physical circumstances. By many ornithologists, causal or ac- 

 cidental visitors, as they are often called, are considered of very 

 little importance and as almost unworthy of notice in the Fauna 

 of any country. But on reflection is not this the way in which 

 all or nearly all of our now resident species have at first arrived 

 here, having been driven, or, induced by a law of immigration 

 to the westward, and have thus been brought or introduced into 

 these Islands in very remote times, but at any rate since the 

 Grlacial period, and there seems to be no apparent reason why 

 other casual visitants should not become permanently, or for a 

 time, residents, provided that suitable locality and food be found. 

 Unfortunately our over civilization, drainage of marsh-lands, 

 destruction of forests, and wanton destruction of all the larger 

 wild animals which are supposed, often erroneously, to be of no 

 use or service to man, will prevent any chance-visitor from be- 

 coming a resident and an addition to the Fauna of these Islands, 

 so long as our present civilization lasts.
