Each time I begin a book of travel I search for the reasons that sent me awandering. Foolishness, for I ought to know by this time the wander fever was born in my blood; it is in the blood of my sister and brothers. We were brought up in an inland town in Victoria, Australia, and the years have seen us roaming all over the world. I do not think any of us has been nearer the North Pole than Petropaulovski, or to the South Pole than Cape Horn—children of a sub-tropical clime, we do not like the cold—but in many countries in between have we wandered. The sailors by virtue of their profession have had the greater opportunities, but the other five have made a very good second best of it, and always there has been among us a very understanding sympathy ‘with the desire that is planted in each and all to visit the remote corners of the earth. Anybody can go on the beaten track. It only requires money to take a railway or steamer ticket, and though we by no means despise comfort—indeed, because we know something of the difficulties that beset the traveller beyond the bounds of civilisation, we appreciate it the more highly—still there is something else beyond comfort in life. Wherein lies the call of the Unknown? To have done something that no one else has done—or only accomplished with difficulty? Where lies the charm? I cannot put it into words—only it is there, the “something calling—beyond the mountains,” the “Come and find me” of Kipling. That voice every one of the Gaunts hears, and we all sympathise when another one goes.
