R. Roskell Bayne —Notes on the remains of [No. 2, 
almost into a creek, compelling me to put in the foundations of the last two 
walls 3, 4 and 5 feet below the other walls, and the soil there was black 
stinking river mud full of pot-sherds, and here we found a great many 
boars tusks of a small size. 
Following the west curtain wall from the north west bastion, and 
about 45 feet from it, we found a Sumph into which the drains all emptied, 
or over which as we found them they all ended. Wc came on to this 
Sumph from behind, and before we actually found out what it was, we had 
destroyed its east face, and the loose filling caved in from the top as we 
cleared it out at the bottom, thus proclaiming its nature. 
The main drain, that running from beyond the Carpenters’ shop, I had 
traced right up to the west curtain wall. I have shewn it in section in fig. 3, 
Plate XII, it was a parallel-sided drain, at the upper end not more than 6 in. 
wide, widening to 13 in. at the lower end, and everywhere filled up with black 
mould. Over it and burying it was a later drain, a broad saucer drain, that 
in its turn had become filled in and buried. The two drains kept the same 
course; it was only the last 75 or 80 feet that the second drain was found. 
The Sumph into which these drains emptied was about 3 ,- 6" square, and as I 
have said, coming on as we did from the side of an opened trench, we had de¬ 
stroyed it in part before we knew what it was, so that we did not see the 
entry of the two drains into it. The parallel-sided and lower drain fell fast 
toward the Sumph nearly 2 feet in 10; where we had cut across it, we found 
it full of pot-sherds, a coarse glazed blue and white ware, not a scrap of old 
willow pattern, square ended broken glass bottles, a black loamy earth, 
and a few very coarse thick pipe stems and bowls. We cleared out about 4 
feet of this drain, tunelling as it were into it and then ceased. 
The Sumph had been filled in with brick rubbish very loosely, so that 
the filling was full of cavities into which water had filtered, leaving on all 
the bricks a thin deposit of clay. This Sumph was nearly perfect up to 
about the second level of floors and material, above the re6t the road ran. 
On emptying this Sumph we found on its western face a low arch with a 
versed sine of about 6 in. and above the floor of the Sumph. Into this opening 
we thrust a rod and found it 3 feet deep with water ; probing 3 feet deep, 
we could feel a bottom of brickwork ; we then tried it horizontally, and 
thrust our rod into vacuity; we tried a second and a third time and at last, 
finding that 20 feet found no end, we concluded it to be a drain. 
As we had found water of which we were in want for our building 
operations, we decided to make use of it, and sank out to the bottom 
of the culvert which we then found to be a parallel-sided drain 26" wide 
and 3 feet 6 high with an arched bottom and top ; on a man trying to go 
into the drain we found it silted up about 2 feet deep. We put up a one 
H. P. Ryder Engine, and for 12 months drew water from this source. The 
water was perfectly clear and limpid. The workmen all drank of it.
