On the fouth-wefl; fide of Whitehaven, in the part called 

 Prefton Ifle, there appears to be coal enough to fupply exporta- 

 tion at the prefent rate for near two hundred years to come. 

 There are three day holes, called Bear-mouths, where the men 

 and horfes go from the furface down a floping cavern to the 

 works ; they are made into the different feams of coal. By 

 thefe entrances horfes are daily brought down, to draw the coals 

 from the places where they are hewn, in waggons, along a waggon 

 way under the ground, made as beforementioned, to the bottom 

 of the refpedive pits, where they are put into baikets, and 

 drawn perpendicularly up to the earth's furface by fleam engines, 

 through a fpace of near three hundred yards in depth in fome 

 places. Each engine performs what twenty-four horfes ufed to 

 do formerly. The men alfo walk -up and down thefe caverns 

 to and from their work, which is much eafier and lefs trouble- 

 fome than being let down and drawn up through the pits each 

 night and morning, which was formerly done. In fhort every- 

 thing is moft wonderfully contrived to fave labour and ex- 

 penfe.
