Three years later he moved to Menlo Park.
This was twenty-four miles from New York.
It was not a pleasant place, but he hoped to work there in quiet.
He had so many visitors that he could not work.
He said, "I think I shall fix a wire to my gate, and connect it with a battery so that it will knock everybody over that touches it."
But he was really kind.
He would smile pleasantly, and explain patiently to anyone who wished to know about his inventions.
At Menlo Park he built a great laboratory.
This was filled with batteries and machinery.
Here all the world came to see his wonderful talking machine.
