In 1977, after two years of a go-slow strike by prisoners in the quarry,
Robben Island finally ends manual labor. Mandela is happy to devote himself more to studying and even gets permission to make a small garden. He orders gardening books and soon improves his yields. Without quarry work, Mandela gains weight, so he starts to take exercising seriously again. Although Mandela is still barred form studying at this point, he has access to other books, mostly novels like
War and Peace and
The Grapes of Wrath.
