DEVONIAN PERIOD 
Meanwhile great parts of Albion scale the sea, 1 50 
And stretch their breadths to Belgia's territory, 
And Francia's northern parts ; whilst on the west 
Their creeping shores to Erin's lands have pressed. 
Thus up and down, as through the time to be, 
With varied fortunes move the land and sea. 155 
And goes not slowly on such change to-day, 
As Earth to rest pursues her troubled way ?
