To-morrow is that lamp upon the marsh, which a traveller never reacheth;
To-morrow, the rainbow's cup, coveted prize of ignorance;
To-morrow, the shifting anchorage, dangerous trust of manners;
To-morrow, the wrecker's beacon, wily snare of the destroyer.
Reconcile conviction with delay, and To-morrow is a fatal lie;
Frighten resolutions into action, To-morrow is a wholesome truth.
