i8 OF THE WATERS. 



is of an atramentous tafte, owing to an alcaline cretaceous 

 earth. 



At the village of Hafyivell, near Seatait-DetavaL, in a field called 

 the Park, is a fpring of fimilar qualities, and would undoubtedly 

 be as efncaceous in the fame complaints, but it is not put to any 

 medical ufe that I hear of. It is of a ftong atrarnentous tafte, 

 and turns to a deep purple with galls. It is dedicated to St. Mary t 

 and is called the Haly-Wdl ; from which the village takes its name. 



In the {lone-pavement of the rivulet, on the north-fide, next 

 the village, is a vitrioline fpring, very perceivable in a dry fum- 

 mer, rifmg in perpendicular bubbles ; a yellow ochre, or mar- 

 tial earth, plentiful on the pavement by it. It is of an irony 

 tafle. 



There is another of the fame kind a little higher up the rivu- 

 let, by a flate-quarry. They are both known to the neighbour- 

 hood, but not ufed. They give a purple with galls. 



Befides thefe chalibeate vitrioline fprings, we have others, 

 which, from their remarkable charge of fulphur and foetid tafte, 

 are called Sulphur-Springs. 



By the rivulet of Wark, in Tyned-ale, near Rofe's Bower, is a fpring 

 fo impregnated with fulphur, that the fcent of it is perceiveable 

 above two hundred yards in hot droughty weather. A blue fedi- 

 ment is then at the bottom, which being rubbed on one's fingers 

 makes them of the fame colour. The fides are tinged with an 

 ochreous yellow. The ftones and herbage, warned by its cur- 

 rent, are of a filvery hue. With an infufion of galls it turns to 

 a deep purple, and with fyrup of violets to a faint green. It is 

 unaffected with oil of tartar per ddiquium, and with fal ammoniac.
