Explanation
The chapter presents the poem where the word 'these' appears in both stanzas. In stanza one, the lines 'But clouds that sail across the sky / Are prettier far than these' compare clouds to boats and ships. In stanza two, 'Is prettier far than these' compares the rainbow to the bridges on rivers. The poet uses 'these' as a demonstrative pronoun to refer back to the previously mentioned objects in each stanza.
