Analysis of The Superseded

As newer comers crowd the fore,
   We drop behind.
- We who have laboured long and sore
   Times out of mind,
And keen are yet, must not regret
   To drop behind.

Yet there are of us some who grieve
   To go behind;
Staunch, strenuous souls who scarce believe
   Their fires declined,
And know none cares, remembers, spares
   Who go behind.

'Tis not that we have unforetold
   The drop behind;
We feel the new must oust the old
   In every kind;
But yet we think, must we, must WE,
   Too, drop behind?
