Of the gladdest moments in human life, me thinks, is the departure upon a distant journey into unknown lands. Shaking off with one mighty effort the fetters of Habit, the leaden weight of Routine, the cloak of many Cares and the slavery of Home, one feels more happy. The blood flows with the fast circulation of childhood. A journey, in fact, appeals to Imagination, to Memory, to Hope — the three sister graces of our moral being.
