prostraverit, maximamque cladem cum hominum turn pecorum 

 dederit. Fordun supplies another fact in the history of this tem- 

 pest, by stating that it came on accompanied with a violent north 

 wind, and that its ravages extended from the Tay to the Tweed. 



Such a storm must have left some visible traces of its existence. 

 Tradition, indeed, mentions one of the effects of this mighty flood, 

 in the destruction of a town, and in the elevation of the sands of 

 Barrie, at the mouth of the Tay. And what prevents us from con- 

 cluding that the same mighty tempest raised from the bottom of the 

 channel of the Frith of Forth the oyster and muscles, and deposited 

 them in a regular bed along the banks of the river?
