Robert Silliman Hillyer - "Even as love grows more, I write the less" lyrics

Even as love grows more, I write the less, Impelled to speak, unable still to voice The lyric thoughts like angels that rejoice Attendant on thy godly loveliness. Stay the bright swallow high in airy poise, Carve out of stone an infinite caress, Garner the fruits of tears and happiness, Make bloom forever what an hour destroys, Then shamed by such unprecedented sk** I may find words to name thee, and to sing Such praises of thy beauty as shall fill The listening world with floods of carolling; Till then thou art like starlight on the air, Or clouds at dawn, unutterably fair.
