A Medicine Cover Which Eliminates 

 All Guesswork on the Part of the Nurse 



MEDICINE that is to be taken a spoon- 

 ful at a time, at intervals, should 

 always be covered, especially if the 

 sick person is lying in a 

 room where the windows 

 are open and dust enters. 

 It is also equally im- 

 portant that the doses be 

 administered at the pre- 

 cise time stated by the 

 physician. It goes with- 

 out saying that benefi- 

 cial results can not be 

 expected when medicines 

 are administered irregu- 

 larly, which is so often 

 the case when memory 

 is relied upon or where 

 there are several persons 

 waiting upon the sick 

 one. 



A medicine cover 

 which will remind you 

 when the next dose 

 should be taken, is a 

 recently marketed arti- 

 cle. The face of the 

 cover, which is made of 

 wood, is neatly colored and numbered from 

 one to twelve in clockwise fashion. An hour 

 hand and a minute hand are pivoted to the 

 center. It is topped by a sympathetic ap- 

 pearing little figure by which the cover is 

 lifted. After each dose is administered, the 

 hands are set forward to the proper time for 

 the next dose. 



The minute and hour hands on the 

 cover tell the nurse exactly when 

 the medicine should be 



Shielding the Munition Worker 

 Behind Steel Walls 



FILLING the large shells is not the only 

 dangerous task in the munition plants. 

 Loading the shell primer and fuses in which 

 only a very small quantity of explosive is 

 used, is almost equally hazardous. A de- 

 fective fuse, for instance, is likely to go 

 off and to ignite piles of fuses and 

 powder that are near it. This 

 source of danger has been found so 

 great in the experience of E. P. du 

 Pont, of Wilmington, Delaware, 

 that he has designed a special load- 

 ing house to protect the workers. 



The operator is separated from the ex- 

 plosive material by a steel partition. Only 

 the few grains of powder required to fill one 

 or two fuses are at hand. If these grains go 

 off, little harm is done. If the big piles 

 should be accidentally ignited, practical- 

 ly the entire force of the 

 explosion w'ould be spent 

 in the open air, on the 

 other side of this par- 

 tition. 



The trucks that han- 

 dle the powder supply 

 and that take away the 

 stacks of the finished 

 products, all run on the 

 outside of the partition, 

 which is really the out- 

 side of the building. The 

 loose explosive is placed 

 in the large conveying 

 trays that are shown. 

 By tapping these slant- 

 ing trays, enough pow- 

 der slides through the 

 little neck of the tray 

 to allow for a few fillings. 

 This powder is then 

 wrapped up in the fuse 

 fabric and the product is 

 immediately passed out 

 on another tray near by. Fuses, that are 

 wrapped too tightly or are made imperfect 

 in any way, are slid down a chute into a 

 shallow bucket to be taken away. In this 

 way no one touches the dangerous parts. 



The entrance of women workers into muni- 

 tion factories has inspired many foremen to 

 make extra humanitarian efforts in behalf of 

 their employees and those dependent upon 

 them for support.
