Reason, erudition and emotion having thus conquered, instruction begins. The forethought necessary is as great as if he were choosing a wife. For tutors and horses, it seems, the most that can be expected from them is that they shall not imperil his soul and body respectively. First among requisites is a book of prayers and hymns effective for salvation without being so pugnacious, doctrinally, as to cause suspicion. Next, a note-book, a watch, or a pocket sun-dial; if a watch, not a striker, for that warns the wicked you have cash; a broad-brimmed hat, gaiters, boots, breeches (as if his friends would let him start without any!), gloves, shoes, shirts, handkerchiefs, "which come in useful when you perspire"; and if he cannot take many shirts, let those he takes be washed, he will find it more comfortable. Also, a linen overall, to put over his clothes when he gets into bed, in case the bed is dirty. Let him get to know something of medicine and, "like Achilles," learn to cook before he leaves home. Travel not at night, and, in daytime, be guarded by the official guards which German and Belgian towns provide; or travel in company. Now, the aim of travelling is the acquisition of knowledge; stay, therefore, in the more famous places rather than keep on the move. Enquire, concerning the district, its names, past and present; its language; its situation; measurements; number of towns, or villages; its climate, fertility; whether maritime or not, and possessing forests, mountains, barren or wooded; wild beasts, profitable mines; animal or vegetable life peculiar to itself; navigable or fish-yielding rivers; medicinal baths; efficient fortresses. And concerning towns: the founder, "sights," free or otherwise; what the town has undergone, famines, plagues, floods, fires, sieges, revolutions, sackings; whether it has been the scene of councils, conferences, synods, assemblies, gatherings, or tournaments.
