Edison, His Life and Inventions [41]
time, than the carrying out of experiments outlined in the books. The foundations were being laid for the remarkable chemical knowledge that later on grappled successfully with so many knotty problems in the realm of chemistry; notably with the incandescent lamp and the storage battery. Of one incident in his chemical experiments he tells the following story: "I had read in a scientific paper the method of making nitroglycerine, and was so fired by the wonderful properties it was said to possess, that I determined to make some of the compound. We tested what we considered a very small quantity, but this produced such terrible and unexpected results that we became alarmed, the fact dawning upon us that we had a very large white elephant in our possession. At 6 A.M. I put the explosive into a sarsaparilla bottle, tied a string to it, wrapped it in a paper, and gently let it down into the sewer, corner of State and Washington Streets." The associate in this was a man whom he had found endeavoring to make electrical apparatus for sleight-of-hand performances.
In the Boston telegraph office at that time, as perhaps at others, there were operators studying to en- ter college; possibly some were already in attendance at Harvard University. This condition was not unusual at one time; the first electrical engineer graduated from Columbia University, New York, followed up his studies while a night operator, and came out brilliantly at the head of his class. Edison says of these scholars that they paraded their knowledge rather freely, and that it was his delight to go to the second-hand book stores on Cornhill and study up questions which he could spring upon them when he got an occasion. With those engaged on night duty he got midnight lunch from an old Irishman called "the Cake Man," who appeared regularly with his wares at 12 midnight. "The office was on the ground floor, and had been a restaurant previous to its occupation by the Western Union Telegraph Company. It was literally loaded with cockroaches, which lived between the wall and the board running around the room at the floor, and which came after the lunch. These were such a bother on my table that I pasted two strips of tinfoil on the wall at my desk, connecting one piece to the positive pole of the big battery supplying current to the wires and the negative pole to the other strip. The cockroaches moving up on the wall would pass over the strips. The moment they got their legs across both strips there was a flash of light and the cockroaches went into gas. This automatic electrocuting device attracted so much attention, and got half a column in an evening paper, that the manager made me stop it." The reader will remember that a similar plan of campaign against rats was carried out by Edison while in the West.
About this time Edison had a narrow escape from injury that might easily have shortened his career, and he seems to have provoked the trouble more or less innocently by using a little elementary chemistry. "After being in Boston several months," he says, "working New York wire No. 1, I was requested to work the press wire, called the `milk route,' as there were so many towns on it taking press simultaneously. New York office had reported great delays on the wire, due to operators constantly interrupting, or `breaking,' as it was called, to have words repeated which they had failed to get; and New York claimed that Boston was one of the worst offenders. It was a rather hard position for me, for if I took the report without breaking, it would prove the previous Boston operator incompetent. The results made the operator have some hard feelings against me. He was put back on the wire, and did much better after that. It seems that the office boy was down on this man. One night he asked me if I could tell him how to fix a key so that it would not `break,' even if the circuit-breaker was open, and also so that it could not be easily detected. I told him to jab a penful of ink on the platinum points, as there was sugar enough to make it sufficiently thick to hold up
