They bought a .staggering tonnage of prom- , tees few of which could ever be kept -52,000 tons of cleansing cream, 27,- 000 tons of akin lotion, 20,000 tons of ,complexion soap. To find out what the women are getting for their money, 1 consulted .0; . promisee ekin specialists, and had a number of widely used preparations .subjected to laboratory tests. The results 'show that the advertisers' version of skin, 'health bears as much relation to facts as the green cheese fable does' to the moon. The 'dermatologists are not amused by the cosmetic comedy. They- con- sider most cosmetics harmless, but extravagantly overpriced and with corms exceptions incapable ef the miracles claimed for thein. They ob- jeot to the misconceptions created by the imagination of sales promotion experts—such as the deliberate fic- tion tihat the feminine skin is a deli- cate tissue winch. must' be oiled and fed if it is to remain attractive.

But—contrary to t1e ads it won't take noarislunent. It can b fed only from within; its appearance sallow !or glowing, reflects the indi- viduates tin:ten:sal health. And they brand as treeless the hundreds of ereams or lotions which purport to feed vitamins or other "valuable" substances into the skin. Dr. Howard Fox, Emeritus Profes- sor of Dermatology of the New York University School of 'Medicine, main- tains that cosmetic inansufectueers have erected a fiction worth millions upon the little ward "pore." Count- less women have been led to buy "astringents" in the belief that the pares "open and shut like the mouth of a fish." Which of course islet true —"the pores cannot be closed by any method." Of "muscle oils" and "wrinkle removers" Dr. Fax says: "You are given to understand, that you can oil up the voluntary muscles of the skin as if you had a tiny oil can. No preparatiou applied to the skin 'has any effect on the mescles of the skin.. Nor will any crewM do away with wrinkles, which are caus- ed by disappearance of the subcutan- eous fat and a lessening of the ten- sionof the skin." si Thougar millions may be wasted on some cosmetics, others are undeniab- ly as essential to the weledeeseed wo- man as her silly hats and her high - heeled aloes. She may not get the health of skin she paid for, but from the adroit use of rouge, powder a.ndi lipstick she gets peace of minel, and a "lift" when she looks in the mir- ror. So the dermatologists gladly an cord to woman these adornments. But they add, she is being overcharg- ed for some very simple compounds. This is borne out by the tests made in my anvestigetion. Cosmetics in general use were purchased from five-and-ten, drug and department stores, as well as from a few beauty Minns Theee typical, same were analyzed by a weleknown laboratory in New York. The findings, snow lit- tle relation between the quality of cosmetics and their price The chief item in a woman's beau- ty kit is face pawn Good face powder should be nigisy to spread, should adhere well, a nate 'should cover a wide area, and it should not readily absorb moisture. Tested for ale:se and other qualiti.es, a medium- priced brand at 47 cents an Ounce proved best. The most expensive was certainly no better, though it cost 61 cents an ounce. It contained starch which caused it to abseil) moisture and become lumpy. Besides, cereal's are individuals are allergic to starch. There was little to choose 'between the cheapest brand at 18 cents and the atigbent-priced at 61. Four well known, brands of lique- fying cleansing 'cream turned out to be physicany and cheinisally almost identical. Yet they ranged in price 'from 15 to 58 cents an ounee. Ex- cept for the difference in perfume, they might all have come from the same hatch. Possibly they man- ufacturers of paraffin and petrolatum blends turn the basic -cream out by the ton, ready for peremning and packaging under any trade name. The effect of sawn creams is largely me- ohsanical anyway;' -•they lubricate the dirt so it can be wiped off. Ttests of lipstick were for melting point (which should not be too far above body temperature); fair ease of removal with dry cloth and with soap and water, permanency of fa- bric stail after- boiling in soap and water, and uniformity of streak un- der the mdcnoscope. Of the four lip- sticks tested, brand B, at a little ov- er 'a dollar an ounce, performed quite as well as brand C, at oyer $7.

They may be divided inte three broad class- ifications: mechanical, toxic a n, d functionet. Manay headlaches must be placed in two OT all of the groups. Mechanical headaches are produc- ed by diseases of, or damage to, the bead itself. The headache whrich ac- conipanies your cold, for example, is tprobably due to a swelling of the mucous membrane lining the nasal chamber, which closes the narrow passageways to the sinuses — those bony cavities in the front of the ekull. A partial vacuum results which sucks on the mucous1enaboane of the sin- uses, stretching ,13, e nerves and caus- ing a .dull pain. Physicians relieve this condition. with solutions wbich shrink the membranes and permitair to enter. Also classified as mechan- ical are eye headaches, which may be caused by even a slight ' error of refraction. Close - work and reading in bad Light are contributing factors. A suitable pair of glasses is of course the remedy. Major headaches of the mechanical, type are so painful that they may rouse the sufferer from sound slum- ber. Such headaches may indicate concussion, tumor ar abscess of the brain, diseases of the cranial blood vessels, or Meningitis.' To understand the anatomy of headache, some knowledge of the cranium is necessary. The skull is filled so compactly with brain and cerebrospinal fluid that even a slight rise or fall in pressure of this fluid can produce pain. The outer eover- ing of the brain, known a.s the dura, Is a tounh, white membrane interlac- ed with nerves, The dura can be cut with a surgeon's knife without pain, but is extremely sensitive to stretching. This stretching process is important in the second classifica- tion of headachesn-those due to toxic What is an adventure Not neces- sarily a thrilling escape from (teeth, a holdup on a dark road at midnight There are others. The newsbady, for instance, who runs after you when you have over- paid him a penny; the lark by the roadside of a spring 'morning; the hilltop where life seems seddenly fresh and worth while again; the fire - vide and a good friend -when the bliz- zard howls witthout; tee limping dog, the sobbing child, the merry quire the chance acquaintance. These and a thousand other bitsof living ane all ad -ventures, and those who meet them with the ad'venturer's heart will catch the extra pungency of their flavor till the day of their death. * * * I know a fisherman in a small vil- lage on the Meese coast whose habit of going places close to home makes his life a constant excitement.

Toxis headaches are produced by poisons from outside the body—alco- hol, gases, drugs, tobacco—or by ;poisons manufactured within the bo- dy. In kidney ailments, constipation and all diseases accompanied by fev- er, poisons are generated which may alter the circulation in the biped ves- sels of the brain, or affect the nutri- tion of cranial nerves. The webwork of blood vessels in the brain cover- ing may expand, the dura is stretch- ed, and pain results. Sometimes the headache is caused by contraction of the small blood vessels' in the dura, as in the morning headaohe of the man who Ins smoked too much the night before. An obscure poison in tobacco impoverishes the tiny blood vessels Of the brain. But the caffein in a cup Of breakfast coffee dilates the collapsed, bloods vessels and clears away the headache. The functionail headache, to Which no organic cause can be assigned, is a catchall for many of the puzzling debilities which the' medical profes- sion cannot yet eintirely explain. Headaches produced by higib or low blood pressure, unemia, ,excessive mental strain and menstruation ;be- long in this class. Also included is migraine, a mysterious periodic oom- and it is a free 'show. Increase of diffi c u 1 ties as d responsibilities streegthens arid enriches the mind, and adds to the variety of life.

What I think they mean le that they "Couldn't stand it" if they •haann the power of dentehing thembelves front a painful situation, :and ,centenenating it as drama.

It is literally true that you may have a headache because you 'have unconsciously hat- ed your Unctle Elmer for 20 years. No one knows the basic mechanical explanation; the most careful exam- ination equally discloses no physiolo- gical abnormality. Such a hea,dacthe sometimes encompasses the cranium in a tight band, or fits like a helmet over the front of the head. Depres- sion, werrry, unbappiness, repressed and IIIINkl"rttly impulses can also ex- press themselves in headaches. The therapy? Hobby, a captivating inter- est, or, best of all, an acceptable out- let for therepressed impulses. Fortunately the least dangerous headaches are the commonest. One large hospital Intel causes in this order of frequency: fatigue, hunger (both of whet affect the 'nutrition of the cranial nerves), constipation, in- t:lig:est:km alcohol., e-yestrain., infec- tious disease (with their attentdant fevers), men:sensation, nervous disor- ders, kidney disease, nose abnormali- ties, sinus infection, neuralgia and mi- graine. •Occ.asional headaches of low intens- ity may be of no important at all, but chronic headache is something else again. The indiividualto habitually doses his headache with self -prescrib- ed remedies is downright stupid. ConstipatIon is an'.acc om p any i ng symptom) of many Maladies; a purge may relieve the constipation and not cure the headache. It 'is unwise, in any case, to rely entirely on laxa- tives. Painkillers effectively relieve discomfort, but not all of them are harmless. Acetanilid, a common ne- gredient of headache remedies, de- presses the heart and is a poison if taken in sufficient quantities. The phenobarbitals should be used only under medical, supery sio n. Rather than seek relief with commercial pre- paraticms, try one of the following remedies first: For that en no at lee -day dull th,rob, wth•ich may be caused by a combina- tion of fatigue, aungerf and over- stress, take a small quantity of light food, loosen your clothing and lie down in a darkened room for half an hour. A cold come:dem over the eyes and forehead is often effective. A brisk walk, an' invigorating shower may speed up your circulation euffici- eautly to relieve the headache. If the areadaohe is due mainly to congestion of circulation in the head, a hot foot bans may draw the blood away from the congested regime and relieve the heapclaiche without •drugs. Happily, the outlook for relief from chronic headaches le growing more hopeful. In such grave maladies as brain tumor and meningitis there has been a great advance in eureical, teen- ue. Medicine has devised means for reducing intracranial preseure,, for dealing with germ infection and far quieting pain while the source is hunted.

IMO, back steam. Three things must be engine eered In the process: water, fuel and air. For everynon of coal that burner in the furnace, 10 tons of water must be supplied in the boiler, and 12 tone of air must be sucked into the come bus•trian chamber. Incidentally, thir- teen tons of combustion gases go up the stack. In a big steam plainathese items assume nage proportions. That Hudson Avenue Station in Brooklyn oonstmues an. average of 3,750 tons of coal !daily. To cool its steam at tire end of the cycle, this station pumps) 3,600,000 tons of East River water through ler condensers, a daily pump - age wen in excess of the daily water supply of New York City. There are now 10 steam power plants along this short stream, an using its water te cool their condensers, and in cense:- quence the average temperature of the East River has been „raised 16 de- grees in the last 36 years. In even the coldest winter it does not freeze over. The fuel is mostly pulverized coal, blown into the furnace through spe- cial burners designed to promote quick- combustion. Some burners spray their powdered coal downward and the Week mist catolies fire in raid -air, generating temperatures as high as 3,000 degrees. The heat generated: depend' not only on the state of the coalnbut al- so on tbe temperature of , tbe air which 'supplies bhp necessary oxygen.

Never has it been more •sof—more useful in the service of tuan—ehan, in this fourth decade of the 20tb, century. By over- waelmaing odds, not water power but steam is shills the prime mover of in- dustry. In the United States, more than 60 per, cent of the central, elec- tric power stations are actuated by steam, and 90 per cent of the indi- vidual industrial power plants.

By thin means, heat which ordinarily would escape is used to raise the tempera- ture of the air to 400 or 500 degree that when it pastes on to the furnace, it leaps to its union with the falling partioles of coal in the thousandth &I' -a second. . Also surrounding the flues are other hollow wane and pipes for the Pre- heating of the water before its ad- mission to the boiler.' The hotter the water and air, and the finer the part- icleof coal, the more rapid is the generation of steam. Since turbines turn steam into pow- er at high velocities and in enormous quantities with the minimum demand upon supervision, they have almost supplanted the familiar reciprocating engine (with its back -and -forth mo- tion) in plants Where mass produce non of power is eseential. The tur- bine is edging a way even into small plants. The layman's thought of steam ie associated with water, but engineers' are experimenting with other liquids which boil nt other temperatures. For example, in boilers at Lhe General El- ectric plant in Sottenectady, these are 155 tons of mercury, costing about $200,000. This fluid metal is used ov- er and over again in tbe hermetically: nealed system completing its cycle. from boiler to condenser and back again hundreds -of times each min- ute. To heat it to 677 degrees (wae ter boils at 212 deerees), The vapor from the boiling mercury is first us- ed to turn a turbine, then conducted to a second boiler where its heat ev- aporates water to steam, ,and the steam delves another turbine. Thus one heating of the mercury causes two turbines to turn. But tbe story of steam power's re- cent advance is primarily a story of steam from water, achieved by ine creasing temperentrees and mounting pressures. Few of the present attairn ments were feasible fifteen years ago. Ircin. glows red at 750 degrees and In 1921 a nailer that delivered steam at this temperature waserated a super- power plant. Today 900 degrees and above is established practice, due to the introduction of new alloys. The tough metals lately born of the meet- ing of steel with chromium, molybde- num, nickel and tungsten will endure the high temperatures and 'resist the high pressures. And yet, with all the brilliant ad- vances in fuel' eoonomy, the wastes, are still colaseal. Moat of the energy of burning coal is wasted: beat effici- enty in the most capable plants to- day i Bony 25 to 35 per cent, where- as the water Wheels in the hydro- electric plants are 90 per -cent effici- ent., Since steam even with its mese ent low 'efficiency, can compete Suc- cessfully with water power, and since it contains so many more wild horses of ,potential power, is it strange that it continues to dazzle the imagime- rtion of inventors and industrialists?
