"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;
