Sams immediate companion is Gus, his pet raccoon, which lives with him in the city. He gathers supplies at a local store, hops on a bus, and heads down the 401 with Gus to what he calls the Laurentian Mountains of Quebec. In actuality he ends up in the picturesque town of Knowlton, Quebec, southeast of Montreal, in the Notre Dame Mountains Range of the Appalachians. Here he finds the perfect mountain stream and pond location to build a home in an old dead tree. He begins his longplanned algae experiments and proves his ability as a solitary young Thoreau living off the land and communing fully with nature.Sam wants badly not to have to feel needful of the urban and modern world, however, the sight of a falcon overhead inspires his curiosity about falconry. He journeys back to Knowlton and to the local library, where the librarian and birdenthusiast Miss Turner Tudi Wiggins supplies him with books on falconry. He steals a chick from a local falcons nest. It, whom he names Frightful, becomes his new best friend and food supplier, after he teaches it to hunt. ........
