as high as it could be, unlefs the drains fhould at any time be 
flooded ; and upon meafuring the dittance from the bottom of 
the drain coming from the fore-court (V2, fig. 1.) where it 
terminated in the fide of the cefs-pool, down to the furface of 
the water ftagnating in the cefs-pool, we found it 3I feet. 
This interval, therefore, of three feet and a half muft be patted 
through, to form a communication between the water in the 
drain, and that rn the cefs-pool. The drain is firmly built of 
brick and mortar (fee the fe&ion of it, fig. 7.). To determine 
the nature of the foil in which it is laid, a hole was dug in the 
fore-court feven feet deep, where we found nothing but land,' at 
this time pretty moift, with a few pebbles. There is reafon to 
believe, however, from the foil of an adjacent declivity to the 
northward, that below thefand, perhaps at the depth of 1 5 or 
16 feet, a bed of clay would be found. 
Againtt the eaft flank, near the corner T (fig. 1.), th'ererifes 
a leaden pipe with a cock (O, fig. 2.), to which the water is 
conveyed from a railed cittern (fee r, fig. 1.) in one of the de- 
tached offices of the back-court. A' main of lead from the 
cittern, which is itfelf of that metal, after fending out pipes • 
to fome other cocks, and patting through the cellars of the 
houie, comes into the fore-court about four yards from the 
corner T (tig. 1.) and is carried over the drain at tl^e dittance of 
about a foot above its crown, and eight inches below the fur- 
face of trie ground. Here it divides into two branches, one of 
which goes ttraight to the cock at O (fig. 2.), and the other 
runs wettward, to fupply a ttmilar cock in the oppolite corner. 
We meafured the dittance of thefe pipes and cocks from 
the conductors, and found that they came no where nearer 
than five feet and an half.-
