Commentary
Book Four Winter Poems 277

Seeing icicles hanging from the grasses on the cliffs by the Mashiba River, the poet surmises that snow must have fallen on the high peaks. From the icicles by the nearby river the poet imagines the unseen snow on the summits.
Poems 277 through 293 in this book center on snow, with poems on falconry set among them at 281 through 283.

First line, 'takane ni wa', means on the high peaks, pointing to the distant summits.
Second line, 'yuki furinu rashi', means snow must have fallen, using rashi, an inference grounded in evidence. The poem breaks after the second line.
Third line, 'mashibagawa', is the name of a river, the place of the scene on which the inference rests.
Fourth line, 'hoki no kakekusa', uses hoki, a cliff, meaning the grasses hanging from the cliffs.
Final line, 'taruhi sugareri', means icicles are clinging, closing with the continuative ri. At the start of the snow poems, it sings of icicles as an echo of the poems on ice.
