The "gasoline horse" which rumbled through Chicago's 

 streets, guided by reins in the hands of the driver 



A Gasoline Horse Which Is Guided 

 With Reins 



yVN entirely new type of gasoline "war 

 jLjL horse" was driven through the streets 

 of Chicago recently. It was a two-wheeled 

 gasoline tractor controlled by two reins 

 like those of a harnessed horse. 



The "gasoline horse," it is said, could be 

 loaded with dynamite and guided across 

 "No Man's Land" with 

 reins a thousand yards 

 long, and exploded in 

 the enemy's country, 

 while the driver re- 

 mains at a safe distance. 

 The principle is the 

 same as that of the 

 torpedo car, described in 

 the April Popular 

 Science Monthly. 



The exhibition of the 

 machine was made by 

 army officers conducting 

 a campaign for recruits 

 in the city. A three-inch 

 field gun and several 

 caissons were drawn be- 

 hind it, the driver being 

 seated on a caisson at a 

 conspicuous distance 

 from the "horse" so as 

 to be able to show off 

 the virtues of his "steed" 

 to the best advantage. 

 The machine responded 

 to his lightest touch.

* 'Making Money'* By Wireless — ^A 

 Counterfeiter's Scheme 



THE latest alleged "wireless" swindler 

 is Max Hans Ludwig Wax, whom the 

 New York police have recently arrested. 

 Our photograph shows Wax's "Money 

 Making Machine," with which he is said to 

 have mystified his victims throughout the 

 United States. It is easy to see how the 

 flashing of frosted lamps 

 on the box-front, to- 

 gether with the hum- 

 ming and crackling of 

 the rotary and fixed 

 spark gaps, the sputter- 

 ing of the relays and 

 their choke-coils, and 

 thecomplex adjustments 

 of many switches, tun- 

 ing coils, condensers and 

 potentiometers would 

 puzzle even a self-styled 

 "expert." In the box is 

 a miscellaneous collec- 

 tion of meters, coils, 

 switches and other in- 

 struments, sufficient to 

 transmit messages for 

 twenty or thirty miles 

 and to receive from 

 much greater distances. 

 The radio instruments 

 were probably mere 

 "bHnds" to make the 

 strongest impression up- 

 on the gullible victims.
