The steadiness of llamas, the power of horses, the strength of elephants, the endurance of camels, the muscle of oxen, the teamwork of huskies, the toughness of donkeys—all these features make for outstanding workers, haulers, or pack animals. For thousands of years, people have ridden animals for transportation, or loaded goods on the back of a pack animal for the journey to market. Other animals are employed for their strength—animals such as oxen and elephants pull carts and plows, wagons loaded with people, tree trunks, and even rocks along dirt roads, muddy paths, and in thick jungles. With full-colour photographs, illustrations and boxes containing key items of information, each volume of Working Animals provides an attractive yet informative guide to how animals and humans work together.
