Answer:
In chapter nine, Jack tries to tempt the rest of Ralph's group to join the hunters by offering them food, safety, and fun, a potent mix that the boys find hard to resist. When Ralph and Piggy arrive at Jack's site, they see piles of roasted meat and coconuts to eat. Jack sits on a log that is like a throne, painted like an idol, surrounded by heaps of food. When he demands to be brought a drink, it is brought to him. So the answer is he wants other boys to join his tribe.
