WITH THE BIRDS IN WALES 121

 able Swallows hawking for flies on the embankment ; 

 which just here is exceedingly steep and well wooded. 

 Saw the usual Heron and the Lesser Black Backs again. 

 I hear that these last appear on the river every year 

 in the early spring, and do not leave it till late on in

 are in mature plumage apparently, and must surely
