

 tiie department of La Loire. The annual product, how- 

 ever, of these mines amounts only to 50 or 60,000 myria- 

 grammes per annum. 



Department rf La Ro'c'r. 



Very important coal mines arc known at Eschweiller (3S), 

 Cornelins-Munster, W'eisweiller, Bardenberg, and Ifeydcn.
