To those who meditate Travel.--Qualifications for a Traveller.--If you have health, a great craving for adventure, at least a moderate fortune, and can set your heart on a definite object, which old travellers do not think impracticable, then--travel by all means. If, in addition to these qualifications, you have scientific taste and knowledge, I believe that no career, in time of peace, can offer to you more advantages than that of a traveller. If you have not independent means, you may still turn travelling to excellent account; for experience shows it often leads to promotion, nay, some men support themselves by travel. They explore pasture land in Australia, they hunt for ivory in Africa, they collect specimens of natural history for sale, or they wander as artists.
