| With the weather once again on our
side, progress remained good this week, including the opening of the new
Trench 4. In addition to on-site activity, this week also saw work in the
City archives. Plans, records, photographs and even a contemporary scrapbook
of cuttings concerning the Exhibition Centre were found, and confirmed the
purpose of the walls in Trench 1, as well as helping to place each of the
trenches into the context of the building.
Trench 1
The final demolition deposits were removed from around the foundation
walls, which were cleaned, recorded and photographed. Being only two courses
high, and sat directly onto the clay beneath, the disturbance of the Exhibition
Centre on the earlier archaeology may be less than we had expected.
The walls were removed, exposing the clay used to level the site before
the construction of the Exhibition Centre. Into this, an unknown and irregularly
shaped feature appears to have been cut, though its purpose is unknown.
Finds this week include an unusually intact clay pipe with decorated bowl
and attached stem.

Trench 2
Continuing the excavation of the large levelling deposit occupied the
first half of the week, before the trainees were relocated into other
trenches, where the archaeology was more immediately accessible. Work
on this trench was put on a temporary pause by the end of the week as
a result.
Trench 4
Underneath topsoil and modern rubble deposits, a layer of roof tiles was
uncovered. This was thought to be from the demolition of a medieval building
on the other site of the standing wall. One of these roof tiles was imprinted
with the paw print of a dog. In addition, the concrete edge of the outbuildings
of the Exhibition Centre was identified.

Trench 6
Leaving the pipes intact for the present, the path layers were removed
first this week. In the process, a further three pipes were revealed -
these were probably earlier, relating to the Exhibition Centre. In the
backfill for one of the pipes, a blue glass bead was found by one of the
trainees, possibly Roman in date.

Trench 7
Work started this week on two paths, both cut by the modern pipe excavated
last week. The wall discovered last week was fully uncovered on either
side. Underneath the paths was a deep deposit of garden soil from the
sites use prior to the construction of the Exhibition Centre. A
large well-preserved clay pipe with a Masonic symbol was uncovered among
Roman and medieval pottery from the garden soil.
