106 BIBDS IN CAGES. 



your eye on my last letter, you wilL find that many species 

 continued to warble after the beginning of July. 



The titlark and yeUow-hammer breed late, the latter very 

 late ; and, therefore, it is no wonder that they protract their 

 song ; for I lay it down as a maxim ia ornithology, that as 

 long as there is any incubation going on, there is music. As 

 to the red-breast and wren, it is well known to the most 

 incurious observer that they whistle the year round, hard 

 frost excepted ; especially the latter. 



It was not in my power to procure you a black-cap, or a 

 less reed-sparrow, or sedge-bird, aUve. As the first is 

 undoubtedly, and the last, as far as I can yet see, a summer 

 bird of passage, they would require more nice and curious 

 management ia a cage than I should be able to give them : 

 they are both distiaguished songsters. The note of the 

 former has such a wild sweetness that it alv.'ays brings to my 

 mind those lines in a song in " As Tou Like It :" — 



And tune his merry note 

 Unto the wild bird's throat. 



The latter has a surprising variety of notes, resembling the 

 song of several other birds ; but then it has also a hurrying 

 manner, not at aR to its advantage. It is, notwithstanding, 

 a delicate polyglot. 



It is new to me that titlarks in cages sing in the night ; 

 perhaps only caged birds do so. I once knew a tame red- 

 breast in a cage that always sang as long as candles were in 

 the room ; but in their wild state no one supposes they sing 

 in the night. 



I should be almost ready to doubt the fact, that there are 

 to be seen much fewer birds in July than in any former 

 month, notwithstanding so many young are hatched daily. 

 Sure I am, that it is far othervrise with respect to the 

 swallow tribe, which increases prodigiously as the summer 

 advances ; and I saw at the time mentioned, many hundreds 

 of young wagtaUs on the banks of the CherweU, which 

 almost covered the meadows. If the matter appears, as you 

 say, in the other species, may it not be owing to the dams 

 being engaged in incubation, while the young are concealed 

 by the leaves ?
