Your first priming shall be of oaker and Spanish- 

 white, very thinly ground : The second with the same, 

 a little whiter ; but it matters not much. The third 

 and last, with white-lead alone ; some mingle a little 

 Spanish-white with it, but it is better omitted. If you 

 desire it exquisite, instead of lin-seed oyl, use that of 

 wallnuts : But the ordinary stone-colour for gross work, 

 expos'd to the air, may be of less expence, with the 

 more ordinary oyl, to which you may add a little char- 

 coal in the grinding : But if (not much minding a 

 small charge) you desire it more fair and durable, lay 

 your work three times with white-lead, (which is indeed 

 much better than Spanish-white) the first and second 

 primer very thin, yet so as not to run : These may be 

 with lin-seed-oyl ; but the last with nut-oyl, and some 

 oyl of terpentine tempered together, which preserves it 

 from ternishing,and losing colour, (I speak here of work 

 within-doors) : The ordinary priming with red, being 

 a cheat among painters ; seeing white upon white 

 must needs render the colour still whiter and fairer. 



If it be for out-work, and expos'd to the air, you 

 may spare the terpentine, whilst nut-oyl through all 

 the three grind! ngs were most desirable. 



To vein and wave on white, temper a little lamp- 

 black and white exceedingly thin with nut-oyl and 

 terpentine, and then dipping a gentle flexible feather, 

 vein and undulate your work with a light hand, as 

 naturally as you can, to express the veins of marble, &c. 

 either on black or any other ; but the grain of timber, 

 with a slight of the pensil : Vernish, is often us'd, 

 where they paint in size. For other oyl-colours, 



Blew, is made of indigo, with a small addition of 

 red-lead, or verdigriese for a dryer ; unless you will 

 use drying-oyl, which is much preferrable, and is
