The speaker is searching for a country that exists less on a map than in memory. He knows its hill-springs, wind-stirred elms, dark pines, lanes, and streams with deep certainty. Even in sleep, he feels he could walk those streets sure-footed. The repeated question—“Where is that country?”—is answered quietly: it lies in his mind. The mood is intimate and contemplative, tinged with longing but also comfort, because this inner landscape never fully disappears.
Then the poem turns to a loved person, saying she has become part of that same mental country. Just as his thoughts circle home like a bird, and each present step recalls earlier ones, she now lives inside his history, earth, stream, and skies. Home, the poem implies, is what we carry within us—and whom we carry there.
