and raine, which makes them slake, and fall to pieces from the centre, and shoot out a pale blewish salt; and then they boile the salt with pieces of old rusty iron. ___________________________________
In the chalkie rocks at Lavington is umber, which painters have used, and Dr. Chr. Meret hath inserted it in his Pinax.

In the parish of Steeple Ashton, at West Ashton, in the grounds of Mr. Tho. Beech, is found plenty of a very ponderous marchasite, of which Prince Rupert made tryall, but without effect. It flieth away in sulphur, and the fumes are extreme unwholsom: it is full of (as it were) brasse, and strikes fire very well. It is mundick, or mock-oare. The Earle of Pembroke hath a way to analyse it: not by fire, but by corroding waters.
Anno Domini, 1685, in Chilmark, was found by digging of a well a blewish oare, with brasse-like veines in it; it runnes two foot thick. I had this oare tryed, and it flew away in sulphur, like that of Steeple Ashton. ___________________________________
On Flamstone downe (in the parish of Bishopston) neer the Race-way a quarrie of sparre exerts itselfe to the surface of the turfe. It is the finest sparre that ever I beheld. I have made as good glasse of this sparre as the Venice glasse. It is of a bright colour with a very little tincture of yellow; transparent; and runnes in stirias, like nitre; it is extraordinary hard till it is broken, and then it breakes into very minute pieces. ___________________________________
We have no mines of lead; nor can I well suspect where we should find any: but not far off in Glocestershire, at Sodbury, there is. Capt. Ralph Greatorex, the mathematical instrument maker, sayes that it is good lead, and that it was a Roman lead-worke. ___________________________________
Tis some satisfaction to know where a minerall is not. Iron or coale is not to be look't for in a chalky country. As yet we have not discovered any coale in this county; but are supplied with it from Glocestershire adjoyning, where the forest of Kingswood (near Bristowe) aboundeth most with coale of any place in the west of England: all that tract under ground full of this fossill. It is very observable that here are the most holly trees of any place in the west. It seemes to me that the holly tree delights in the effluvium of this fossil, which may serve as a guide to find it. I was curious to be satisfied whether holly trees were also common about the collieries at Newcastle, and Dr.. .. . , Deane of Durham, affirmes they are. These indications induce me to thinke it probable that coale may be found in Dracot Parke. The Earledomes, near Downton, (woods so called belonging to the Earledome of Pembroke,) for the same reason, not unlike ground for coale.
They have tryed for coale at Alderbery Common, but was baffled in it. (I have heard it credibly reported that coale has been found in Urchfont parish, about fifty or sixty yeares since; but upon account of the scarcity of workmen, depth of the coale, and the then plenty of firing out of ye great wood called Crookwood, it did not quit the cost, and so the mines were stop'd up. There hath been great talk several times of searching after coale here again. Crookwood, once full of sturdy oakes, is now destroyed, and all sort of fuel very dear in all the circumjacent country. It lies very commodious, being situate about the middle of the whole county; three miles from the populous town of the Devises, two miles from Lavington, &c.-BISHOP TANNER.)
