What page in the novel Lord of the Flies do the hunters attack the wounded pig, and Ralph drives his spear into her as she squeals?

In Chapter 8, Jack and his hunters find a group of pigs laying under some trees. Jack spots a huge, black female pig who is nursing her young. The group surrounds her and take aim from about ten yards away. As the hunters throw their spears, two stick into her side, and she burst through the line of boys, escaping into the forest. Eventually, the boys track the sow through the forest, and she hides in the brush. Injured, the pig staggers into an open space where she falls down. When she falls the hunters "hurl themselves at her" and begin stabbing her brutally with their spears. On page 135, while Jack is on top of the sow, Roger sticks his spear up the pig's behind and pushes with all his weight into the spear. Jack slits the sow's throat, effectively killing the pig. Golding describes this brutal scene to illustrate the extent in which the boys have descended into savagery.
