There is continual spring, and harvest there Continual, both meeting at one time: For both the boughs do laughing blossoms bear, And with fresh colours deck the wanton prime, And eke attonce the heavy trees they climb, Which seem to labour under their fruits load: The whiles the joyous birds make their pastime Amongst the shady leaves, their sweet above, And their true loves without suspicion tell abroad.
