THY heart and mine are one, my dear,"Cradle Song" by Florence Earle Coates. Published in Mine and Thine (1904) and Poems (1916) Volume II.
At dawn and set of sun;
When skies are bright, when days are drear,
Thy heart and mine are one!
About us move the hapless folk
Whom paltry things estrange;
The friends that feel their bond a yoke,
The loves that lightly change;
But thou and I, my bonny child,
Their dangers blithely shun,
Nor can by folly be beguiled,—
For thou and I are one!
