From a consideration of these facts, and with his usual tendency to upset traditional observances, Edison conceived the bold idea of constructing gigantic rolls which, by the force of momentum, would be capable of crushing individual rocks of vastly greater size than ever before attempted.

I myself think of Edison side by side with Christopher Columbus, and I guess the high chair he sets on up in my mind, with his lap full of his marvellous discoveries, is a little higher than Columbuses high chair. Oh, how congenial the Ragah of Kahurthalia would be! How I wish we could have visited together! But it wuzn't to be, for Josiah said that he'd gone the night before, so we wended on.

Edison, the boy's father, had built a wooden tower that permitted a beautiful view of the town, River St. Clair and Lake Huron; one could see miles around in Michigan and over into Canada. Mr. Edison charged ten cents a head to go up and get the view on top of this tower. Very few people came, so the tower was not a great success.

Since that date the industry has developed very rapidly, and at the present time all of the principal American manufacturers of motion pictures are paying a royalty to Edison under his basic patents.

"Just as young Ben Franklin, on arriving in New York City from Boston, looked for a job in a printing office, the youthful modern inventor applied for work in a telegraph office there. As there was no vacancy and he needed the rest of his borrowed dollar for meals, Edison found lodging in the battery room of the Gold Indicator Company.

Edison tells the story in a similar manner, but insists that it was he who saved the situation. "I managed to say that I would work the apparatus, and Mr. Adams would make the explanations. Adams was so embarrassed that he fell over an ottoman. The girls tittered, and this increased his embarrassment until he couldn't say a word.

The reporters are never away from the laboratory very long; for if they have no actual mission of inquiry, there is always the chance of a good story being secured offhand; and the easy, inveterate good-nature of Edison toward reporters is proverbial in the craft.

They were situated on Goerck Street, New York, north of Grand Street, on the east side of the city, and there, very soon after, was established the first Edison dynamo-manufacturing establishment, known for many years as the Edison Machine Works. The same night Insull made his first visit to Menlo Park.

The most brilliant work of Darwin, Kelvin or Edison in no wise alters the fact that there are more things in heaven and earth than are revealed by their microscopes or decomposed in their crucibles. Mental science, and above all moral or ethical science, have a claim to be heard as well as physics.

After thorough investigation of the magnetic qualities of different kinds of iron, Edison began to make a study of winding the cores, first determining the electromotive force generated per turn of wire at various speeds in fields of different intensities.
