Couriers

Chambers's Encyclopaedia, Volume 3: Catarrh to Dion, p. 524

Couriers are persons hired to accompany travellers abroad, whose special duty is to make all arrangements for the journey, and relieve their employers as far as possible of all anxiety about passports, exchange of money, hotel negotiations, and the like. The speaking of several languages is one of many important qualifications in a good courier.—King's or Queen's Messengers are sometimes called Foreign Office couriers.
