いかにしてしがらみかけむ天の川
流るる月やしばしよどむと

Roma-ji: Ika ni shite shigarami kakemu amanogawa nagaruru tsuki ya shibashi yodomu to
English Translation: How can I contrive
to set a weir across it,
the River of Heaven,
so the moon that flows along
might linger for a while
Meaning: How can I set a weir across the River of Heaven, so that the moon flowing along it might pause for just a while?
Commentary: Book Three Autumn Poems 190

If a weir were set across the River of Heaven, perhaps the moon that drifts westward along it as if carried by the current would pause for a while; the poet longs to find some way to set one. Seeing the moon crossing the sky as something flowing down the River of Heaven, he expresses his regret at its setting.
Poem 247 in this book likewise calls for a weir across a mountain stream to hold back the autumn leaves, sharing the conceit of stopping what flows away with a weir.
From poem 174 through poem 217 in this book a long sequence of moon poems follows, from the evening moon through the bright moon of the fifteenth night of the Eighth Month to the moon at dawn, singing of the moon in all its aspects and of the heart that gazes on it.

First line, 'ika ni shite', means by what means, answering mu in the second line and showing the poet searching for a way.
Second line, 'shigarami kakemu', uses shigarami, a weir of stakes woven with bamboo or brushwood: how shall I set a weir? Poem 247 in this book also has 'set a weir'.
Third line, 'amanogawa', is where the weir would be set. The poem breaks after the third line.
Fourth line, 'nagaruru tsuki ya', means the moon flowing along it, likening the moon's westward passage to drifting downstream, with the questioning particle ya.
Final line, 'shibashi yodomu to', means hoping it might pause a while, yodomu meaning for a current to stall.
