as low as pofTible, both on account of their utility in our ma- 

 nufaftories, and of the ueceHity of" maintaining a competition 

 with the Englifh coals. 



The carriage by the caufevvays from Charleroi and Mons 

 to Brufl'cls adds greatly to the price of thefe coals. A canal 

 has been projected for uniting the Sambre towards Thuia 

 with the fniall river of Senne ; which would convey the coals 

 of the mines in the neighbourhood of Charleroi to Bruflels, 

 and would thus form a communication with the Scheldt and 

 Batavia, fo as to prevent the neceffity of land carriage. 



This canal, vakiable in this point of view, would be of 

 utility alfo to the export trade of thefe countries in regard to 

 the glafs and nails feni to Holland and to our own ports, and 

 which are thence conveyed to the Indies. 



It would be of utility alfo to government for tranfporting 

 the timber of the Foreft of Souane, through which it would 

 pafs. 



To point out thefe improvements will, no doubt, be fuffi- 

 clent to induce government to pay ferious attention to them ; 

 but until new means of circulation be provided, it is of imr 

 portance that the exiting roads fliould be properly repaired. 



I (liall terminate this article by obferving, that it is the in- 

 tereft of France to facilitate its commercial intercourfe with 

 Holland, and particularly that which relates to the importa- 

 tion of our coals into that country : conlequently, inftead of 

 laying a duty on their exportation to the amount, as is faid, 

 of 20 per cent., this branch of commerce ought to be entirely 

 free. It would be good policy alio to encourage by bounties 

 the exportation of the coals of this department, efpecially 

 when deftined for French ports in parts of our territory which 

 cannot receive this fuel from the mines of the interior, and 

 which if not lupplied by our mines would procure them from 

 foreign countries.
