 Curing Soldiers' Wounds with 

 Granulated Sugar 



DESPITE the terrific fighting in 

 the present war there will not 

 be so many one-armed and one- 

 legged men as there have been in 

 past wars. The reason rests with 

 the surgeons and the methods of 

 treatment given the wounded. Dr. 

 Alexis Carrel has been doing some 

 remarkable work in France. He has 

 made an effective antiseptic from 

 sodium hypochlorite and boric acid. 

 But for real ingenuity credit has to 

 be given to Dr. Erich Meyer, of Ger- 

 many. He has cured wounds with 

 sugar. 



After washing out the wounds he 

 has dressed them with ordinary granulated 

 sugar covered with a compress, renewing 

 the sugar every second or third day. This 

 simple treatment, according to Dr. Meyer, 

 has been notably successful. In a number 

 of instances amputations have been pre- 

 vented because the wound was sugar-cured. 



This New Furnace Burns Soft Coal and 

 Cleans Its Own Radiator 



IN view of the coal 

 shortage and the ne- 

 cessity of burning more 

 soft coal than ever be- 

 fore for heating apart- 

 ments and private 

 houses, a new furnace 

 that has a self-cleaning 

 radiator which does not 

 become clogged with 

 soot is timely. By 

 means of a diving flue 

 the soot is deposited 

 in the fire chamber be- 

 fore it has a chance to 

 enter and stop up the 

 flues. The radiator may 

 also be used for burning 

 hard coal, coke, or wood. 

 The furnace is so con- 

 structed that it may be 

 used for either a single 

 register or pipeless fur- 

 nace, or with the radi- 

 ating pipes. It has the 

 up-to-date appliances 

 for humidifying the air 

 and securingcleanliness 

 and ventilation.

Calibrating Water Current Meters 

 Which Measure the Flow of Rivers 



THE little railroad shown in the pho- 

 tograph above is not for the purpose 

 of joy-rides for school-boys, as a youngster 

 might think at first glance. It is a conveyor 

 for an instrument of large name and im- 

 portant purpose, which is used to calibrate 

 water current meters, instruments used by 

 civil and hydraulic engineers for measuring 

 the velocity of the 

 water flowing in rivers 

 and open channels. 

 These velocity meas- 

 urements, in connec- 

 tion with the cross- 

 sectional area of the 

 stream at the point 

 where the velocity 

 measurements are 

 taken, are used for 

 computing the quan- 

 tity of water being dis- 

 charged by the stream 

 in a given time. Such 

 statistics are necessary 

 in many engineering 

 projects, such as water 

 power development, ir- 

 rigation and flood 

 prevention. 



Hundreds of such 

 calibrations are made 

 annually by the United 

 States Geological Sur- 

 vey, the United States 

 Reclamation Service 

 and other branches of 

 the Government.
