Edgar Albert Guest - Service

I have no wealth of gold to give away,
But I can pledge to worthy causes these:
I'll give my strength, my days and hours of ease,
My finest thought and courage when I may,
And take some deed accomplished for my pay.
I cannot offer much in silver fees,
But I can serve when richer persons play,
And with my presence fill some vacancies.
There are some things beyond the gift of gold,
A richer treasure's needed now and then;
Some joys life needs which are not bought and sold—
The high occasion often calls for men.
Some for release from service give their pelf,
But he gives most who freely gives himself.
