Ventilated Costumes for Use in the Unlimited Heat — But How Can You 

 Arctic Circle Use It? 



EVEN in the Arctic Circle, there is dan- 

 ger of perspiring when the tempera- 

 ture is endeavoring to drop through the 

 thermometer. The colder the weather, 

 the greater the danger. Swathed in 

 heavy furs, as the white man goes, he may 



get overheated ^ 



while traveling. 

 When he stops to 

 make camp, he will 

 freeze in a very 

 short time. Ter- 

 rible suffering is 

 the result. 



The Eskimo has 

 solved the problem 

 of how to keep 

 warm without per- 

 spiring, in a simple 

 but original man- 

 ner. Instead of 

 covering himself 

 completely with 

 Arctic furs, he 

 leaves some portion 

 of his body partly 

 uncovered. This 

 allows the air to 

 penetrate between 

 his heavy furs and 

 his body and ven- 

 tilates his costume. 



If the Eskimo 

 woman from East 

 Greenland, shown 

 in the illustration, 

 remains out of doors 

 for some time in 

 the most severe 

 part of the year, 



she covers the middle of the open space 

 above her boots with belts of foxtails, but 

 adjusted in such a way that she will get 

 the necessary air ventilation. 



In North Greenland, the men's suits 

 have an open space around the waist, be- 

 tween the coat and trousers, while the 

 Greenland tribes in Northern Canada 

 wear wide, short trousers, which expose 

 the knee and part of the leg to the cold air. 

 The leg may be inirtially protected when 

 walking or working. I wore this costume 

 myself when on my Arctic exploring 

 expeditions. — Chkistian Leden.

HY should we enrich the coal barons 



This Eskimo woman wears a costume in 

 which there is an open space for ventila- 

 tion between the boots and the trousers 



warm, though in summer we have such a 

 superabundance of heat that we must pay 

 tribute to the ice kings in order to be 

 comfortable? It is exasperating to think 

 of the warmth that 

 ^ goes to waste in 

 the dog days. How 

 soon will mankind 

 discover a cheap 

 method of bottling 

 it up for use when 

 wanted? Equally 

 tantalizing is the 

 thought of the 

 enormous amount 

 of heat in the in- 

 terior of the earth, 

 which, as far as we 

 know, is of no use 

 to anybody. Why 

 can we not tap it, 

 for use both as 

 heat and power? 

 Attempts have 

 been made by en- 

 gineers to harness 

 hot springs, but 

 the power thus 

 produced was in- 

 significant. It has 

 been suggested 

 that the continuous 

 streams of lava 

 which flow to the 

 sea at Stromboli, 

 in the Mediterra- 

 nean, might in 

 some way be made 

 to do useful work. Sir Charles Parsons, 

 in an address before the British Associa- 

 tion for the Advancement of Science, once 

 discussed the feasibility of sinking a bore 

 hole 12 miles deep, at which the tempera- 

 ture of the rock would probably be more 

 than 270 degrees Fahrenheit, and down 

 which water would be pumped to return 

 to the earth's surface at a high tempera- 

 ture. Such a boring would cost millions 

 of dollars, if it could be made at all. 



It would surely be sinking money "in a 

 hole in the ground!" But it won't be 

 done for some davs vet.
