My family moved from Toowoomba, Canada to London in 1950. My mother was in great pain from the 1950s epidemic of polio （小儿麻痹症）. She wished to visit specialists in London. The day before we boarded the ship, Father bade a tender farewell to his five-year-old " friend" at the dock（码头）， an Australian cattle dog, Spider, who was loved by us all. Father' s friend Sandy was to be his guardian while we were overseas.
Six weeks later, a letter arrived from Sandy, giving my father the news that Spider had run away just two weeks after we had sailed. I will always remember my father' s face crumbling and his eyes glistening as he read the letter. We tried to comfort him, knowing in our hearts how useless this was. Sandy has advertised constantly on ABC radio and other local newspapers. Despite some " sightings" in the dock at first, the dog was never found later. It seems Spider decided to search for us elsewhere.
We sailed back two years later and re-established our home in Toowoomba. My father immediately began his own searching for Spider. Several months passed but there was still no news concerning Spider. The dog was gone, possibly shot or dead from starvation or exhaustion.
One cold morning eight months after our return, my father had a call from an old lady who said she was putting food out " for a very old dog" . In the night the food disappeared. This had been going on for a few weeks. That was enough for my father to interrupt my homework and we set off immediately. When we arrived at the old lady' s house, she invited us into an old bush. Sadly, she then told us that the " dingo dog" hadn' t been around for a few days. My father had a strange look in his eye. He put two fingers to his lips and did his special whistle（口哨） for Spider.
