the other does my sense of hearing. He is the glad pro- 

 phet of the year the harbinger of the best season : he 

 lives a life of enjoyment amongst the loveliest forms of 

 nature : winter is unknown to him ; and he leaves the 

 green meadows of England in autumn, for the myrtle and 

 orange groves of Italy, and for the palms of Africa/ 1 This 

 is, in truth, a brief, but a perfect sketch of the history of 

 the Swallow, and I have only to fill up the outline by 

 adding the details. 



The Swallow is a periodical visiter to this country, and 

 more records are preserved of its first appearance every 

 season than of that of any other bird. The average of 

 many records and many seasons, seems to give the 10th

 more than six months in this country, frequently on its 

 return revisiting the precise locality it had inhabited for

 board the Delaware, near Gibraltar, March 20th, 1828, it 

 is stated that a few days before, being five hundred miles 

 from the coasts of Portugal, and four hundred from those 

 of Africa, we were agreeably surprised by the appearance 

 of a few Swallows, Hirundo rustica and urbica. The wind 

 had blown a gale from the eastward. In that year the 

 first Swallow seen at Carlisle, as recorded by Mr. Hey-

 wall, as recorded by Mr. Couch, was on the 1 7th. These 

 birds, in crossing the Channel, Mr. Couch observes, reach 

 the land near the shore, and in -misty weather seem to 

 have a difficulty in finding it ; for I have been assured by
