what does lord munodi tells gulliver before he visits the academy of projectors

On Balnibarbi, Gulliver meets Lord Munodi, who invites Gulliver to stay at his home. Munodi's home is beautiful and kept well, but when the two travel out into the country Gulliver finds that the rest of the land is barren and sadly kept. Munodi explains that this is because many years back, people from Balnibarbi visited Laputa, and when they returned they decided to change things to a more academic way of living. This idea has failed. Munodi's land is plentiful because he never changed his way of living.
