The author studies to learn the language. The Houyhnhnm, his master, assists in teaching him. The language described. Several Houyhnhnms of quality come out of curiosity to see the author. He gives his master a short account of his voyage.

My principal endeavour was to learn the language, which my master (for so I shall henceforth call him), and his children, and every servant of his house, were desirous to teach me; for they looked upon it as a prodigy, that a brute animal should discover such marks of a rational creature. I pointed to every thing, and inquired the name of it, which I wrote down in my journal-book when I was alone, and corrected my bad accent by desiring those of the family to pronounce it often. In this employment, a sorrel nag, one of the under-servants, was very ready to assist me.
