The love of travel was a family instinct, and was born with me. My maternal grandfather went to Central Africa-at least, he left us intending to do so, but never came back again. I had a great uncle who voyaged three times round the world, and one sailor uncle who, half a century ago, spent a winter at the North Pole along with Parry and Franklin. Then I had a cousin who was very ambitious of reaching the moon, and spent his life in studying its maps and making preparations for the journey, which, however, he never accomplished.
