WILSON, who appeared erday in United States Commissioner Heacock's court representing Bert Herrington in the case of the United States vs. Kim Quey, was hoisted clean out of the case by his own petard. His client turned the tables on the gang of highbinders that | were fighting for the possession of her- self as a chattel, and the ring was filled with consternation. If her story is true one lawyer may be disbarred. Kim Quey was arrested at Mayfield by Chinese Inspector Gardner for being ille- gally in the counts he having discovered that she was one of the show women who | ere to take part in the exposi- Bert Herrington took her in a buggy and drove away from the town, but was overtaken by Dr. Gardner. Her- rington jumped out the buggy and made his escape and the woman was re- arrested. In the deportation proceedings day morning before United States Court Commissioner Heacock, Dr. Gardner was the first and only witness. He testified that the woman was a laborer and had no certificate of registration or paper entitling her to remain in this coun- Then Mr. Wilson walked into the trap. He asked the witness if the woman had not testified at Mayfield that she was a native of the United States. The in- spector replied that she had, and that she had afterward confessed that her testi- had come tion at Omaha. ster- | other | mony on that occasion was false, that the | t she had come here with a Exposition people and that she T been here before. of her confession. The story had been taught her, he said, by Wong Fong, the Chinaman charged with abduct- ing her; by Wong Sing, the man who afterward went through a form of mar- riage ceremony with her, and by Lawyer Herrington. According to her statement they said: “You must testify thus in order to clear us, for if you don’t our lives‘wouldn’'t be worth anything. We would be hanged. You must say that you were born in San Franeisc hat you never were out of San Francisco: that you were not willing to stay in the Chinese Mission Home; that you wanted to go away h Wong Ling Ting; that you had known him for more than a year and that you wished to marry him—in’ fact, that you had married him; that you love him and that he is your hus. band. You will say also that everything | that has been done with you has been done with your consent, If you don't tes- | tify as we say a bullet will be put through | your head. |, Mr. Wilson announced at this point that he would withdraw from the case. It was | Mr. Herrington's case, he sald, anyhow. | The court took a rec until 11:30 o’clock | to allow Mr. Herrington an opportunity of come, and the proceedings were continued until ‘this afternoon at 2 o'clock. HEAVY FINE IMPOSED ON SALMON PACKERS Judge Morrow Demonstrates That There Is No Profit in Con- tempt of Court. Joseph Hume, Hume Brothers and the Hume Salmon Packing Company were be~ fore United States Circuit Judge Morrow vesterday to show cause why they should not be punished for contempt for having disobeyed an order of the court prohibit- ing them from infringing the patent on a certain machine used for filling #almon cans. It was alleged and proved that the de- fendants had been violating the injunction since March, 1847. Judge Morrow found the defendants guilty of contempt and together with costs and $250 counsel fees. ' Tt was also orderea that if the fine was not paid in five days Joscph Hume, the legally responsible head ©of the defendant firm, should be impris- oned until_the fine should have been paid, caid period of imprisonment not to exceed six months. It was ordered further that the machine used by the Hume corporation be sur- | rendered to the United States Marshal, the Marshal being ordered to destroy the —a Horseshoers Incorporate.

TRANS-ATLANTIC TRAVELERS Furnished Special Attendants by the Pennsylvania System. The bureau of attendants for trans-Atlantic travelers established in Jersey City and New York City twenty vears ago by the Pen vania System, has proven a great convenience to persone making European trips and tourists arriving in America at that port. Tt will be particularly convenient for visitors to the Paris Exposition because the departure | docks of most of the Atlantie Steamship Lines | are convenient 1o the new Jersey City Passen- ger Station of the Pennsylvania Ratlroad Company. This bureau consists of experienced agents whose Qutles are to meet passengers arriving in Jersey City and New York over the Penn- eylvania Lines and assist them in arranging for trans-Atlantic trips via any of the steam- lines by conducting them to steamships and ajding in preparations for a trip abroad, ‘Phese agents will provide cabs operated by the Pennsylvania System and aid passengers with their bagi . They are fully posted on Mmatters pertaining to steamships leaving New York, and arrangements can be made through them for procuring steamship tickets in me- vance. ey also meet incoming steamships to aid travelers in shaping_details for continuing Journeys from New York over the Pennsyl- Yania Lines by furnishing tickets, arranging for the transfer of baggage from steamship docks after it has been passed by customs in- spectors, and having the same checked through 5 deatination. They will reserve sleeping car accommodations and relieve persons of the foregoing details, making themselves useful as attendants and guldes free of charge.

PHOTOGRAPHY IN COLORS. (Concluded.) There are two other methods of color photography more recent and somewhat more direct than the three-color process. These are the interference method of Lippmann and the diffraction method in- nted by Wood. Lippmann’s Interference Method. In this method two things are necessary —a transparent photographic film not granular in structure and a metallic mir- ror. Suppose that the film is in direct contact with the mirror and that a beam of light of a single color—that is, a single | ave length—fall it. The light passes through the film. strikes the mir or and a train of waves is sent back through the film. These reflected waves meet the oncoming direct waves and the result is the establishment of what are lled “‘stationary” or “standing’” waves, | such as may be seen when a tight string is vibrating violently as a whole or in equal parts. At certain points the direct and the reflected wave urge the string in the same direction and the result is a motion which is the sum of two: at points midway between these points of greatest motion the direct and the reflected wave urge the string in opposite directions and the result is no motion at all. A similar effect may sometimes be seen in water when the waves are reflected from a smooth rock or the planks of a pier or a ship. Such an action as this taking place within the film produces planes of maxi- mum light action and planes of minimum on half a wave length away them. The emulsion will be acted upon at the planes of greatest motion and not at all at the planes of no motion. There will, therefore, be strata of metallic silver deposited, the distanca between adjacent strata depending upon the wave length. The strata formed by the action of violet light will be nearest together and those due to red light farthest apart, and even in a _thin film there will be as many as 500 of these layers of deposited silver. 1f instead of light of a single color the colored image formed by a lens falls upon the sensitive film and mirror, the. result will be a distribution throughout the film of layers differently spaced at each point in accordance with the color. Seeing the Image. When white light is allowed to fall upon a plate obtained in this way, it is reflected at each of the planes within the film and interference takes place in such a way the particular color hened It is the same action which gives color to a soap bubble. Part of the light is reflected at the first surface, part goes through which formed the planes is stren, | and is reflected at the next and joins a wave reflected at the first.s As the extra distance traveled is an ex: multiple of the wave-length of the color that pro- duced the layers, the light of that par- ticular color in each of the reflected waves will be in the same part of a vibra- tion and the color will be strengthened. other color the two re- flected waves w{ll be in different parts of a vibration when they join again and will therefore be partly or wholly destroyed. If there were only two planes the select- ive stnn‘lhenlng of the reflected light of one wave length would not marked. But, as there are hundreds of planes, one | after another, the final result is that prac- tically only light of one color—the color that produced the ?lnnel at that point— emerges from the film. The plate hdy with the film side at d in a_ tight holder The space the back is th fooaed with it s en mercul and the exposure is made. There is g other change from the usual practice, the from | | overations of developing and fixing being as usual. The plate must be viewed at the same | angle at which it was en. For, if the | incident is changed the colors change, the red changing to orange, yellow, green ana { 50 on to the violet end: 4 | the film is wet it swel tween the layers increa | change in the opposite order. Wood’s Diffraction Method. A still more nt method is that due to Wood, in which the color effect is pro- duced’ by diffraction. Before describing [ the process efore, we must first un- derstand what diffraction is and what ef- | fects it produces. | , Nothing in regard to light is more firm! | impressed on the mind than that it cas@® sharp shadows. This, however, is entirely question of degree. The impression is just as firm that sound does not cast sharp shadows. The existence or the absence of | shadows depende on tire relation between | the length of wave and the size of the obstacle. The water on the leeward side of a ship is comparatively smooth, if net | quite so; and sound shadows occur behind large obstacles. Water waves bend around a stake just as sound ves bend around small obstacles. Light waves do the same thing, but as the light waves are so very | short the obstacle must be very small to produce the effect of the stake in the water. A body of the dimensions of a hair or a fine line on glass will do this, and when the different sets of waves meet {on the other side they interfere, causin added light where crest meets crest an | destroying each other where crest meets trough. Thus alternate bands of light | and darkness are produced which may be | clearly seen under favorable conditions with the proper apparatus. This effect is very greatly increased by ruling a great | many lines clo: her, the lines all be- | ing of the same width and separated by spaces of the same width. Such a set of ruled !nes on glass or on other transpar- | ent or highly reflecting body is called a | diffraction grating.” | Action of Diffraction Grating. 1f the image of a light of one color only, ch as the vellow sodium flame, is formec | by a lens upon a sereen, and a grating put in front of the lens. fhere appear other vellow images on either side of the central mage separated from it and from each | other by dark spaces. If the color of the | light Is bine the spacing of the side im- ages is smaller, each blue image falling | néarer the central line than the corre- sponding yellow, and images from a red source -would have wider spacing than the | yellow. In this way white light is broken {up by a grating and spread out into a series of spectra on either side of the cen- | tral_line. ~Moreover. the spacing of tha | lines of the grating determines the dis- tances separating the spectra, finer ruling causing the images to spread out mere widely. Evidently. then. by using grat- ings of different fineness of ruling we may j cause the spectrum produced by the sec. ond—the spectrum nearest to the central image since it Is the brightest_to lap | upon the spectrum produced by the first and that of the third grating to lap upos | the two others. Indeed, the ruling of the | gratings may be carefuily determined. sq that the red from the first, the green from | the second and the violet from the third will all fall upon the same spot. An eve placed at that spot would see red, green violet or any of their compounds, includ- ing white, according to the relative strengths of the simple component colors It is_this action which is the foundation of Wood's method. The Process. From what has been said it is evident that this method is in a sense a three- color method, but the primary colors used | are pure spectrum colors which by an in- | genious arrangement are produced aute- maticaily in the film itself. In the fin- | ished peositive the red component at each | point s represented by a portion of the grating producing red at the view point the green component by a portion of the green-producing grating and the violer com) ntv&{.‘l portion of the grating pro
