night for the first birds of the season; let him wan- 

 der all day in or about tangled thickets and sheltered, 

 sunny hill-sides ; let him, with sleepless eye, scrutinize

 every faint chirp and far-off twitter, and follow up every

 sometimes later by two weeks, and sometimes absent al-

 as to both time and seasons, and so, too, does the hermit- 

 thrush, which, however, occasionally remains throughout
