Analysis of Sonnet

STILL northward is the central mount of Maine,
From whose high crown the rugged forests seem
Like shaven lawns, and lakes with frequent gleam,
'Like broken mirrors,' flash back light again.
Eastward the sea, with its majestic plain,
Endless, of radiant, restless blue, superb
With might and music, whether storms perturb
Its reckless waves, or halcyon winds that reign,
Make it serene as wisdom. Storied Spain
Is the next coast, and yet we may not sigh
For lands beyond the inexorable main;
Our noble scenes have yet no history.
All subtler charms than those that feed the eye,
Our lives must give them; 'tis an aim austere,
But opes new vistas, and a pathway clear.
