"From Friend to Friend"

Dear friend, I know not if such days and nights
Of fervent comradeship as we have spent,
Or if twin minds with equal ardour bent
To search the world's unspeakable delights,
Or if long hours passed on Parnassian heights
Together in rapt interminglement
Of heart with heart on thought sublime intent,
Or if the spark of heaven-born fire that lights
Love in both breasts from boyhood, thus have wrought
Our spirits to communion; but I swear
That neither chance nor change nor time nor aught
That makes the future of our lives less fair,
Shall sunder us who once have breathed this air
Of soul-commingling friendship passion-fraught.
