When Phileas Fogg makes the sudden decision to take on the challenge of traversing the world in eighty days, he has no time to lose. Therefore, he decides to take very little with him in the way of luggage. He tells Passepartout:
We'll have no trunks; only a carpet-bag, with two shirts and three pairs of stockings for me, and the same for you. We'll buy our clothes on the way.
Fogg also tells his valet to bring along his traveling cloak, walking ("stout") shoes, and mackintosh (what we would call a raincoat), though he is not planning to do much walking.
In addition to these items, Fogg brings a railway guide and money, described as follows:
Bradshaw's Continental Railway Steam Transit and General Guide, with its timetables showing the arrival and departure of steamers and railways. He took the carpet-bag, opened it, and slipped into it a goodly roll of Bank of England notes, which would pass wherever he might go.
All of this is quite startling to Passepartout. Not only had he relied on have a quiet, predictable life with Fogg, in those days a rich person would typically travel with many trunks of clothing. Further, when the valet finds out that the thick wad of bank notes is in the amount of 20,000 British pounds, he almost falls over. That represents a vast fortune in the late-nineteenth century.
Fogg, of course, is relying on his money to solve any problems they might encounter in their race around the globe.
From the start, Fogg shows he is generous with his money, giving a substantial sum to a beggar and buying first class train tickets. He also shows he is wise, determined, and clear-thinking in traveling light so that they don't get weighted down with inessential items.
