8 protection from over-enthusiastic churchyard gardeners. On the way to the A 131 road, I photographed the common aquatic Umbellifer called Fool's Watercress, and then walked along the banks of the River Ter. We encountered some bullocks in a field, one lone individual providing a scare until we approached close enough to see it was not a bull. Looking back across a field we saw the tower of Great Leighs Church, which is one of six churches with round towers left in Essex. The base of the tower is Saxon and the upper part is Norman. It was probably used as a defence against North Sea pirates coming up the Chelmer and Blackwater. It stood at one end of a wooden Saxon church. Onward to Fuller Street, where we were positively welcomed at "The Square and Compasses" on this very hot day. Food and good beer are available at this small pub. Refreshed we set out to cross the Ter, the bridge being guarded by a herd of young Fresians, who followed us across their field inquisitively nosing our bags expecting food. The second day closed at Terling after passing the smock windmill and crossing the very deep ford. DAY 3. 26th August, 1984 A month later the weather was still fine as we began with a botanical pleasure. This was the Lesser Calamint, growing on a dry roadside bank outside Monk's Barn. Fifty per cent of the national population of this plant is found in Essex. It is declining rapidly and needs protection from rotary and flail mowing.
