It was discovered in 1826 by the man whose name it bears, and who was an Austrian officer. Gambart investigated its orbit and announced it to bea periodic comet of short period, the second one of this kind to be discovered. It found that it had been observed on two previo 2 and in 1805. Damoiseau calculated its orbit, predicted its return in 1832, and even wentso far as to state that on October 29 of that year the two paths, the comet’s and the earth’s, would cross and the earth would not be very far away. There werc sensasional | journals even at this early date, and much | popular apprehension was created, especi- ally among the peasantry of the south of France.

Since 1872 it has not been observed, unless it proves to be identical with the comet of 1896 (Perrine), as it will then be known.

H. Bascock. The Pariahs of India. There is one native East Indian in this city wiro was much stirred by the accounts of India’s great famine in the Sun last Sunday. He is Deva Sundrum,a major ‘While he is more intereste:l in saving tbe souls of his fellow- countrymen than anything eise, he real- izes very well that this cannot be done unless their bodies are fairly comfortable. “In South India,” he said, “I waiked 3513 mles, pioneering fifty-six distriets, visiting 884 villages and 30,639 houses. In Malayalam, North Travancore, I walked 4065 miles. Here I pioneered twelve districts and visited 1631 villages and 34,796 houses. All the people With whom I came in contact on these journeys were pariahs—that is, the very lowest caste people. Poor variahs! They are all the slaves of the high caste people. To give an idea of how densely the country is populated with these unfortunate beings there are in Madras Presidency alone | 5,162,066. “The houses of the pariahs are never more than twelve fect square, and the sufferings of these people during the rainy teason and in famine are inde- scribable. They have no homes. They keep wandering from place to place by day trying to secure food, and when night comes they drop down where darkness overtakes them. Their main diet is a scant one of roots. In South India there | are fully 2,500,000 people who do not know what it is to have a single satisfactory meal from one year's end to another. Along with the periodical famine comes cholera. Those weakened by want of food quickly fall victims to the disease, and thousands die off every year. When the plague does break out the Government sometimes sends along a special medical officer to carry relief to the pariabs, but he is always a high caste, who, instead of visiting the cholera-stricken low caste, | contines himse!f 1o visiting those in his own caste. The result is that the pariahs are simply swept off the face of the earth. “Pariahs are always expected to peep at the respectable distance of ninety feet from the high-caste people. Indeed, the public roads are never opened in the vii- lage, since they are only for the use of the high caste. In certain parts of the coun- try there are special footpaths alongside all the main roads. If a pariah should | dare leave these to trespass on the main road, he would run the risk of losing his life. Oftentimes when the poor creatures see a high caste approaching on the main | romd, he leaves the path, and, hiding far | away under a bush, keeps exclaiming over | and over again in a mournful voice, as tha man passes: ‘Master, master, master.’ “When in need of money a pariah goes to his master and gets a loan amounting to $5 in American money. But he does not get this until a bond is signed by the pariah, in which he sigmifies his willing- ness to give himself to the service of the high caste for lite. India is’perishing, dying. The Government is not able to cope with the situation. The sanitary condition of the native quarters tend to spread the plague, but the pariahsdo not believe this; they think it a visitation from their gods. The Salvation Army is one of the hopesot my country. If we can win the millions away from their idols and temples they can be taught the be nehit of cleanliness, for then and pot { until then will they learn that their gods | have no control over famine and disease.” — New York Sun. ‘A LOS GATOS MAN INVENTS A WAVE-MOTOR Henry -Schomburg’s Design Promises to Successfully Harness Old Ocean’s Waves ¢ and has carefully.considered every point | came up—well, the apparatus could gen 4,7 last it looks as if the mighty, un- ceasing power of old Ocean's waves § has been successfully harnessed. o index that points toward this end vention of Henry »s Gatos, which, in & ems to have overcome | = 'many causes of failure in the past. | less to remark, this is not the first | “this great problem has apparently | Aen solved, but all indications are that | the darge working.plant soon to be tested | on the coast’in the vic ill prove a success.

It will automatically adjust itself | to the size of the waves and the rise and | fall of the tide, with no change in its de- | velopment of power. | Mr. Schomberg has a working model of | his apparatus at 3647 Twentieth street, in | this City, that gives a good idea of what | the completed motor will look like. It is | simplicity itself. In the first piace there is a wharf built of piling, with a platform | | on the top. Between a certain set of the | vliea there is a float shaped like a square | | flatboat, that rests on the surface of the | | water and rises and falls with the waves | and tide. Itis this motion that has been utilized to develop power. Attached by a toggle-joint to the center of the float is a ratchet bar that reaches upward, when the float is at its lowest point, a short distance above the platform, and when he float is at its highest far into the air. 1t is perfectly natural that the float swinging on the wave tops will rise and fall a different distance with each swell. In overcoming this lies the point of Mr. Schomberg's invention. The power developed by the rise and fall of the float is converted into com- pressed air by means of an ordinary air pump. But instead of communicating the the ratchet bar is made to engage a leve: baving its fulerum at one end and the other on the connecting tod. The raichet | par works midway between the fulcrum and the connecting rod, so that when it rises or falls one foot the piston is movea two feet. Of course this makes a loss of power, but that is easily compensated for by making the float larger. If the waves always rose and fell just one foot there would be no need of any mechanical contrivarce to make the piston give a continuous two-foot stroke. Bat they do not alwaysdo that. In case the waves rose two feet it wonld be necessary to have a four-foot cylinder in order to accommodate the stroke of the raichet bar, This point Mr. Schomberg has overcome by controlling & dog that works in the ratchet bar. When the ratchet bar has risen one foot and driven the piston its full two feet, the dog is automatically re- leased, allowing the ratchet bar to ascend freely through the lever. The distance it rises is of no importance. It may be two | tank it is only necessary to connect an or- | engine and the proper vaives to be ready power directly from the float to the piston | Cruz are now being made at the Union I As the tide falls the ratchet bar descends | of its own weight, siipping past the dos | when the lever is at the end of the down | stroke. 1t will be thus seen that no mat- | ter bow erratic or irregular the rise and | fall of the waves the piston will aiwavs | give the same length of stroke in the cyl- | inder. It will be pushed “home” witn | every stroke and so compress the air to the greatest density. The handling of the compressed air is of course no part of the wave motor. The air is forced from the pump into a tank where it is stored until needed. ‘From the dinary steam pipe with an ordinary steam to develop power. By opening the vaive in the usual way the compressed air passes into theengine the same assteam and causes it to revolve. It has been conceded that air is better for this purpose, as tnere is no waste, no matter how far it is car- ried in the pipes from tank to engine. Change of temperature also has no effect on it Mr. Schomberg has put his working model to every possible test. He has tried it in the bay at North Beach and it worked perfectly, even when large waves came in and washed all over it. The piston gave about thirty strokes a minute and de- veloped enough power to continuously run a small steam engine.

CaxoN BELL, 1o Leisure Hour, A NOVEL WHEEL FOR TOURISTS The “Omesga,” Invented by William de Witt of Santa Barbara William de Witt of Santa Barbars, a woodcarver and inventor, has studied un and put together a wheel which he holds is an improvement on any of thecycle | family yet turned out to skim the road-| As he has not yet patented his machine be refrains from making public the de- tails of his invention, but states that with a model which he has constructed he can | attam greater sneed at less outlay of pro; pulsion power with it than with an ordi nary bicycle. The Omega, as he calls it, has large wheels of any diameter chosen run- ning side by side, about two feet apart, with a small steering wheel in front; also with a small wheel behind it.- By a pe- culiar device, not yet made known, the rear wheel also acts as a brake, which can | be operated by a slight change of position | on the part of the rider. One of the large wheels revolves on ball- bearings, like the bicycle, and its mate re- volves with its axle, consequently vower need only be applied to one wheel, the in- two ventor claiming that by this contrivance the force necessary to drive the machine may be lessened about one-half. This cycle may be built for one or two persons and the great wheels may be of any diameter, from three to six feet if des sired. Any amount of lugzage may be loaded on the machine, making it convenient for tourists, hunters or any persons desiring to carry a complete camping oufit with | them. Mr. de Witt claims that the “Omega” | will cover by easy work one mile with 150 power motions, or about twenty miles an | houron a good country road. If neces- | sary for a burst of speed or climbinga. | hill, both riders can drive the machine, one by hand and the other by foot power. It can be brought to a standstill on any grade and, being somewhat like a tri cycle, stands upright when stationary. The skeich accompanying this articla was furnished by tbe iuventor to THE CaLt. He has spent over two years work- ing upon his machine. THE BACK VIEW “OMEGA.” SIDE VIEW
