through the wall of a privy (at O, fig. i.) into which the 
drain dilcharges itfelf. The conductor having palled, in the 
drain, through the hole in the privy wall, was continued about 
three feet into the open fpace under the feat of the privy, 
where it terminated in air, none of the folid work being nearer 
its end than lix inches. As this drain is conftruCted to receive 
the foul water from the yard, and one of the water- cocks is 
near, fome moifture will moft commonly be found in it ; but 
the ftones Hope fo rapidly at the termination of the drain in 
the privy, that any water which runs thither muft be imme- 
diately carried off. This conductor, as well as all the others, 
was kept in its place near the wall in its pafTage down, by ring- 
ftaples driven into the wall. 
The fecond termination we (hall defcribe is that belonging 
to the chimnies F, G, H (fig. i.). The conductor from the 
chimney F in palling down the roof was joined by that from the. 
chimney G (at M, fig. i.) and afterwards by the rod from the 
chimney H (atN, fig. i.) ; thence the iron was continued down 
till it came near the bottom of the wall, where it was turned 
off along the pavement toward a fink (fig. i. QJ not quite 
two feet diffant, through the fide of which it was carried, and 
projecting four inches into the open fpace of the fink, there 
terminated in air. The fink is built of brick, one foot nine 
inches deep, and two feet and a half fquare within j and into 
its fiouth fide is fitted an iron grate, of the fame length as the 
fide externally, and about feven inches deep, the lower part of 
which lies on the bare foil. Through the middle of this grate 
the conduClor paffes, refling in contaCt with one of the bars. 
From its termination to the bottom of the fink is not lefs thau 
twelve inches ; and the bottom, which is of brick, dopes fo 
much, that water can never lie upon it, there being a large
