The United Stales, un like the government of Europe, has made little effort to collect statistics upon tills subject, but those that have been collected Indicate that alnv.st Jl the. accidents from the, use of high ex ' plosives are duo to carelessness In han dling. The carelemness of men who handle dy namite Is proverbial. "As careless as a powder monkey' Is a phrase that doscrites a well established condition.

He had been repeatedly warned that smoking; was con trary to orders and the officer beckoned t4 him. Before the Kaffir could rise there won an explosion of "5,000 pounds of high explosives and Ii5,ou0 pounds of gunpowder. A spark from the pipe had Ignited some powdr which had leaked out through a crack In the Iwuse. Innpector Wolf of the bureau of combus tibles soys that all the recent acci dents In New York and Its vicinity were undoubtedly due not to the fact that those In-authority did not prepare rules provid ing proper precautions, but to the careless ness of workmen. "There are no doubt placea In which high explosives are stored In amounts In excess of that allowed by the law," Inspector Wolf continued. "I have been spending days and nights In Investigating places In which such, violations have been reported. "Hut so long as building operations con tinue In their present magnitude, and the demands for excavations are as great, the law, as It at present exists, Is Inadequate, specially Is this true during the winter months, when a larger quantity of the ex ploitive is required In order that 1t may be thawed for use. Frozen dynamite, you know. Is Ineffective, and, being practically nonexploslve Is much less dangerous to have, In bulk In the city. In spite of the Immense quantities of dynamite that has been used In re cent' years. New Turk has been com paratively free from disastrous accidents. The most serious of all was tliat on Tark avonue near the Murray III1I hotel In Janu ary, lS9i during the construction of the subway. This, it Is believed, was caused find some new and startling trait. As this discovery Is generally mude at the cost of an explosion that wrecks the building, Its value Is a problem that Is left for the Investigator who follows. One of the earlier Du Ponts while show ing some army officers through the plant In Delaware was killed In one of tlio retort rooms. A man who had been In the room but a few minutes before the explosion raid thut the muss of nitroglycerine was boiling and bubbling the way that, ac cording to all precedents. It should. But something happened In a minute, or per haps a second, that brought Instant death and destruction. Whllo a Are which destroyed a pier In Hoboken In May, 1901, was In progress a carload of dynumlte was pulled out, a mass of flames. It was rushed, blazing fiercely back Into tho yards, water wa turned on, and flames were extinguished. There was no explosion. Yet a spark from a passing locomotive falling into a brush heup against a magazine at the Laguna Pain, Ariz., caused an explosion In which 1,000 pounds of powder and dynamite were exploded, caus ing great damage to property and serious Injury to many persons. A powder wagon containing 3,000 pounds of dynamite was struck by a passenger train at a crossing near St. Louis, Mo. The wagon was demolished, the mule at , tached to It was killed and dynamite was scattered all over the right-of-way. But there was no explosion. , At Jelllco, Tenn., fifteen persons were said to have been killed and many Injured by tho explosion of a car of dynamite. An Investigation showed that the car had been shot Into by a person using one of the powdes cards ns a target. Shooting Into dynamite seems to be ono of the sure and certain ways of causing an explosion. The records are full of ac counts of catastrophes caused by Ignorant people shooting at the magazines. The explosion of three cars of dynamite at Johannesburg, South Africa, In which a score of peoplo were killed, was laid to a stray bullet. Boys shooting Into old buildings that were formerly used fur storing explosives have on several occa sions been credited with lessening trie tramrj population. The desire of all experimenters In high explosives Is to make one that shall have came unduly high, and for It to drop on the hot Iron pipe. Well, nitro glycerine that drops from the height of a foot onto a hot metallic surface will ex plodeyou can try this yourself by drop ping a little on the top of a stove and as a result a good many thaw houses come to a sudden and unexpected end. "The method which Is employed here Is to have a small building heated by steam or hot pipes. The pipes or radiators are placed at one end of the room and en cased In such a manner that It Is not possi ble for any one to put dynamite where It can touch them or where any drop of nitro glycerine which might exude from the cartridges would come in contact with the pipes or radiators and so possibly cause an explosion. "One of the most remarkable Incidents In the thawing line Is reported in an Hngllsh blue book of 1905. A farmhand at Wheatley, near St. Paul, Minn., drank a small bottle of nitroglycerine on a wager. He was found afterward by the roadside frozen to death. The corpse was placed In an out-bulldlng near a stove, In order that It might be thawed, when the nltroglyi erlne exploded and wrecked the building. "Dynamiters hear some strange stories. One that was told mes happening in Lus ted, Ore., was of a man who In trying to kill a dog fastened him to a tree, tied a dynamite cartridge to the dog's tall and ran. "But the dog broke loose and followed him. The man took refuge in the houso, and opened up a fusillade of household utensils to drive the beast away. The unl mal retreated beneath the house, where the cartridge exploded, doing nlmost as much damage. t tle inun as to the dog. "But nitroglycerin!) is a queer stuff, nny wuy. About the only thing that I have learned for sure about It after being around the works where It la made is that It blows out the walls of buildings when It explodes, while the powder blows off the roof. . "For that reason you wl)l find around a nitroglycerine house an earthwork that makes It look like a small fortress. When ever there Is an explosion '"sou can look over the walls of this rampart and about all that yau can see of what wus there before Is a lot of kindling wood piled up somewhat recklesslly In the center of the space. "People who work with the dangerous stuff seem to get mighty careless In Its use. I remember of a gang of workmen over In New Jersey who were playing cards at a table where one of the legs was too short. "Ono of the fellows thought to remedy this by putting a piece of dynamite, which was the most convenient tning ai nana, under It. It was all light until tho dis cussion became heated and they began to pound on the table. When thu smoke cleared away there were several missing arms und leys and other portions of anatomy. "Grumplness Is the worst fault of these workers. Whenever a man gets grumpy the best thing that can happen to him Is to get fired. Just out of pure cussedness you will find thut fellow beginning to bring knives and pieces of metal Into the works In strict violation of orders. Just na likely us not you will find him hiding about him self n plre and matches and at noontlms ho will be out smoking under a tree talk ing to himself. "I don't know Just why this Is. It la certainly not caused by nervous strain, for these men working every day In the greatest danger, apparently have no Idea of fear as the ordinary person understands It. On the other hand, a man who Is dally exposed to peril In his work In the factory will go all to plepes over some perfeotly absurd thing outside. "This lost winter on a ferryboat crossing the Delaware were a number of people em ployed In the nitroglycerine works. The bn.it got stuck In the Ice and most of the passengers got off without much remon strance and walked to the shore. But every one of those nitroglycerine work men was afraid to leave the boat, and they spent part of the night there rather than take the risk of going over the Ice. "A big follow who carries cartridges of plant gelatine down into submarine works, w hich most anybody would consider as the most dangerous employment in the world, was down at one of the nitroglycerine factories. He wanted to see, he said, how the stuff that ho handled was made. "After ho hnd been throunh the plant he went up to one of tho workmen and said: " 'How much do you get a day hereT " " 'Two dollars and a half," was the reply. " 'Why, I wouldn't stay around here an other day for $250,000,' said the big fel low, and he went happily back to his gelatine toting." ress of Application in the Field of Electricity Prog, Electrical Trains tn Jlew York. HE substitution of electric motors for steam locomotives on the Har lem division of the New York Central railroad became a fixed fact last week. At present the electric division of thirteen mites extends from the Grand Central station to Wake field. All passenger trains, 152 In cumber, discard locomotives at Wakefield and are drawn to and from the station by electric motors. Eventually the electric zone will by the making of primers In the thawing Kreat power and also be safe for those eltelld thirty-five miles on the Hudson house, combined with a fire In the waste paper from the wrappers around the ex plosives." Mr. Wolf said that there had been no official statistics preserved of the accidents In the city and taelr causes, and that the bureau depended for Information In this respect almost entirely on newspaper clip pings. In this country there Is little, If ny, government or state inspection of ex plosive factories analogous to that In Great Britain. In European countries rules governing the manufacture, transportation and storage of who .must handle It. Some compounds of nitroglycerine are said to withstand even the shooting test and also the test of hav ing a redhot Iron pushed through It. "Winter is the open season ton dynamite explosions," said one of the men who had charge of a thawing house at the Pennsyl vania tunnel excavation. "Dynamite freezes at a temperature between 45 and 60 degrees Fahrenheit, and If you want to do any thing with It you must get It back to Its summer temperature. "This Is not as easy as It sounds, for It Is no small matter to get the tricky stuff I buffers, Ice cream freezer, dish washers, bread mixers, dumb elevators, are all driven by the electric motors If desired. The convenience of electrical power In the household has long been recognized and the tve of sniull motors has bejme practically a necessity. Besides the various household uses to which the motors are adapu they can be used to saw wood, cut the ensilage, cut and elevate the silo, pump water, separate the cream and churn. In the repair shop, for grinding chicken feed, sjpplylng power for elder presses, corn shellers, bottle clean ers, milking machines and a dozen other things.

Two Urge power houses, one at Mount Morris and the other at Yonkers, were provided for, each to have HO-horse power capacity, with eight substations. The thlrd-ralt system was adopted. ' On the original estimate the cost of the tlcal use of the motor in their work.

It different governments, and an employe who violates these laws Is not only discharged, but fined and often Imprisoned as well. The methods of thawing dynamite and other nitroglycerine explosives are specified by law and Infractions are punished by the courts. Magazines for storage are examined by government Inspectors and licenses Issued before they can be used. Even the keys to magazines must be given to responsible t-ersons. whose sole duty Is to look after explosives. In Great Britain the law even ' specifiea that an employe of a factory mak ing explosives must be provided 'with cloth ing made of I'.onlnflammable material and having no po-'kets. A reserve supply of high explosives Is kept by manufacturers and big contractors In bargea In the lower bay. while at Iona Island up the Hudson, Delow West Point, Is a government magazine. Each morning the day's supply is broght to the city In barges and this little craft, well known to all river men by the red flags they fly, have a right of way that none attempts to dis pute. The explosives are transported from the pler through the streets In a wagon, whl h, according to the regulations of the city, must have painted on It "In easily legible letters, at least six Inches high, 'Powder Wagon' ou sides and back."

"We read In the papers that somewhere out In the coal mlnli.g districts of Pennsyl vania a miner's hut has been blown up. It Is ten to one that fellow had put a stick of dynamite on the kitchen stove to thaw It out, and had gone away und for gotten It; or else he had left it underneath the stove and the baby had got it and made a plaything of It. "Out In the West tn constructing roads and building tunnels the workmen oftin set the sticks up along a roadside to dry in the sun. The method is good enough If the sticks do not fall against each other, or if some one does not fire off a gun near by. If either of these things should happen the chances are there will be a big hole la the ground and an opening for another powder monkey.

The expense t see of Small Motors. Each year the small electric motor finds new tasks to do, until now almost every thing about the house, office or shop which requires sniull power is operated with a motor wherever electricity Is available. The different kinds of work which are re quired of these motors every day are past all attempts at cataloguing and more ex tensive than anyone not connected with the business would Imagine. The demand for a small aelf-starting motor which Is thor oughly reliable and can be had at a small cost has been met by the production of chine, the stamp canceller for postofflce work, an automatic engine stop to prevent steam engines from running away In case the load Is suddenly removed, air com pressors for barber shops, air pumps, auto matic musiial instruments, adding ma chines, revolving signs, cue cnalkers, exer cising machines hat cleaners, coffee grind-' ern, horseradish graters, candy pullers.

Rear Admiral Brownson's flagship, the West Virginia, furnished an Illustration of the phenomenon when It was bringing President Il-osevelt home from New Orleans a year ago last autumn. It is doubtful whether under ordinary cir cumstances the cruiser could send In telligible signals more than 300, or, at the utmost, EoO miles. Yet while it was In the Gulf of M'xico dispatclies which were meant for Key West were picked up at Norfolk. Washington and even in Kansas! Though no harm resulted from the oc currence, they reached a number of ears for which they were not Intended. For some of the Inequalities In the range of a particular transmitter adequate ex planations have been found, reports the New York Tribune. One type of receiving Instrument Is more sensitive than another, and hence will respond at a greater dlstmce from the source of the wave Impulses. Again, the degree of resistance to the ether waves which Is offered by the atmcsphere varies. Sometimes an effect Is produced like the obstruction to ordinary light that Is presented by dust or thin fog. It ap pears to be Independent, too, of the paralyzing influence f direct sunlight.

B. Garland of Anaonla. Conn, former su perintendent of the fire, alarm system. He has been employing his period of recupera tion from an nccldent which happened to him several weeks ago to carry out experi ments along this lire. Mr. Garland's recent demonstration of the importance of the discovery of wire less telegraphy is a result of recent ex periments along this line carried on by some eminent French electricians. Al though his apparatus was somewhat crude, which affected his results, the experiment, he believes, proved beyond reasonable doubt that he could produce electrical waves of a high voltage and transmit power through the ulr without any direct communication. In this experiment ten dry cells were used, although a storage battery could be employed. Fifty foot from these cells In his house an Induction coll was placed and connected with an ordinary Incandescent lamp. One side of the secondary, or high tension, winding of this coil was grounded with a gasplpe, while a condenser was bridged across the two pole plena of the primary circuit. The other side of the sec ondary circuit was Ubed as the aerlul con ductor. At this distance Mr. Garland found that the ten cells would produce on the primary winding of the Induction coll a voltage of about fifteen, which varied ' c.r.'.y slightly as the distance between the cells and the Induction coll was decreased The lamp employed was an ordinary Incandescent street lamp of twenty-five ca ndlepower. One conductor of this lamp was grounded to a water pipe and a suitable resistance cut In on the other pole leading to the aerlul conductor, which consisted simply of the brass Jiole pieces attached to tho lamb.

Elect rlo power from sunlight appears more worftlerful than harnessing the streams or wind. Yet we know something of the vast heat of the sun. Solar engines for operating pumps have bwn in use In different parts of the earth for several years now, and their value la warm climates, where the number of day of clear sunshine averages high, must steadily Increase, One of the most suc cessful of these solar machines, says a writer In Bt. Nicholas, is located near Log Angeles to irrigate fruit land. An auto matic stand carrying great reflectors fol lows the course of the sun as regularly as the best telescope ever made, and the sun's rays sre thus reflected on a central point, where the boiler of a small engine is lo cated. Within an hour after sunrise th heat of the sun raises the temperature oi the water to the boiling point, and thug creates stoam: and the pumping machinery begins its day's work and keep it up until sundown. The power of the sun for heating has only leen faintly appreciated by scien tists In the pat. but ,th prediction Is made now that If all the coal should give out we would soon be able to run much of our machinery from the povrer of the sun. With Boo mirrors properly arranged to focus thi rays upon one point, a tempera ture of more than 1,000 degrees haa been ob tained. This almost equals one-fifth the hlstw-ht toniporuturo recorded by the elec tric furn io which is considered today the most powerful heating apparatus ever dis covered. As there Is no limit to the num-ttt-r of mirrors that may be employed, and as the Intensity of the heat Increases In proportion to the number of rays reflated by the mirrors, It is conceivable that a temperature may be obtained In time that will surpass anything ever dreamed of in the past or prestnt. Hitching the sun to run electiia motors for furnishing light and cw'r for our homes and factories Is the very latest achievement of the modern work of har neeslng the elements to do man's work; and one squars yard of sunshine fn the tropica may represent, on the average, ooe horse power.
