‘There through the prison of unbounded wilds,
Barr’d by the hand of nature from escape,
Wide roams the Russian exile. Nought around
Strikes his sad eye but deserts lost in snow,
And heavy-loaded groves, and solid floods,
That stretch athwart the solitary vast
Their icy horrors to the frozen main;
And cheerless towns far distant, never bless’d,
Save when its annual course the caravan
Bends to the golden coast of rich Cathay,
