“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 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 you can see how the tow-path 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.” NatureSummerStreamBritish Countryside Book:What To Look For In Summer Source: What To Look For In Summer
