PLATE CLVIII. 



The Swallows of our cities, blackened and difcolourcd with the 

 fwarthy vapours of our chimnies exhibit an appearance only of 

 footy blacknefs, varied with fpots of a dingy white. When in a 

 high ftate of plumage the Swallow is really a very beautiful bird» 

 the black being of a jetty blacknefs, finely glofTed with fhining blue^ 

 partaking in different lights of puiple and azure, and the white of 

 unfullied purity ; the front and chin a rich brown inclining t^ 

 chefnut. 



Varieties of the Swallow wholly white, occur occafionally, and 

 are not more uncommon than the white varieties of the common 

 birds in general. The Swallow is fix inches in length: it has two 

 broods in a year ; the eggs from four to fix in number, of a white 

 troiour, and fpeckled with reddifh. Its chief fubfiftence confifls of 

 infe6is.
