As successful as these stories were, he went on to write the line of books known as Dr. Seuss which sky-rocketed his fame. The Dr. Seuss books contained small, short choppy sentences with easy words so children could understand them. He often used these books to present worldly problems, but on a level to which children could relate. .
The Lorax is a story inside a story. The old Once-ler is telling a young boy his account of where the Lorax had gone. At the Street of the Lifted Lorax, the Once-ler found some Truffula trees. The Once-ler had been searching for these trees because of their bright colors and the silky feel they had to them. He chopped one down and made a thneed from it which can be used to make a sock, pillowcase, or anything that was needed. All of a sudden, the Lorax appeared. He was very upset because the Once-ler was chopping down the Truffula trees to make a useless thneed. The Lorax was very angry when a man bought a thneed, so he left. The Once-ler then called his family, and they moved to the Street of the Lifted Lorax to help bigger his business. The Once-ler family chopped tree after tree, and once again the Lorax showed up. He spoke for the trees and brown Bar-ba-loots who lived off the trees. They now had to move away or else they would die. The Once-ler didn't care though, he just kept making his business bigger and bigger. A few days passed, and the Lorax showed up again. This time he was speaking for the Swamee-Swans. They had to leave, too, because the smoke from the thread factory was making them sick. Even this did not stop the Once-ler. He kept his business growing. Later on, the Lorax showed up once again speaking for the Humming-fish. They had to relocate also, because of the glop from the thneed machine that was being put into the pond. .
While the Once-ler and Lorax were talking, the very last Truffula tree was chopped down. The Lorax said nothing. He just left the Once-ler and never looked back.
