What? Tail-Lights for Mules! Yes, 

 Here They Are

THE 

 usee 



iiiiik-, the most 

 L-(l and abused of 

 pack animals, doesn't know- 

 much about hitching his 

 wagon to a star, but inven- 

 tive man lias come along and 

 has hitched a star to the 

 mule's tail. All this has been 

 done to protect the mule's life, 

 and to pre\ent him from losing 

 himself and making trouble when 

 he is but one mule in a drove of mules. 



Recently a disastrous accident occurred 

 near Los Angeles when a woman dri\Mng an 

 automobile along the highway ran into a 

 drove of mules. The automobile was 

 wrecked, the woman was injured, and two 

 of the mules were killed. A court action 

 was later filed against the owner of the 

 mules, and the woman was awank'd 

 substantial damages. 



It would seem at first thought that the 

 owner of the mules rather than the auto- 

 mobilisl was entitled to damages; but the 

 judge must ha\e known something about 

 mules and undiTstnod the odds. 



Asa risiill nf the accident the mule owner 

 flevised a tail-light to be worn b\' his 

 animals after dark. It is a light of ih<' 

 simple rellecloxope type, such as is used 

 by bic>clists. When a pack train of mules 

 is driven along at night each mule is 

 adorned with a light. This eii.ibles the 

 flri\er, far in the riar of the lead mule, to 

 note the position rtf e.ich animal in line and 

 the direction he is taking. 



The Tiniest Motorcycle To Be Used 

 in the Army 



SOMK interesting e.\perinient- 

 Were made recently by t'aptaiii 

 Irank E. Kvans of the L'nited Slates 

 Marine Corps with a view toward 

 establishing the practicability of a 

 small motorcNcle designed by Hugo 

 C Gibson. 



.\ private, equipped in heavy 

 marching order, tried out the ma- 

 cliine. He had had no previou- 

 experience with automobiles or m( - 

 torcyclcs. Vet his success in operat- 

 ing it has led to the belief that it 

 would lie a welcome addition to the 

 hglning ecpiipment of our soldiers. 

 The machine will carry as much 

 as three hundred pounds and 

 attain a speed of iwenty-fi\e 

 miles an hour, although its 

 weight is but fifty pounds. It 

 takes hills easih'. Private 

 I)a\is, who tried it out, found 

 no difficulty in ascending a 

 fourtcen-degree incline. 



The machine is so small 

 that it will turn around sharj) 

 corners without danger. It is 

 so light that it may be lifted 

 o\er any ordinar\- obstacle. One 

 of the tests consisted in riding it 

 up to a four-foot fence, stopping the 

 engine and lifting the machine over the 

 fence, all of which was done with ver\' 

 little delay. If the man who delivered the 

 famous message to Garcia had had one of 

 these his task would have been easier. 



The dimensions of the little machine 

 are forty-eight inches b\- nine inches In 

 eighteen inches. It is almost small enough 

 to be a plaything. Vet it will carr\- 

 three lunidred pounds for fifty miles at 

 ,wi operating expense of ten cents. 



It looks tiny, but it will cnrry three hvin- 

 drcd |K>uiidti at twenty five miles an hour
