The new X-ray apparatus takes an electric current at 600,000 volts through the biggest X-ray tube us- ed for industrial radiography in North America. MAKING GLASS INVISIBLE Discovery of a coating that makes glass, invisible is announced by Dr. Katharine B, Blodgett, not- ed woman Scientist in Scbenectedy, N.Y. The glass never reflects light from any angle whatever. Clock, Alai face and show case glass and windows appear not to exist. An in- credibly thin film on both surfaces o8 glass is the secret of this scien- tific mirale. The film is about 41 1,000,000ths of an inch, or one- quarter the wave length of light, in thickness. COBRA VENOM A TONIC Cobra venom is a mental tonic. The venom is injected into the muscles, once a day or less. Its ef- fects are slower than morphine, but last longer and are not habit -form - trig. Direct mental stimulation is also shown, that is, not merely psychic effects due to relief from pain. In addition two other improved facul- ties were noted: Wider angle vis- ion and better muscular co-ordina- tion. GAS QUICKLY 'LIQ'UEFIED Professor Peter Kapitza, former director of the Royal Society's Mond Laboratory at Cambridge, now head of the Soviet Govern- ment's new laboratory at Moscow, bas perfected a new method of liq- uefying gases. It is announced that this discovery will have great scien- tific and industrial importance. Only a few details have been made known, but a vital part of the invention is said to be a turbine of completely original design. It is no larger than a match -box and weighs about half a pound, but has far greater efficiency than the mach- ines heretofore used. A woman entered the butcher's shop and asked him to cut off ten pounds of beef. He did so. "Shall I send it, madam?" he asked. "Oh, no, thanks," she replied. "I've been reducing and have lost ten pounds, and I wanted to see what it looked like." There was an old man of Colquhoun Who built an enormous balquhoun. To his utter surprise It rose to the skies And nearly bumped into the "mqulioun. The golf novice had not made much progress, but he was a man of iron •determination. "I'll move heaven -and earth to play this game properly," he said,, as for the fifth 'stroke in succes- sion he pulled up the turf. The caddie spilled. "Well," he -said, ""yo"u haven't much farther -lo go.. You've ,only heaven to move :'sow." "Have you much room in your new flat?" "Heavens, he.

He came to one which de- clared: "Not dead, but sleeping After contemplating the phrase for a moment, and scratching his head, the Negro exclaimed: "lie sure ain't ifoolin' no one body but Ilisself." "What would the girl a to- day do if she suddenly found berseif in the Middle Ages?" wonders an essayist. Go on pretending that she was only about twentjr-one. "Hair cut, sir?" inquired a bar- ber of a customer whose head ira;y almost bereft of hair. "No/' was the sarcastic retort. psi want it done up in 'a bun and fattened with a pink ribbon."

New High -Altitude Land Plane Passes First Tests Officially known as model -307, Boeing Aircraft Company's 33 -passenger "stratoliner" is shown after being wheeled out into the open at Seattle, Wash., for the first time to be prepared for a series of engine tests. The silver four -engined craft is 74 -feet long with a 107 foot wing spread, weighs 42,000 pounds and is designed to cruise at 300 -miles per hour at a sub -stratosphere altitude of 20,000 feet. Two super -chargers maintain a cabin pressure greater than that of the rarified air outside at that altitude, allowing the passengers perfect breathing comfort at all times. The dirigible -like fuselage is perfectly streamlined with- out a break even for the windows of the control compartment. HOW GM I? BY ANNE ASHLEY Q.—How can I detect a leak in a gas pipe? A.—At the point where a leak in the gas pipe is suspected, ap- ply a paste of soap and water. if there is a leak, bubbles will ap- pear. Never use matches or a flame of any Lind when looking for a gas leak. Q.—How can I remove hot pans from the oven easily and without danger of burning the hands? A.—A small, short, tin shovel can be purchased for about ten cents. Flatten out the sides of the shovel and it will make an excel- lent utensil for removing hot pans from the oven. Q.—What is a home remedy for neuralgia? A.—The eating of a good quan- tity of celery is often an effective remedy. Q.—Flow can I add` just the right amount of stiffening to or- gandie -:trimmings, such as, collar and cuff sets? A. -Try dipping them into wat- er in which rice has been boiled. Q.—How can I give fingernail polish a higher gloss? A.—When polishing the finger- nails, put on the pink or red pol- ish, but leave the tips uncovered, and whiten underneath. Then go over the whole fingernail with a coat of colorless polish. It will give a higher gloss, a neater fin- ish, and will last longer. Enplish Know Little Abut Empire Life Canadian Woman Complains That People of England Are Ignorant of the Geography, Politics, Economics of The Countries in the Empire A. letter to the editor of the Daily Telegraph (Conservative) one of London's leading papers, from an unnamed Canadian woman who complained that the people of England know too little about the Empire drew an editorial admission from the newspaper last week that her allegation is well founded, The editorial foilows: ""There is still too much justifi- cation for the friendly remon- strance which a correspondent from Canada makes in our columns today that the English people do not know the ,countries of the Elm pire and they 'should. Characteristics of Nationhood '"She is not the only visitor from the Dominions who has found us ill-informed about their geography, their- politics. and economics, and— the worst defect of &l—about the distinctive. characteristics of their nationhood. "Our educational system is still guilty of neglect of the significance .66e the Empire. Fortunately, how- ever, there are now expanding ef- forts to send young people of all classes on Empire tours, and inter- changes aro arranged which may well progressively increase." When Knives Were Used For Eating Before the advent of table :forks, eating with one's knife was the vogue among society people. Before this it was quite proper to oat with one's fingers. The table knife came into general popularity some time after the seventeenth century and was the correct thing for eating as wen as for cutting. Flying Mail -Van A "flying mail -van" that picks up and delivers mail at 90' miles an hour is to start operation in Pennsylvania. Watching a demonstration of the new service post office officials saw a pilot cut down his plane's speed to 90 m.p.h. as he flew to- wards two 23 ft. poles linked with a rope. Attached to the rope was a dummy sack of mail. The pilot manoeuvred the 'plane downward, picked up the mail sack and drop- ped another. The route to be covered by the new "flying mail -van" includes 27 towns and cities. Important Year In ` 'story of Aviation Here Trans -Canada Airlines Are Ex- pected to Carry Passengers Early This Spring — Signifi- cance of 1939 In Transoc- eanic Flights The most important year in the history of the aviation industry in Toronto and Canada as a whole is indicated with the beginning of 1939. During 1938, tremendous strides were made in Canadian aviation and it is during 1939 that these steps are expected to bring the in- dustry in this country to a destina- tion that will be the culmination of much planning and effort. Experime.tts Completed Before the last leaf of 1939 has dropped from the calendar, great liners of the sky are expected to be shuttling back and /forth be- tween this country and Europe, winging passengers and mail across the Atlantic. The long process of experiment is practically complet- ed and the whims of wind and the weather above the restless Atlantic are now well known to the men who will pilot the air -giants on their long journeys. Groundwork Laid From present signs, it is indicat- ed that 1939 will be no more than nicely on its way before the big metal strips of Trans Canada Air lines will be opening their doors to passengers. The groundwork has been laid, beacons flash along the air routes, radio beams are at this moment beeping away across Can- ada's bushlaud, landing fields have been made ready and, last but not least, T. C. A. pilots have become familiar with their routes. World's Shortest Railway's Here Between Huntsville, Ont., and Lake of Bays — One ladle, Nar- row -Gauge Road — Closed for Winter Months tee and snow cover the North Muskoka lakes and the two din - key •engines and other rolling stock of the Huntsville and Lake of Bays Railway Company, the shortest rairoad in the world, are laid up in the roundhouse awaiting the opening of the 1939 naviga- tiot and tourist season. The automobile has wrought great changes in the transporta- tio:. picture of Ontario's play- ground. Passengers no longer travel in large number over the steep portage from Lake of Bays to Peninsula Lake. But the little train, once known as the "cork- screw limited," makes daily trips each summer over the one -mile, narrow-gauge road. Built In 1903 Built in 1908 at a cast of $40,- 000, the road winds around huge rocks and hills, skirts a small lake and climbs an elevation of 130 ft. in a half -mile from Peninsula Lake to Lake of Bays. It runs over an Indian trail that for 100 years was used by the Algonquin Indians in trading throughout the area. Modern Etiquette BY ROBERTA LEE 1.

Says New World Was "Civilized" Before Old One Scientist Claims Plants Were Domesticated and Cultivated In America Before Dawn of European Civilization Human civilization, as measured by agricultural development, is old- er in the "new world" than in the "old world," Dr. Donald D. Brand. the University of New Mexico, an- thropologist, contended this week. Evidence Found by Botanists "If the beginnings of agriculture mark the dawn of civilization, then evidence collected by botanists and anthropologists indicates an earlier civilization in the new world than in the old," he said; Dr. Brand said that "unlike the wheat, and most other domesticat- ed plants, maize (Indian corn) re- quires cultivation 'for its propaga- tion and scarcely an old world spe- cies of plant can compare with the maize, field pumpkins and kidney beans In the area of its spread at the time of Columbus." In Mexico and Central America ''The greater variety of squashes, maize, kidney beans, manioc, pota- toes and other .cultivated plants cannot be matched in Eurasia or in Africa." "The prehistoric; inhabitants of Mexico and Central America do- niestimeted more plants than the inhabitants of any comparable area in the world," he "said.

S. National Museum. The mud looks like ordinary muck, but really is made mostly of diatoms, microscopic marine animal shells which are pure sil- ica. Dr. Conger said he found this kind of mud in 64 lake bottoms and bogs in Northern Wisconsin. When the mud was dried and the organic matter burned off, the residue was commercially valuable "diatomecious earth." This earth is used for fine filters, such as sugars and fruits, for heat insula- tion, tile -making and many other purposes. Study of' the Wisconsin ^lakes, Mr. Conger said, shows that simi- lar diatomaceous muds will be found in lakes of Southern Canada as well as Minnesota, Michigan, New York and New England. Hydro System In Northland Will Be Extended With Help from Ottawa Government in Patricia District Hon: W. L. Houck, acting chair- man of the Ontario Hydro -Electric Power Commission, announced last week the Ontario Government had approved by order -in -council the construction of a new 113 -mile pow- er transmission line in the Pickle Lake district of Northern Ontario. Work For Unemployed The line is being built particular- ly to meet increasing requirements of the Pickle Crow and Central Pa- tricia gold mines. It will be exten- sion of a line being built from Earl Fails to supply power to the Uchi gold mines. Estimated cost is plac- ed at $937,000 and the line will be constructed to operate at 68,000 volts. The project will be undertaken under an agreement reached be- tween the Ontario government and the federal government in respect to aid of Northern Ontario unem- ployment. Federal government will contribute 50 percent. of labor costs and approximately 500 men will be engaged'in cutting the right-of-way for the line. 1938 Field Crops First Official Estimate PIaces Gross Value of Canadian Output of 6 Per Cent. Lower Than 1937 The first official estimate of the gross value of the principal field crops grown in Canada in 1933 is $527,149,000, which is $30,968,000 or 6 per cent. below the estimated value of the 1937 production, and $84,851,400 below that of 1936. The value of the 1936 harvest was the highest since 1930 when the value was $66,040,900. Low yields in 1937 and sharply reduced prices in 1938 have resulted in successive reduc- tions in value for the past two years, These estimates are subject to re- vision and do not represent cash in- come received from sales, but are gross values of farm production. Se- veral of the crops, such as mixed grains, turnips. and fodder corn, are almost n -holly utilized on the farms on which they were grown. While the 1938 wheat production is nearly double that of 1937, the average farm price is only 57 cents as compared with $1.02 in 1937. Thus the value of the crop is only about twelve million dollars great- er. Increases in the production of oats, barley and rye in 1938 failed to offset declines in prices and the combined value of these crops Is $35,694,000 less than in 1937. Tr ... pph g G es x 99 6Stlreamli ?e'd Canada's Oldest Business Has Been Transformed By Plane and Radio Canada's oldest business trap- ping—has been "streamlined through use of the aeroplane and wireless. The swift drama of mod- ern methods has replaced the pic- turesqueness of the canoe and the portage. The majority of the estimated 300 to 400 trappers operating in the Northwest Territories and remote Northern regions of British Colum- bia, Alberta and Saskatchewan now take full advantage of commercial aviation and widespread radio facil- ities of the Royal Canadian Corps. of Signals. To Civilization in Few Hours Each fall Edmonton commercial aviation firms carry north nearly 150 trappers, their dogs, canoes, traps and provisions. Throughout the winter aeroplanes call at the trappers' cabins or the nearest post. and freight the furs to market. In the spring the modern Coureur de Bois are whisked from the loneli- ness of their trap lines to civiliza- tion in a few hours. Besides eliminating many weeks on the frail to and from the trap- ping ground, the aeroplane en- ables trappers to locate new ground. quickly after old lines have been "trapper. out." After an X-ray revealed a stolen ring in his stomach, William Thompson, of Glasgow, Scotland, was sentenced to prison. lc "MAKE TRACKS FOR OGD NS!"
