How does Susanna Rowson use imagery in Charlotte Temple?

Example of Imagery:

" 'She is the sweetest girl in the world,' said he, as he entered the inn. Belcour stared. 'Did you not notice her?' continued Montraville: 'she had on a blue bonnet, and with a pair of lovely eyes of the same colour, has contrived to make me feel devilish odd about the heart.'
