"Roger gathered a handful of stones and began to throw them. Yet there was a space round Henry, perhaps six yards in diameter, into which he dare not throw. Here, invisible yet strong, was the taboo of the old life. Round the squatting child was the protection of parents and school and policemen and the law."
This quote is from Chapter four and demonstrates Rogers cruelty towards the littluns. Rogers hostility towards the litlluns shows the decline on society into savagery.
