Here is a group of English railroad employees worship- 

 ping the deity, Tea, under unusual circumstances 



If You Work Hard, Ea| 

 More Pancakes 



IT is a common mistake to 

 suppose that to get the 

 necessary strength to do 

 hard manual labor, a heavy 

 meat diet is necessary. This 

 is far from correct. Muscu- 

 lar labor does not materially 

 affect the demand for miner- 

 als and proteins, but rather 

 for starches, fats and sugars, 

 Therefore any additional 

 wastage through muscular 

 effort could be much better 

 repaired by pancakes and 

 sirup than by roast beef, for 

 as much moisture and heat 

 are wasted as tissue, so it is 

 fuel that is required.

England Must Have Its Tea, Even If 



It Is Wartime 



^HERE are tea-parties and tea-par- 

 ties. Some, like the Boston variety, 

 have become historically famous; others 

 have not. The tea-party in the picture, 

 with its unconventional setting and sit- 

 ting, is not exactly a "pink tea" patron- 

 ized by the upper-ten-dom. It is really 

 an interesting picture of wartime Eng- 

 land. The women in the group are rail- 

 road employees in London. Chilled to 

 the bone by the penetrating cold of an 

 unusually severe winter day, these hard- 

 working young women gathered in a 

 secluded corner during a lull in their 

 work, and warmed 

 themselves and 

 gained new energy 

 by sipping piping 

 hot tea. 



Tea seems to be 

 a sine qua non 

 with our English 

 cousins. War or 

 no war, teatime is 

 sacred. Appar- 

 ently, judging by 

 the war pictures, 

 evt n the Tommies 

 at the front re- 

 ligiously observe 

 it and at least it 

 is stimulating.

How Finger Prints Are Studied With 

 a Handy Portable Desk 



FINGER prints of criminals are photo- 

 graphed and filed away for reference. 

 A filing cabinet which makes it easy to 

 handle the photographs has a board 

 hinged to the top which can be set at any 

 desired angle. A place is provided for a 

 magnifying glass through which the finger 

 prints may be studied. A mounting 

 board which is ruled into spaces for right 

 and left hand prints makes the examina- 

 tion of the photographs very simple. 



When not in use, the board drops down 



into the top of the case. Under the board 



is a drawer which provides the necessary 



space for filing the 



photographs. 



This filing sys- 

 tem makes it con- 

 venient to classify 

 the thousands of 

 prints by various 

 groups and sec- 

 tions, so that any 

 particular set or 

 sets can be ob- 

 t a i n e d imme- 

 diately for study 

 or comparison 

 with others. The 

 whole thin^ is 

 corn pact and con- 

 venient.
