JACK-DAWS. 81

 and the bird was hawking briskly after flies. I am now 

 perfectly satisfied that they do not aU leave this island in

Tou judge very right, I think, in speaking with reserve 

 and caution concerning the cures done by toads ; for, let

 hit upon the reason ; for, in reality, there are hardly any 

 towers or steeples in all this country. And perhaps, Nor-
