Growler, lost at sea in February, 1944. Black at that depth turn, golden boy no more white bone to bone, turn hear who bore you weep hear him who made you deep there on ocean's floor turn as waters stir; turn, bone of man Cold as a planet is cold, beat of blood no more the salt sea's course along the bone jaw white stir, boy, stir motion without motion stir, and hear love come down. Down as you fell sidewise, stair to green stair without breath, down the tumble of ocean to find you, bone cold and new among the ships and men and fish askew.

在那深处漆黑一片翻转，不再是金童子白骨连白骨，翻转听听生你的人为你哭泣是他造就了你，你仔细听在大洋深深的底部随着海水的搅动翻转；翻转，男子汉的骨头如行星般寒冷寒冷，血不再脉动盐海的航向沿着白色颌骨搅动，小伙子，搅动没有动作的姿态搅动，并聆听爱降下来向下，当你倒向一侧，梯级到绿梯级没有呼吸，随着大洋的翻滚找到你，骨头寒冷而新鲜，在歪歪斜斜的船只丶人丶鱼之间。
