The bit Is operated by tho reins, or there can be extra or safety reins added. As soon as tho horso becomes restlvo or unmanageable, It Is only necessary to pull up a llttlo harder on the rchi3, when tho links slide out and' causo a pressuro on tho horso's palate nnd tonguo and forces the mouth open.pro ventlng him taking the bit In his teeth, and at the snmo time tho curb presses J on his nostrils. Tho animal loses his freo respiration and soon comes under control. The cut shows tho bit In Its threo positions, and explains its opor ntlon. First Outline 3un. Tho early Inception of tho Gntllng gun is wrapped in much obscurity. Some French critics claim thnO their mitrailleuse antedates it, but thcro is absolutely incontrovertible proof that not only is this not bo, but that the French government mado strenuous efforts to secure excluslvo control of Gatllng's invention; failing which their competing mitrallleuso quickly fallowed tho adoption of tho doctor'B gun by tho American authorities, says Self Culture Somo good Christians have claimed that Dr. Oatling Invented his famous weapon from humanitarian motives nn nrgumtnt which hns some weight, as we well know that a mob or a regiment even, will very quickly get out of range and danger when onco it is known that such a gun is facing them. Tho doctor himself calls his invention a "peacemaker," but with tho greatest respect to him, I do not bellevo ho had any idea of saving life or anything of that Bort in mind while at work upon tho gun, whatover ho may havo thought of since. There was a Held for weapons, offensive nnd defensive, tho moro murderous tho former tho better, and from what then existed in nrenrniB and from tho fer tlllty of his own brain tho Qatllng gun was evolved tho first of its kind. His experimental gun was mado and tested beforo military men and experts at Indianapolis in 18G2. When tho first lot paid for by Dr. Catling was ready for shipment to Gen. Butler, tho factory burned and with it his guns wero destroyed and his hopes blighted Another year and many thousands o dollars were spent to remnko tho pat terns and drawings nnd a new batch of guns a year of heart-burning pinching and sacrifice that many of us, at somo time or another, havo ex perlenced and thercforo ono with which wo can sympathize. Oen. Butler used somo of theso guns on the James river, near Richmond, and tho way in which their inventor cherishes tho rec oVds of tho execution wrought by thera Is amusing when ono thinks of tho hu mnnltarlan theories attributed to their origin. In 18C0 the government oftl daily approved tho gun and, after tosts that make an inventor shiver to think of, placed nn order for 100. Then not only did tho powers of Europe order guns, but bo did China, Japan, Slam Egypt and the South American coun tries. A machine gun that spread devastation in a swath wider than company of infantry nnd llred Inch bullets at tho rate of 1,200 a minute (to-day. rired electrically, its speed is slightly in excess of 3,000 per mlnuto) was a revelation to most foreign ox perts and no Christian or other power could long withstand tho temptation of mowing down its Christian or other foeo at any such rate and by machln ery. Threo llcllpes. In this, tho last year of tho nine tecnth century, which, by tho way, is not n leap year, though it Is divisible by four, there will bo threo eclipses, two of tho aim and ono of tho moon. The solar ccllpso, taking placo on tho 28t if Mi; will bo vlslblo throughout tho United Stutes, nnd bo total from the southern part of Virginia down through Mexico, wliilo north of Nor folk, Vn., it will lo partial. In tho city of Baltimore It will begin at VMS n. m. Of all phenomena of naturo there is nono so profoundly impressive and awe-inspiring as a total eclipse of tho sun, and a trip to those regions of tho country through which tho shadow of the moon will aweep on the 28th of May is well worth undertaking. It scarcely admits of any doubt that many thousand people of the northorn and mtddlo states of the -Union will go to see a phenomenon which compara tively few peoplo havo over had tho privilege of beholding. Tho nvcrago breadth of tho eclipse track will bo nearly 60 miles. A second ccllpso of tho sun will occur on tho 21st of No vember. It will be nnnular, but not vlslblo In this country. A partial ccllpso of tho moon will take placo on tho 12th of Juno, though it will not bo vlslblo in this country. Deadliest Tol on Known. Tho discoverer of prusslc acid was Instantly killed by Inhaling ono whiff of his own handiwork. Puro prusslc acid Is nevor sold or handled. The smell of It 13 always fatal. It kills not In thrco minutes or halt nn hour, but the Instant It enters tho lungs ns a gas. Tho mixture ordinary boiu as prusslc acid Is 98 parts water to two parts of tho drug. Even In this form It Is very deadly. A 20 per cent mix turo of tho acid would kill nearly as quickly as If pure. Atropine, though It ha3 no harmful odor, Is so deadly that as much of It as would udhoro to tho end of a moistened forefinger would Instantly causo death. Cyanldo of potassium has a pleasant smell. which la not Injurious, but n small quantity swallowed kills at once. Pure ammonia, If Inluled.would causo death almost as quickly us prusslc neld. When a carboy of nitric acid Is broken someone has to suffer. It will burn wood, eat through Iron plates and de stroy whatever It touches. Such an ac cident once happened In nn neld fac tory. Everyone ran away, leaving the acid to amuso Itself by sotting Are tC tho things. Soon it vs seen that tho building would bo destroyed and hun dreds of peoplo thrown out of work, and four men volunteered to put out tho flro In tho ncld room. They buc cecded and came out feeling all right. Five hours .'iter all wero dead. Tho I'l Mont Aim of l'hyslcs. In his cveiUng address on "The Cen tenary of tho Electric Current," deliv ered beforo tho British association, Prof. Fleming referred to Hertz' proof that electrical energy could leave a rod In which a rapid oscillatory current was set up, and could travel with tho speed of light outwards in all dlree tlons. It existed as freo radiant or wave energy In tho ether after It left tho rndlator and beforo it reached tho receiver. Both optical and electrical phenomena had compelled tho n3sump tlon of nn Imponderable material which could bo tho vehicle for energy In cer tain forms. Tho aim of physical in quiry at tho present time was to de vlso a theory of tho ether, such that from tho simplest posstblo assumptions could be deduced tho facts of electric ity, magretlsm and optics.

SInco tho discovery of tho first dla mond at Holtfonteln, In August, 1897, there has been a considerable develop ment of the diamond Industry in tho Transvaal, and In 1898 tho output amounted to 11,025 carats, valued at $43,151. The largest stone found thoro this year weighed 38 carats. Tho average valuo of the diamonds in tho Pretoria district Is stated to bo $3.89 por catat, thoso found at KImberley at $C33 por carat and thoso occurlng at Jngersfonteln, in tho Ornngo Free Stato, $8.27 per carat. Tho area of dla mondlfcrous ground in the Transvaal Is very extensive, but Its thickness Is not considerable. Tho weight of tho diamonds found throughout tho Trnn svnal in 1898 was 22,843 carats, valued at $212,812. A LHe-Svl: Colin r.

A woll-drcsscd woman stands spon sor for a rulo which every woman could adopt with distinct pro lit to her personal appearance. I cannot quoto It, but 1 can glvo its idea in words which will bo plain enough to follow. A woman can never err In tasto If alio matches her hair in street attlro, her eyes in houso wenr and her complexion In evening clothes. That is not to bo taken quito literally tho hair may bo light brown, which will hnrmonlzo with various shades of that color. Tho eyes may bo palo blue, but they do not necessitate pale bluo dresses, although that shado would undoubtedly provo the most becoming. A pink complex ion would not always call for that tint, but for harmonizing shades, although tho strict letter of tho rulo would bo safer for thoso who are confessedly lacking in color Judgment. At all events It would savo us from many of the sights which dally meet our eyes. When I read a fashion nolo telling of tho popularity of green nnd bluo com bined I feci a premonitory shudder at what I am doomed to witness Inter on. None but nn artist can successfully comblno violent colors, for certnln shades only are capablo of a pleasing combination, yet women who persist In following every fashion, however wild nnd absurd, will evolve startling and hideous costumes which would never havo been dreamed of had tho fashion not been suppressed. An "an nouncement of the rage of black and whlto is a different mntter, for 1 havo yet to aeo whero thoso two refuse to blend. Black Is a serviceable color, for it serves aa n background to nil others and will often settle n vexed question of economy. Soft shades nro becoming to nil, vivid colors nro for tho fow. I heard a young woman ob ject to a scarlet throat ribbon wprn by her friend because it took away what llttlo warmth thero was In her rather palo faco nnd suggest something more dolicato. Sho was right, too, for senr let is exceedingly trying when laid against tho majority of faces. If it was rellovcd a bit at tho throat with whlto you would seo a vast chango for tho better. Thoro is much art in dress ing tho neck. Tho long thront needs high collars, broad ribbons nnd many folds, while tho short ono can stand but n mcro line of any of theso things. A short collar on n long neck takes- away every particle of stylo from tho owner'B appearance, and a high ono will glvo a touch which transforms her. Tills adapting of the fashions to one's own points Is a fascinating study if you choso to make it so, and one that makes a woman distinctive. Be cause a high colffuro is considered tho nemo of fashion should not bo n reason for tho woman who is hnndsomo in n low ono to change. Such a chango might transform her Into a vory ordinary-looking woman. Thero never was and nevor will bo n atylo that can not bo modified to cvorybody'a needs tho manner of doing It Is tho sticking point. Havo you never beon puzzled to llnd Just what mado ono woman stylish nnd attractive, whllo her neigh bor, prettier, perhaps, was notlceablo for nothing but neatness?

It is a mistake to lavish money on drawing rooms and sacrlllco tho kltch- en. Kitchen utensils nro of tho first Importance. Tho cook cannot do hor work well without propor tools and proper environment. A kitchen outfit costs little. New oilcloth for tho floor, tablo and sink Is cheap and adds Im measurably to tho contentment of tho maid. An attractlvo kitchen bespeaks tho good housokcepor. It is easier to convince the servants of- tho desira bility of keoplng it clean. Neat tin nnd wooden boxes with labels aro a do- lightful acquisition to tho kitchen closets and much moro pleasant to handle than leaky paper bags. Col ored paper with pinked edges for tho shelves will work wonders for tho gen eral effect and a growing plant or two gives nn air of luxury which surprises thoso who havo never tried it.
