No More Rubber Tires in Germany 

 — Except for the Kaiser 



GERMANY had a little rubber in the 

 " early days of the war, but she soon 

 became reduced to smuggling in what she 

 could through the mails. Great Britain 

 soon closed this channel, also the traffic 

 in automobile tires which were being im- 

 ported through Sweden. Now, only the 

 Kaiser rides in an automobile boasting 

 real rubber tires. Everyone else has to 

 bump along on tires filled with cork, 

 paper or even rags.

How could anyone resist the mute appeal 

 of these canine helpers in a good cause? 



Dogs as Patriotic Helpers in 

 a Good Cause 



DURING "Thrift Week" in Los Ange- 

 les these two dogs, Spike and Pride, 

 took an active part in the campaign for 

 selling thrift stamps. To say that they 

 were successful only mildly expresses the 

 result of their joint efforts. Spike and 

 Pride made a mute 

 but effective ap- 

 peal to the patriot- 

 ism of the crowds. 

 Pride carried a bas- 

 ket filled with 

 thrift stamps, while 

 Spike, carrying a 

 tin box with the 

 inscription "I'm 

 the Cashier," was 

 soon loaded down 

 with the weight of 

 the coins dropped 

 into his cashbox. 

 The two dogs to- 

 gether disposed of 

 hundreds of stamps 

 every day and thus 

 bravely helped the 

 good cause.

Locating Splinters Made Easy By 

 This Device 



TO one of the New York hospitals, lo- 

 cated in a district where the manu- 

 facture of clothing is conducted on a large 

 scale, so many workers came every day 

 with splinters, parts of needles, and for- 

 eign bodies in their fingers, that it became 

 necessary to provide some simple method 

 of locating foreign bodies without resort- 

 ing to X-Rays. The contrivance shown 

 in the picture was the outcome of some 

 experimenting by the house physicians. 

 It has proved to be of great assistance in 

 numerous instances since its adoption. 



A piece of black woolen cloth, eight 

 inches square, was fastened to a square of 

 adhesive plaster of the same size. In the 

 center an oval opening was made, measur- 

 ing five-eighths by one-half inch. By 

 placing this over an 

 electric light sup- 

 plied with a re- 

 flector and placing 

 the finger of the 

 patient over the 

 hole, excellent 

 transillumination 

 could be obtained, 

 and any foreign 

 body in the finger 

 easily located. 

 This little appara- 

 tus has resulted 

 in a saving, 

 both in time and 

 money, for an X- 

 Ray machine is 

 both awkward and 

 patient is placed over rather COStly to 



can quickly be located operate.
