A TRAP FOR WAR SHIPS, They Might Eo Caught B 7 a Chain cf Great Magnets. One of the Possibilities of Electrical Coast Defenses—How to Protect New York Harbor—Col. W. R. KinS's In vention and Its Uses. [COPTHIGHT, 1896.] So many people have been talking and thinking within the past few weeks, and even nervous about the ways and means of defending the coasts of the United States against attack by a for eign power that the progress of elec trical experiments in this matter may be of interest. Since the last war in which the United States was at all practically in terested, applied electricity has done so much to change the methods of com munication and locomotion both on land and sea that more may be expected from it. We had the Atlantic cable in 1868, which condensed weeks into days ns far as commerce is concerned be tween the old world and the new; also the telephone, which cuts into the mail methods for moderate distances, shortening the time of supply from days to minutes; then the street trolley car, which is an example of machinery propelled by electricity that has so greatly facilitated the transportation of passengers and mails in cities—to eay nothing of the electric light. All of which is applied electricity. Out of what was at first mere idle curiosity I took the trouble to find out how far electricity can be relied upon es an aid or a single factor in defending our coasts and harbors, and the result is here' given. In November, 1894, Col. W. E. King, then commanding engineer at the United States engineering school at Willet’s Point, on Long Island, tried to see how powerful a magnet he could make, and of what use it would be. He took the largest steel cannon he had (of which it is unnecessary to give the dimensions here), plugged up the muz zle with soft metal, then wrapped the barrel with copper wire, thereby mak ing an instrument that could be great ly magnetized by a current of electric 'ty. When the current was turned on battle, snips approaching hnrbo~s and coasts. Prof. Bullock said: r,,,"1 know of Coi- King’s grant magnet. (J Le mafjneltlc P°wer in it could not be transmitted through copper or any sbcl ?f W3rf, runil'ng out from the ' 5® sinnU receiving magnets lying at the bottom of the channel entrance to a. harbor, because the currents slope ol.. as it were, into air or water as they proceed from the great magnet, there by losing force. But there is nothing to hinder the planting of a line of these great magnets across the entrance to a harbor several miles at sea and mag netizing them through cables from the shore at short ■ notice. They could be sunk to the bottom of the sea, and would act just, as efficiently under water as on land. f or instance, take the entrance to Kew York harbor. The chart here, as J 011 see, shows that the channel is very narrow, and that is one great ad vantage. If we should take a few old cannon barrels and make magnets of them, like Col. King’s, they could be dropped in a line across the channel a few hundred feet apart, and here and there around Sandy Ilook, connecting them each with a powerful battery on shore. The apparatus would be com paratively inexpensive and simple, bach one would be what we call a tem porary magnet, that is, one which could be magnitized temporarily by a current of electricity trasmitted through the cable from the shore. A permanent magnet, or one retaining constant pow er, could hardly be made large enough to be efficient, and if it were, its con stant force would endanger all incom ing vessels all the time. But a mag net, or line of magnets like Col. King’s could be magnetized and made active in a minute, and the current could be shut off quickly. The power of the magnet Would depend upon the strength of the current received from the shore. A ovv suppose a battle ship were com ing ftp the channel into New York har bor. The ship is made almost entirely of iron and steel. The line of great magnets lying under and across its headway, could be powerfully magnet ized. When the ship approached with in 200 feet of a magnet, the latter would leave its bed and cling to the forward | keel, and if the ship should pass directly THE PIECES LEFT THE TRAY AND CLUNG TO THE CANNON. nil small pieces of iron lying1 near the cannon began to leave their places and cling to the great magnet. A man took a dinner tray loaded with pieces of scrap iron weighing from an ounce to a pound, and when lie was within 100 feet of the magnet the pieces began to leave the tray and cling to the can non, and a little nearer the platter was as clean as that of Jack Sprat and his wife after they were through eating, oext a crowbar weighing 25 pounds was taken near the cannon. It flew out of the man’s hands and stuck with such force that two strong men were re quired to pull it away, and this could be lone only by a sudden jerk. It was noticed also that the mag compasses in the immediate neigh borhood were appreciably depleted by he greatest, magnet in the world. vwspnper reports at the time, hr d. King- as saying that a ship’s '^5S)uld be deflected six miles at 8eai but t$js was an injustice to the Colonel, and herewith is given an ex tract from aNprivate letter written by him at. the time to show what was really lone. After deprecating the wrong itatements by certain newspapers, Col. King wrote: D- S‘ Engineering School, Wlllet’s Point, "Queens County, N. Y., Nov. 27,1894.

Heck of the department of natural in relation ‘ ■■^Vcs’ Columbia colleg he effect that a combination of great magnets might have upon over one of the magnets, the depth of water below the keel is so slight that the magnet would come up to the ship with great force. Having once touched the keel, the electric current from the shore would either stop the ship, or the magnet would be dragged along the keel until it would strike the propellers, which would be done with such force as to crush them. “In case the first magnet should not be strong enough, and the ship should cross a second, the second would seek the end of the ship opposite the first., forming the two poles and magnetiz ing the entire ship. Then it would be impossible for the ship’s strain power to overcome this force, while all mov able iron would be stuck solid. “All this is very plausible and could be made practical. Of course, what is done in New York harbor and along the immediate coasts could be done elsewhere. It would cost very little to try this first on one of our own bat tle ships entering the harbor, and little harm could be done, for the current from the shore could be shut off im mediately at a signal from the ship. “As to the deflection of the compass of the ship, when one of these mag nets should strike the keel, the com pass could he made to whirl like a school boy’s top, for it would be an al most direct contact with the mageel.’’ After investigating the subject thus far, oue of my own wild ideas is that, in a sudden emergency, the submarine cable connecting these deep-sea mag nets with the shore could be connected with a trolley-car power house, and the magnetic power could be quickly run away up to the top of the alphabet, and a battle ship would hardly realize what had struck it.

How They Struggle Through Their First Season at the Capital. Snubbed by the Old Merahm-The Coun try Legislator's Wife It Appalled at Her Visiting I.lst, and the City Woman Calls Upon Everybody. [copyright, 1896.] The usual rush of newly-elected mem • hers has brought to Washington the usual army of new women—not the new women of the comic papers, but the women who are new to Washington —the new congressmen’s wives. While they are objects of the liveli est interest to themselves and their friends at home, the women are a.source of perennial amusement to Washington society. There are many types, each interest ing in its own way. The woman from a far western state, who, perhaps, in her ovyi home has leu a quiet life, with only such mild dissi taken the first, decisive step into Wash ington society. But she is not long in realizing that the dress that was considered a triumph of the dressmaker’s art at home is al most. dowdy by contrast with the gor geous costumes she set's about- her. She finds that instead of sitting down and “visiting” with Mrs. Senator Blank froai her own state, she gets a formal shake of the hand and is passed on with out. a word into a room filled with strange people. She knows nobody and apparently nobody wants to know her. She makes a speedy exit, past her in different hostess, and goes hack to the dingy hoarding house to tell her hus band of her experience. She isn’t quite sure whether she likes Washington or not, hut feels a bit consoled the next, morning when she sees her name in t.he list of “those who were calling yesterday.” This list is compiled carefully each day by the good-nat.ured socity report ers for the daily papers. It has con soled many a woman for the snubs and she gets a fobmai shake of the hand. pations as country fairs or church festi vals, becomes the envy of all her friends tv hen her husband iselected tocongress. Possibly as the wife of the mayor of the town, or the daughter of its leading merchant, she has been a woman of some prominence and a leader of its social gatherings. She looks forward to taking a conspicuous part in the gayety of Washington, as in that of her own town. She leaves her home with her head in a whirl of giddy anticipa tion. She and her husband have only vague ideas as to where they will live, but look forward to luxurious quarters in a hotel as the proper thing for people in their position. It takes them but a short time to discover that a congress man’s $5,000 a year will not support a great degree of luxury, and they set tle down very likely in a boarding house with the privilege of the parlor. Washington is full of these places. Most of t hem are kept by representa tives of decayed gentility. The land lady regales her boarders at table with stories of her former wealth and ele gance “befo’ the wall.” She is perhaps employed in one of the departments, and leaves the management of the house to slipshod negro servants. In the depth of this typical Washing ton boarding house, the first dream of congressional luxury is dissolved. On her arrival the new member’s wife feels a little timid at what she lias disappointments of a first round of calls. A white house reception is something the new congressman’s wife has long looked forward to. She starts with less trepidation than when she made her first calls, for her husband is with her, and he has that breezy air of self-confi dence that is typical to the new con gressman. He lias not had time to re alize what a small figure an every-day congressman cuts in Washington. She soon finds herself in the midst of a crowd made up of everybody who is prominent, in the capital, either socially or politically'. The resident society' 3s well repre sented. So is the foreign element, anil the army and navy. She looks enviously at the women abouther, so well-dressed, so graceful, so entirely at ease. Every moment she realizes more the need of experience and training for her new po sition. After a few experiences she feels more at home, and even learns to “patronize” some less experienced sister. This is a common type. The woman who can afford to hare quarters at a hotel is just as amusing in her way’. She thinks the “reception’ given every week by the proprietor of the house is a very brilliant affair, and the attention she receives as the wife of Congressman blank completely turns her head. The wife of the member from the mmm NOT AS MUCH 'UP TO DATE ” AS SHE THOUGUT SHE WAS. before her. The unwritten laws of Washington society are an enigma which she cannot solve for herself. She seeks the wife of an older member, who pities her ignorance, and patronizes her with an air of superior wisdom born of experience, and offers perhaps to pilot her through the uncertain shoals of so ciety as she has found it. The new member’s wife is dismayed when she finds she is expected to make calls on the wives of the president and vice president, the eight cabinetoffleers, the nine supreme court justices and tire 88 senators before they call on her. She hesitates, but finally gains courage and sallies forth with her new cards and her best gown. She feels as she goes from house to house that she lias realized her ambition; that_ she has] large city is less open to ridicule, for she comes with more experience in matters social, but she frequently makes blun- j ders through her ignorance of certain rules of etiquette peculiar to Washing* j ton.

Open* on Washington'* Hlrtliday—8ouv© ulrs of the Confederacy to lt«> l'rrtorved l>y s Society In ItlchuiouU—The Seccaslonlst*' Constitution. [COPTRKlUT. 1896 ] The old mansion of Jefferson Davis is to be opened ns a museum for relies of the war. It was built about 70 years ago, and after the evacuation of Rich mond was used as headquarters for the union army. Though more than. 30 years have elapsed since Lee laid down his sword at Appomattox it is only in the last two years that any movement lias been started to j>erpetuate. the memory of the confederacy by the preservation of its famous spots at the capital of the nation which lives but as a mem ory. And by a wise choice the formal opening of the new museum, the house in which Jefferson Davis lived as pres ident, is to take place on the 22d of this month, the same day on which is cele brated the birth of Washington. The old Davis mansion stands in Richmond, Va., in a quiet part of the city, on a corner at the intersection of May and Twelfth streets. It is on a high hill, from which one has a view of a deep ravine covered with rambling shanties and waste lots on one side, while on the other the ground rises towards the west, where, the street loses itself in the more fashionable quarter of town. The mansion faces the north, and its front covers the eii • tire portion of the occupied block, hut just opposite ic a long red brick build ing which completely shuts out the view in that direction. The house, which is an immense brick one, has been recently painted light gray. It was built about 70 years ago by a Judge^trokenborough, whose family lived there for some time. Here it was that the cabinet of the confed erate states met, here that Lee and Davis discussed the fate of the cause, and here, too, were enacted some of the most brilliant, and, later on, some of the most pathetic scenes of the civil strife. It was in ’02 that the Davis family took possession of the man sion, and Mrs. Davis set to work to make it a comfortable and attractive home. She gave state dinners, and he* lost his life. Gen. Jnckson's old sor rel horse, which has been mounted by a taxidermist nnd is now at the Soldiers' home, will find its way to the museum and so will the saddle of Lee. which is at the same place. Jackson’s rusty lit tle quadrant is also shown. Gen, Curtiss Lee presented to the museum a pistol which was worn l>y his father, Gen. Robert K, Lee. through out the war. Of the belongings of (Jen Jeb Stuart there are sable, plumes which once nodded over bis head, and the old haversack which he always look with him on his marches.

In 1871, the residence, then in posses sion of the city, was turned into a school known us the “Central.” The furniture was sold and thus scattered about the country. Of late years the mansion has fallen into decay and it was fast becoming a desolate ruin, when its aspect attracted the attention of some ladies of the city, who imme diately formed an association to re store it and convert it into a museum. One enters the house by a series of shan't steps which lead to a small, semi circular hall. On each side of this hall are niches in which stand bronze statues of feminine figures. This en trance has two narrow halls leading off on the right and left, but just in front it opens into a large, lofty room which was one of the parlors used by Davis. At the bock of the house and on a level with the second floor is a ■vide portico whose roof is supported by ten white pillars. I tie cost of repairing has .so far been about $14,000, which was covered by I the $30,000 proceeds of a bazar held in the city several years ago. Half of that fund was donated to the monument erected in honor of the soldiers and sail ors, and the rest was kept to work on t he museum. A room has been given to each one of the confederate states, are gent from that state being appointed to secure relics and place them in the right chamber. Maryland and Ken tucky, though they did not secede, are represented, because of the large num ber of soldiers which they sent to the southern armies. Miss Mildred Lee and Miss Winnie Davis are among the ladies in charge. Those who have in their care the col lecting of relics have succeeded in se curing a large numlier of valuable curios. These will be catalogued and assigned to the rooms belonging to the states from which the relics came and will be in place within a few weeks, though it is doubtful if all will be within the house by the day of the formal opening on the 22d of this month. Tlie most valuable of any col lection possessed by the association is that which was donated by the late Mrs. Du Reunne, of Savannah, Ga. In this collection is tlxe greatest treasure owned by the south—the original draft of the confederate constitution with the interlineations and erasures. It is about the size of the Declaration of Independence and will be kept under glass and carefully guarded. In the museum also reposes the last missive ever written by Gen. Stone wall Jackson. It was to Lee and was written while Jackson sat on horse back just before the fatal ride in which grains the whole mess of nine men were to exist during several days' inarch. The coffee is imloa.sted and was not used bccuu ■ the men did not have time to dismount and prepare I'ood. The scrap book kept by Mason while he was a prisoner at Fort War ren, Massachusetts will be in one of the eases, and in another is a hook con taining the autographs of all the con federate generals. About the rooms in cases will be guns, swords, pistols, old uniforms, photographs, letter's, shells, flags, tents and everything which was in auy way connected with the war. All over the south people have promised to send in their treas ures, and within a few years’ time this museum will hold one of the most val uable collections in the world. The o|M'iiing exercises will be of an interesting character and will be free l.o the public, refreshmentsbeingserved in the house. The museum will be in order by that time, but not absolutely complete till all the various collections are in from those who have promised to make such gifts. V. Stuabt Mushy Coi.emaw. A Drop of Water. Water that is now in the ocean and in the river has been many times in the sky. The history of a single drop taken out of a glass of water is really a romantic one. No traveler has ever accomplished such distances in his life. That particle may have reflected the palm trees of coral islands and have caught the sun’s rays in the arch that spans a cloud clearing away from the valleys of Cumberland or California.. It may have been carried by the gulf streams from the shores of Florida, or of Cuba, to be turned into a crystal of ice beside the precipices of Spits bergen. It may have novered over the streets of London and have formed a part of murky fog and have glistened on the young grass blade of April in Irish fields. It has been lifted up to heaven and sailed in great wool-packed clouds across the sky, forming part of a cloud mountain echoing with thun der. It has hung in a fleecy veil many miles above the earth at the close of long seasons of still weather. It has descended many times over in showers to refresh the earth and has sparkled and bubbled in mossy fountains in every country in Europe. And it has returned to its native Sides, having ac complished its purpose, to be stored once again with electricity to give it new life-producing qualities and equip it as heaven’s messenger to earth once more.—Charles S.
