 was made that equalled about 30S,0O(
 candle power To more readily compre-
 bend the intensity of light, let us say
 it would be equal to about 160 of tht
 arc lamps used for lighting Main street
 This produced heat of between 4,00C
 and 5000 degrees Fahrenheit.
 We burned hole with this appara-
 tus inches in diameter and 26 inches
 deep in about four hours. Into this hole
 dynamite was placed and the mass
 broken up into small pieces, which 1 could readily removed, and the work
 of refining the furnace commenced
 much sooner than if drills had been
 used to make holes for the dynamite.
 "A curious thing about the work, and 1 perhaps the most interesting feature
 was the fact that nearly everybody
 who looked at the arc, even for a very
 few minutes was affected with inf1am-
 nation in their eyes of very severe l character, the only exceptions being | two men who wore plain white glass ! spectacles, and they suffered no incon- | venience whatever, although one of 1 them looked at the light great deal. I
 was effected worse than any of the oth- CTS, because stood within ten feet of
 the arc and looked a it more than any
 one else, After the first trial rode
 home on ri1y wheel. and before reaching
 home was nearly blind and in terribly
 abony I consulted a physician imme diately, and he was completely puzzled to account for the inflammation, My eyes were bloodshot and the lids SO in
 flammed that the eyes were completely closed. l kept my eyes bandaged and
 treated them with an eye wash, alter
 mated with witch hazel baths, but suf- fered great deal for four days. Tn ad- dition to the trouble I had with my eyes, the skin on my face all peeled off, except where protected by the hair. Where my face was shaded by my hat the skin did not peel so badly but came off quite badly, though.
 The doctor said he never had heard of anything like it. and did not know what could have caused the trouble un- less it was that the light developed was too intense and of too great volume for the optical nerves to accommodate it. He thinks, as do several other per sons. that this light was some sort of an "X" ray because of the penetrating power He was entirely at Joss to &C., count for the peeling of my face.
 "The next morning ten or twelve of the foremen and employees complained of similar trouble. In fact, every one who looked at the arc except the two who wore glasses, were more or less se- verely affected. Some were laid up totally blind, for a day or two. Others T 1,,1,+ |. rt.s eral who came to work the next morn ing worked under difficulty on account of the pain and inflammation in their eyes
 "A few days ago we were starting up another furnace that had been banked and some of the iron had chilled around the iron notch. l used the same appara- 1 tus to burn a hole through to let the ! iron out but this time I made a shield | of asbestos and cut a hole for the car- bon to go through. The shield was in- tended to reflect the light downward, instead of allowing 1t to radiate directly out and toward the person operating the carbon It required a man at the handle all the time, for if the arc should get too long 1t would break and ' the carbon would have to be brought nto contact with the iron before 1t would form another It worked fastest 1t about a three-inch arc, and to keep | t there required constant attention. I also made an asbestos mask to fit over ny face and fitted it with pair of white glass stonecutter's goggles as I wanted to get the benefit of the protec- ion had by the men who wore glasses when looking at the. first trial
 This time I did not feel the heat so much as the first time and did not suf- CT so much from infamma ton in my yes, although there was a little inflam- nation in them.
 1T do not think the heat is what af- ected us think it was the light. The ast time, of course, we proflted by our ormer experiences and nobody at empted to get within sight of the arc nless they had business there. There vas also a disagreeable gas which eemed to be general at the arc. It was
 kind of a sulphurous smelling gas, ut was not powerful enoueh to hncor'7a 
 "The last time I used the apparatus l i'd not care to make any experiments, ut only got hole started through 'hich the iron could run. After the 1olten iron once got started it would apidly finish the work and enlarge the ole to it's normal size without any as- istance, but the thing to do was to get le iron started. We formerly used a etroeum blew pipe for this work The bjection to the blow pipe is that it i iakes such a large hole it g'ves no $ me to get out of the way before the ] on rushes out.
 Aside from the inconvenience suf- cred the work is very interesting from
 scientific view
 What do you think would be the ef-
