Getting Your Change by Machine 

 From the Cashier 



IN busy stores and restaurants of the pay- 

 at-the-desk variety, a new device for 

 handing change back to the customers is 

 proving popular. 

 You simply hand in 

 the check and the 

 money through the 

 cashier's window. 

 When she has made 

 the change she de- 

 posits it in the open- 

 ing of a cylinder, as 

 shown in the illus- 

 tration. By giving 

 a slight upward push 

 on the bottom of the 

 cylinder you cause 

 the two halves of the 

 false bottom of the 

 cylinder to open out, 

 and the coin drops 

 down into your 

 palm. Or you can 

 obtain your change 

 in the usual way, 

 by sliding it off the 

 opening of the cylin- 

 der into your hand. 

 Of course the device 

 will not work with 

 bills or soda checks.

A Fishing Light to Lure the Fish 

 to the Bait 



WE have the word of the fishermen for 

 it that fish are not unlike other 

 creatures of the earth in regard to curiosity. 

 They are as interested in what goes on 

 below sea level in their subterranean home 

 as we are in what takes place above it. 



The fish 



hook with 



its bait floats 



just in front of 



the light. The depths 



are adjusted by cork floats 



William J. Ryan, of Sapulpa, Oklahoma, 

 has made good use of this bit of fish 

 psychology in devising his fishing ap- 

 paratus. He suspends an electric light and 

 a fish hook near each other under the 

 water. The fish are attracted to the light 

 like moths to a flame. 

 Near the light they 

 see the bait, investi- 

 gate, and then re- 

 pent when they find 

 themselves on land. 

 Within a wooden 

 box large enough to 

 hold the entire ap- 

 paratus the inventor 

 places two batteries. 

 Wires run from these 

 batteries to a lamp 

 Which is suspended 

 in the water. Rub- 

 ber tubing around 

 the wire keeps out 

 the water, and so 

 does a glass jar about 

 the lamp. The 



depth of the light 

 and the hook in 

 the water is ad- 

 justed by cork 

 floats. Need- 

 less to say, the 

 brighter the 

 light the more 

 curious and 

 careless are the 

 fish, all of which 

 delights the 

 fisherman. 



It Costs a Fortune to Keep French 

 Army Officers in Cars 



JOY riding seems to be a regular sport of 

 French army officers. According to 

 charges of reckless extravagance made 

 against the touring-car section of the 

 French army, the officers think that the 

 cars they use are their own private prop- 

 erty. Indeed, competition is rampant, 

 each officer wanting the best machine and 

 the most expensive assortment of acces- 

 sories, says the report. The cost of 

 twenty-six cars for the general head- 

 quarters staff cost one hundred and 

 seventy thousand dollars. Three thousand 

 dollars is the annual upkeep per car. The 

 only remedy, as France now sees it, is to 

 refuse to allow any officer, no matter what 

 his rank, to have a personal car.
