Viz. Of all Manner of Mines and Minerals, from the Gold to the Coal; with plain Directions and Rules for finding of them in all Kingdoms and Countries. And also, The Art of Melting, Refining, and Assaying of them is plainly shewn; so that every Man of an ordinary Capacity may, with a small Charge, presently try the Value of such Oars as shall be found either by Rule or by Accident. To which is added, A real Experiment, whereby every one may presently try whether any Piece of Gold that shall come to his Hands be true or counterfeit, without defaceing or altering the Form thereof, and more certainly than any Goldsmith or Refiner whatsoever can do. Also A perfect Way to try what Colour any Berry, Leaf, Flower, Stalk, Root, Fruit, Seed, Bark, or Wood will give; with an infallible Method of preparing Colours, which shall neither stain, nor fade, like ordinary Colours.

I have thus try’d many Oars, and have found them to differ in Good- nefs of all Sorts, from forty Shillings worth worth of Silver in a Tun to thirty five Pounds worth of Silver in a Tun, and there is no Lead but it holdcth fome Silver, ret it is not worth the Refining, unlefs it yield eight of ten Pound upon a Tun at leaft. The Tcfl may thus be made : Firfl, let a Smith make a Ring of Iron about four Inches wide, and two Inches deep, and a quar ter of an Inch thick, and as wide above as be neath, and without a Bottom. Then burn Mutton and Beef-bones in the Fire till they be white ; then beat them fmall in a Morter, and fearce them fine like Meal ; then with a little Beer or Water temper a fmall Part thereof like Pap, then, put fo much more of the dry Powder by little and little, as will make it fo flifF that it will be made into a Ball,, but remain clammifh, betwixt Powder and Pafle ; then with a Peflle flamp it gently into your Ring till it be Top-full, being fet upon an every Board, then flamp it a little lower in the Middle, then at the Edges, and fmooth it with, a flight Stone, or fome round Glafs, fo fet if in the Chimney Corner, to dry a Day or two, and it is ready for your Work.
