Courage and patience are the two virtues most needed by the natives of the Belgian Congo who train and use elephants to procure that extraordinarily valuable product, Every few years the natives must have a round-up to get young to continue the hauling. This story starts with one told from the point of view of bewildered creatures made frantic by the strange ""Ooo-hee"" which they hear from all sides. By far the most unmanageable is Jamba, a vicious beast who will only need a young boy , for a great understanding arises between them. With infinite patience the youth trains the animal until he can take him with the others down into the swamps to drag out the precious wood. One surprising episode is that in which a pigmy tribe catch and eat an elephant. The author of On Safari tells a story well and certainly knows his material.
