On Thursday it started to rain and didn't stop for a week. But they just carried on in the rain.

The masons worked on in the rain building up the stone wall. Luckily the eaves overhang partly protected them.

On Thursday afternoon the inspector of drains from SPANC, Mme Berthome, came to check everythng. She was not satisfied with the proposed arrangements for the ventilation of the tank and insisted that a separate 100mm ventilation pipe was provided to above roof level.
