Ufte g^antha. OEOKGE W. MAGKE, Editor. DUrüYER, MONTANA. The new cone on Mount Vesuvius, formed during the late eruptions, has been suddenly engulfed into the crater. The mountain has now assumed its old appearance. Dr. Hans Blum, one of the biograph ers of Bismarck, has become mentally deranged, owing to his losses through the recent failure of the Leipziger bank, and has been placed in an asy lum. He is a son of Robert Blum, who was executed in Vienna during the revolution of 1848. In cold countries, where snoW pre vails during a long winter, many of the animals' change the hue of their coats to a white tint. The Arctic bear and fox are white throughout the year. The northern hare is brown in sum mer and white in winter. The weasel is especially curious; it retains its brown coat until the first snow ap pears, and then whitens in a few hours. Forty years ago President Lincoln appointed John Jap Jackson of Park ersburg, W. Va., judge of the United States circuit court and he still holds the position. During all these years he has never failed but once to hold court at the appointed time. That was when confederate troops under Gen. Loring were in possession of Charles town, where the sessions were held, and the session assigned for that date had to be postponed. It is announced from Constantinople that the Sultan has had to be bled. For some time he has manifested a somnolent tendency. Recently he slept continuously for fifteen hours, and af ter awaking for about an hour he went to sleep again. He was only roused by his Arab body physician applying ice to his temples. The physician then intimated to the Sultan that his condi tion indicated excess of blood, and that bleeding was necessary in order to ob viate danger to the brain. After mak ing the doctor swear on the Koran that no injurious results need be ap prehended, the Sultan let himself be bled, and his quick-witted servitors gathered the blood into tiny phials, which can be sold to the faithful at 100 piastres each. Dr. L. O. Howard, entomologist of the department of agriculture, has just made public some startling state ments of the property losses caused hy insects. He believes they aggregate over $300,000,000 a year. The Rocky Mountain locust or western grasshop per in 1874, ate up $100,000,000 worth of growing crops. The chinch-bug alone has eaten $300,000,000 worth of corn and wheat in the western states since 1850. As for the mosquito, apart from the losses believed to be due to its pernicious activity in the spread of yellow fever and malaria, it is an im mense depredator of real estate val ues. A New Jersey newspaper re cently estimated that its extermina tion in that one state alone would add to its real estate valuation not less than $100,000,000. The miners of the town of Pas Da Calais have elected Mile. Lea Bourdon as their queen of the coal carnival. This young woman is in the coal trade in the capacity of a sifter, and al though her work is so grimy she has a beautiful complexion, which, no doubt, added to her good character, gave her the necessary number of votes, although the competition was keen, her fellow-candidates being drawn from the cleaner walks of life. The car which carried the queen and her maids of honor was decorated with flowers, picks, lanterns, etc. Mile. Bourdon is only 17, and the coronation in the center of the town made a very beautiful tableau. To be coal queen en titles her to a small annuity from the treasury of the town, and with her French thrift she will save this for her dot. As the steamer Sheffield was leaving ,the river Scheldt one evening recently the captain and passengers observed the unusual phenomenon (in thse lati tudes) of a large waterspout. The steamer was a few miles off West Capple, and from a heavy thunder cloud lying due west of this point, and computed to be about ten miles dis tant, a dense black column was formed, which appeared to fall by a sinuous course into the sea. At this I distance the surface of the sea—where the waterspout touched its surface was at once surrounded by a smoke like obscurity. Hundreds of tons of water must have dropped heavily into the sea. The black line of communi cation between the cloud and the sea fell precipitately at first, then for some distance appeared to encounter I a fresh current of air and was borne along laterally, after which it dropped into the sea. The phenomenon contin ued dashing up the surface of the sea jlor about four minutes. NOTES ON SCIENCE. CURRENT NOTES OF DISCOVERY AND INVENTION. Spirit Slate-Writing — How Mysterious Sentences Aro Prepared in Advance— Tricks in All Trades and Especially Among Fakirs. FRAUD SLATE WRITINGS. Spiritualistic slate writing, if clev erly done, always makes a marked im pression on a magician's audience, be cause it utterly baffles their efforts to detect the trick. They see a small cab inet suspended above the stage by means of cords or ribbons. It has an open front, and is empty. The magi cian turns it around so that every part of it may be seen, and taps it in side and out with his wand, to show that it is hollow. On a stand near by he has a small easel, a common school slate, a bottle of India ink with a quill pen in it, and a few sheets of ordinary white writing paper. All these he passes around among the audience for examination. Then he fixes a sheet of the paper to the slate by means of wafers, places the slate on the easel, and the easel in the cabinet, together with the bot tle of ink, the latter having the pen still in it. Having allowed the audience to see the articles thus arranged in the cabi net, he throws a large silk handker chief over it. Mysterious sounds are immediately heard, and the cabinet shakes as if some living thing had en tered it. When the sounds and the shaking cease, he removes the hand kerchief, showing an inscription writ ten in bold black letters on the paper, and the pen, not in the ink bottle, but lying on the bottom of the cabinet. He then removes the paper from the slate and passes it around for exam ination, when the writing is imme diately recognized as having been done with India ink. The explanation of the trick is sim ple. The writing was done in advance by the performer, the fluid used being a solution of sulphuric acid of the pur est quality. To make the solution 50 drops of the concentrated acid are added to one ounce of filtered water. Writing done with this solution is in visible until exposed to heat; when so exposed it comes out perfectly black, looking exactly like dried India ink. The heat is applied by means of an electric current running over wire with which the slate is wound. The cords by which the cabinet is suspended con ceal copper wires, which conduct the current to the slate. Black silk threads, suitably attached, enable the perform er to make the sounds in the cabinet, to cause the cabinet to shake and to jerk the pen out of the ink bottle. Several sheets of paper are prepared in advance, pach with a different in scription, the performer telling one in scription from the other by secretly marked pin pricks. AUTOMATIC VIOLIN IS PERFECTED IN THE EAST. In this age of automatons it is not surprising to find automatically oper ated musical instruments. Everyone has heard the self-playing piano and musical box, and soon everyone is likely to hear an automatic stringed instrument, very similar to a violin, for a Massachusetts inventor has just devised an instrument of this kind. The component parts of this novel invention are strings, a belt bow, a frame and pneumatic devices, by means of which the bow is enabled to travel over the strings in whatever 2^3SE3EBBS L 3 \ THE AUTOMATIC VIOLIN, direction may be desired. These de vices are connected with a lever, which is controlled by a progressively moving actuator, and the position of which may be varied to suit the move ment of the bow. On the neck of the instrument there are also two inde pendent finger-bearing strips, In which are movable rods. Music of any kind, it is claimed, can be played on this mechanical violin, which, furthermore, is so constructed ,that It will last a long time and, if properly used, will not readily get out of order. AMERICANS AS INVENTORS. The United States grants 25,000 pat ents each year, or nearly as many as all the rest of the world. England grants 8,000" a year, France and Ger many each about 7,000, while Canada, Australia, Austria, Italy and Russia about half as many each. An interest ing fact is that more patents are granted in proportion to the applica tions than ever before in this history of the Patent office, showing that me chanical genius is not chasing as many rainbows as, formerly. American in ventive genius is shown in all lines of invention, but succeeds especially in machinery for manufacturing, trans portation and labor saving. Europe and the Orient have begun to find American industry very useful and necessary to them. HELPS VIOLINISTS. Young people who are learning the violin will be interested to know that a device has just been invented which is likely to prove of much service to them. It is in the form of a support for the arm, and it is asserted that by its means the instrument can be al ways held in an absolutely correct po sition. The inventor is a distinguished vio V THE ARM REST. linist and the device is indorsed by Dr. Laborde, a Paris physician, who thinks so highly of it that he spoke in its favor a few days ago before the French Academy of Medicine. The sup port consists of a semi-circle which enfolds the lower part of arm a little above the elbow, and which is con nected .with a belt that can be length ened or shortened according to the size of the arm. Its main usefulness lies in the fact that it prevents muscular fatigue, keeps the shoulder in a prop er position and finally gives the arm that power over the instrument which it must have in oraer to produce the best effects. Dr. Laborde has thoroughly tested it, and he maintains that young vio lin players who use it will learn more quickly and more easily than those who do not use It. THE PANSY FAMILY. There is a funny old story about the pansy which many children know, but many, again do not. The pansy has five petals and five sepals. In all pan sies two of the petals are of plain color and three are gay with stripes and spots of bright color. The two plain petals have but one sepal between them, while the two smallest, or the gay, petals, have a sepal each, and the one large petal has two sepals. As the story goes, the pansy repre sents a family—a mother, two daugh ters and twc step-daughters. The mother is very cross and cruel to her stepdaughters, obliges them both to sit on one chair and wear homely dresses, while her daughters have a chair and very gay dresses indeed. But why doesn't the father object to such treatment of his daughters? The ques tion is, can you find the father? He is at home. Oh, yes. But you will have to tear the house down, taking out the wife and children, to find him. He is a little bit of a man, with a white wrapper on and a night cap. But, poor man, he is sick, and, if you look close ly, you will find that he sits with his hands on his knees, and a look of des pair on his face and his feet in a tub of hot water. RAINED SNAILS AND TOADS. Saratoga, N. Y., and vicinity had an experience the other night, the like of which even the oldest inhabitant can not remember. It was a precipitation of small toads and snails, the visita tion occurring principally between 9 and 11 o'clock. A rainstorm prevailed during the most of the afternoon and increased greatly after nightfall. Shortly after 9 o'clock, what ap peared to be hailstones rattled to earth, but on examination they proved to be snails in their shells, many of which were'gathered by the astonished people. The snails were almost im mediately followed from the sky by small toads, averging from one-half to three-quarters of an inch in length. While the heaviest precipitation of toads and snails was after 9 o'clock, there are many who say that a num ber fell in the afternoon etorm. From what section the storm scooped up the toads and snails that were dropped on Saratoga soil no one seems to know. The fire losses in the United States in 1900 were $161,000,000, as against $153,000,000 for 1899. DAIRY AND POULTRY. INTERESTING CHAPTERS FOR OUR RURAL READERS. How Successful Farmers Operate This Department of the Farm—A Few Hints as to the Care of Live Stock and Poultry. A Swiss Condensing: Factory. Some interesting particulars are given by Mr. F. C. Harrison, bacteriol ogist to the Guelph Experiment Sta tion, in a description published by him of the great condensed milk business of Henri Nestle and Co., carried on by them at Vevey, Switzerland, and else where. The article says: The milk suppiy is drawn from over 250 villages, but the firm does not buy from indi vidual farmers. When the peasants wish to do business with the company they form into a co-operative society, and appoint one of their number as manager. They then sign an agree ment which binds them to feed certain foods to their cattle, to keep their sheds and utensils clean, and to do many other things for the good of the milk. The manager arranges the terms, settles difficulties between the com munity and the company, and exercises a general surveillance over his society. The Nestle company have twenty-five inspectors, each with a horse and rig, whose duty is to drive continually from village to village, seeing that all is right and in good order. The inspec tor is always drawn from a remote vil lage, has no association with the vil lages he calls at, and is selected for his vigilance and experience. The company also have their own veter inary surgeons, whose duty is to ex amine all milking utensils, and see that they are scrupulously clean, also that the byres are clean, well ventilated, and drained. The cows' diet is confined to hay and grass, and the inspector must see that no forcing foods, like oil cake, are used. Milk is transported in cans to the factory, and is there care fully weighed, sampled, and tested every day, to ensure that all cream is present. The contents of all cans are then turned into a huge vat, where the milk remains until required for boiling. It is then run into a copper boiler and carefully scalded. Syrup cooked in an other boiler to the right temperature and consistency is added, and the two are then mixed together. Next the milk is pumped into the condensers, and there condensed within a vacuum. The condition of the contents is ascer tained by means of a tube attachment, which is rotated into the interior of the chamber near the bottom and drawn out with a sample for examination. Condensation completed, the hot fluid is run out into cans to cool. To give an idea of the immense size of the Nestle factories it is sufficient to say that they daily handle 26,000 gallons of fresh milk, the production of 15,000 cows. Methods of Preserving E çrs. Doubtless some of our readers are interested in the question of preserv ing eggs. For such we publish the fol lowing from the London Rural World: The method most commonly in use is as follows: The eggs are placed in a large vessel or tub, holding large or small quantities, as the case may be, and these are all piled up, one on the top of the other. A preparation composed of a mixture of five gallons of water with one gallon of fine slaked lime, to which about a gallon of salt has been added, is made, an'l when the water has dissolved as much lime as it can, it is poured over the eggs until thev are entirely covered, keeping back any lime that may be at the bottom which has not been dissolved. The eggs may be kept in this manner for a very long period, but one drawback to this sys tem is that the shells of the eggs be come so brittle that they break with the slightest touch. It is necessary to keep adding a little lime from time to time, otherwise the preparation wil lose its effect, and the eggs will noi be in a very good state when the tinu comes for them to be taken out. Whei the eggs are wanted for use, they an talcen out of the solution and wipec dry, but they should be used as soo' after as possible, as they do not keei> very long. It may here be said, and this applies to all methods of preserv ing eggs, that it is absolutely essential that the eggs shall be put down quite fresh—if possible, the same day as laid —otherwise they will not preserve nearly as well. Another method adopted is that of placing the eggs in salt. This keep-, the eggs in splendid condition, bui there is a slight taste given to them, but it is not by any means disagree able. The salt absorbs a little mois ture from the interior of the egg, henct the inside becomes rather loose, and as there is a rattle when shaken, it gives one the idea that the egg is stale Another method in common use in some parts of the country is that ol making a mixture of sulphur and lamp black. The eggs are placed into a box with a small hole in one side, and the mixture referred to is put upon a saucer and lit inside the box. The eggs are by this means entirely cov ered over with a covering of black; and it is claimed for this system that the eggs can be kept for any length of time, and always be quite fresh and sweet. Whether this is a good method or not, can best be judged by the read ers. Personally, we do not recommend it, as the eggs being quite black would not increase their market value—rather the reverse. There are other systems adopted in various parts, but the ones that we have given are the chief English ones. There is another by which It is claimed eggs can be kept fresh for a long time, and that is by dipping them into wax or paraffine; but this is a tedious meth od, and one that involves much time and labor. The very best way of preserving eggs is by freezing them, and this is the only way, we think, by which eggs can be kept quite fresh and good. Of course there are very few poultry keepers who are able to do this as very few possess a freezing chamber, and are thU3 able to freeze their eggs. For this reason we have put it last, as to the ordinary poultry keeper it is quite useless. Too much importance cannot be at tached to having the eggs perfectly fresh when they are put down, and un less they are in this state they will never keep. No egg should be put down that is more than twenty-four hours old, and even less than this is advisable. As to whether fertile or infertile eggs are the better for preserving, it is a difficult matter to determine. We think—and several experiments that have been made go to prove it—that the infertile ones are the most suit able. Sheep In Orchards. I agree that when a pig gets an apple containing a worm there is no danger that the ^vorm will cause any damage to the future apple crop. But as an insect destroyer the pig is nowhere with the sheep. The trouble with the pig is that it is too much like a man; when it lies down and goes to sleep it is oblivious of all its surroundings. It sleeps just as soundly and snores just as loud as its human cousin, and when an apple drops it doesn't hear it or go for it until its sleep is out. The instinct of the worm teaches it to get out of the apple as quickly as possible after it drops. I have stood and watched an apple after it struck the ground, and seen the worm come hust ling out in a hurry and go for some se cure place, and before the pig gets the apple the worm is in some safe hiding place. Not so with the sheep; they never sleep so soundly but they will hear an apple falling rods away, and they are up and there before the worm can get out, and that worm is travel ing to the bourn whence no worm ever comes back to curse the apple grower. Yes, pigs are good, but sheep are a hundred times better.—Rural New Yorker. To what extent does feed affect the individuality of a cow? This is a question that has yet to be answered, so far as conclusive experiments are concerned. It is doubtless true that feed is constantly changing the charac teristics of animals, but we do not know how rapidly the changes takf place, nor do we know Just the effect each food has. To a certain extent we are feeding in the dark. The Maryland experiment station has been feeding a herd of common cows for several years and noting the effect of proper feed ing on individuality. C. F. Doane, who reports on the results, says: "No very material results could be noticed the first year from the extra feed and care the herd received, but through subsequent years there seems to be a steady improvement. Judging from the records of these cows, it is a ques tion if the quality of a dairy cow does not depend almost as much on the feeding as on the breeding. It is also a question if cows that have a more or less pronounced beef tendency, or, at least, would not be called good ma terial from which to build up a dairy herd, cannot, with proper management, be developed into profitable dairy cows." This is a view of the matter that will not strike some of our inves tigators very favorably. It has against t the generally accepted truth that we lave now so many good dairy cows that It will hardly pay to spend time, feed and effort in an attempt to reverse a tendency already strongly developed in a direction opposite to that of milk production. Harvey Johnson of Iowa says: When our litters are of sufficient age to turn out we usually put two and sometimes three litters together in a pasture where there is a good warm and dry building and plenty of good grass. Near where the sows feed is a small enclosure with a low trough in it, and by a little persuasion and some tempt ing bits of food we expect to have the pigs feeding nicely at three to four weeks of age. The feed is increased as their capacity for handling it is in creased, but we are careful to under feed rather than overfeed—feeding no more at any time than they will eat clean. We allow them to run with the dams till they wean them, unless we wish to breed the sows again.
