Why did Professor Myers talk so much? At least it was better than the meditation. But only slightly. Olly did try to pay attention. He really did. But it was not very interesting. Who cared that much about trees? Okay, professor Myers did. And Jaemin. He had been right about the whip grafting thing, which was cool.

Olly didn't really understand the concept. He stared blankly at Professor Myers. They were going to cut off the branches of one tree and glue it to the roots of another? No, that didn't make sense. But it had something to do with combining the two things somehow. Olly didn't understand how, that was the problem. He raised his hand. "How exactly do we do that? Do we just...place them next to each other?" That probably would not do anything. But he didn't understand how they could combine two plants.

He also had to actually answer the question Professor Myers asked. "Then one tree could give nitrogen and anti-pollutants." And that would be cool, right?
