How did it use echoes to find its prey in the ocean gloom, to stun fish, diagnose illness in another whale? Questionsto which the answers could prove invaluable. But instead of learning, men threatened to wipe the species out. Aboard the catcher boat no such thoughts crossed the gunner39。s mind. He was busy trying to solve a sixty foot, sixty ton problem: a sperm whale that refused to give up. The harpoon had not found the vital spotthe gunner blamed the choppy sea for spoiling his aim and now the whale was towing the 110 ton boat behind it. Even with the engine reversed, the craft kept moving forward. The gunner got ready to fire a second harpoon. In the bloodstained water the mammoth beast continued its agonising struggle. He was a mature male, a bull. His slate blue body bore scars, souvenirs of epic battles with giant squid he had hunted in the dark depths. The biggest of these pink monsters, whose humanlike eyes were more than fifteen inches across, weighed 42 tons and measured 66 feet. But even the ir powerful beaks and ten suc kered tentacles were no match for the whale39。s eightinch teeth. ted on the shore. Someone set it ablaze. Spar ks crackled amid whirling smoke. Excited, cherry cheeked children ringed the bonfire。 only the older ones understood that this was no celebration. For several nights to e there would be plenty of bodies to feed the flames. Niy miles inland, nothing broke the forest hush. A full moon silvered the treetops and light leaked down to the snowcovered floor beneath. Scraps of mist seemed caught on prickly branches. From the shadows, a ghostly shape glided into a clearing. Tw o amber eyes searched the dappled darkness. Stealthily the wolf advanced. Hunger had driven him from his snug den. He knew where to find a good meal. Not the mice and birds he had lived on lately, but a hare he had killed and buried in the frozen ground to keep it fresh and safe from crows and ravens. As the dogwolf wound through the trees at an effortless lope, which could carry him as far as 120 miles in a single day, his thic k brow ngrey yellow fur gleamed in the moonlight. He was a fine big dog:owdered horn cured colds, measles, nosebleeds, vomiting, heart weakness. The Japanese claimed it fought fever. Certain people even swore by it as a love potion. Most poachers are poor. So the temptation to earn money by any means, however risky, is very strong. They may work as farmer s for ?00 a year less than they39。d be paid for a single horn. A merchant will sell it to consumers for ?5,000 and upwards. More slides followed. A chimpanzee. Valued at ?,300 on the black market. Much in demand for biomedical research, travelling acts, photography, tourist attractions and the television and film industries. A hyacinth macaw. Going price ?,500 to an avid collector. A peregrine falcon. Bought by Arab falconers for ?,000 each. Seeing the peregrine, Gary fot everything else. His favourite bird! It could swoop at over two hundred miles an hour, spot its prey more than five miles away. Peregrines had once nearly died out in Britain through eating pigeons which had fed on grain sprayed with pesticides ... Bellingham39。s voice broke into the boy39。s reverie. He was talking about Amazon dolphins. These gentle creatures, already threatened by pollution and riverdamming schemes, were being killedtheir eyeballs sold as ornaments and lucky charms in cities such as Rio de Janeiro. Gary grunted disgustedly, and Susan39。s face showed her feelings. The naturalist then mentioned another charming practice: eating bear paws. Considered a delicacy in Japan, Taiwan, Hong Kong and Singapore, the paws of hunted bears are imported from China. The wildlife trade is a worldwide business, w orth billions of pounds. There are strict rules to control that trade. However, some countries don39。t agree to them. Others say they do, but allow crooks and cheats to get away with murderanimal murder. That39。s just one of the reasons why The Eden Mission is a top priority ... Bellingham glanced quickly at his watch. I see time is running out. A few final words. Sea Shepherd39。s programme includes trying to save grey whales and sea otters from oil pollution off California。 manatees from being chopped up by speedboat propellers in Florida39。s waterways。 Amazon dolphins from extermination. We have other tasks too, which I can39。t go into now. The six youngsters sailing with Sea Shepherd, all keen conservationists, will make a valuable contribution. But they39。ll also have to continue their school studies ... Someone in the audience groaned. Ben grinned broadly. Thank you for listening, ladies and gentlemen. Wish us luck! Loud applause. Then he answered lastminute questions from journalists. The audienceclad once more in raincoats, and clutching umbrellasbegan to file out. Parents hugged their children, whom they wouldn39。t see again for twelve months, and gave good advice that would probably be fotten or ignored. There were some tears. Neither Gary39。s nor Susan39。s parents were present. They had already said their goodbyes at home and were glad to be spared e motional partings aboard Sea Shepherd. By now the lecture hall was empty except for six young
