Further along a canal on a Summer's day.
Two damsel-flies are on the tall, flowering rush.
These are the smallest of the British dragon-flies, and they prey on gnats, July-browns and other insects.
Beside the water-vole grow arrowhead plants, and to the left the great water-plantain.
Both have three-petalled flowers.
Their roots are deep in the mud under the water and they are growing in the shallows at the canal's edge together with the rushes.
The canal passes under a bridge and there is the tow-path that also goes under it so that a horse that pulls a barge can pass thereon.
On the towpath fishermen are sitting, and one of them has just caught a fish; not too big to be landed with a skilful jerk.
