From this time onward for twelve years he labored to give his telegraph to mankind; labored in the midst of distressing poverty, the ridicule of acquaintances, and the indifference of the world. Three motherless children were dependent upon him, but he could do little for them. On the corner of Nassau and Beekman Streets, in the newspaper building erected by his brothers,--they were the editors and proprietors of the "New York Observer,"--in the fifth story, a room was assigned to him which he used for studio, sleeping-room, kitchen, and workshop. On one side was his cot, on the other his tools and crude machine. He whittled the models, and then made the moulds and castings. Here, from day to day, the simplest food was brought him, he preparing his own tea. In the year 1835, having been appointed professor of the Literature of the Arts of Design in the New York City University, he took rooms in the third story of the university building. "There," he says, "I immediately commenced, with very limited means, to experiment upon my invention. My first instrument was made up of an old picture or canvas frame fastened to a table; the wheels of an old wooden clock, moved by a weight to carry the paper forward; three wooden drums, upon one of which the paper was wound and passed over the other two; a wooden pendulum suspended to the top piece of the picture or stretching-frame, and vibrating across the paper as it passes over the centre wooden drum; a pencil at the lower end of the pendulum, in contact with the paper; an electro-magnet fastened to a shelf across the picture or stretching-frame, opposite to an armature made fast to the pendulum; a type rule, and type for breaking the circuit, resting on an endless band, composed of carpet-binding, which passed over two wooden rollers, moved by a wooden crank, and carried forward by points projecting from the bottom of the rule downward into the carpet-binding; a lever, with a small weight on the upper side; and a tooth, projecting downward at one end, operated on by the type; and a metallic fork, also projecting downward over two mercury-cups; and a short circuit of wire, embracing the helices of the electro-magnet connected with the positive and negative poles of the battery, and terminating in the mercury-cups." Morse was now so poor that he bought his food in small quantities from some grocery, and prepared it himself. He says, "To conceal from my friends the stinted manner in which I lived, I was in the habit of bringing my food to my room in the evenings, and this was my mode of life for many years."
