EPOCH OF GREAT GLACIATION 
Across the site of Hebrides to be, 
Finish their course as icebergs in the sea. 1 50 
Another confluent mass to south has gone, 
And joined the ice from Erin working down. 
Then further south these meet the glacier flow 
That down has come from Albion's western snow. 
And further south moves on the swollen band, 155 
And joins a glacier sheet from Cambria's land. 
And thus is held the ground from side to side. 
O'er which is seen to-day the Irish tide. 
Still further south the junctioned masses bear 
An ice united kingdom as it were 1 60 
Till getting out of depth, and climate-worn, 
They tell in monstrous bergs their southern bourne. 
From Erin's central snow- collecting ground 
In all directions have the glaciers wound. 
Indeed in every part, from east to west 165 
And north to south in ice she lies suppressed. 
Meanwhile are other glaciers wandering far 
On divers routes from Scandinavia. 
Some far to north their glassy cargoes bear 
Down sloping vales, coals carrying as it were 170 
To Newcastle. Others south-eastward stretched 
With facile steps have distant regions reached. 
The Baltic basin has not barred their way, 
And far o'er plains of Muscovy they stray.
