Barton Pavement

Floor below level of ground 1'-10" 1.7"} in two places

The floor was damp no worms.

It was arched in places, by the swelling of the vegetable fibre between tesserae I suppose.

On the top of the mortar between the tesserae, a little sand in a few places evidently brought up by something from below the floor was very wavey

Worms at work on grass between stones the hypocaust.

The hypocaust was hollow from what the woman says.

Judging from pieces of detached tessarae with the concrete; worms could not get through it.

In this room there was turf over the pink concrete turf was about 1 1/2" thick

Found worm hole going right through pavement we measured it 2 1/2 below level of tessarae & it went deeper.

Worm made very few castings here.

Found a worm coiled up 3 1/2' below about where the floor was in rotten concrete & worm uncoiled. We found no tessarae
