Stanley was behind Magnet. He didn't know what day of the week it was, let alone the date. It could have been July 8, but how would Zigzag know?

Then a little while later he cut into the breakfast line, just in front of Squid. Squid told him to go to the end of the line. "Hey, it's my birthday," Zigzag said, staying where he was.

"It's not your birthday," said Magnet, who was standing behind Squid.

Forty-six days. It felt more like a thousand. He didn't dig a hole that first day, and he hadn't dug one yet today. That meant he'd dug forty-four holes -- if it really was July 8.

"Forty-six days," said Zero.

The next day was Zigzag's birthday. Or so he said. Zigzag lay in his cot as everyone headed outside. "I get to sleep in, because it's my birthday."

"Is too," said Zigzag. "July 8."

He tried to figure out how long he'd been at Camp Green Lake, if indeed it was July 8. "I came here on May 24," he said aloud. "So that means I've been here…"

Stanley was still trying to remember how many days there were in May and June. He looked at Zero. He'd learned not to doubt him when it came to math.

"Can I have an extra carton of juice?" Zigzag asked Mr. Sir. "It's my birthday."

Of course it helped that Zero dug some of his hole for him each day, but that wasn't as great as everyone thought it was. He always felt awkward while Zero was digging his hole, unsure of what to do with himself. Usually he stood around awhile, before sitting off by himself on the hard ground, with the sun beating down on him.

Mr. Sir was no longer depriving him of water. After having to get by on less water for a week or so, Stanley now felt like he had all the water he could want.

To everyone's surprise, Mr. Sir gave it to him.

But that really wasn't true, and he knew it. He was a lot stronger than when he first arrived. His body had adjusted somewhat to the heat and harsh conditions.

Stanley dug his shovel into the dirt. Hole number 45. "The forty-fifth hole is the hardest," he said to himself.

It was better than digging.

But not a lot better.

When the sun came up a couple of hours later, Stanley looked for "the thumb of God." The mountains were little more than dark shadows on the horizon.

Zero took his turn before the lunch break. Stanley climbed out of his hole, and Zero climbed down into it.

He thought he could make out a spot where the top of one mountain seemed to jut upward, but it didn't seem very impressive. A short time later the mountains were no longer visible, hidden behind the glare of the sun, reflecting off the dirty air.

"He's not my slave," said Stanley. "We have a deal, that's all."

"A good deal for you," said Zigzag.

"Hey, Caveman," said Zigzag. "You should get a whip. Then if your slave doesn't dig fast enough, you can crack it across his back."

It was possible, he realized, that he was somewhere near where Kate Barlow had robbed his great-grandfather. If that was really her lipstick tube he'd found, then she must have lived somewhere around here.

"Well, what about me?" asked Armpit. "I like to dig holes, too. Can I dig for you, Caveman, after Zero's finished?"

"It was Zero's idea, not mine."

"Don't you know, Zig?" said X-Ray, coming over. "Caveman's doing Zero a big favor. Zero likes to dig holes."

"He sure is a nice guy to let Zero dig his hole for him," said Squid.

When Mr. Pendanski arrived with water and lunch, Zigzag offered Stanley his place in line. "Since you're so much better than me."

Stanley hesitated, then moved to the front of the line.

Zigzag kept at it. "Come on, Caveman. Be a pal. Let me dig your hole."

"No, it's not okay," said X-Ray. "Get up here."

"No," said Stanley.

"You're insulting him, Zig," said X-Ray. "Why should Caveman take your place, when he deserves to be at the very front? He's better than all of us. Aren't you, Caveman?"

"Sure you are," said X-Ray. "Now come to the front of the line where you belong."

"No, I want to," said Zigzag. "It's my birthday."

The other boys laughed.

"That's okay," said Stanley.

Stanley tried his best to ignore them.

Stanley smiled, as if it were all a big joke.

"Well, this is a first," Mr. Pendanski said, coming around the side of the truck. He filled Stanley's canteen and handed him a sack lunch.

Stanley was glad to get away. He sat down between his hole and Zero's. He was glad that he'd be digging his own hole for the rest of the day. Maybe the other boys would leave him alone. Maybe he shouldn't let Zero dig his hole for him anymore. But he needed to save his energy to be a good teacher.

Stanley remained where he was. "I didn't say I was bet --"

"I'll give you my cookie if you let me dig your hole," said Zigzag.

He bit into his sandwich, which contained some kind of meat-and-cheese mixture that came in a can. Just about everything at Green Lake came in a can. The supply truck came once a month.

"Here, take my cookie," said Zigzag, holding it out for him.

Zigzag kept after him. He shoved Stanley and said, "Quit pushing!"

Stanley pushed it away.

Stanley took a step backward, carefully avoiding Zero's hole.

"Why should he?" snapped X-Ray. "Caveman's bigger. He can take care of himself."

Zigzag pushed him back. "Don't push me!"

"Leave me alone," said Stanley.

He glanced up to see Zigzag and Squid walking toward him.

"I didn't…" Stanley got to his feet. He looked around. Mr. Pendanski was filling Zero's canteen.

"C'mon, take my cookie," said Zigzag, sticking it in his face.

Zigzag pushed him again. "I said, 'Don't push me.'"

"Please eat my cookie," said Zigzag, holding it under Stanley's nose.

Squid laughed.

"No, thanks," said Stanley.

Squid laughed.

"Lay off," said Armpit, as he, Magnet, and X-Ray joined them.

Stanley stared at Mr. Pendanski in astonishment.

The side of Stanley's face was pressed flat against the dirt. He tried to protect himself, but Zigzag's fists slammed off his arms and pounded his face into the ground.

Stanley was glad to see Mr. Pendanski coming toward them, along with Zero.

"That's enough!" Mr. Pendanski yelled.

The collar ripped and Stanley fell backward onto the dirt.

Stanley made a feeble attempt to punch Zigzag, then he felt a flurry of fists against his head and neck. Zigzag had hold of his collar with one hand and was hitting him with the other.

"I don't want any trouble," Stanley said.

"Teach the bully a lesson," said Mr. Pendanski.

Zigzag pushed him hard. "Eat my cookie," he said.

"I saw what was going on," Mr. Pendanski said. He turned to Stanley. "Go ahead, Stanley," he said. "Hit him back. You're bigger."

It wasn't enough for Zigzag. He jumped on top of Stanley.

"Hi, Mom," said Armpit. "We were just fooling around."

"Stop!" shouted Mr. Pendanski.

Zigzag hit Stanley on the shoulder with his open hand. "Teach me a lesson," he challenged.

Zero kept squeezing.

"Nothing. It wasn't a riot."

"Ziggy was beating up the Caveman," said Armpit. "Then Zero started choking Zigzag, and I had to pull Zero off of Zigzag. It was all over before Mom fired his gun."

Armpit charged into them, freeing Zigzag from Zero's choke hold. The three boys fell to the ground in different directions.

Mr. Pendanski fired his pistol into the air.

"You're going to kill him!" shouted Mr. Pendanski.

The other counselors came running from the office, the tents, or out on the lake. They had their guns drawn, but holstered them when they saw the trouble was over.

The Warden walked over from her cabin.

"There was a riot," Mr. Pendanski told her. "Zero almost strangled Ricky."

Zigzag made a gagging sound, as he desperately tried to pry Zero's arm off of him.

Then, suddenly, Zigzag was off of him. Stanley managed to look up, and he saw that Zero had his arm around Zigzag's long neck.

All he could do was wait for it to be over.

The Warden looked at Zigzag, who was still stretching and massaging his neck. Then she turned her attention to Stanley, who was obviously in the worst condition. "What happened to you?"

"Excuse me?" said the Warden.

The Warden looked from Squid to Stanley to Zero.

"Isn't it more important for him to learn to read?" Stanley asked. "Doesn't that build character more than digging holes?"

"I see," the Warden said. She turned to Zigzag. "What's the matter? Didn't you get a puppy for your birthday?"

"Zero's been digging part of Caveman's hole every day," said Squid.

"Yeah," said Zigzag. "Like X-Ray said. Working so hard in the hot sun, while Caveman just sits around doing nothing. My blood boiled."

"They just got a little hot, that's all," said X-Ray. "You know how it is. In the sun all day. People get hot, right? But everything's cool now."

"Excuse me?"

"Is that what happened, Zigzag?" asked the Warden.

"Excuse me?" said the Warden. "Caveman digs his holes, just like everyone else."

"I'm teaching him to read and write," said Stanley. "It's sort of a trade. The hole still gets dug, so what does it matter who digs it?"

"Zig's just a little hot," said X-Ray. "Out in the sun all day. You know how it is. The blood starts to boil."

Zigzag shrugged. "Sometimes."

The Warden turned to Zero. "Well, Zero, what have you learned so far?"

"The 'at' sound," said Zero.

Stanley hadn't taught him the "f" sound yet.

"Tell me what you learned yesterday," said the Warden. "Surely you can remember that."

"He likes to dig holes," said Mr. Pendanski.

Zero said nothing.

Mr. Pendanski clapped his hands. "Bravo! Bravo! The boy's a genius!"

"Have you just been digging Caveman's hole for nothing?" the Warden asked him.

Zero glanced around uneasily.

"That's his character," said the Warden. "What about your character?"

"The 'at' sound," repeated the Warden. "Well then, tell me, what does c -- a -- t spell?"

"Cat," Zero said.

Stanley knew he knew the answer. Zero just didn't like answering questions.

Mr. Pendanski laughed. He picked up a shovel and said, "You might as well try to teach this shovel to read! It's got more brains than Zero."

Stanley raised and lowered one shoulder.

Zero thought a moment.

Zero said nothing.

"Eff," Zero whispered. "Eff -- at. Fat."

"F -- a -- t?" asked the Warden.

Zero concentrated hard, then said, "Chat."

All the counselors laughed.

"Why can't I dig my own hole, but still teach Zero to read?" he asked. "What's wrong with that?"

"I guess not," Stanley mumbled, although he knew they weren't digging just to learn a lesson. She was looking for something, something that belonged to Kissin' Kate Barlow.

"I'm not digging another hole," said Zero.

Stanley didn't know why Mr. Pendanski seemed to have it in for Zero. If Mr. Pendanski only thought about it, he'd realize it was very logical for Zero to think that the letter "h" made the "ch" sound.

Stanley hadn't taught him the "h" sound either.

"Okay, from now on, I don't want anyone digging anyone else's hole," said the Warden. "And no more reading lessons."

"Good," said the Warden. She turned to Stanley. "You know why you're digging holes? Because it's good for you. It teaches you a lesson. If Zero digs your hole for you, then you're not learning your lesson, are you?"

"How about h -- a -- t?" asked the Warden.

"He's a genius, all right!" said Mr. Pendanski. "He's so stupid, he doesn't even know he's stupid."

"I'm not digging another hole," said Zero.

Then he swung it like a baseball bat.

The counselors all drew their guns.

Zero took the shovel.

Mr. Pendanski handed him the shovel. "Here, take it, Zero. It's all you'll ever be good for."

"It causes him stress," said Mr. Pendanski. "I know you mean well, Stanley, but face it. Zero's too stupid to learn to read. That's what makes his blood boil. Not the hot sun."

The metal blade smashed across Mr. Pendanski's face. His knees crumpled beneath him. He was unconscious before he hit the ground.

Zero held the shovel out in front of him, as if he were going to try to bat away the bullets. "I hate digging holes," he said. Then he slowly backed away.

"I'll tell you what's wrong with that," the Warden said. "It leads to trouble. Zero almost killed Zigzag."

Zero kept backing up, out past the cluster of holes the boys had been digging, then farther and farther out onto the lake.

"Don't shoot him," said the Warden. "He can't go anywhere. The last thing we need is an investigation."

The Warden ordered the counselors to take turns guarding the shower room and Wreck Room, all day and all night. They were not to let Zero drink any water. When he returned, he was to be brought directly to her.

Stanley noticed Zero's canteen lying on the ground near his hole.

She examined her fingernails and said, "It's almost time for me to paint my nails again."

"He's going to have to come back for water," the Warden said.

Stanley looked out toward Zero, but he had disappeared into the haze.

Before she left, she told the six remaining members of Group D that she still expected seven holes.

A couple of the counselors helped Mr. Pendanski to his feet and into the truck.
