Having objections to the Linnaean classification and principle 

 of nomenclature, I beg to submit the above, as at least prefer-

An Account of the Inuiidation of a Coal-work at Beaujonc, near 

 Liege, belonging to Messrs Colson and Company, and of 

 the remarkable escape of a number of the Miners*. 



On Friday the 28th of February 1812, about half past 10 in 

 the morning, the colliery situate in the parish of Ans, near the 

 Brussels road, about a mile and a quarter from Liege, was inun- 

 dated by a body of water, which forced itself past one side of 

 the frame-dam, constructed in the Rosier seam of the Trique- 

 note pit, which lies about a furlong off that at Beaujonc. 



The water coming from the Rosier seam, flowed over that of 

 Petsay, and from this fell down the Beaujonc pit into the Ma- 

 rias seam, in which 127 men were at that time at work. The 

 fall of water was therefore nearly 87 yards, which is the distance 

 between the Petsay and Marias seams. The serrement, or frame- 

 dam, is a sort of wooden dike, made to keep back the weight of 

 the water which collects between the two estates, and especially 

 in the seams which have been wrought out. The bure-pit or 

 shaft is a great oblong well, having its angles usually rounded 

 off. The seams are more or less thick, as well as the distances 

 between them. The corf is a strong square box, which is borne 

 by chains at the four corners. These are hooked to a great 

 chain, which is moved by ten horses yoked to the machinery. 



The moment a full corf had been drawn up, Matthew Lay- 

 beye, the filler, observed the water falling down the shaft, which, 

 from the surface, is 185 yards deep. His fellow- workmen for a 

 moment thought that the pipes of the steam-pump were choked, 

 and that the water thus prevented from being drawn to day, 



" The above interesting and affecting narrative is extracted from a French 

 pamphlet, published at Liege, and communicated to us by Mr Bald.
