Final answer:
Paul chose to go for a hike in the wilderness to find peace away from the city.
Step-by-step explanation:
When Paul was tired of the city, he went for a hike in the wilderness. This hike led him to Toby Creek, where he found solace in the natural beauty and the sound of a sparkling cataract (waterfall). The noise of the falling water was salutary, helping him wash away any animosity that had built up during the week. His actions reflect a desire for simplicity and a connection with nature, reminiscent of the philosophies of Thoreau and the tranquility sought by those who are overwhelmed by urban life.
