The Water-wagtail. 53 



sun ; for at the sources the aquatic grasses bend 

 over, growing thickly, and hide it from view. But 

 pressing these down, and parting them with the hand, 

 you may trace the exact place where it rises, gently 

 oozing forth without a sound. 



Lower down, where the streamlet is stronger and 

 has worn a groove now rushing over a floor of tiny 

 flints, now partly buoyed up and chafing against a 

 smooth round lump of rubble there is a pleasant 

 murmur audible at a short distance. Still farther 

 from the source, where, grown wider, the shallow 

 water shoots swiftly over a steeper gradient, the un-

 the coombe eat off the herbage too closely to permit 

 of many flowers. Where the springs join and irri- 

 gate a broader strip there grows a little watercress, 

 and some brooklime, said to be poisonous and occa-

A water-wagtail comes now and then ; sometimes
