228 THE BIRDS OF IONA AND MULL.

 knoll, whence they keep calling and re-echoing each other's cry, so 

 that such favourite spots often get named after them, as Mono,' chuich, 

 the cuckoo's moor ; Dun chuich at Inveraray, Penicuik, kc. 



The Goatsucker. 



Is not common, though I have heard them buzzing in the stunted 

 underwood which grows in patches among the rocks of West Mull, 

 and have taken its solitary egg lying on the bare ground.

The Swift. 



Is not a common bird, though one pair have a nest in the tower 

 of Iona Cathedral. 



I extract the following from a little book on ornithology, published 

 in 1807, as illustrating the idea people had of birds migrating sixty

 great while untired in the air. This makes their migration probable. 

 They pass, as is believed by some, to France, and thence they can by 

 easy journeys reach Gibraltar, whence their passage to Africa is very 

 short. Others, however, have collected facts, or made observations 

 which they believe establish their opinion that swallows do not 

 migrate, but remain torpid either under water, or in the hollows of
