and beginning to sing, it is an easy bird to see, and not 

 difficult to shoot. On its first arrival, it often warbles in an 

 undertone so low, that you fancy the sound must be muffled 

 by the thick tangle of branches in which you think the bird 

 is concealed, while all the time it is perched on high upon

 the melody that he pours forth. Sometimes he will sing

 Our afternoon walk was more fruitful of result than had 

 been our morning's. I had followed for some time the shore 

 of the overflowing Petchora, when, after having bagged a
