day this species still nests where it has for years in the chasm 

 called " Purgatory " at the westerly end of the Second Beach, 

 Middletown (see Frontispiece) ; building their nests in the little 

 inaccessible crevices of the vertical walls, where they usually

 rock. No Cliff Swallows (Petrochelidon lunifrons) breed in this 

 chasm, a place apparently more suited to them, than to the Barn 

 Swallows.
