With April here,
And first thin green on the awakening bough,
What wonderful things and dear,
My tired heart to cheer,
At last appear!
Colours of dream afloat on cloud and tree,
So far, so clear,
A spell, a mystery;
And joys that thrill and sing,
New come on mating wing,
The wistfulness and ardour of the spring–
And Thou!

Sir Charles George Douglas Roberts
