In the fourth chapter of his accounts, the author describes the intricate measures taken to ensure his safe transit within the land of Brobdingnag. To facilitate his travels, the Queen commissioned a "traveling closet," a specialized box measuring "twelve feet square." This structure was designed for both security and comfort, featuring "iron wire" on the windows to prevent mishaps and furniture—including chairs and a table—that were "screwed to the floor" to withstand the motion of travel. Glumdalclitch, his devoted nurse, often transported him in this manner, though she would occasionally place him in her hand to provide him a better vantage point of the "houses and people" as they navigated the streets.
Despite the relative comfort of his life, the author emphasizes that his "smallness" frequently led to "ridiculous and troublesome accidents." The most harrowing of these involved a "monkey" belonging to a kitchen clerk. On a warm day, with the windows left open, the creature entered the author's living box. The author describes the animal as behaving much like a cat with a mouse, "peeping and grinning" before grabbing him by the coat.
What followed was a harrowing ordeal: the monkey "clambered up onto the roof," holding the author "like a baby in one of his forepaws." The palace descended into an "uproar" as servants scrambled for ladders. During this time, the monkey attempted to feed the author "leftover food" he had stolen, an act the author found both humiliating and physically distressing. The scene was a source of great amusement for the onlookers below, who were "laughing" at the absurdity of the situation.
When the monkey was cornered by the arriving servants, he dropped the author on a ledge "500 yards from the ground." The author narrowly escaped death, though he was left "sick and bruised" from the experience, requiring a week of recovery. His nurse, Glumdalclitch, provided essential care, using a "small needle" to remove the "filthy stuff" the monkey had forced into his mouth.
Upon his recovery, the King inquired about the author’s perspective on the event, specifically asking how he would have handled such a situation in Europe. The author, attempting to maintain his dignity, boasted that he would have used his "knife" to wound the beast. He described the monkey as being "as large as an elephant," highlighting the extreme disparity in scale. Despite the author's attempt to speak "as bravely as I could," his claims were met with nothing but "laughter" from the court, underscoring the vast cultural and physical divide between the author and his giant hosts.
