So when in tears The love of years Is wasted like the snow, And the fine fibrils of its life By the rude wrong of instant strife Are broken at a blow Within the heart Do springs upstart Of which it doth now know, And strange, sweet dreams, Like silent streams That from new fountains overflow, With the earlier tide Of rivers glide Deep in the heart whose hope has died-- Quenching the fires its ashes hide,-- Its ashes, whence will spring and grow Sweet flowers, ere long, The rare and radiant flowers of song!
