Bronchitis la an Inflammation of the membrane lining the air-tubes In the lungs. It may t acute or chronic, and may vary through all degrees of ie-Terlty. ie-Terlty. from an unpleasant, although quite trivial, comrlaint to a rapidly fatal fa-tal illness. The gravity of acute bronchitis bron-chitis depends a great deal upon the age of the sufferer. In the very young and the aged It Is often a most serious malady, while in those of middle life It la seldom dangerous unless neglected, neglect-ed, and so allowed to become chronic. The most frequent cause of bronchitis bron-chitis Is "catching cold." that is. a general gen-eral or local chilling of the urfa e of the body. The cold usually starts in the none and throat and "works down," or the trouble may begin at once with cough and pain in the cheat. Acute bronchitis occurs also as an accompaniment ac-companiment of measli-s and other diseases, dis-eases, and sometimes is produced by the Inhalation of dust or Irritant rape ra-pe rs. The most prominent symptom of an acute "cold on the chest" Is enough. This Is caused by the secretion from the mucous membrane of the bronchial bron-chial tubes, a, id is accompanied by more or less expectoration. It may be Tery Incessant, occurring In repeated paroxysms, but is always temporarily relieved by the appearance of phlegm. Pain in the chest is another frequent symptom. Tula is felt behind the j Breast-bone In the center of the chest. I extending sometimes toward one, or both aides. It may be sharp at first, but is generally iull and of a compressive compres-sive character, as If some great band were squeezing the lungs. The secretion Is at first sticky and difficult to dislodge, but later becomes more fluid, yellower and Is easily expelled. ex-pelled. At the beginning. In severe cases, there may be some fever preceded pre-ceded by chilly sensations, but this does not last very long Acute bron hltls. like a cold In the head, will often cure Itself If the patient pa-tient will stay In a w ell-ventilated room with an equal temperature, and restrict re-strict his diet for a day or two, taking plenty of cool water to wah out the i system, the only medicine needed being I perhaps a mild laxative. If the cough la so painful aa to ("!,; for special treatment, among the best of domestic remedies is the old-fashioned flaxseed tea. A mustard plaster (not so strung as to blister) on the cheat Is aUj of service at the beginning begin-ning of a severe attack. If the cough persists, or the secretion becomes profuse. In spite of domestic remedies, more strictly medicinal treatment will be called for. In the caae of the very young or very old no temporizing Is safe, and the physician should be summoned at the outaet. It-La THE I.KASS AND Wl l l. Here la a woman's Invention for destroying de-stroying the grass and weeds which make many a railroad look nns ghtly, a patent for the apparatus having been granted to Sarah P. E. Erickson. a Kansai woman. Her idea is to treat the grass and weeds to a shower of salt water at frequent Intervals, which, she claim, will not only destroy all vegetable vege-table growths, but will also arrest the decomposition of the ties by their absorption ab-sorption of the brine. The apparatus which baa been designed for this treat- FAN FOR WINTER AND SUMMER, fan blades. Although but three coila ara shown, the inventor does not Intend In-tend to limit himself to this number, but may use more until the desired quantity of heat Is produced. The current cur-rent for the resistance colls la Introduced Intro-duced to the fan through the brushes and collector rings engaging the shaft, and If It Is desired to u?e the fan for cooling Instead of heating purposes the brushes are removed from the rings, when the fan will aid In the circulation circula-tion of the air without hem. ANKLfcTH or (0(ll()J. An intere.-ting account of how rickshaw-bearers In Natal make anklets for themselves out of empty cocoons is contributed to the Scientific American Amer-ican by Dr. L. O. Howard of the United States Department of Agriculture. Ha says: The writer recently received from Mr. Claude Fuller, tho government entomologist, of Natal, two interesting anklets formed of the cocoons of a large bombycld moth. The natives col-I'-ct the cocoons after the moth has leaned from them, put one or mnre small stone Into each, and sew them upon a broad strip of monkey skin, side by side, so as to cover the surface of the skin. The cocoons are tough and dry. and the stones within them rattle in a most delightful way. The use of those ankle rattles baa become be-come quite general In Natal since the Introduction of the rickshaw from China and India. The rick-shaw-bear-ers wear the ankleta very generally, and ihe sound of their rattle on the streeta Is almost as familiar aa the sound of sleigh-bells In a New England Eng-land town in winter. This Invention is not confined to routheast Africa. Dr. Walter Hough, of the United States National Museum, haa shown me rattling anklets from Mexico which are made in a somewhat similar way of the cocoons of another bombycld moth. In this case many cocoons are strung together on a string, and several rows are tied around the ankle. Each cocoon has been opened for the purpose or Inserting Insert-ing the atoneg. Doctor Hough also tells me of a much larger cocoon from India, which is mounted singly at the end of a stick to be carried In the hand. This cocoon also is made into a rattle.
