what trade does Gulliver learn as an apprentice?

Gulliver's Travels (1726, amended 1735), is a novel by Irish writer and clergyman Jonathan Swift (also known as Dean Swift[1]) that is both a satire on human nature and a parody of the "travellers' tales" literary sub-genre. It is Swift's best known full-length work, and a classic of English literature.

The book became popular as soon as it was published (John Gay wrote in a 1726 letter to Swift that "It is universally read, from the cabinet council to the nursery"[2]); since then, it has never been out of print.
