how did kumalo and jarvis' friendship evolve?

James Jarvis befriends Stephen Kumalo when they meet by chance while Kumalo delivers a letter. Kumalo's son had killed Jarvis but the two form a bond that transcends ill feelings and racial hatred. They see the root causes for Arthur Jarvis's passion as well as his death. Although a conservative white man, James Jarvis eventually devotes himself wholeheartedly to social progress, donating ten thousand dollars to start the Arthur Jarvis Club, donating milk from his estate to help starting children during the drought and arranging for a dam to be built in Ixopo to prevent further droughts.
