Sample text

By this time, Aleck and Mabel were in love. Aleck hoped to marry Mabel. Aleck kept working on the telegraph. But he also had a new idea. 34 35 Aleck wanted to make a machine that let people talk over wires. He knew that air changes when sounds move through it. Vibrations make waves of sound in the air. Maybe sound waves could also change an electrical current. If they could, spoken words could be sent over a wire. Aleck and Watson began to work on a talking machine, too. For months, they tried connecting wires in different ways.

33 Aleck and Watson worked at night in the machine-shop attic. Some nights, they did not sleep. Mabel Hubbard joked about Aleck’s late nights working in the shop. One day she drew a picture of him with an owl’s head! Owls stayed awake at night, too. By this time, Aleck and Mabel were in love. Aleck hoped to marry Mabel. Aleck kept working on the telegraph. But he also had a new idea. 34 35 Aleck wanted to make a machine that let people talk over wires. He knew that air changes when sounds move through it.

But he faced several problems. He did not have money to buy supplies for his project. Mr. Sanders and Mr. Hubbard agreed to help him. 32 Aleck had good ideas about how to make things. But he was not so good at putting them together. He paid men at a machine shop. They would build the things he needed. Aleck thought Thomas Watson was the best mechanic in the shop. The two men decided to work together. 33 Aleck and Watson worked at night in the machine-shop attic. Some nights, they did not sleep.
