The Open-Air Barber Shop Where the A Wounded Man Can Dress His Own 

 Prices Fit a Beggar's Pocket Wounds with This Bandage 



IN Paramaribo, capital of Dutch Guiana, r T*HE rolled bandage is in great demand. 

 South America, are many East Indian A Not only in the hospitals and in the 

 coolies who have been imported under a equipment of the doctors and nurses on the 

 system of indenture in such numbers battlefields, but also in the comfort 



that they comprise one third of the 

 entire population. 



Now, since through some 

 tenet of their unfathomable 

 religion, the wearing of a 

 beard is not permitted ex 

 cept by the very aged or 

 by dignitaries, the coolie 

 must needs shave con- 

 tinually. Even the 

 tramps and beggars must 

 keep their faces clean- 

 shaven and their hair 

 cropped. Naturally the 

 proprietors of our bar- 

 ber shops do not care to 

 accommodate the class of 

 patron seen in the photo- 

 graph below. But the 

 itinerant barber has no 

 such prejudice. He has 

 no overhead expense to 

 meet, such as would be 

 entailed by a shop, so 

 that his prices can suit even the beggars 



The bandage has 

 an adhesive plaster 

 on one end which 

 sticks to the skin. 

 It is then unwound 

 and wrapped 



kits of the soldiers it is found — or 

 should be. The one illustrated 

 is an improvement on that in 

 ordinary use. Its chief fea- 

 ture is an outer end which is 

 adhesive and which enables 

 a wounded man to apply 

 l the bandage himself if 

 necessary. 



The ends of the roll 

 i \ are coated with wax, 

 - which keeps the ma- 

 terial from unrolling, 

 even if the bandage is 

 dropped. This also 

 prevents it from 

 getting soiled 

 when carried in the 

 pockets. To apply 

 the bandage, a 

 man injured in the 

 left arm, for instance, 

 takes the package in 

 his right hand, and the 

 loop, shown in the photograph, in his teeth. 



The traveling barber locates his shop wherever 

 there is a group of squatting coolies to be shaved 



Olive Oil Can Be Utilized to 

 Prevent Fog at Sea 



OIL, though long known to be 

 effective in calming a sea, has 

 only recently been proved of value 

 in preventing fog. Air is prevented 

 from coming in direct contact with 

 water which is warmer than the air. 

 Thus condensation of water vapor 

 is hindered. 



It has been found that olive oil 

 when spread^out over a calm sea will 

 begin immediately to lift the fog. 

 "Grass islands" entirely obscured by 

 the fog bank at only a few yards 

 have been discerned as far away as 

 a mile, in line with the clearing made 

 by the oil. 



Wind, of course, tends to counteract 

 the effect of the oil, except in the 

 direction in which it is blowing. 



Those of us interested in science, engineering, invention form a kind of guild. 

 We should help one another. The editor of The POPULAR SCIENCE Monthly is 

 willing to answer questions.
