    One spring morning many years ago, I had been searching for gold on southeastern Alaska’s Kupreanof Island, and as I came out of a forest, I froze in my tracks. No more than 20 paces away was a huge Alaskan timber wolf—caught in one of Trapper George’s traps.

Old George had died of a heart attack, so the wolf was lucky I had happened along. Confused and frightened at my approach, the wolf backed away, straining at the trap chain. Then I noticed something else: It was a female, and her teats (乳头) were full of milk. Somewhere there were some hungry pups (狼崽子) waiting for their mother.

From her appearance, I guessed that she had been trapped only a few days. That meant her pups were probably still alive, surely no more than a few miles away. But I suspected that if I tried to release the wolf, she would turn aggressive and try to tear me to pieces.

So I decided to search for her pups instead. After several moments, I spotted paw marks on a trail. I finally spotted the den (狼窝). Wolf pups are shy and cautious, and I didn’t have much hope of luring them outside. But I had to try. So I began imitating the high­-pitched squeak of a mother wolf calling her young. No response. A few moments later, after I tried another call, four tiny pups appeared.

They couldn’t have been more than a few weeks old. I extended my hands, and they tentatively suckled at my fingers. Perhaps hunger had helped overcome their natural fear. Then, I took them to their mother. Possibly picking up the smell of her young, the mother wolf let out a high­-pitched, sad call. The pups raced to her. Within seconds, they were drinking milk at her belly.

The mother wolf was clearly suffering, very weak. I had to find her something to eat. Yet each time I moved in her direction, a growl (怒吼) rumbled in her throat. With her young to protect, she was becoming very cautious. If I could only win her confidence, I thought, it was her only hope.

Over the next few days, I divided my time between prospecting and trying to win the wolf's trust. I talked gently with her, throwing her some meat. Gradually, I kept edging closer — though I was careful to remain beyond the length of her trap chain.

At dusk on the fifth day, I delivered her dinner. Suddenly, I saw a slight wagging of her tail. I moved within the length of her chain. She remained sill. As a towering man, my heart was in my mouth, though. Within her reach, I wrapped my blanket around myself and slowly settled onto the cold ground. It was long before I fell asleep.

The next morning, I slowly placed my hand on the wolf's injured leg. Unexpectedly; she made no threatening move. Then I applied pressure, the trap sprang open, and the wolf pulled free.

My experience told me the wolf would vanish into the woods quickly. But cautiously, she crept toward me and sniffed my hands and arms. This went against everything I'd ever heard about timber wolves. Yet, strangely, it all seemed so natural.
