London creates suspense in the scene in which buck pulls the thousand-pound load by narrating the events and focusing on the expressions of the crowd gathered at the event.

Explanation:

In the call of the wild London narrates with detail the situation in which Buck pulls the thousand-pound load. He follows the behavior of the dog and the reaction of the crowd. He also provides detail in the high level of tension and stress lived by the crowd when they watch the dog pull the load. However, the element that makes the narration so dramatic is the events he focuses on, instead of any high level descriptive, or figurative skill.
