PIT COAL. 



A letter from Salisbury, in Virginia, North America, 

 states, that the strata of coal there are near the surface of the 

 earth, and very thick. One stratum was lately discovered of 

 the astonishing thickness of 42 feet, and so near the surface, 

 that the earth is merely taken off, and the coal dug out with- 

 out undermining. 



The last winter was the mildest and driest ever known in 

 America. 



MUNGO PARK. 



In the beginning of the present month (July) a letter was 

 received from the River Gambia, stating, that Mungo Park, 

 the traveller, and his retinue (two or three excepted), had 

 been murdered by the natives in the interior of the country. 

 This news is stated to have been verified by the arrival of the 

 persons who escaped the massacre, at Widah.
