6 o, And the more efFeftually to prevent the fmoke 
from coming at the milk, it may be well to have 
the broad outer rim of the pans turned perpendicu- 
larly downwards, three or four inches, that it may 
enter deep into a circular groove of fand ; and if it 
lhall be needful, the fand may be wetted in order the 
more effectually to prevent the paffage of the fmoke. 
I thought of this method about fifty years fince, on 
tailing the fmoaky butter in Somerfetfhire. By the 
fame means the poor might fave much fuel in boil- 
ing the pot, efpecially in fummer, when a fire is 
wanted only for boiling the pot. 
6 r . When any pans are to be removed from the 
floves, the afcent of the fmoke through the unco- 
vered flove may be prevented by firfl doling the 
flue near the fire, by an iron Aiding -fhutter or re- 
gifter. 
62. Milk might thus mofl commodioufly be 
heated to a fcalding heat with little fuel, fit for ven- 
tilation, in a veffel of a proper depth, fet in the fame 
manner as the pans in a flove, to fecure it from 
fmoke, with bellows fixed properly near it : (fee 
Plate X. Fig. 3.) By this means there would be 
little trouble or expence in curing ill-tailed milk by 
ventilation. 
63. May 14th, merely to fee what the event 
would be, a gallon of new milk juA from the cow 
was ventilated, for an houn and half, which pro- 
duced fix ounces of butter; and though it was ven- 
tilated half an hour longer, yet no more butter was 
made ; it was whitifh, wanting both the colour and 
tafte of good frefh butter.
