THE Chimney Swallow generally makes its appearance in 

 the south of England early in April, but is seldom seen in 

 Periodical the northern counties, or in Scotland, before the middle or 

 visitant. i a tt er p ar t o f that month. After incubation, and when the 

 young birds have acquired sufficient strength to undertake 

 their long journey, which is the case about the end of Sep- 

 tember, they prepare for their migration to the warm regions 

 of Africa, where they pass the hyemal months. I consider 

 it unnecessary, in the present advanced state of knowledge, 

 to offer many observations on the once prevalent notion of 

 the hybernation of Swallows in this country, as the wonder- 

 ful laws which regulate the migration of birds are alone 

 sufficient to account for the phenomena of their appearance 

 and disappearance at stated periods. From the experiments 

 made, it appears that the Swallows which have been kept in 

 confinement regularly moulted in February^ a fact totally
