so that the finer part of the white lead may gradually sub- 
side. 
A room that will hold one or two pair of good mill- 
stones, with the necessary machinery, to grind the white 
lead first in water : with the shoots, tubs, &c, and uten- 
sils requisite for this purpose. 
A drying room, that requires to be moderately heat- 
ed. 
A room to hold whiting, with which white lead is al- 
ways plentifully adulterated. When added in the propor- 
tion of 10 or even 12 per cent, the lead is not much the 
worse as a paint : but when mixed, as it usually is, to 
the amount of from 20 to 25 per cent, it causes the paint 
to adhere but slightly, and to peel off from the wood. 
A room to hold millstones wherewith the white lead 
should be ground up with whiting and oil, to sell as paint 
ready for use. Much of the profit of an establishment 
may be made to belong to this department of the manu- 
factory. These two mill-rooms might be worked with 
the same machinery ; and the drying room, and whiting 
room should be contiguous. 
There should also be a room separate to prepare and 
contain a stock drying linseed oil, to grind up with the 
lead intended to be sold as paint. 
For this purpose, a stock of litharge, and sugar of lead 
will be wanted, which may be best kept in the whiting 
room. 
A store room. 
A packing room. 
A counting house. 
A cooperage and carpenter’s room. 
A lumber room.
