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 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.

��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.
