"Unruly blasts wait on the tender spring;
Unwholesome weeds take root with precious flowers;
The adder hisses where the sweet birds sing;
What virtue breeds, iniquity devours:
We have no good that we can say is ours,
But ill-annexed opportunity
Or kills his life, or else his quality.
O, Opportunity! thy guilt is great:
'Tis thou that execut'st the traitor's treason;
Thou set'st the wolf where he the lamb may get;
